As in-office medical imaging devices (e.g., ultrasound imaging systems) have become more affordable their popularity and utilization at the point-of-care (e.g., in the physician's office) has increased. For example, healthcare providers are currently using ultrasound machines in departments throughout the healthcare system for the purposes of procedural, diagnostic, and physical exams. The use of these imaging devices at the point-of-care and outside of the conventional radiology workflow has brought about the need for proper storage, documentation, billing, and peer review of these image studies.
Currently, the problem experienced by healthcare organizations with in-office imaging is that the organizations do not have an efficient and reliable method to capture and attach the correct patient metadata to image studies performed in the office. Many areas outside of radiology and cardiology acquire images at the point-of-care during an office visit and would benefit greatly from getting a DICOM order to their imaging device without purchasing and setting up a separate Radiology Information System (“RIS”) to manage the ordering, scheduling, patient reporting, and image management processes. Additionally, with in-office imaging, the resulting clinical images are often not properly stored in the electronic health record (“EHR”), leading to orphaned studies that remain in quarantine due to bad patient data or patient images stored on jump drives, CDs, and disks in an unsecure environment.
Thus, there remains a need to provide a medical image management system and workflow solution for medical imaging that occurs outside of the conventional radiology workflow.
As modalities started to support the digital display of images on workstations connected to the acquisition device, Picture Archiving and Communications Systems (PACS) came to market. These centrally store images and provide radiologists with the tools to read studies on networked computer monitors, replacing both film and modality workstations.
The present disclosure addresses the aforementioned drawbacks by providing a medical imaging workflow management system that includes a client, a database, and a worklist broker. The client is implemented with a hardware processor and a memory, and is configured to generate a medical imaging order comprising study metadata associated with an imaging device and a patient to be imaged by the imaging device. The database is in communication with the client to receive the medical imaging order from the client and store the medical imaging order therein. The worklist broker is implemented with a hardware processor and a memory and in communication with the database. The worklist broker is configured to generate a DICOM order by transposing the study metadata contained in the medical imaging order into a DICOM format; store the DICOM order to a worklist; receive a query associated with the medical imaging order from the imaging device; identify the medical imaging order in the worklist; retrieve the medical imaging order from the worklist; and send the DICOM order and metadata contained therein to the imaging device to be attached to images obtained therewith.
It is another aspect of the present disclosure to provide a medical imaging workflow management system that includes a worklist broker implemented with a hardware processor and a memory. The worklist broker is configured to receive a query from a medical imaging device and identify orders in response thereto; retrieve a medical imaging order from a database; transpose metadata contained in the medical imaging order to a DICOM format; and provide the transposed metadata to the imaging device to be attached to images acquired therewith.
It is another aspect of the present disclosure to provide a medical imaging workflow management system that includes a client implemented with a hardware processor and a memory. The client is configured to display image orders associated with medical images stored in a long term archive; identify medical images stored on the long term archive as being quarantined medical images; update metadata associated with the quarantined medical images; remove the quarantined medical images from quarantine; and reprocess a C-store of an image study to the long term archive when the metadata associated with the quarantined medical images has been updated.
The foregoing and other aspects and advantages of the present disclosure will appear from the following description. In the description, reference is made to the accompanying drawings that form a part hereof, and in which there is shown by way of illustration a preferred embodiment. This embodiment does not necessarily represent the full scope of the invention, however, and reference is therefore made to the claims and herein for interpreting the scope of the invention.
Described here are systems and methods for managing medical images acquired in a point-of-care setting outside of a conventional radiology workflow. As will be described below, the medical imaging workflow management system of the present disclosure implements a dual workflow configuration, in which an “orders first” workflow and an “images first” workflow are implemented.
The dual workflows provided by the system described here allow clinicians to make their decision to image a patient either in advance via the “orders first” workflow, or on the fly via the “images first” workflow, thereby freeing the clinician to care for patients without worrying about whether an imaging order has been properly placed. The medical imaging workflow management system of the present disclosure provides a method for the clinician to later add order information to the images in an efficient manner. Alternatively, if there is no reason to keep the images that were obtained without an order first, the image study C-store job may be canceled by the user at the client.
In the “orders first” workflow, the medical imaging workflow management system of the present disclosure attaches the image order to a provider's pre-existing event and does not require the use of a Radiology Information System (“RIS”), thereby eliminating the need for making an additional device appointment and processing the exam through the RIS.
The client 12 can include a hardware processor, a memory, one or more inputs, and a display. In some examples, the client 12 can include a desktop computer, a laptop computer, a tablet device, a mobile device. The database 14 can be any suitable database for storing information such as medical imaging orders and associated study metadata. In some examples, the database can implement a SQL database. An example database 14 structure is illustrated in
The client 12 generally provides a user interface through which a user can communicate requests to the worklist broker 16, the imaging device 18, or both. For instance, a user can generate an order for medical imaging at the client 12 and this order is communicated to the database 14 for storage and sent to the worklist broker 16, from which it is later retrieved, when the imaging device 18 is used to image the patient associated with the order. To this end, the order includes study metadata input by the user at the client 12. Study metadata may include metadata information about the patient, the imaging procedure to be performed, provider information, the performing facility, and so on. The order can be a non-appointment order, such as may be generated in a point-of-care location where a clinician requests a medical imaging order at the time of evaluating a patient rather than in advance of the patient's appointment. This workflow provides an improvement over conventional ordering and scheduling workflows that require order placement through a RIS.
As shown in the example of
The images and attached order are then sent to an archive 20 that is in communication with the imaging device. The archive 20 can be a Picture Archiving and Communications System (“PACS”), a vendor neutral archive (“VNA”), a long term archive (“LTA”), or other suitable archive for storing medical images and associated metadata on a short-term or long-term basis. As shown in
In some instances, a user will acquire medical images with the imaging device 18 without having previously generated an order. In these instances, the imaging device 18 will query the worklist broker 16 and the worklist broker 16 will not find an associated order in the worklist 17 stored on the database 14. The images acquired with the imaging device 18 are thus sent to the archive 20 without study metadata being attached thereto.
The archive 20 implements an algorithm to verify the images received from the imaging device 18. The verification algorithm operates on device data contained in the DICOM header of the images received from the imaging device 18 to identify where an image study came from and to capture studies that may have been sent through without an order. At the start of the verification process, the archive 20 first alerts a study notification service 21 that a new study has arrived. In some embodiments, the study notification service 21 contains a plug-in 23 that queries the database 14 to locate a matching order with an accession number identical to the one found on the DICOM header. When a matching order is found, verification succeeds (e.g., the images are identified as containing study metadata from an imaging order), and the images are stored in the archive 20 using the study metadata data retrieved from the order by the worklist broker 16. A record of the completed study transfer is then stored in a study transfer database 25 that is in communication with the archive 20, and the order status on the client 12 is updated from “In Process” to “Complete”.
When a matching order is not found by the study notification service plug-in 23, the archive 20 accepts the images, but they are flagged and stored in a quarantined state. A record of the unverified study transfer is stored in the study transfer database 25 that is in communication with the archive 20.
The client 12 implements the order application, which queries the study transfer database 25 upon launch to find any unverified studies that originated from the set of devices configured for the current user's care team. The resulting “unverified” study list displays at the client 12 so that a user may attach an order after the image file is received.
The client 12 provides a user interface through which a user can view and analyze image study data stored on the archive 20. The user interface contains tools to create an order with patient metadata retrieved from the patient management system 22, which contains the healthcare institution's patient management records; match the order with a previously unverified study; reprocess the study transfer and verification steps at the archive 20; and successfully store the study. Alternatively, the user may cancel the study transfer and process a delete of an unverified study from the archive 20 from within the client 12. In some instances, if a user does not update or add the required study metadata to a quarantined image within a specified timeframe, the client 12 (e.g., the application at the client 12) will implement an algorithm to automatically notify member of the care team via an auto-generated message, such as an auto-generated email message.
The user interface can also contain tools to create an order with patient context data retrieved from a context management system 26 or application, which can be queried to retrieve patient context information from other clinical applications.
A viewer 24 can be in communication with the archive 20 to receive images from the archive 20 for viewing. The viewer 24 can provide an interface between the electronic medical record (“EMR”) and the archive 20.
The medical imaging workflow management system 10 described here can implement a thick client application on the client 12 and that works together with the database 14, the outbound orders interface 15, the worklist broker 16, and the archive 20 to create, manage, and store in-office imaging orders and related information. As such, the described system 10 can securely store and make accessible medical image studies in the patient's electronic medical record from DICOM-enabled imaging devices 18 located within the provider's office. In addition, the described system can display information and notifications from a connected archive 20, such as a PACS, VNA, or LTA, for unverified image studies that are stored in quarantine on that system.
Ancillary connections through an HL7 orders interface, an API/interface into the patient management system 22, the worklist broker 16, and the archive 20 study notification service 21 can facilitate the exchange of orders and study metadata needed between the described system 10, the archive 20, and the EHR.
Users can launch an application at the client 12 (e.g., the client application) to both place a new order and view any quarantined image studies from their area. Display of quarantined studies can be determined by a configurable component called “care team” in relation to the AE title of the client device the study was captured on. The connection of the system 10 to the patient management components of the EHR provides the ability to query for and select a patient, and search for and link to a pre-existing event. Selections for modality, exam description, organ, side, date and time of service, provider and facility as well as a free text comments box can combine with patient and event data to create an imaging order. The user can then publish this order to the database 14, which sends it to the worklist broker 16 for selection on an imaging device 18, or submit the order to the archive 20 for re-processing of a quarantined study with the updated metadata.
Additional views provided on the user interface of the client 12 can include a historical search for viewing and an ability to edit or cancel past image order entries stored on the database 14 that are not in a completed state.

When completed, the order is sent from the client device to a database, as indicated at step 304. As described above, the database can be a SQL database or any other suitable data base for storing study metadata, such as other relational databases. The order is then sent to the worklist broker, as indicated at step 306 and is transposed to a DICOM format, as indicated at step 308. When the patient is ready to be imaged, the imaging device with which the patient will be imaged queries a worklist broker that has received and stored an order from the database, as indicated at step 310. In some instances, the imaging device can include a user interface that provides a display showing orders queued in the worklist, such that the user can select the appropriate order for the patient being imaged. In response to the query for an order, the worklist broker retrieves the appropriate order from the worklist, as indicated at step 312, which has transposed the metadata contained therein into a DICOM format. For instance, the client application sends the order from the database to the worklist broker via an HL7 protocol, which then transposes that data into a DICOM format and stores the order to its worklist. When queried by a connected image device, the worklist broker provides the DICOM-formatted metadata to the imaging device.
Images of the patient are acquired after the order has been retrieved, and the DICOM-formatted metadata received from the worklist broker is attached to the images, as indicated at step 314. The acquired images (and the attached metadata) are then communicated to an archive for storage, as indicated at step 316. The archive may include a PACS, VNA, LTA, or other suitable archive for storing medical images and associated data on a short-term or long-term basis.
When the images and attached metadata are received by the archive, the archive implements a verification algorithm to verify the status and metadata content of the images. If the images are verified, as determined at decision block 320, they are stored in the archive, as indicated at step 322. If the images are not verified (e.g., if there is metadata missing from the images or incorrect metadata attached to the images) then the archive stores the images, but flags the images as being in a quarantined state, as indicated at step 324. As will be described below, the images stored in the quarantined state are reported to the client device to update or correct the metadata attached to or missing from the quarantined images.

When the user selects to cancel the unverified study, as determined at decision block 512, the images are deleted from the archive, as indicated at step 514. If the user decides to do nothing, the data in the unverified study is not updated. As a result, the user is notified automatically that they must reconcile or cancel, as indicated at step 516. This notification may be presented to the user immediately, or after a specified amount of time.

When completed, the order is sent from the client device to a database, as indicated at step 604. As described above, the database can be a SQL database or any other suitable data base for storing study metadata, such as other relational databases. The order can then be processed as described above.
Images of the patient are acquired before the order has been placed and are stored in a non-DICOM format in a network file location or other storage media. The non-DICOM images can be image formatted as JPG, BMP, PDF, or other digital image file types. When entering an order, a user interface is presented to the user to browse to a computer file or network file location in order to select an image, as indicated at step 606.
The selected images are then ordered into the desired sequence, as indicated at step 608. An image study manifest is then created, as indicated at step 610, and then committed to the database, as indicated at step 612. For instance, the image study manifest can be committed to the database by building the data set associated with the image study manifest and storing that data to a table in the database. An example of an image study manifest data structure is illustrated as the “ImageStudyManifest” data entry in
When the images and attached metadata are received by the archive, the archive implements a verification algorithm to verify the status and metadata content of the images. If the images are verified, as determined at decision block 620, they are stored in the archive, as indicated at step 622. If the images are not verified (e.g., if there is metadata missing from the images or incorrect metadata attached to the images) then the archive stores the images, but flags the images as being in a quarantined state, as indicated at step 624. As described above, the images stored in the quarantined state are reported to the client device to update or correct the metadata attached to or missing from the quarantined images.
