Description

The invention relates to a method for controlling the operation of a medical technology device, which comprises at least one output device used for outputting a user interface with an assigned and / or integrated input device, setting information used to control the medical technology device being determined by means of the user interface. In addition, the invention relates to a medical technology device, a computer program and an electronically readable data carrier.

Modern medical technology facilities, in particular larger medical technology systems, for examining and / or treating patients are becoming more complex in terms of their equipment and operation. The operation of a medical diagnostic / therapy system therefore presents a challenge in terms of usability and ergonomics in implementation. Simple and intuitive operation is desirable, but is often insufficiently implemented in previously known medical technology facilities. For example, medical examination devices, in particular x-ray devices, are known which have a large number of operating locations with different operating devices for the operation. For example, a screen console with keyboard and mouse can be provided in an anteroom of the room in which the medical technology device is arranged, a touch screen, for example on a ceiling-mounted X-ray emitter, and / or one or more local control units (wired) as an output and input device or wireless) can be provided.

Most of such operating devices, formed from a display device and an associated and / or integrated input device, use different types of user interfaces, predominantly graphical user interfaces (GUI). The user interacts with most of these user interfaces based on touch and / or using a mouse. Incidentally, the prior art has also already proposed using mobile operating devices as operating devices, for example smart devices.

User interfaces are programmed so that, on the one hand, they can be operated by all conceivable users, and on the other hand, all conceivable functionalities can also be controlled by the user interfaces. This results in complex operating devices for which users have to be specially trained and / or have to use help functions / operating instructions, especially when tasks that are seldom carried out are to be mastered. Although it has also been proposed in the meantime to make user interfaces adaptable by users themselves and to store these adaptations in a user profile, this simplifies the operation of the medical technology device only to a limited extent.

The invention is therefore based on the object of specifying a configuration of an operating device which simplifies the operation of a medical technology device and in particular also improves the usability of the medical technology device.

This object is achieved by a method, a medical device, a computer program and an electronically readable data carrier in accordance with the independent claims. Advantageous configurations result from the subclaims.

A method according to the invention of the type mentioned at the outset provides for the user interface to be updated using output data from at least one analysis algorithm of artificial intelligence, the input data for the analysis algorithm being determined and at least additional information describing the condition and / or the actions of the user in addition to the input activity is used.

The use of additional information about the user, which does not describe his input activity per se and is required anyway so that the operating device formed from the output device and the input device can fulfill its task, makes it possible to respond much better to the user and thus one in particular to create an adaptive and intelligent user interface based on the user state, which makes the operation of the medical technology device significantly more intuitive, thus simplified, and can support the user in a targeted manner according to his needs. In addition, it is particularly preferred if operating data describing the input activity of the user and / or the operating state of the medical technology device and / or system data describing the run state of a workflow to be carried out are also used as input data for the analysis algorithm. A comprehensive database thus exists, on the basis of which, as has been shown, it is excellently possible to implement a corresponding adaptive and intelligent user interface which provides suitable information and / or input options in the current operating situation of the medical technology device. there system data describing a workflow to be carried out can of course also describe a task currently to be carried out with the medical technology device, for example an examination task and / or a treatment task relating to a current patient.

Based on such input data, in particular system data, operating data (which ultimately represent interaction information) and the additional information in combination with artificial intelligence, useful output data can be generated which allow an excellent, current adaptation of the user interface. For example, it is possible to predict the role of the user, his skill level, any problems that may exist and the next steps that are likely to follow in the workflow. On the basis of such and other information, the intelligent and adaptive user interface can provide role, task, operating and user status-specific information and / or input options and / or help / guidance, which preferably also depends on the specific ability of the user to operate the medical technology device, can be based. Overall, the operation of the medical technology device is thus simplified and in particular also accelerated. Using the intelligent and adaptive user interface, the user can be guided to more optimal results in special task areas.

In summary, the present invention thus uses different input data, including in particular the user-related additional information, in order to provide an adaptive, intelligent user interface. The advantages are in particular that it is easier to work with an intelligent, adaptive user interface (Intelligent Adaptive User Interface - IAUI), since it can also provide role, skill level and user status based user interface elements, support and guidance due to the additional information. For example, novice users can gradually learn to operate the medical technology device and the level of support, guidance and help can be reduced while the user's ability to operate the system increases. This results in competitive advantages for manufacturers who can therefore offer medical technology devices which provide user interfaces which allow easier, faster and safer control of the medical technology device.

The additional information can be determined with particular advantage from sensor data of a sensor that detects at least part of the user. Both additional and already existing sensors can be used, which are part of the medical device or assigned to it.

In a particularly preferred embodiment of the present invention, it is provided that an optical sensor, in particular a camera, is used as the sensor to track the user's direction of view of the user interface shown. If the user interface therefore has a graphical portion (GUI), which is shown in particular using a display as an output device, it can be tracked which portion of the user interface the user is currently viewing or also over time. The optical sensor can be a two-dimensional image data or preferably a three-dimensional image data camera (2D camera or 3D camera). Such sensors for tracking the gaze direction of people have already been proposed in the prior art (“gauze recognition”), but within the scope of the present invention represent a particularly expedient implementation for determining the additional information. A correspondingly derived additional information can also be referred to as gaze direction information.

Specifically, it can be provided that a portion of the user interface determined by the user and determined on the basis of the viewing direction is used as additional information. In particular, the user's gaze can also be assigned to one or more user interface elements shown on the currently displayed user interface, for example windows, displayed information and / or operating options. This makes it possible not only to determine, for example by analyzing the time course, how long a user is looking for certain elements of the user interface or to understand them, but also to determine whether the user is missing important information about a user interface element. While the former information can be evaluated, for example with regard to a user's ability (skill level) or a feeling state of the user, the latter information, that is to say a user interface element which is not perceived but is rated as important, can indicate an existing problem.

Accordingly, a particularly advantageous development of the present invention provides that when the information is assessed as important and is overlooked on the basis of the portion considered, the analysis algorithm updates the user interface for better perception of the information and / or for reference to the information. By identifying user interface elements that have been overlooked by the user, For example, warnings that are ignored can be decided on the part of the analysis algorithm to emphasize these user interface elements, which can also go beyond graphic output, for example by acoustic warning signals together with graphic highlights or the like. In this way, the overall security of the medical technology device is increased, since a permanent oversight of important information can be avoided more reliably.

In a particularly advantageous further development of the present invention, it can be provided that, in particular in the case of an optical sensor which also detects the face of the user, an image expression of the facial expression, in particular a feeling state of the user and / or the age of the user, by image processing of sensor data of the optical sensor, descriptive additional information is determined. Based on the image data supplied by the optical sensor, which is designed in particular as a camera, an expansion can also be carried out with regard to the recognition of facial expressions, emotional states and age in order to expand the additional information accordingly and to provide further useful information for the analysis algorithm. In particular, as already fundamentally suggested in the prior art, this context can also provide that an image processing algorithm of artificial intelligence is used for image processing, which can determine such additional information in a particularly reliable and robust manner. For example, image data of the optical sensor can be processed continuously for the classification of emotional states, age, facial expressions and the like. Such additional information can be evaluated with particular advantage with regard to the ability of the current user and / or the presence of current problems. For example, a confused facial expression of a user can indicate that he is overwhelmed by the current situation and needs specific help, which can be specified even more precisely, especially when using system data as input data, based on the current task or the current execution status of a workflow. With regard to the prediction of possible future steps, information about the emotional state and / or facial expressions of the user can give clear indications which the analysis algorithm, which, of course, was also trained using suitable training data, can recognize accordingly. With regard to the detection of the age of the user, existing problems can possibly be weighted differently in terms of their probability of occurrence and / or an adjustment can be made to an estimated existing reaction speed of the user.

In the context of the present invention, it is also conceivable if a gesture sensor, which is also used to record input activities and which detects gestures of the user, is used as the sensor. In particular, this can be a capacitively measuring input sensor of a touch screen as a combined output device / input device. Corresponding sensors are now also able, for example, to detect hand and arm movements above the display area, in particular in the form of a spatial 3D capacitance sensor, from which gestures of the user can in turn be concluded. It should be noted that appropriate gestures may not only be interpreted as additional information, but may also at least partially serve as input data if the corresponding input option is provided, which may enable faster work, for example, for certain tasks, in particular image processing in image recording devices. In this context, it should also be pointed out that gesture recognition can also take place via an optical sensor, which perceives the corresponding areas of the user, in particular when using a 3D camera. In specific configurations, gestures of helplessness or the like can be classified and detected, for example, and can be sent to a corresponding evaluation by the analysis algorithm.

It has proven to be particularly expedient in the context of the present invention if an identification of a current user takes place. This makes it possible to assign additional information to a specific user, or to view a time course of additional information (and further input data) that is clearly assigned to a user, which is useful, for example, when a skill level of the user is to be determined. An identification of a user is to be understood as the detection of a user change on the operating device, since it then becomes clear that the additional data relate to another user from now on. However, it is preferred to use user profiles and / or user accounts that are created automatically and / or on the basis of user-side inputs in order to be able to assign the input data to a defined user.

The identification of the user can be based on a user input, in particular a login process, and / or on the basis of biometric data of the user, in particular by evaluating image data of the optical sensor, respectively. When logging in, for example, a user profile that is permanently provided in terms of data processing technology can be used by querying a user name and a password. However, it is particularly advantageous to automatically identify and, in particular, to recognize the user again, for which the aforementioned optical sensor, in particular the camera, which provides image data of the user's face, is particularly suitable, for example in order to carry out facial recognition using generally known algorithms.

It is also preferred, as already indicated, if a user profile is used for each identified user in which at least one user information selected from the input data and / or ascertained when the analysis algorithm is executed is stored. This does not have to be permanent storage, but it is quite conceivable to also create a user profile dynamically for a current user. However, it is preferred to permanently hold user profiles, in particular in the case of automatic recognition, for example by means of face recognition, in order to allow “recognition” of a user and to track the development of a user, in particular with regard to the ability to operate the medical technology device, over several operating cycles and also to that effect to allow adaptive and intelligent adaptation of the user interface.

A role of the user can preferably be determined using a temporal course of additional information and / or on the basis of the identification and can be used when updating the user interface, in particular by using role-specific user interfaces. While a role of a user, the roles used preferably comprising a doctor and / or technical assistant and / or medical assistant, can often already be derived from an identification of the user, it is also conceivable to assign a role to the user behavior given by the additional information conclude, in which case additional input data, in particular system data and / or input data, can preferably also be used here. If the role of the user is only known, in particular role-specific user interfaces can be generated by the corresponding update, for example a different representation or general output for a doctor, such as for a medical and / or technical assistant. Therefore, an optimal adaptation to the current user can also take place in this regard.

In a particularly preferred development, it can be provided that an analysis of the time course of at least the additional information, in particular also the operating data, determines a skill level describing the user's ability to operate the medical technology device and is used when updating the user interface. By observing the operating activity and the other behavior of the user, it is therefore possible to infer a skill level, that is to say an ability value, of the user with regard to the medical technology device. For example, beginners can be recognized as such on the basis of long searches, confused emotional states / facial expressions, frequent operating errors and the like, the level of sophistication in dealing with the operating device using the user interface being able to be recognized accordingly by increased security during the operating activity. Specifically, it can be provided, for example, that the skill level is determined in predetermined levels, in particular comprising beginners, experienced users and experts.

In this way, for example, beginners can gradually learn how to operate the medical technology device, with the support, guidance and auxiliary functions being reduced over time as the skill level of the user increases. Operator safety is increased by using user interface elements that are adapted to the skill level of the user.

In general, it can be provided in a preferred embodiment of the present invention that the analysis algorithm predicts further operating steps on the basis of the input data and the user interface is updated in order to carry out these operating steps. The use of artificial intelligence is particularly suitable for using the input data to predict which future steps are pending, which means which operator actions / input activities are to be expected next. The user interface can then be updated accordingly so that these steps can be implemented quickly and easily.

At this point, it should also be noted that, of course, the artificial intelligence analysis algorithm can also be trained during everyday operation, which in the example of predicting further operating steps can mean, for example, that an incorrect prediction is recognized and at the same time it is learned which operating steps the User instead of the actually predicted operating steps. This ability to learn can of course also be transferred to other possible applications, for example incorrectly identified roles, incorrectly identified emotional states and the like.

In the context of the present invention, it is also expedient if the analysis algorithm identifies existing problem and / or error states on the basis of the input data, in particular also system data, and if the user interface for displaying and / or eliminating the present problem and / or error states is identified by the User is customized. These problem and / or error states include, in particular, the cases of missing important information in a graphical user interface which have already been described and which can be handled accordingly. However, other problem and / or error states, which can also be described in particular by system data, can be covered by the present method, for example by adapting the user interface to the current operating state of the medical technology device, that is to say also in the case of existing technical errors / problems. to allow the error / problem to be eliminated as easily as possible.

If the user interface includes a help function, an expedient development of the present invention provides that the help function is also updated as a function of the output data. For example, a help function can be adapted to a role and / or a skill level of the user, but an adaptation of the help function to currently existing problems / errors and / or predicted operating steps and / or the current emotional state of the user is also conceivable.

The determination of the output data and / or the updating of the user interface can also be carried out in order to optimize the execution of a workflow or the workflow to be carried out. If there is a specific workflow to be carried out, for example based on a current examination and / or treatment task for a patient, its sequence can be optimized, in particular with regard to the speed of the implementation and / or the qualitative result, by the user operating activity through the user interface is directed specifically to a faster and / or high quality execution of the workflow.

A particularly expedient development of the present invention provides that the input device comprises a voice interaction device with at least one recording means for spoken user input. This means that the intelligent and adaptive user interface can also be supplemented by voice input and in particular also voice output functionality, so that preferably the voice interaction device as part of the output device also includes a voice output means, the voice output being used as part of the user interface. The result is a so-called "Natural Language UI", which expediently supplements a graphic part of the user interface.

In an embodiment which is particularly expedient in this regard, it can be provided that speech recorded by the recording means, in particular also outside of the operating activity, is analyzed by means of a speech analysis algorithm to determine additional information. The speech analysis algorithm can also be an artificial intelligence algorithm. By analyzing the language of the user, it is also possible, on the one hand, to recognize emotional states, for example insecurity and the like, as additional information, which in turn can be used to infer, for example, the skill level of the user. However, other communication in the room in which the medical technology device is located can also be analyzed, so that, for example, questions from the user to other persons present can be used to infer the role of the user and the like. With regard to a speech analysis, too, there are numerous possibilities for determining and using additional information.

The medical technology device can in particular be an image recording device, for example an X-ray device. In modern image recording devices in particular, it is becoming increasingly difficult to operate the medical technology device due to the increasing quality and quantity of the equipment and the variety of possibilities, so that an intelligent and adaptive user interface brings about a significant improvement here. However, the present invention can also be used advantageously for other medical technology devices, in particular treatment devices, with increasing complexity and, in parallel, increasing benefits.

In addition to the method, the invention also relates to a medical technology device, in particular an image recording device, comprising at least one output device used for outputting a user interface with an associated and / or integrated input device and a control device designed to carry out the method according to the invention. All statements relating to the method according to the invention can be transferred analogously to the medical technology device according to the invention, with which the advantages already mentioned can thus also be obtained. The control device can comprise at least one processor and / or at least one storage means. To implement the method according to the invention, the control device can preferably have at least one determination unit to determine the additional information or the input data in general and include an analysis unit to implement the analysis algorithm. The resulting output data can be used by an update unit to update the user interface. In addition to existing functional units, for example those that derive the setting information used to control the medical technology device from the user's input activity, other functional units can of course also be provided to implement further aspects of the present invention.

A computer program according to the invention can, for example, be loaded directly into a memory of a control device of a medical technology device and has program means to carry out the steps of a method according to the invention when the computer program is executed in the control device of the medical technology device. The computer program can be stored on an electronically readable data carrier according to the invention, which therefore includes electronically readable control information stored thereon, which comprise at least one computer program according to the invention and is designed such that when the data carrier is used in a control device of a medical technology device, it carries out a method according to the invention. The data carrier can be a non-transient data carrier, in particular a CD-ROM.

Further advantages and details of the present invention result from the exemplary embodiments described below and from the drawings. Show:

• 1 1 shows a basic sketch of a user arranged on an operating device,
• 2 2 shows a functional diagram to explain the method according to the invention,
• 3 a user in a first operating situation,
• 4 a user in a second operating situation, and
• 5 a medical device according to the invention.

1 schematically shows a user 1 on an operating device 2 , which in the present case as a touchscreen combining an output device and an input device 3 is trained. The control device 2 is part of a medical technology device, for example the console of an image system of an image recording device such as an X-ray device. Alternatively or in addition to using a touchscreen 3 A mouse can also be provided as an optional additional input device.

There is a graphic part on the touchscreen 4 a user interface with different user interface elements. Using an analysis algorithm of artificial intelligence, the user interface is now to be implemented as an intelligent and adaptive user interface, so that the medical technology device can be operated simply, quickly, intuitively and safely. This analysis algorithm uses certain input data, the sources of which are also explanatory in 1 are already shown in more detail.

Thus, the medical technology device initially comprises one as a camera 5 , in particular 3D camera, trained optical sensor 6 , the present upside down 7 of the user 1 , especially his eyes 8th and the face 9 , is directed. From the image data of the camera 5 the proportion can be determined by looking in the direction of view 10 , in particular in the form of user interface elements, at which the user's gaze 1 is directed. Furthermore, an image processing algorithm of artificial intelligence is applied to the image data of the camera 5 applied the facial expressions, emotional states and the age of the user 1 can recognize. Also an identification of the user 1 is done by facial recognition in the image data of the camera 5 ,

Such, not directly on the input activity of the user 1 related input data will be referred to below as additional information. Additional information can optionally be used in addition to an evaluation of the image data of the camera 5 also from sensor data of a capacitive, the touchscreen 3 for determining inputs assigned to sensors 11 be derived. For example, gesture recognition is conceivable here. In any case, the sensor delivers 11 operating data as input data for the analysis algorithm, as is known in principle; further sources of operating data can originate from the addressed mouse and / or other input devices.

Operating data and additional information can also be obtained from information from a further provided voice interaction device 12 determine, which in the present case comprises a recording means for spoken user input and a voice output means, the voice output also being used as part of the user interface, so that an acoustic part of the user interface ("Natural Language UI") also arises. Speech recorded with the recording means can also be evaluated by means of a speech analysis algorithm, in particular a speech analysis algorithm of artificial intelligence, to determine additional information.

Finally in 1 also a general control device 13 shown of the medical device, which can have the determination unit for the additional information or other input data, but can also supply input data itself, in particular in the form of system data that describe the operating state of the medical device and the state of execution of a workflow to be carried out. A workflow can include, for example, a measurement protocol or the like in an image recording device. Overall, it describes the intended course of an examination and / or treatment process on a patient using the medical technology device.

2 explains the sequence of the method according to the invention again in more detail. The input data are shown on the left 14 which, as described, consist of system data 15 , Operating data 16 and additional information 17 which relates to the user but does not affect the input activity (directly). The additional information, as already regarding the 1 explained, therefore relates to the state and / or the actions of the user in addition to the input activity, which is caused by the operating data 16 is described.

Of course, other input data can also be used, if appropriate 14 be used.

The input data 14 are through the analysis algorithm 18 of artificial intelligence, with a skill level of the user being present as the starting data 1 , a role of the user 1 , a feeling state of the user 1 , predicted next steps of the user 1 as well as potentially and / or actually existing errors and / or problems are determined. The resulting output data are in one step 19 used to update the user interface. User interface elements can be adapted, for example, to the skill level of the user, for example, beginners to experts, and specific user interfaces for the role of the user 1 (for example, doctor / X-ray technician / medical assistant), specific guidance and workflow optimization can take place, a help function can be adapted and specific information and / or input options can also be pointed out. This provides an adaptive and intelligent user interface.

A special case of error and / or problem states is the fact that information is overlooked by the user 1 This is due to the in 3 and 4 indicated operating states explained in more detail. In the operating situation of the 3 is used as a user interface element 20 an information rated as important, for example a warning, is output. The direction of view detection shows that the portion perceived by the user 10 with the UI element 20 overlaps the user 1 thus perceives the information presented. In this case there is obviously no problem.

This is different in the in 4 shown operating situation. There is based on the share 10 to recognize that the user 1 not paying attention to the user interface element 20 and has not aimed at it during the period of its display (which can be deduced from the course of the user information). The user interface element 20 was overlooked. This can be a problem with important information.

However, the adaptive and intelligent user interface can now react to this by clicking on the user interface element 20 is more clearly pointed out, for example, this is flashing and / or displayed in a signal color, and / or the user interface element 20 in the share 10 is moved and / or an additional indication of the user interface element 20 he follows. This is only a useful, concrete example of the customization options of the user interface that can be achieved through the described procedure.

4 finally shows a schematic diagram of a medical technology device according to the invention 21 , The medical technology facility 21 is designed as an X-ray device, which is a ceiling-mounted X-ray unit 22 with an x-ray tube 23 as well as a patient couch 24 has an associated X-ray detector 25 can be arranged.

There are two controls 2 the medical technology facility 21 shown, namely on the one hand a workplace operating device assigned to the image system 2 with a monitor 26 as an output device and a keyboard 27 as well as a mouse 28 as input devices. The further control device 2 includes a touch screen 3 on the X-ray unit 22 ,

The X-ray facility 13 is now for both controls 2 trained to implement the method according to the invention, consequently to apply the analysis algorithm of artificial intelligence to input data comprising additional information in order to obtain output data by means of which the adaptive and intelligent respective user interface can be updated.

The control device can do this 13 in particular have a determination unit for the additional information and further input data, an analysis unit for carrying out the analysis algorithm and an update unit for the corresponding update of the user interface. Other functional units, especially those that control the input activity of the user 1 in setting information for the medical device 21 convert, of course, can also be provided.

Although the invention has been illustrated and described in detail by the preferred exemplary embodiment, the invention is not restricted by the disclosed examples and other variations can be derived therefrom by a person skilled in the art without departing from the scope of protection of the invention.
