DETAILED DESCRIPTION OF THE INVENTION
There are herein provided methods and apparatus useful for diagnostic imaging systems. The apparatus and methods are illustrated with reference to the figures wherein similar numbers indicate the same elements in all figures. Such figures are intended to be illustrative rather than limiting and are included herewith to facilitate explanation of an exemplary embodiment of the apparatus and methods of the invention.
As used herein, an element or step recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural said elements or steps, unless such exclusion is explicitly recited. Furthermore, references to “one embodiment” of the present invention are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.
Also, as used herein, the phrase “reconstructing an image” is not intended to exclude embodiments of the present invention in which data representing an image is generated but a viewable image is not. Therefore, as used herein the term, “image,” broadly refers to both viewable images and data representing a viewable image. However, many embodiments generate (or are configured to generate) at least one viewable image.
Herein described is a simplified user interface that prescribes, creates, and presents images ready for a radiologist to review. Technical effects include that this user interface addresses four primary workflow enablers, usability, enterprise interoperability, clinician flexibility/context specific Rx, and clinical performance. Usability means the user interface is learnable, efficient, memorable, error reducing, and a generally satisfying user interface. The interface includes a dashboard that tells the story of the exam and a “Procedure at a glance” that uncovers hidden information and removes clicks and checks. In one embodiment, organ-based protocols eliminate detailed parameter concerns for most exams. Enterprise interoperability means the scanner can retrieve data from a hospital Radiological Information System (RIS). The retrieved data includes lab values, patient location, and patient history for structured report text pages. The user interface allows information to be sent both to the RIS from the scanner and from the RIS to the scanner. The user interface also provides, in one embodiment, the ability to edit and/or group procedure codes and communicates completion of the grouping and/or editing to the RIS. An Auto-transfer of images by image range or “named volume” is provided in one embodiment. Consistent presentation of images by preserving measurements, user annotations, and filters is provided in another embodiment. Structured reports for dose page, exam and series text page, and exam and/or protocol notes are provided in one embodiment. Clinician flexibility/Context specific Rx means prospectively setting configurable image and/or application layouts in combination with user controlled automatic start of applications. Prospectively setting windows, algorithms, and projections based upon an organ interrogation system is done in one embodiment. The organ interrogation system interrogates a user for which organ is to be scanned. All the above can be generated automatically and simultaneously as previously designed exam by exam in organ-based protocols. Clinical performance is reducing variance and improving consistency of imaging results exam to exam. “Mistake Proofing” with automated bolus timing is provided in one embodiment. Streamlined workflow is provided by real-time control of contrast injection from the scanner user interface in one embodiment. This removes potential errors of starting sequences from different control interfaces and offers the ability to program or auto-adjust injection sequences. This allows for using less contrast agent and improves a patient's experience.
The herein described interface is a simplified user interface (SUI) for Diagnostic Imaging (DI) (SUIDI, also herein referred to as a Diagnostic Imaging Simplified User Interface DISUI, and SUI, and all those acronyms are used interchangeable herein). The SUI generally provides users the ability to choose a patient for an exam, associate a patient exam with a desired diagnostic imaging protocol that specifies: scan, timing, contrast timing, reconstruction, image display and/or review, and image processing required to make images ready for Radiologist review. In different embodiments, the SUI provides a bi-directional interface to a Hospital RIS system. The SUI provides support for enterprise interoperability with the scanner retrieving RIS data such as, for example, but not limited to lab values, patient location, and patient history for structured report text pages.
The SUI provides the ability to edit and/or group procedure codes and then the SUI communicates completion of the editing or grouping to the RIS.
The SUI provides a means to select a patient for a DI exam. The SUI provides a means to associate a DI protocol with a patient exam. The SUI provides a means to create and/or edit and/or select organ-based protocols. The SUI provides a means to create various protocols providing desired ready for Radiologist read outcomes for specific exams. The SUI provides a means for consistent presentation of images by preserving measurements, user annotations, and filters. The SUI provides support for structured reports for dose page, exam and series text page, and exam and/or protocol notes.
The SUI is common across multiple DI modalities such as CT, PET, MRI, etc. This use of a single interface across different modalities allows technicians and other users to be easily cross-trained on the different modalities.
The SUI is learnable, efficient, memorable, error reducing, and generally satisfying to users. The SUI includes, in one embodiment, a dashboard that communicates effectively the “Procedure at a Glance” for a technologist to easily perform a quality assurance review.
The SUI specifies a scan, scan timing, contrast timing, reconstruction, image display/review, and provides an application based image processing requirement that makes images ready for Radiologist review.
The SUI automatically starts image processing applications in the background (application auto-launch), under a user's control for review. The SUI supports configurable image display/review layouts that users can create/edit and save. The SUI allows users to easily change Patient Exam contexts for multitasking workflow.
The SUI supports clinician flexibility/context specific Rx means prospectively setting configurable image/application layouts in combination with user controlled automatic start of applications. The SUI prospectively setting windows, algorithms, and projections is based upon an organ interrogation system. All of this being generated automatically and simultaneously as previously designed exam by exam in organ-based protocols.
The SUI supports X-ray dose reduction functionalities and supports a scanner interface for contrast management/injection. The SUI supports appropriate automation of manual contrast timing procedures. The SUI has graphical prescription capability. The SUI has retrospective prescription capability. The SUI has enhanced Graphical prescription from any diagnostic imaging DICOM image.

Diagnostic Imaging Simplified User Interface Relationships to Imaging Chain
- 1. The DISUI system typically includes, but does not have to, two high definition LCD monitors. The left monitor is dedicated to patient and protocol selection and detailed Exam prescription (Rx). The right monitor is dedicated to image review and processing. The DISUI system is independent of monitor configuration and can support 1 through “N” monitors.
- 2. Users enter the system from a password protected HIPAA log in screen on the left monitor.
- 3. Successful log in transitions users to a Modality Work List (MWL) screen. Here users may update/refresh the screen and then choose the appropriate patient for a diagnostic imaging exam.
- 4. Patient selection from MWL transitions users to the top level View/Edit prescription (Rx) screen. At this point, in the patient exam, users can either perform a quality assurance review of the protocol details for the selected procedure or detailed parameter edits. Dashboard user interface elements tell the story of the exam. This exam dashboard includes:
- a. At A Glance/Quick Check parameters
- b. Scan parameters
- c. Timing parameters
- d. Contrast Management Rx
- e. Image Reconstruction and Image Review/Processing Applications Prescription (Rx)
- 1. Image reconstruction parameters
- 2. Image Review/Processing Applications Rx and parameters
- 3. Configurable display/review layouts
- 4. Customizable view port definitions
- 5. Application Auto-Launch
- 6. Application controls
- f. Image range prescription for output functions including:
- 1. Network
- 2. Hard Copy Filming
- 3. Long term storage image archive
- 4. Exam Split
- g. Patient Monitoring
- h. Patient Orientation Prescription (Rx). Users review the Rx and in 80 to 90% of all cases are satisfied enough to “Confirm” the first scan series. In CT exams, this is typically a “Scout” scan. CT Scout scans provide images from which adjustments can be made to tune scan series scannable volume/s for individual anatomical differences.
- 5. The right monitor is dedicated to image review and processing. It also is enabled with the knowledge of a patient exam or session context. This allows users to decouple prescription on the left monitor from image review/processing on the right monitor. Users may choose the patient exam/session context they wish to work on. This enables “multi-patient exam/session multi-tasking”. While the present patient is being prepped and perhaps scanned by one technologist in the scan room, a second technologist can be completing the image review/processing for another perhaps previous patient. Users choose their desired patient exam/session context and then have full control over the image review/processing and auto-tasks (reconstruction, networking, hard copy filming, and exam split) associated with that patient exam/session. This control includes pausing and resuming tasks, adding tasks, and deleting tasks. It further includes full suites of detailed controls tied to the image review/processing tasks being performed. Users may choose, at this point in the exam, to switch the exam/session context to the present exam/session and review the scout images as they are reconstructed and displayed on the right monitor.
- 6. Both monitors provide users with desktop management capability. Desktop management allows users to navigate at a high level to wholly different functional areas including:
- a. Modality Work List
- b. Scanner specific utilities
- c. Image Management Browser
- 7. CT scanning protocols typically consist but are not limited to at least two scan series with the first scan series typically being a Scout scan series. With successful completion of the Scout scan/s users typically progress to the next scan series. On the left monitor is a Workflow Task Manager that allows users to select the next scan series in the overall patient procedure/protocol.
- 8. Selection of the next scan series from the workflow task manager transitions the left monitor to the view/edit Rx screen containing the exam dashboard uniquely defined for that scan series. The right monitor automatically transitions to a special prescription function screen called Graphical Prescription (Rx). Users may make specific adjustments in Graphical Rx to tune the scan acquisition for patient differences. In addition, dedicated graphical views for other image processing applications are also provided to help users dial in their Rx for individual patients. This graphical Rx activity occurs on the right monitor. Users once again can choose to quickly review the unique exam dashboard for this series on the left monitor and then confirm the scan acquisition or edit any or all parameters they desire to change. In 80-90% of all cases, the exam dashboard Rx should be correct requiring little or no editing beyond those graphical adjustments made on the right monitor.
- 9. Once a user confirms the next scan series, the right monitor transitions to an image review/processing presentation tuned specifically for this scan series.
- 10. Image range prescription for output functions including networking, hard copy filming, archiving, and exam split are available to users in every reconstruction for every scan series within a patient exam/session.
- 11. Patient monitoring is available in Cardiac CT studies and perhaps in others as well at every point in the patient exam. Patient Monitoring displays time varying parameters of the patient being imaged in both graphical and textual form. These may include one or more of the following specific element definitions including:
- a. Vital sign, heart rate with EKG trace vs. time and real-time textual heart rate readout.
- b. Vital sign, respiration rate trace vs. time and real-time textual respiration rate readout.
- 12. Patient orientation can be reviewed/edited at any point in the patient exam. Patient Orientation Prescription (Rx) allows users to specify landmark location and desired patient orientation before scanning. These selections and parameters can be adapted/changed for the specific procedure being performed. These selections and parameters are part of a predefined protocol created by users to perform a desired procedure
FIG. 1 illustrates a screen 10 of the DISUI where a user may select a scan selector option 12, a patient orientation option 14, a patient monitoring option 16, a scan Rx 18, and a reconstructions and applications parameters option 20. Additionally, screen 10 illustrates a Modality Work List tab 22, a tools tab 24 and a patient tab 26
FIG. 2 illustrates a screen 30 of the DISUI with four configurable viewports 32, a session manager option 34, and a controls option 36. Screen 30 also shows a workflow manager tab 38 and a service tools tab 40.
FIG. 3 shows a dashboard 50 of the DISUI that tells the story of the exam by setting forth the order of the different procedures and their descriptions. Note an Add button (A) and a Delete button (D) on bottom. In FIG. 3, the first procedure a Scout scan is in process (IP), and the user is able to pause the procedure. FIG. 3 also shows. a) At A Glance/Quick Check parameters, b) Scan parameters, c) Timing parameters, d) Contrast Management Rx and e) Image Acquisition parameters such as dose.
FIGS. 4a, 4b, and 4c (collectively called FIG. 4) is a screen shot of the DISUI wherein FIG. 4a is the left, 4b is the center and 4c is the right and is partially truncated on the right side as explained below. Starting with 4a, there is a current patient tab at the top. Beneath the current patient tab is a scan protocol area with an example 4.2 Cardiac protocol which includes a series of scans starting with a scout scan and then a helical localizer scan, followed by an axial scan with a timed bolus injection, and ending with a cardiac helical scan with parameters SSSeg, 0.625 mm slice thickness, and large SFOV (Scan Field of View). SSSeg stands for “Snapshot Segment” which is a special Cardiac Helical reconstruction algorithm. The algorithm is tuned to make optimal images at certain heart rate ranges for example 60 beats per minute to 90 beats per minute. As patient heart rate falls out of or exceeds a certain range we would recommend a different reconstruction algorithm to better match up with the patients real heart rate. The DISUI allows a user to repeat the series, to select a new protocol, and to save the protocol. The DISUI also includes a scan parameter area where the user can perform a quick check as explained above, can view scan parameters, timing parameters, select a contrast, add bolus information, and comments/notes. Below the scan parameter area is an optimize button, a SmartPrep button, a Priority Reconstruction button, and a one more button. “One More” is a shortcut prescription for 1 more scan beginning at the Rx'd End Location and then persisting for 1 revolution of the scanner gantry. So in a 40 mm scanner this button would scan an additional 40 mm (1 revolution) and reconstruct an image from this scan data. This is typically used to cover the scenario where a scan was a little short and needed to be lengthened to obtain proper patient coverage. Nearby is an End Scan button and a display of parameters, such as kV and mA for the x-ray tube voltage and amperage, exposure time, thickness, helical pitch, SFOV (Scan Field of View), auto voice, voice light, timer, DFOV (Displayed Field of View), rotation speed, and interval. Auto-Voice is a function that “plays” pre-recorded breathing instructions for the patient during the exam. “Lights” are special iconified lights in the scanner gantry that patients can see, the lights have special icons that indicate “hold your breath” or “breathe” this is provided for patients that are more visually oriented than verbally oriented. Returning to the top of FIG. 4a, there is a patient position area that allows the user to specify how the patient is positioned in the scanner, and to add a scan number. There is also a localizer button. Below the localizer button is a recon (i.e., reconstruction) parameters area that allows for exporting the parameters. Next to the reconstruction parameter area is an auto reformat area including options to export and save the auto reformat parameters such as a different DFOV then as originally displayed and any re-centering information both Right/Left and Anterior/Posterior, both in mm.
Referring now to FIG. 4b, at top is an EKG of graph with buttons to pause and resume the scan. The screen displays reconstruction type, matrix size, reconstruction options, R to R interval, and Phase Increment. Buttons include a Biopsy Rx button, a SmartPrep button, a Preview button, and an Optimize button. Information displayed include the number of images, a Ct dose weighted (CTDI/w), a Dose Length Product (DLP), a dose, a projected DLP, and an accumulated DLP. Nearby is a confirm scan button the user can press to confirm. There is a CardIQ tab a user may select to access a CardIQ Function Analysis tool, which is an application used to display cardiac CT images and semi-automatically or manually calculate left ventricular (LV) and right ventricular (RV) functional parameters. One embodiment includes a lung VCAR tab were VCAR means Volume computer-assisted reading. The application is optimized to perform assessment of cardiac function using multi-phase, multi-slice cardiac CT images. Toward the right side of FIG. 4b is an area that displays the current patient's name, and the scan tasks, series number, and statuses. Tasks may be added, deleted, paused, and closed. There is also a list of “image processing tasks” under the banner of “Exam 23”. These are user selectable image review/processing tasks that map to the left screen application dashboard. So for example, the “Auto-Reformat” task maps to “Auto-Reformat” in the left screen dashboard. These tasks or applications are Rx'd on the left and execute and are user controlled on the right. Left Click selection of a task in this list causes it to “come forward” and be displayed to the user.
FIG. 4c illustrates the screen displays six viewports simultaneously. In addition to the four viewports shown in FIG. 4 as Auto Film, Auto-Reformat Oblique, free review viewport, Auto-Reformat Sagittal, there are two additional viewports which are truncated in FIG. 4c. The viewports shown truncated are Auto-Reformat Axial and Auto-Reformat Coronal.
FIG. 5 illustrates a screen shot showing a centrally disposed main image section 100 wherein the user can select an area of interest as illustrated. Above the main image section 100, the patients name and ID number are displayed. An exam manager button 102 when selected displays an exam manager window 104 showing the exam number, the patient names, and number of tasks for each exam. Exams can be added, closed, and opened. Also displayed are tasks, protocols, and states of the tasks. Tasks can be deleted, paused, closed, and opened. On the right of FIG. 5 are a plurality of images including a recon 1 (R1) of two which is displayed with a drop down to move to the second recon. A reference image can also be displayed such as the scout image that was used to select recon 1. Note other images include a Auto Reformat image Chest 1, an Analysis Cardiac IQ image, an Analysis Application 2 image, and an Exam Split Chest image. Each image can be selected to be displayed in main image section 100. FIG. 5 also illustrates options to send the data over a network to particular Doctors or other clinicians, or to another location. The data can be archived or sent to film. In the film example, the user can both select the particular printer to send to and the layout of the images.
