Description

[0001] The invention relates to a method for operating a medical device with a gantry and a system for operating a medical device with a gantry.

[0002] To operate a medical device with a gantry, in particular a medical device for irradiating a patient with ionizing radiation, it is known to provide certain operating units in an examination room in which the gantry of the medical device is installed, and to provide a control unit for further operating functions in a control room outside the examination room. In particular, to protect the operating personnel, a partition wall, for example to shield against ionizing radiation, can be provided between the examination room and the control room. Visual contact with the medical device and the patient can be achieved via a window provided in the partition wall or by video surveillance. As a rule, the workflow for operating the medical device shows a clear separation between operation in the examination room and operation in the control room.

[0003] The prior art in this regard includes US 2014 / 0 037 049 A1, DE 10 2007 017 794 B3, US 2012 / 0 163 544 A1, US 2011 / 0 317 816 A1, US 2014 / 0 292 777 A1 and EP 2 468 189 A1.

[0004] Examples of steps that can take place in the examination room include bringing the patient to the medical device, preparing and positioning the patient, and discharging the patient from the examination. When positioning the patient, an examination area can be selected, for example, by moving a transfer plate on which the patient is positioned and a laser positioning aid, for example, located on the gantry.

[0005] Examples of steps that can take place in the control room are registering the patient, selecting a suitable examination protocol, performing an acquisition including follow-up and documentation on the control unit, reconstructing images, and performing quality control.

[0006] Operating the medical device may require frequent switching between the examination room and the control room. For example, a patient may be discharged after quality control of the examination results, e.g., the acquired images, has been performed. Furthermore, a new patient may be registered after the previous patient has been discharged.

[0007] The invention aims to simplify the operation of the device.

[0008] This object is achieved by a method according to claim 1 and by a system according to claim 8. Further advantageous features of the invention are contained in the subclaims.

[0009] The inventive solution to the problem is described below with reference to the claimed method and with reference to the claimed system. Features, advantages, or alternative embodiments mentioned herein are transferable to both the claimed method and the claimed system. In other words, the subject claims (which, for example, are directed to a system) can also be developed with the features described or claimed in connection with a method. The corresponding functional features of the method are implemented by corresponding subject modules.

[0010] In particular, the invention relates to a method for operating a medical device with a gantry, comprising the following steps: - Displaying a graphical user interface for operating the medical device in a first output unit of a first touch-sensitive screen, - Entering operating information using the graphical user interface through the first input unit of the first touch-sensitive screen, - wherein the first touch-sensitive screen is arranged on the gantry and / or near the gantry.

[0011] According to the invention, the graphical user interface is suitable for enabling operation of the medical device. In particular, the graphical user interface enables one or more of the following operating steps: patient registration, selection of the examination protocol, e.g., a scan protocol, patient positioning, creation of a topogram, diagnostic examination, quality control, image reconstruction, display of diagnostic images, standard image operations such as zooming / panning, scrolling through images, filtering (windowing), simple measurements, assessment and selection of automated image processing results, selection and documentation of the results on film, paper, and other media, and similar operating steps.

[0012] According to the invention, the method comprises the following steps: - Displaying the graphical user interface in a second output unit, - Entering operating information using the graphical user interface through a second input unit, - the medical device is designed to irradiate a patient with ionising radiation, - wherein the second output unit and the second input unit are arranged in a region facing away from the medical device with respect to a partition wall for shielding the ionizing radiation.

[0013] According to the invention, the area facing away from the medical device with respect to the partition wall is protected from ionizing radiation by the partition wall. The partition wall can be permanently installed in an examination room and / or between the examination room and a control room. However, the partition wall can also be movable, e.g. shiftable, foldable or freely movable (portable, shiftable, rollable or similar). In particular, the partition wall can also be fixedly or movably attached to the medical device. Furthermore, one or more partition walls with one or more windows can be provided. This allows several people to observe the device simultaneously and, if necessary, from different directions. According to the invention, the partition wall is suitable for shielding, attenuating or absorbing ionizing radiation.This is achieved by selecting appropriate building materials and wall thicknesses depending on the type and dose of ionizing radiation to be shielded. The partition wall can be made transparent in its entirety or in sections. This can be achieved, for example, using lead glass.

[0014] In the following, the first touch panel is the first touch-sensitive screen. According to the invention, operation of the medical device is possible by means of the first touch panel arranged on the gantry and / or in the vicinity of the gantry. According to a further aspect of the invention, the medical device can be operated entirely by means of the first touch panel. Furthermore, one or more first touch panels can be provided, in particular arranged on the left and / or right, at the front and / or rear of the gantry or in the vicinity of the gantry. To improve accessibility, the first touch panel can be arranged on the gantry, for example, by means of a cantilever arm that can be pivoted relative to the gantry. In particular, the first touch panel is designed to control a complete patient examination, in particular an acquisition including follow-up processing.In particular, a complete acquisition, including quality control, 3D image reconstruction, and documentation, e.g., in the form of films, can be controlled using appropriate touch gestures, without additional input devices, using only the first touch panel.

[0015] The invention thus allows for a very space-saving installation of the medical device and correspondingly simple, structured, and intuitive operation. In particular, the medical device can largely be operated by an operator located near the patient.

[0016] According to a further aspect of the invention, assistance for the operator and / or the patient can be provided via suitable displays on the first touch panel. The assistance can include, in particular, positioning options, usable positioning aids and their handling, the use and diagrams of ECG electrodes on the patient, etc. The assistance can be provided, in particular, via image and / or sound. In particular, the assistance can be provided depending on a selected examination protocol and / or on an interaction of the patient and / or the operator with the graphical user interface.

[0017] According to a preferred aspect of the invention, the second input unit is touch-sensitive, wherein the second input unit and the second output unit together form a second touch-sensitive screen. In the following, the second touch panel is the second touch-sensitive screen. Without limiting the general inventive concept, features of the second output unit and the second input unit are described below using the example of the second touch panel. Corresponding considerations apply to the case in which the second output unit and the second input unit do not form a touch-sensitive screen. For example, the second output unit can be a monitor and the second input unit a keyboard and / or a mouse. The monitor and the keyboard and / or mouse can be connected, for example, to a control unit of the medical device.

[0018] The examination of an examination area, e.g. an organ, of the patient can be initiated on the first touch panel or on the second touch panel, which is arranged in an area facing away from the medical device with respect to the partition wall. In particular, when triggering on the first touch panel, a time delay can be provided to locate an area shielded from ionizing radiation. According to a further aspect of the invention, the second touch panel is arranged in an area that is shielded by the partition wall from ionizing radiation emitted by the medical device. According to the invention, operation of the medical device is possible using the second touch panel. According to a further aspect of the invention, the medical device can be operated entirely using the second touch panel.

[0019] In particular, the examination can be followed on the second touch panel and, if necessary, interventions can be made in the examination. In particular, acquisitions including observation of a scanning process (scan) as well as complex contrast medium examinations, e.g. with contrast medium threshold triggering, can be carried out on the second touch panel. In particular, a topogram can be observed during its creation on the second touch panel and, if necessary, can be manually aborted once the coverage of the organ and / or examination area is achieved. In particular, image reconstruction can be carried out in real time with the second touch panel for visual tracking of the scan process. In particular, during contrast medium examinations, the flow of the contrast medium and sufficient coverage of the examination area can be monitored and, if necessary, interventions can be made in the examination.

[0020] According to a preferred aspect of the invention, the method comprises executing actions set by means of the graphical user interface by means of one or more control buttons.

[0021] In particular, the control buttons can be implemented as hardware. Optionally, control buttons are provided for starting, stopping, and / or interrupting the examination, in particular an X-ray scan, for executing further actions set on the first and / or second touch panel, for manual table control, or similar.

[0022] According to a preferred aspect of the invention, the method comprises a user-dependent and / or examination-dependent configuration of at least one element selected from the group consisting of the first touch-sensitive screen, the second output unit, the second input unit and the graphical user interface.

[0023] A key component of operation using the first and / or second touch panel is comprehensive, web- or network-based configuration software, which can be used on a configuration unit. This configuration reduces the actual acquisition software on the first and / or second touch panel to standard procedures and allows easy operation using touch gestures. In particular, the configuration of examination protocols, reconstruction templates, automatic image data processing, documentation, film layout assignment, sorting mechanisms, directory and folder structures, parameter adjustment, autotransfers, DICOM nodes, dispatch rules, and more can be configured.

[0024] In particular, the graphical user interface can be clearly structured through configuration. Furthermore, as many processes as possible can be pre-configured during configuration, so that operation on the first and / or second touch panel is essentially reduced to simple operating steps and options. In the case of image reconstructions, as many image reconstructions as possible can be automated and any necessary adjustments can be made using algorithms or clinic- or practice-specific definitions. If manual intervention by the user is necessary, the interventions can be carried out using simple touch gestures, e.g. rotating, sliding, dragging a graphic and selecting the options offered. Optionally, topographical and / or technical patient data can be entered and / or corrected during configuration. New patients can be registered via a web interface during configuration, e.g. if no information system such asRIS or KIS is available.

[0025] According to a further aspect of the invention, the method comprises providing a patient list and further parameters via a web interface and corresponding software such that the patient list and the further parameters can be accessed using a stationary, portable or tablet computer and / or another suitable mobile and authorized device. In this way, when the patient arrives in the examination room, the current patient can already be registered on the medical device for the examination and as many preparations as possible, such as selection of the examination protocol, can already have been made. With this registration, behavioral instructions for the patient and the operator can be provided, e.g. via the first touch panel, as soon as the patient arrives at the medical device in accordance with the selected examination protocol.The invention thus enables a simplified and time-shortened workflow.

[0026] According to the invention, the method comprises selecting and / or displaying an active or passive operating state of the first and / or the second input unit by means of the graphical user interface, wherein the active and the passive operating state differ with regard to the operating information that can be input.

[0027] According to a further aspect of the invention, the graphical user interface can be displayed simultaneously in the first output unit and in the second output unit. The operation of the first touch panel and the second touch panel can be carried out in particular depending on the needs of the patient and / or the operator and / or depending on the requirements of the examination. When the touch panel actively accesses the graphical user interface, the corresponding input unit is in the active operating state. When the touch panel actively accesses the medical device by entering operating information via the input unit, which is in the active operating state. When the touch panel passively accesses the medical device by entering operating information via the input unit, which is in the passive operating state.Optionally, the interactions performed on the touch panel with active access can be displayed on the graphical user interface on the touch panel with passive access.

[0028] According to a further aspect of the invention, the graphical user interface allows the operating state of the first input unit to be changed by means of an input at the first and / or second input unit. According to a further aspect of the invention, the graphical user interface allows the operating state of the second input unit to be changed by means of an input at the first and / or second input unit. In particular, this allows active access to the respective touch panel to be requested and / or granted.

[0029] According to the invention, the method enables different, simultaneously operating operators to recognize which touch panel has active access to the graphical user interface. For this purpose, a traffic light-like access signaling system is proposed (e.g., green = active operating state, in particular active access to the graphical user interface, yellow = passive operating state, in particular no active access to the graphical user interface), which clearly signals at all times which touch panel has active access and which touch panel only passively displays the interactions.

[0030] According to a further aspect of the invention, the graphical user interface at least temporarily has a signal button (toggle button), which, for example, signals by means of a color whether the operating state of the input unit is active or passive. In particular, active access can be transferred from the first touch panel to the second touch panel and / or the control unit in the control room at any time using the signal button (give-up access control). In particular, active access can be requested at the respective touch panel by a touch gesture operating the signal button (active get access control).

[0031] According to a further aspect of the invention, the interactions, e.g., moving graphic elements, positioning lines, etc., of the active input unit can be displayed in the graphical user interface, in particular on the output unit assigned to the passive input unit. This mirroring of the graphical user interface of the active operating state into the graphical user interface of the passive operating state enables the operation of the medical device to be taken over on the other touch panel at a suitable time, e.g., by another operator. Furthermore, the invention enables the situation on the other touch panel to be assessed before and after taking over active access and to be corrected if necessary.

[0032] The described method of access transfer and mirroring of graphical activities particularly enables remote scanning. If topogram planning is performed graphically, with the gantry close to the first touch panel and based on a real patient image or an artificial planning image (avatar), all necessary information is available by transferring control to a remotely located control unit and / or the second touch panel, for example, allowing the patient positioning and the completed or yet-to-be-executed planning of an examination to be professionally reviewed, adjusted if necessary, and performed remotely before the actual procedure.

[0033] According to a preferred aspect of the invention, the method comprises integrating image information based on the contour and / or position of a patient into the graphical user interface.

[0034] According to a preferred aspect of the invention, the method comprises selecting and / or displaying an examination region relative to a patient by means of the graphical user interface.

[0035] Patient positioning can be performed, for example, using a light sight, in particular a laser-based light sight, with a patient support device of the medical device being manually controlled. Positioning planning can also be performed using real patient images of the patient lying on the patient support device. In particular, positioning lines can be entered and displayed on the first and / or second touch panel. In particular, the invention allows a visual verification of the positioning results on the first touch panel on and / or near the gantry.

[0036] According to a further aspect of the invention, a 2D and / or 3D image of the patient is captured by means of a camera. This image is used as the planning basis for automatic patient positioning. By capturing a 3D image of the patient lying on the patient support device and automatically evaluating the contour and position of the patient, it is possible in particular to determine the vertical height of a transfer plate for supporting the patient for positioning the examination area, e.g. in an isocenter of the medical device. The acquisition of a planned topogram (overview image) can be triggered, for example, on the first touch panel on the gantry and with a set time delay for leaving the radiation-active area. The patient positioning orTopogram planning (start scan, length scan, direction) can be displayed and / or modified on a real patient image.

[0037] According to a preferred aspect of the invention, the method comprises processing and / or displaying image data recorded with the medical device by means of the graphical user interface.

[0038] In this way, for example, after the examination has been performed and before the patient leaves the medical device, the image results can be automatically checked by algorithms for sufficient contrast agent flow, area coverage according to the examination protocol and / or motion artifacts. Alternatively or additionally, the image results can be checked for quality by means of a manual viewing on a display module (viewer) integrated into the graphical user interface and / or by means of a selection of different display methods, e.g. a maximum intensity projection with bone suppression for contrast agent flow. In particular, the graphical user interface for editing and / or displaying image data acquired with the medical device can have, e.g. an integrated display module for displaying reconstructed individual images and / or image series generated via algorithms.In particular, scrolling through series, zoom / pan, windowing, measurement operations, especially for distance, angle and ROI evaluation, etc. can be realized via touch gestures.

[0039] Reconstructed images and / or image series or individual images generated by algorithms can be displayed on the touch panel in various virtual film sheets, either automatically or after manual selection, layouts can be selected, and the images can be printed. In particular, special algorithms that optimally configure the selected layout with intelligent arrangement allow operation, especially on small touch panels (e.g., ten-inch touch panels), simple, efficient, and with minimal interaction effort.

[0040] Reconstructed images and / or image series or individual images generated by algorithms can be selected automatically after creation or by touch gestures and sent, for example, to DICOM nodes. In particular, the examination can be completed and a subsequent examination initiated at the first touch panel on the gantry.

[0041] Furthermore, the invention relates to a system for operating a medical device with a gantry, comprising - a first touch-sensitive screen arranged on the gantry and / or near the gantry, - wherein the first touch-sensitive screen has a first output unit for displaying a graphical user interface for operating the medical device, - wherein the first touch-sensitive screen has a touch-sensitive first input unit for entering operating information by means of the graphical user interface.

[0042] According to the invention, the gantry forms a supporting structure of the medical device. In particular, the gantry is suitable for absorbing forces and moments acting on the medical device and transmitting them to a supporting structure. The supporting structure can, for example, be a floor, in particular a floor plate, a wall or a ceiling of the examination room. In particular, the gantry can spatially encompass an image acquisition area and / or therapy area in which a part of the patient to be imaged and / or treated is positioned for an examination. For example, a tunnel-shaped opening in the gantry can form an image acquisition area and / or therapy area. The first touch panel is arranged near the gantry when the first touch panel and a patient positioned for examination with the medical device are simultaneously within reach of an operator.

[0043] According to the invention, the medical device is designed for irradiating a patient with ionizing radiation, wherein the system has a partition wall for shielding the ionizing radiation, wherein a second output unit for displaying the graphical user interface and a second input unit for entering operating information by means of the graphical user interface are arranged in an area facing away from the medical device with respect to the partition wall.

[0044] According to a preferred aspect of the invention, the second input unit is touch-sensitive, wherein the second input unit and the second output unit together form a second touch-sensitive screen.

[0045] According to a preferred aspect of the invention, the system comprises one or more control buttons for executing actions set by means of the graphical user interface.

[0046] According to a preferred aspect of the invention, the system comprises a control unit for operating the medical device. The control unit can be arranged in a control room outside the examination room, in particular in an area shielded from ionizing radiation.

[0047] According to a preferred aspect of the invention, the control output unit is configured to display the graphical user interface, and the control input unit is configured to input operating information using the graphical user interface. According to a further aspect of the invention, the control input unit is formed by the second input unit and / or the control output unit is formed by the second screen.

[0048] According to the invention, the control unit is suitable for enabling operation of the medical device, in particular independently of the first and second touch panels. According to a further aspect of the invention, operation of the medical device is possible on the first and / or second touch panel, independent of the control unit. This independence of the first touch panel, the second touch panel, and the control unit enables highly individual adaptation of operation to the needs of the operator and / or the patient and / or to the requirements of the examination. The invention further enables the optimization of the respective working methods of the operator or multiple operators in a system comprising multiple touch-sensitive screens, input units, and / or output units.

[0049] According to a preferred aspect of the invention, the system comprises a configuration unit for user-dependent and / or examination-dependent configuration of at least one element selected from the group consisting of the first touch-sensitive screen, the second output unit, the second input unit and the graphical user interface.

[0050] According to a further aspect of the invention, the configuration unit is connected to the first and second screens, the first and second input units, and the graphical user interface, each at least temporarily for configuration purposes. This connection can be fixed and / or wireless. In particular, the configuration unit and the first touch panel and / or the second touch panel can be connected to a data transmission network, e.g., the web. In particular, any computer authorized in the network can form the configuration unit.

[0051] According to the invention, the first and / or the second input unit can each assume an active operating state and a passive operating state, wherein the active and the passive operating state differ with regard to the operating information that can be input, wherein the graphical user interface at least temporarily has means for selecting and / or displaying the operating state of the first and / or the second input unit.

[0052] The invention particularly enables the workflow to be divided into three key steps and carried out in a coordinated manner across three people and stations. Operator A can interview the patient in a waiting room and upload the patient data and examination protocol into the system via remote access. Operator B positions the patient on the medical device, plans the topogram using graphical interaction on the first touch panel, in particular the start, length and direction of the scan, positions the patient using automatic positioning or manually, and signals operator C to the control unit, e.g. by transferring active access, that the patient is ready for the examination. Operator C sees an image of the patient with positioning lines and current position in the graphical user interface, can correct the planning, readjust the patient's positioning in the gantry if necessary, and carry out the examination.After a quality check of the diagnostic images, the graphical user interface can be switched to post-processing, and the first touch panel on the gantry can be released for the next patient by transferring access. Person 3 completes the examination on the current patient, while the cycle can begin again with Person 1 in the waiting room and the next patient.
