Description

FIELD OF THE INVENTION

The invention relates generally to the field of medical imaging, and in particular to controlling medical imaging systems. More specifically, the invention relates to a controller for a medical imaging system.

BACKGROUND OF THE INVENTION

Digital medical images can be captured/obtained using a variety of medical imaging systems, for example, using a computed tomography (CT) system, computed radiography (CR) system, or a digital radiography (DR) system. In addition, conventional x-ray can be converted into a digital medical image using a digitizer.

The medical community relies heavily on medical imaging systems for storage and display of these digital medical images. A workstation/computer is an example of a medical imaging system. One particular example is a RIS (radiology information system) workstation which can be used to store, manipulate, and retrieve information for planning, organizing, directing, and controlling administrative activities associated with the provision and utilization of radiology services and facilities. Another particular example is a PACS (picture archive and communication system) workstation which used for picture viewing, image tracking, archiving, retrieval, and communications. Images from multiple medical imaging systems can be directed between diagnostic viewing stations and archive servers. An example of a PACS system is the Kodak MiniPACS for Mammography System which is a high volume diagnostic workstation for use in storing, retrieving, distributing, and presenting patient study data and images.

Control means are available for controlling the operation of such medical imaging systems. However, there exists a need for a user-friendly controller that provides for flexible, efficient, and easy use of medical imaging systems.

The present invention provides a controller for a medical imaging system which is user-friendly and provides flexibility in method of use.

DETAILED DESCRIPTION OF THE INVENTION

The following is a detailed description of the preferred embodiments of the invention, reference being made to the drawings in which the same reference numerals identify the same elements of structure in each of the several figures.

Referring to FIG. 1, a controller 10 in accordance with the present invention is used to control a medical imaging system 12. Medical imaging system 12 can be connected to a network for communication 13 with other devices, for example, an archive storage device 14, one or more modalities 16, and one or more databases 18, and one or more workstations 19 where images can be viewed.

Controller 10, in accordance with the present invention, is more particularly illustrated in FIGS. 2 and 3. Controller 10 includes a hand-held unit 20 and a base unit 22. Hand-held unit 20 has a first shape, as best shown in FIG. 2, which provides for handling by a user with one hand. Hand-held unit 20 includes at least one user control member 30 for controlling medical imaging system 12. These user control members will be more particularly described below. The user/operator can effect operation of medical imaging system 12 using the user control members of hand-held unit 20.

Base unit 22 has a cavity 24 adapted to receive hand-held unit 20. Cavity 24 is configured to have a second shape that complements the first shape of hand-held unit 20. As such, when hand-held unit 20 is received within cavity 24 of base unit 22, a substantially continuous surface is formed.

Base unit 20 also includes at least one user control member 32 for controlling medical imaging system 12. These user control members can be operated by a user when hand-held unit 20 is not received within cavity 24. Likewise, the user control members of hand-held unit 20 can be operated by a user when hand-held unit is not received within cavity 24. When hand-held unit 20 is received within cavity 24, controller 10 can be operated by one hand of a user. That is, the user control members on both hand-held unit 20 and base unit 22 can be operated by a hand of a user.

Hand-held unit 20 may require the use of batteries for operation. Therefore, it may be desirable for base unit 22 to include an electrical connector 25 disposed within cavity 24 which can be used to recharge the batteries disposed within hand-held unit 20. Hand-held unit 20 would include a matable connector such that, when hand-held 20 is received within cavity 24, the hand-held unit's connector would mated with the base unit's electrical connector to effect charging of a battery disposed within the hand-held unit.

Control members 30,32 can include a corresponding label/text adjacent/proximate the particular user control member so as to assist the user in operation of controller 10. For example, referring to FIG. 3, a label 40 of “NEXT” is shown on control member 42 configured as a button pressable/clickable by a user. This “NEXT” button can be intended to control the display of the next stage. More particularly, a user control member for next stage could display the next stage of the currently applied display protocol. For example, for mammography, each stage is typically a separate viewbox. The stage can include one, two, four, or eight images.

Similarly, referring to FIG. 3, a label 41 of “PREV” is shown on control member 44 configured as a button actuatable by a user. This “PREV” button can be intended to control the previous stage of the currently applied display protocol. Again, each stage is typically a separate viewbox.

A control member can be configured as a trackball 46 for scrolling and selecting options displayed on a display of the medical imaging system.

FIG. 4 shows a block diagram illustrating exemplary operations of the medical imaging system that can be controlled using user control members 30,32 of the controller of the present invention.

A user control member for “read” could mark the current study as “read” and load the next study into a worklist.

A user control member for “full screen” could toggle the system in/out of full screen mode. When in the full screen mode, an image is displayed using a full resolution of the display monitor. When the user logs in, the default state for the system could be the full screen mode.

A user control member for “next patient” could access the digital medical images for a next patient.

A user control member for “Window/level presets” could actuate presettings. For example, a first preset could apply a first window/level preset to the displayed image “underneath” the cursor. A second preset could apply a second window/level preset to the image underneath the cursor. Similarly, an automatic preset could apply an automatic window/level preset to the image underneath the cursor.

A user control member for “logout” could terminate the application/session and log the user off the system and close down the application.

A user control member for “Reapply display protocol” could display the medical images in their original order and arrangement.

A user control member for “print” could cause the printing of the currently displayed image.

A user control member for “Full screen” could remove all menus and toolbars, displaying only the medical image.

A user control member for “Barcode reader” could cause the activation of a bar code reader in communication with the medical imaging system. Upon activation, information from the bar code would be read. The bar code reader could be integral to hand-held unit 20 or separate form hand-held unit 20.

A user control member for “speaker” could cause the activation of a speaker. Similarly, a user control member for “microphone” could cause the activation of a microphone, and consequently, record information. If such a function is provided, additional dictation functions of record/play/stop/pause may be desired.

A user control member for “Window/level”, “Pan”, “Zoom”, and “magnify” (or “magnification”) can also be available.

The user control member for “Window/level” could control a selected state and a de-selected state/mode. That is, actuating this control member could place the system in a selected state and actuating the control member again would place the system in a de-selected state. Selection of this control member can place a trackball and the system in a window/level mode. If the pan, zoom, or magnify mode has been previously selected (using a user control member), that mode could be automatically de-selected. A pointer/cursor on the medical imaging system could change to the window/level mode if it is not already. When in window/level mode, manipulation of the trackball could adjust the window and level responsive to the direction/motion of the trackball movement. De-selection of the window/level mode can take the system out of window/level mode.

The user control member for “zoom” can control a selected state and a de-selected state/mode. That is, actuating this control member could place the system in a selected state and actuating the control member again would place the system in a de-selected state. Selection of this control member can place a trackball and the system in a zoom mode. If the pan, window/level, or magnify mode has been previously selected (using a user control member), that mode could be automatically de-selected. A pointer/cursor on the medical imaging system could change to the zoom mode if it is not already. When in zoom mode, manipulation of the trackball could enlarge or reduce (in size) the displayed image responsive to the direction of the trackball movement. For example, if the trackball motion is in a first direction (for example, upward), the displayed image could be enlarged. Similarly, if the trackball motion is in a second direction (opposite the first direction, for example, downward), the displayed image could be reduced in size. De-selection of the zoom mode can take the system out of zoom mode.

The user control member for “magnify” could control a selected state and a de-selected state/mode. That is, actuating this control member could place the system in a selected state and actuating the control member again would place the system in a de-selected state. Selection of this control member can place a trackball and the system in a magnify/magnification mode and display a region of interest view box. If the pan, zoom, or window/level mode has been previously selected (using a user control member), that mode could be automatically de-selected. A pointer/cursor on the medical imaging system could change to the magnify mode if it is not already. When in magnify mode, manipulation of the trackball could move the region of interest view box in a direction responsive to the direction/motion of the trackball movement. De-selection of the magnify mode can take the system out of magnify mode.

The user control member for “pan” could control a selected state and a de-selected state/mode. That is, actuating this control member could place the system in a selected state and actuating the control member again would place the system in a de-selected state. Selection of this control member can place a trackball and the system in a pan mode. If the magnify, zoom, or window/level mode has been previously selected (using a user control member), that mode could be automatically de-selected. A pointer/cursor on the medical imaging system could change to the pan mode if it is not already. When in pan mode, manipulation of the trackball could cause panning of the displayed image in a direction responsive to the direction/motion of the trackball movement. De-selection of the pan mode can take the system out of pan mode.

A user control member for “exit” could initiate a procedure to exit/end the particular application. If a study is displayed, the user can be prompted to indicate whether or not they wish to confirm the current study.

A user control member for “CAD” could actuate/de-actuate the display of CAD (computer aided detection) markers on the displayed image.

A user control member for “Worklist” could display the worklist without unloading or changing the mode of the current study.

A user control member for “unload all” could unload all the studies with any change in study mode and display the worklist.

User control members can also be positioned on a back-side of hand-held unit 20. As such, when the user is holding hand-held unit, such a user control member can be activated by the user's hand. However, when hand-held unit 20 is received within base unit 22, such a back-side positioned control member would not be accessible. If such a control member is desired for operation when unit 20 is received within unit 22, the particular control member can be made available on base unit 22.

For example, referring to FIGS. 5 and 6, a “NEXT” and “PREV” control member(s) 50 may be positioned on a back-side 52 (i.e., a side adapted to be disposed within cavity 24) of hand-held unit 20. Control members for “NEXT” and “PREV” can also be positioned on base unit 22, as shown in FIG. 3 as elements 42 and 44, respectively. With such an arrangement, member 50 is not accessible when hand-held unit 20 is mated with base unit 22, however, members 42, 44 are accessible when hand-held unit 20 is mated with base unit 22. Accordingly, some operations of hand-held unit 20 and base unit 22 can overlap. However, when mated, preferably all functionality is provided, and each operable user control member provides a separate/different operation.

It may be desirable, from an ergonomics stand point, to position the user control members in a particular location and/or order on hand-held unit 20 and/or base unit 22. For example, user control members which are often typically used, might be positioned in a location readily accessible for activation by the user, whereas a user control member which is not typically often used might be positioned in a more remote location of the hand-held unit and/or base unit.

It may also be desirable to group the user control members in some particular manner. For example, hand-held unit 20 might include user control members directed to manipulating the display of an image whereas base unit 22 might include user control members directed to administrative functions of the medical imaging system.

Accordingly, preferably, hand-held unit 20 includes a first set of user control members for effecting a first set of operations of the medical imaging system and base unit 22 includes a second set of user control members for effecting a second set of operations of the medical imaging system.

In a preferred embodiment, the first set of user control members controls the manipulation of an image displayed on a display of the medical imaging system (for example, zoom, pan, magnify) while the second set of user control members controls database and administration information (for example, print, logout, reapply display protocol).

So as to reduce the number of user control members on each unit, it is preferred that the first set of user controls differs from the second set of user controls when the hand-held unit is received within the cavity. As such, each user control member available for operation by the user provides a unique control function. This can be accomplished by the position of the control member on the unit. For example, the “NEXT” and “PREV” control members, may be positioned on the back-side of hand-held unit 20. These control members can also be positioned on base unit 22, as shown in FIG. 3, such that they are accessible when hand-held unit 20 is mated with base unit 22. Accordingly, when hand-held unit 20 is received within base unit 22, only one set (i.e. the base unit set) of the “NEXT” and “PREV” control members is available for operation by the user.

Controller 10 can be physically or non-physically associated with the medical imaging system. For example, it may be desired to tether base unit 22 to the medical imaging system so as to not misplace the base unit. Alternatively, controller 10 can be wirelessly associated with the medical imaging system using wireless communication means known to those skilled in the art.

Hand-held unit 20 can be configured to transmit information to the medical imaging system through base unit 22 to effect the first set of operations, or alternatively, hand-held unit 20 can be configured to transmit information directly to the medical imaging system.

While FIGS. 2 and 3 provide one look as to the shape of controller 10, other suitable shapes can be employed. For example, FIG. 7 illustrates base unit 22 of controller 10 having a more rounded shape as compared to the shape of FIGS. 2 and 3. FIG. 8 shows a further suitable shape. FIG. 9 provides yet a further embodiment.

The invention has been described in detail with particular reference to a presently preferred embodiment, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention. The presently disclosed embodiments are therefore considered in all respects to be illustrative and not restrictive. The scope of the invention is indicated by the appended claims, and all changes that come within the meaning and range of equivalents thereof are intended to be embraced therein.
