Description

[0001] The present invention relates to a method for establishing compatibility between a patient table and a medical imaging system. The invention further relates to a compatibility system configured to execute the method. The invention also relates to a computer program and a computer-readable storage medium.

[0002] To position a patient during a medical examination or image acquisition with a medical imaging system, the patient is placed on a patient table. The patient table is typically designed to interact with the medical imaging system and support its functions. Therefore, it is essential that the functions supported by the patient table correspond to or complement those supported by the medical imaging system. The medical imaging system is designed to acquire medical image data of the patient during the examination.

[0003] For example, a function of the patient table may define a maximum travel distance along which the patient can be moved on the table. The medical imaging system may also define a maximum travel distance, which it supports, particularly through its mechanical design. These two maximum travel distances must be compatible to ensure, firstly, that the stability of the medical imaging system and the patient table is maintained throughout the entire examination, and secondly, that the examination can be performed as intended and the patient can be moved into the appropriate positions on the table.

[0004] The medical imaging system could, for example, be a magnetic resonance imaging (MRI) system. The patient table could then have a number of slots for local coils. The number of local coils can then be read by the MRI system. In this example, the number and, in particular, the positions of the slots on the patient table must match the number and, in particular, the positions of the local coils that can be read by the MRI system.

[0005] Many other functions for which the medical imaging system and the patient table must be compatible are known.

[0006] It is known that a patient table is specifically designed for use with a particular medical imaging system. The patient table thus supports precisely those functions supported by the medical imaging system. If a patient table is connected to a medical imaging system with which it is incompatible, it is known to actively prevent the use of the patient table in combination with that medical imaging system.

[0007] In a medical facility, such as a hospital or radiology practice, more than one medical imaging system is typically in use. For reasons of time and cost efficiency, it would therefore be desirable for a patient table to be compatible with or usable with various medical imaging systems. Furthermore, it is known that a patient must be examined with more than one medical imaging system for certain examinations. To avoid transferring the patient to different tables, it is also desirable for a single patient table to be compatible with multiple medical imaging systems. This saves time and allows for better comparability of the medical image data acquired with the different systems, as the patient is positioned almost identically in each image.

[0008] It is therefore the object of the present invention to provide a method that enables flexible use of a patient table with different medical imaging systems or the use of different patient tables with one medical imaging system.

[0009] The problem is solved by a method for establishing compatibility between a patient table and a medical imaging system, by a compatibility system for establishing compatibility between a patient table and a medical imaging system, by a computer program product, and by a computer-readable storage medium according to the independent claims. Advantageous embodiments are listed in the dependent claims and in the following description.

[0010] The inventive solution to the problem is described below with regard to both the claimed devices and the claimed method. Features, advantages, or alternative embodiments mentioned herein are also applicable to the other claimed items and vice versa. In other words, the claims (which, for example, relate to a device) can also be further developed with the features described or claimed in connection with a method. The corresponding functional features of the method are thereby implemented by corresponding physical modules.

[0011] Regardless of the grammatical gender of a particular term, persons with male, female or other gender identities are included.

[0012] The invention relates to a computer-implemented method for establishing compatibility between a patient table and a medical imaging system. The patient table is designed to position a patient during an examination with the medical imaging system. The method comprises a step of receiving the functionality of the patient table, which includes at least one function. The method further comprises a step of receiving the functionality of the medical imaging system, which also includes at least one function. The method further comprises a step of comparing the functionality of the patient table with the functionality of the medical imaging system.If at least one function is only included in the functionality of the patient table and / or only in the functionality of the medical imaging system, the procedure further includes a procedural step of blocking this at least one function.

[0013] The medical imaging system is designed to perform a patient examination. In particular, it captures medical image data of the patient, specifically a portion of the patient. This medical image data comprises a (partial) image of the patient.

[0014] The medical imaging system supports at least one function. This at least one function is included in the functionality of the medical imaging system. This function may be designed to acquire medical image data. For example, the function may include a patient table movement path for acquiring the medical image data, interfaces with the patient table, etc.

[0015] In embodiments of the invention, the functional scope of the medical imaging system can be received by means of a unique identifier. The identifier is unique with respect to the medical imaging system and specifies the functional scope of the medical imaging system. The identifier can be, in particular, electronic or mechanical. Alternatively, the functional scope can be received by means of a communication protocol.

[0016] The patient can be, in particular, a human being, an animal, a phantom, or any other object.

[0017] The patient table is designed to position a patient during an examination using the medical imaging system. Specifically, the patient table is designed to move the patient into the medical imaging system. In particular, the patient table is designed to move the patient into an opening of the medical imaging system.

[0018] The patient table supports at least one function. This at least one function is included in the patient table's range of functions. The function may, for example, include a movement path of the patient table for capturing medical image data, interfaces with the medical imaging system, etc.

[0019] In the process step of receiving the functional scope of the patient table, information is received about which functions the patient table supports. The functional scope of the patient table includes at least one function.

[0020] In embodiments of the invention, the functionality of the patient table can be received by means of a unique identifier. The identifier is unique with respect to the patient table and specifies its functionality. The identifier can be, in particular, electronic or mechanical. Alternatively, the functionality can be received via a communication protocol.

[0021] In the process step of receiving the functional scope of the medical imaging system, information is received about which functions are supported by the medical imaging system. The functional scope of the medical imaging system includes at least one function.

[0022] In the process step of comparing the functional scope of the patient table and the functional scope of the medical imaging system, the functions encompassed by the respective functional scopes are compared. Specifically, it is checked whether one or more functions are covered by only one of the functional scopes. In other words, it is checked whether the at least one function included in the functional scope of the patient table is also included in the functional scope of the medical imaging system. Likewise, it is checked whether the at least one function included in the functional scope of the medical imaging system is also included in the functional scope of the patient table. In particular, it is checked whether a specific instance of a function included in the functional scopes is identical.

[0023] If at least one function is covered by only one of the two functional scopes and / or a function covered by both functional scopes has a different form, this at least one function is blocked in the process step of blocking the at least one function. In other words, if the at least one function that is covered by the functional scope of the patient table is not covered by the functional scope of the medical imaging system, this function is blocked at the patient table. Likewise, the at least one function is blocked at the medical imaging system if the at least one function is covered by the functional scope of the medical imaging system but not by the functional scope of the patient table. Likewise, the function is blocked if the function is covered by both functional scopes, but in different forms.One characteristic can be defined, for example, by the length of a travel path. While both function sets can encompass a function that defines a travel path, this path can be different.

[0024] Locking means that the locked function can no longer be executed or used. For example, an interface can be deactivated by locking it.

[0025] Alternatively, locking can mean that a function is restricted or can only be used partially or in a limited form. This occurs particularly when the implementation of a function varies in its scope. For example, a travel path can be restricted by locking.

[0026] The inventor recognized that by comparing the functional scopes, it is possible to determine which functions are supported by only one of the two components: the medical imaging system or the patient table. The inventor further recognized that by disabling functions supported by only one of the two components, it is possible to prevent the use of functions not supported by both components, thus avoiding the possibility of an erroneous examination or its termination, which would be interpreted as a malfunction. Furthermore, this comparison allows for the determination of whether a function is implemented differently across the two functional scopes.By locking the corresponding function, the function of the respective component, the patient table or the medical imaging system, can be restricted in such a way that the functional characteristics of the two components are adapted to each other.

[0027] According to one aspect of the invention, the patient table is a mobile patient table.

[0028] The patient table is therefore mobile. It is enclosed by a patient positioning device. This device is designed to move the patient table along its travel path. The device also includes a base that supports the table. This base is mobile, allowing the patient table to be moved to different medical imaging systems. The mobile patient table can be moved along a rail system or by means of casters.

[0029] The inventor recognized that the patient table's flexible compatibility with various medical imaging systems makes it advantageously mobile. The inventor realized that this allows the mobile patient table to be used with different medical imaging systems and moved between them. The inventor recognized that this approach can accelerate and optimize workflows in a medical facility. In particular, it eliminates the need to reposition a patient who is to be examined with different medical imaging systems. Furthermore, it is unnecessary to wait until a specific patient table is available for a particular medical imaging system, as another patient table can be used with that system.Furthermore, one patient can be prepared for examination with the medical imaging system on one patient table while another patient is still being examined with the medical imaging system on a different patient table. This reduces or eliminates downtime for the medical imaging system.

[0030] According to another aspect of the invention, the medical imaging system is a magnetic resonance tomography system.

[0031] The magnetic resonance imaging (MRI) system preferably comprises a medical and / or diagnostic magnetic resonance device designed and / or configured for acquiring medical and / or diagnostic image data, in particular medical and / or diagnostic MRI image data, of a patient. The magnetic resonance device includes a scanner unit. The scanner unit of the magnetic resonance device preferably comprises a detector unit, in particular a magnet unit, for acquiring the medical and / or diagnostic image data. Advantageously, the scanner unit, in particular the magnet unit, comprises a body coil or a base magnet, a gradient coil unit, and a radio frequency antenna unit. The radio frequency antenna unit is fixedly arranged within the scanner unit and designed and / or configured for emitting an excitation pulse.To detect the magnetic resonance signals, the magnetic resonance device can have local high-frequency coils or local coils that are arranged around the area of ​​the patient being examined.

[0032] The body coil or base magnet of the scanner unit is designed to generate a homogeneous base magnetic field with a defined and / or specific magnetic field strength, such as a defined and / or specific magnetic field strength of 3 T or 1.5 T, etc. In particular, the base magnet is designed to generate a strong, constant, and homogeneous base magnetic field. The homogeneous base magnetic field is preferably located and / or present within the patient acquisition area of ​​the magnetic resonance device. The gradient coil unit is designed to generate magnetic field gradients that are used for spatial coding during imaging.

[0033] The patient acquisition area is designed and / or configured for receiving the patient, in particular the area of ​​the patient to be examined, for a medical magnetic resonance imaging (MRI) scan. For example, the patient acquisition area is cylindrical and / or surrounded by the scanner unit in a cylindrical shape. The scanner unit has a housing that at least partially surrounds the patient acquisition area. This housing can be a single piece and / or integral with the side of the scanner unit's high-frequency antenna facing the patient acquisition area, or it can be separate from the scanner unit's high-frequency antenna.

[0034] When the patient is moved into the MRI system or the body coil, he is positioned particularly in the patient acquisition area.

[0035] Within the patient acquisition area, a field of view (FOV) and / or an isocenter of the magnetic resonance imaging (MRI) device is preferably arranged. The FOV preferably comprises a detection area of ​​the MRI device within which the conditions for acquiring medical image data, in particular MRI image data, are present, such as a homogeneous background magnetic field. The isocenter of the MRI device preferably comprises the area and / or point within the MRI device that exhibits the optimal and / or ideal conditions for acquiring medical image data, in particular MRI image data. In particular, the isocenter comprises the most homogeneous magnetic field region within the MRI device.

[0036] The patient positioning device is designed for positioning and / or storing the patient for an examination. The patient positioning device includes the patient table, which is designed to be retractable into the patient acquisition area. For a magnetic resonance imaging (MRI) examination, the patient is positioned on the patient table such that, after positioning or moving the patient table along its travel path within the patient acquisition area, the area to be examined is located and / or positioned within the isocenter of the patient acquisition area.

[0037] For communication and / or information exchange between the patient and the medical operating personnel during an examination, the magnetic resonance imaging (MRI) device includes a communication unit. On the user side, the communication unit preferably includes a communication element, such as a communication console, for inputting and / or outputting communication data, such as information. Furthermore, the communication unit also includes at least one communication element on the patient side. In particular, the communication unit includes an acoustic and / or visual communication element. The acoustic communication element can be, for example, a loudspeaker or a microphone. The visual communication element can be, for example, a screen, in particular a touchscreen.

[0038] The inventor recognized that the method could be used, in particular, to ensure the compatibility of a patient table with an MRI system. Idle time during which no patient is being examined is especially costly with an MRI system and can be reduced with this method. Furthermore, different MRI systems have a wide variety of functions, which in turn must be compatible with different patient tables. To achieve the aforementioned advantages, the inventor realized that the method is particularly beneficial for MRI systems.

[0039] According to a further aspect of the invention, the at least one function included in the scope of functions of the patient table and / or the medical imaging system relates to one of the following functions: travel distance, number of slots for local coils, transmission path for a local coil, support for local shim coils, maximum supported patient weight, connection for a vacuum cushion, connection for a patient communication system, interfaces to other systems.

[0040] The travel distance, as a function of the patient table, indicates how far the patient table can be moved. Specifically, it indicates how far the patient table can be moved relative to its base. This travel distance can be limited by the mechanical stability of the patient positioning device and / or the patient's weight and / or the weight of any accessories used on the patient table.

[0041] The travel distance, as a function of the medical imaging system, indicates how far the patient table can be moved into the medical imaging system. In this case, the travel distance is limited by the presence of a support structure and / or the patient's weight on the table.

[0042] The number of local coil slots, as a function of the patient table, indicates how many local coils can be connected to the patient table. Specifically, the number of slots indicates where the slots are located on the patient table.

[0043] The number of local coil slots in the MRI system indicates how many local coils can be read by the MRI system, or rather, how many local coil signals can be used to reconstruct the medical image dataset. Specifically, the number of slots, as a function of the MRI system, indicates where the readable slots for local coils must be positioned on the patient table.

[0044] The transmission path for a local coil, as a function of the patient table, indicates whether the patient table provides a connection through which a local coil can be used to transmit a signal. This connection is designed to transmit the signal.

[0045] The transmission path for a local coil as a function of the medical imaging system indicates whether the medical imaging system is designed to provide a signal that can be transmitted via the connection of the patient table to the corresponding local coil and emitted by it.

[0046] The support for local shim coils as a function of the patient table indicates whether local shim coils can be connected to the patient table and, if so, how many.

[0047] The support for local shim coils as a function of the medical imaging system indicates whether and, if so, how many signals for local shim coils can be provided by the medical imaging system.

[0048] The maximum supported patient weight, as a function of the patient table, indicates the maximum weight a patient may have on the table. In other words, the maximum supported patient weight indicates the maximum weight the patient table is designed to support. Specifically, it indicates the maximum weight the patient table is mechanically stable enough to support, even during table adjustments.

[0049] The maximum supported patient weight, as a function of the medical imaging system, indicates the maximum weight a patient may have before being examined using the system. This maximum weight depends primarily on the support structure of the medical imaging system. This support structure supports the patient table during the procedure within the medical imaging system.

[0050] The connection for a vacuum cushion as a function of the patient table indicates whether and if so, where and how many vacuum cushions can be connected to the patient table for positioning the patient.

[0051] Similarly, the connection for a vacuum cushion, as a function of the medical imaging system, indicates whether and, if so, where and how many vacuum cushions can be supported for positioning the patient during the acquisition of the medical image data set.

[0052] The connection for a patient communication system, as a function of the patient table, indicates which communication systems are supported by the table. These systems are used to entertain the patient during the examination. Additionally, or alternatively, they allow the patient to communicate with the staff during the examination, as the medical personnel are typically located in a separate room. The patient communication system can include, for example, a wired or wireless alarm ball, headphones, a microphone, a screen, etc. The connection for a patient communication system specifies which of these communication systems can be connected to the patient table and which corresponding signals can be transmitted.

[0053] The connection for a patient communication system as a function of the medical imaging system indicates which of the above-mentioned possible communication systems can be connected to the medical imaging system and which signals can be transmitted.

[0054] The interfaces to other systems as a function of the patient table indicate which other systems can be connected to the patient table. In particular, it may specify whether the patient table includes a connection or interface for an electrocardiogram system (acronym: ECG system).

[0055] The interfaces to other systems as a function of the medical imaging system indicate which other systems can be connected to the medical imaging system and, in particular, which signals from which other systems can be processed by the medical imaging system and / or to which other systems the medical imaging system can provide a signal. For example, the interfaces to other systems can indicate whether the medical imaging system is designed to acquire an ECG-triggered image dataset or to perform an ECG-triggered examination and can further process the signal from an ECG system for this purpose.

[0056] The inventor recognized that a multitude of functions must be compatible between a medical imaging system and a patient table in order for the two to work together. In particular, these functions must be compatible to ensure safe and virtually error-free operation.

[0057] According to a further aspect of the invention, the functionality of the patient table includes a function that specifies a first number of slots for local coils. The functionality of the medical imaging system includes a function that specifies a second number of slots for local coils, the first being greater than the second. The locking process includes a step of locking the slots on the patient table that are not specified by the function of the medical imaging system.

[0058] A local coil is designed to capture and provide a signal or data during the examination. The medical imaging system can then read the data from the local coils and use it to determine the medical image data.

[0059] The first number of slots for local coils indicates how many local coils can be connected to the patient table. Specifically, this number specifies the position of each slot on the table. Each slot is assigned a particular position. The second number of slots indicates how many local coils can be connected to the medical imaging system and thus read by it. During readout, data acquired by the local coils is retrieved. Specifically, this second number of slots indicates the positions on the patient table from which a local coil can be connected to the medical imaging system, and conversely, from which positions on the patient table the acquired data can be retrieved.If the first number is greater than the second number, this means that more local coils can be connected to the patient table than can be read by the medical imaging system. Specifically, this means that some slots on the patient table are located in positions that cannot be read by the medical imaging system. In the blocking step, enough slots on the patient table are blocked so that the number of unblocked slots equals the second number of slots. In other words, enough slots are blocked to ensure that the maximum number of local coils that can be connected to the patient table is equal to the number that can be read by the medical imaging system.In particular, the slots on the patient table that are located in positions on the patient table that cannot be read by the medical imaging system are blocked.

[0060] Locking means that no data can be read from or fed into a local coil connected to a locked slot.

[0061] In particular, the maximum number of available slots, i.e., the number of unlocked slots, can be displayed to medical personnel. Specifically, it can be shown to medical personnel which slots are locked and which are unlocked. This information can be displayed on a user interface, specifically via a display device such as a monitor or screen.

[0062] When locking, it is advantageous to lock those slots on the patient table that are positioned in such a way that they cannot be connected to or read by the medical imaging system, since the position of these slots is not included in the functionality of the medical imaging system.

[0063] Alternatively, a specific order can be predefined for locking the slots on the patient table. For example, if the first number is one greater than the second number, slot A is locked. If the first number is two greater than the second number, slot A is locked first, then slot B, and so on.

[0064] Alternatively, the ports to which a local coil is to be connected last, or to which no local coil will be connected, can be locked. For example, a medical operator can connect several local coils to the patient table one after the other. As soon as the number of connected local coils exceeds the second number, the remaining free ports on the patient table are locked.

[0065] The inventor recognized that locking the coil prevents it from being connected to a position on the patient table that cannot be read by the medical imaging system. This ensures that a patient table capable of being moved to capture a full-body image of the patient is also compatible with a medical imaging system that only supports a movement range allowing for partial-body images. Furthermore, the inventor recognized that locking the coil prevents the connection of too many local coils, which would prevent the medical imaging system from reading the data acquired by the coils and thus render the data lost. This could lead to errors in the examination, as not all acquired data could be retrieved.By blocking the corresponding slots, it is ensured that the data acquired with the local coils can actually be read out and used to determine the medical image data.

[0066] According to a further aspect of the invention, the functionality of the patient table includes a function that specifies a first maximum travel distance of the patient table. Furthermore, the functionality of the medical imaging system includes a function that specifies a second maximum travel distance of the patient table. The first maximum travel distance is greater than the second maximum travel distance. The locking function comprises a process step of restricting the control of the patient table such that the patient table can only be moved along the second maximum travel distance.

[0067] The first maximum travel distance of the patient table indicates the maximum distance the patient table can travel along a specific path for an examination. Specifically, the first maximum travel distance indicates the maximum distance the patient table can travel in one direction relative to its base. This first maximum travel distance is independent of the patient table's mobility via its base, making it a mobile patient table. The first maximum travel distance is used to move the patient table into the medical imaging system.

[0068] The second maximum travel distance specifies the maximum distance a patient table can be moved into the medical imaging system. This distance may be determined by a support structure within the medical imaging system, which ensures its mechanical stability during table movement. Alternatively or additionally, the second maximum travel distance may depend on the patient's weight.

[0069] When restricting the control of the patient table, the control is restricted in such a way that the patient table can be moved into the medical imaging system by a maximum of the second maximum travel distance.

[0070] In particular, a procedure of the patient table into the medical imaging system can be terminated if the path already traveled exceeds the second maximum travel distance.

[0071] In particular, a medical operator can be notified that the patient table's travel distance is limited to the second maximum travel distance. This notification can be displayed via a user interface, specifically a display device such as a screen or monitor, as described above.

[0072] The inventor recognized that by limiting the travel distance of the patient table, or by controlling the patient table in such a way that the patient table can only travel a maximum of two maximum travel distances, the stability of the medical imaging system is ensured. In other words, this prevents the patient table from being moved too far into the medical imaging system, which could lead to instability and potentially damage to the medical imaging system, and in the worst case, injury to the patient.

[0073] According to another aspect of the invention, the functionality of the patient table includes a function that specifies a first maximum travel distance of the patient table. Furthermore, the functionality of the medical imaging system includes a function that specifies a second maximum travel distance of the patient table. The first maximum travel distance is different from the second maximum travel distance. The method also includes a process step of receiving a measurement protocol. This measurement protocol specifies a measurement travel distance required for performing the examination with the medical imaging system. The locking process includes a process step of checking whether the measurement travel distance is greater than the first and / or second maximum travel distance.The locking process also includes a procedural step of adjusting the measurement travel distance in the measurement protocol so that the measurement travel distance corresponds to the smaller of the first or the second maximum travel distance.

[0074] The first and second maximum travel distances are designed in particular as described above.

[0075] The measurement protocol is designed to perform or initiate the examination using the medical imaging system. The measurement protocol includes functions necessary for the examination. In particular, the measurement protocol defines the measurement parameters of these functions required for conducting the examination. Specifically, the measurement travel distance is defined in the measurement protocol as a measurement function. The measurement travel distance specifies the maximum distance the patient must be moved into the medical imaging system for the examination.

[0076] In the process step of receiving the measurement protocol, the protocol can be received from a database. The protocol can thus be stored in the database and retrieved when the examination is to be performed. Alternatively, the protocol can be received via a user interface. A medical operator can create and / or modify the protocol at the user interface.

[0077] In the procedure step of checking whether the measuring travel distance is greater than the first and / or second maximum travel distance, the measuring travel distance is compared with the first and the second maximum travel distance.

[0078] In the procedure step of adjusting the measurement travel distance, the measurement travel distance in the measurement protocol is adjusted if it is greater than at least the first maximum travel distance or the second maximum travel distance. The measurement travel distance is adjusted so that the adjusted measurement travel distance corresponds to the smaller of the first or second maximum travel distances. In particular, this ensures that during the examination, the patient table is moved by no more than the smallest of the following values: measurement travel distance, first maximum travel distance, and second maximum travel distance.

[0079] Furthermore, the medical operator can be shown information indicating that the measurement travel distance has been adjusted. This information about the adjustment of the measurement travel distance can be displayed, in particular, via the user interface described above. This information about the adjustment of the measurement travel distance can be displayed, in particular, via the display device described above.

[0080] The inventor recognized that by adapting the measurement protocol, the stability of the patient table and the medical imaging system can be ensured at all times. In other words, it is ensured that the patient table is not moved too far into a position that is no longer supported by the patient table and / or the medical imaging system. The inventor also recognized that this approach ensures the compatibility of the measurement protocols. This is particularly necessary when universal measurement protocols are stored, for example, in a database, which must be adapted to a specific combination of patient table and medical imaging system.

[0081] According to a further aspect of the invention, the method also includes a process step of receiving a measurement protocol. This measurement protocol includes measurement functions required for conducting the examination with the medical imaging system. The blocking process includes a process step of checking whether at least one of the measurement functions is not included in the functionality of the patient table and / or the functionality of the medical imaging system. The blocking process also includes a process step of providing information indicating which of the measurement functions is not included in the functionality of the patient table and / or the functionality of the medical imaging system.

[0082] The measurement protocol includes measurement functions required or used for conducting the examination. In particular, the measurement protocol defines measurement parameters for these functions. Each measurement function specifies a function of the patient table and / or the medical imaging system required for the examination. The measurement parameter can then further define the configuration of this function or specify a value for its functionality.

[0083] In the process step of receiving the measurement protocol, the measurement protocol is received as described above.

[0084] In the procedural step of checking whether at least one of the measurement functions is not included in the scope of functions of the patient table and / or the medical imaging system, it is checked whether each of the measurement functions is included in the scope of functions of the patient table and the medical imaging system.

[0085] In the process step of providing information about which measurement functions are not included in the functionality of the patient table and / or the medical imaging system, information about the result of the verification process step is provided. Specifically, the information indicates which measurement function is not included in the functionality of the patient table and the medical imaging system.

[0086] The information is provided specifically to medical personnel. This information can be provided, in particular, via a user interface. The information can be displayed, in particular, by means of a display device. The display device can be, in particular, a monitor or a screen.

[0087] The inventor recognized that this allows the identification of measurement functions in a measurement protocol that cannot be used. Specifically, these measurement functions cannot be used because the corresponding functions of the patient table or the medical imaging system are locked or not included in the relevant functional scope.

[0088] According to one aspect of the invention, the locking also includes a process step of adapting the measurement protocol in such a way that the measurement functions are adapted so that all measurement functions are covered by the functional scope of the patient table and by the functional scope of the medical imaging system.

[0089] The adaptation can be automated, in particular, by replacing a measurement function that is not included in the functional scope of the medical imaging system and the patient table with an equivalent function that is included in both functional scopes.

[0090] Alternatively, the adjustment can be made by prompting the operator to modify, replace, or remove the relevant measurement function that is not covered by both sets of functions, so that the modified measurement function is covered by both sets of functions. This prompt can be provided via the user interface or display device described above.

[0091] Alternatively, a suitable alternative measurement protocol can be received during the adaptation process step. The process steps of checking whether at least one of the measurement functions of the newly received measurement protocol is not covered by both sets of functions, providing information about the result of this check, and, if necessary, adapting the protocol, are performed analogously for the newly received measurement protocol.

[0092] The inventor recognized that this method ensures the desired examination can be performed using the existing functionality of the patient table and the medical imaging system. The inventor also recognized that this method prevents or reduces the occurrence of errors.

[0093] The invention also relates to a compatibility system for establishing compatibility between a patient table and a medical imaging system. The patient table is designed to position a patient during an examination with the medical imaging system.

In addition to the computer program, such a computer program product may optionally include additional components such as documentation and / or other components, as well as hardware components such as hardware keys (dongles, etc.) for using the software.

[0096] In particular, the invention also relates to a computer program product comprising a computer program that can be directly loaded into a memory of a compatibility system, with program sections to execute all steps of the above-described method for establishing compatibility between a patient table and a medical imaging system and its aspects when the program sections are executed by the compatibility system.

[0098] The properties, features, and advantages of this invention described above become clearer and more understandable in conjunction with the following figures and their descriptions. The figures and descriptions are not intended to limit the invention or its embodiments in any way.

[0099] In various figures, identical components are labeled with corresponding reference symbols. The figures are generally not to scale.

[0100] They show Fig. 1 a first embodiment of a method for establishing compatibility between a patient table and a medical imaging system, Fig. 2 a second embodiment of a method for establishing compatibility between a patient table and a medical imaging system, Fig. 3 a third embodiment of a method for establishing compatibility between a patient table and a medical imaging system, Fig. 4 a compatibility system for establishing compatibility between a patient table and a medical imaging system, Fig. 5 an embodiment of a magnetic resonance tomography system.

[0101] Fig. Figure 1 shows a first embodiment of a method for establishing compatibility between a patient table 15 and a medical imaging system.

[0102] The patient table 15 is designed to position a patient 13 during an examination with the medical imaging system. Specifically, the patient table 15 is designed to move the patient 13 into the medical imaging system for the examination. For this purpose, a lying surface of the patient table is moved relative to a base 15b of the patient table 15.

[0103] The patient table 15 can be designed to be mobile. A mobile patient table 15 is designed to move back and forth between different medical imaging systems. In particular, the patient table 15 can be moved using its base 15b. In particular, the mobile patient table 15 can be designed to be moved along a rail system or by means of a roller system.

[0104] The medical imaging system is designed to capture a medical image data set of the patient 13 lying on the patient table 15 during an examination.

[0105] In embodiments of the invention, the medical imaging system can in particular be a magnetic resonance imaging (acronym: MRI) system 1. One embodiment of an MRI system 1 is described in Fig. 5 described.

[0106] In a process step REC-1 of receiving a functional scope of the patient table 15, the functional scope is received, which comprises the functions supported by the patient table 15. The functional scope of the patient table 15 includes at least one function. The functional scope of the patient table 15 can be transmitted by means of an electrical or mechanical identifier or by means of a communication protocol.

[0107] In a process step of receiving REC-2 a functional scope of the medical imaging system, the functional scope is received, which comprises the functions supported by the medical imaging system. The functional scope of the medical imaging system includes at least one function. The functional scope of the medical imaging system can be transmitted using an electrical or mechanical identifier or using a communication protocol.

[0108] The functions of the functional scope of the patient table 15 or the medical imaging system may, for example, relate to mechanical functional parameters and / or interfaces, etc.

[0109] In particular, at least one function included in the scope of functions of the patient table 15 and / or the medical imaging system may relate to one of the following functions: travel distance, number of slots for local coils, transmission path for a local coil, support for local shim coils, maximum supported patient weight, connection for a vacuum cushion, connection for a patient communication system, interfaces to other systems.

[0110] The travel distance indicates the maximum extent to which the patient table 15 can be moved into the medical imaging system. This maximum travel distance is limited by the mechanics of the patient table 15, a support structure of the medical imaging system, the weight of the patient 13, and / or the spatial arrangement of the medical imaging system. The maximum travel distance of the patient table 15 may differ from the maximum travel distance of the medical imaging system. In such cases, the functional scopes include different functions with respect to the maximum travel distance.

[0111] The number of local coil slots indicates how many slots the patient table or medical imaging system has. Specifically, the number of local coil slots determines the position of each slot on the patient table. Each slot is assigned a specific position on the table. If the patient table and the medical imaging system have a different number of slots, the respective functions of each slot will differ.

[0112] A local coil is used in an MRI system to receive signals.

[0113] The transmit path for a local coil indicates whether one of the local coils for which a slot is available can also be used as a transmitting coil. For this purpose, the corresponding slot is equipped with a transmit path, i.e., a line for the transmit signal. If the patient table includes the function of the transmit path for the local coil, the corresponding line to the corresponding slot in the patient table 15 is provided or configured. If the medical imaging system includes the function of the transmit path for the local coil, the medical imaging system is configured to provide the corresponding signal for transmission via the local coil.

[0114] Local shim coil support indicates whether a local shim coil is supported and, if so, how many.

[0115] The maximum supported patient weight indicates the maximum weight a patient can weigh while positioned on the patient table. This maximum supported patient weight can particularly affect the maximum travel distance. If the functionality of the patient table 15 and the functionality of the medical imaging system specify different maximum patient weights, the corresponding functions will also differ.

[0116] The function regarding the connection of a vacuum cushion indicates whether the patient table or medical imaging system supports the use of a vacuum cushion.

[0117] The function of a patient communication system connection specifies which forms of patient communication can be connected to the patient table or medical imaging system, or for which forms of patient communication a signal can be sent and / or received. The patient communication system can, for example, include a display device and / or headphones and / or a microphone and / or an alarm ball (wired or wireless). All of these describe forms of patient communication.

[0118] The functions relating to interfaces with other systems specify which interfaces are provided for a connection to another system. Such an other system could, for example, be an ECG system. The patient table 15 can be designed to receive an ECG signal measured by an ECG system if it includes a corresponding interface. The medical imaging system can be configured to further process the ECG signal and, if necessary, adapt the examination to the ECG signal if it has the corresponding interface.

[0119] In a further step of the COMP comparison process, the functional scope of patient table 15 is compared with the functional scope of the medical imaging system. In particular, it is checked whether a function is covered by only one of the two functional scopes.

[0120] If, during the COMP comparison, at least one function is only covered by the functionality of the patient table 15 or only by the functionality of the medical imaging system, this function is locked in a LOCK procedure step. A locked function is no longer usable or executable. Alternatively, locking a function means restricting its functionality. In this case, the locked function is only usable to a limited extent.

[0121] Fig. Figure 2 shows a second embodiment of a method for establishing compatibility between a patient table 15 and a medical imaging system.

[0122] The process steps of receiving REC-1 of a function set of patient table 15, receiving REC-2 of a function set of the medical imaging system, comparing COMP of the function set of patient table 15 and the function set of the medical imaging system, and locking LOCK of a function based on the comparison COMP are carried out according to the description. Fig. 1 executed.

[0123] According to the exemplary embodiment, the functionality of the patient table 15 can specify a first number of slots for local coils, and the functionality of the medical imaging system can specify a second number of slots for local coils. The first number can be greater than the second number.

[0124] Specifically, the first number specifies a position on the patient table for each slot (15). Specifically, the second number specifies where each slot that can be connected to or read from the medical imaging system may be positioned on the patient table.

[0125] The locking procedure step LOCK then includes a locking procedure step LOCK-L of the slots on patient table 15 that are not specified by the functionality of the medical imaging system. The locked slots are deactivated. This means that no signal is received or transmitted from these slots.

[0126] If the positions of the slots are defined by the first and second numbers, then when the LOCK function is activated, those slots on patient table 15 whose position is not defined by the second number are locked. In other words, depending on their position on patient table 15, those slots are locked that cannot be connected to and / or read by the medical imaging system because the corresponding position is not supported by the medical imaging system according to its functional scope.

[0127] In embodiments of the invention, a sequence may be provided in which the sockets on the patient table 15 are deactivated. Alternatively, the sockets that are connected last or that remain after connecting the local coils may be deactivated.

[0128] Alternatively or additionally, the functionality of the patient table 15 includes a first maximum travel path of the patient table 15, and the functionality of the medical imaging system includes a second maximum travel path of the patient table 15. The first maximum travel path can be greater than the second maximum travel path. If this is the case, the locking function (LOCK) includes a procedural step (RES) of restricting the control of the patient table 15 such that the patient table 15 can only be moved along the second maximum travel path.

[0129] Fig. Figure 3 shows a third embodiment of a method for establishing compatibility between a patient table 15 and a medical imaging system.

[0130] The process steps of receiving REC-1 of a function set of patient table 15, receiving REC-2 of a function set of the medical imaging system, comparing COMP of the function set of patient table 15 and the function set of the medical imaging system, and locking LOCK of a function based on the comparison COMP are carried out according to the description. Fig. 1 executed.

[0131] The third embodiment can also be combined with the second embodiment.

[0132] According to the exemplary embodiment, the scope of functions of the patient table 15 specifies a first maximum travel distance of the patient table 15 and the scope of functions of the medical imaging system specifies a second maximum travel distance of the patient table 15.

[0133] The procedure includes a process step of receiving a measurement protocol (REC-3). The measurement protocol is designed to control the medical imaging system and the patient table 15 during the examination. The measurement protocol specifically includes measurement functions that describe, define, or specify the functions required for the examination. During reception, the measurement protocol is received from a database. A large number of measurement protocols can be stored in the database. Alternatively, the measurement protocol can be provided via a user interface. In this case, the medical operator can define and provide the measurement protocol via the user interface.

[0134] The locking process (LOCK) includes a procedure step (CHECK-2) to check whether at least one of the measurement functions is not included in the functionality of the patient table 15 and / or the functionality of the medical imaging system. In other words, it is checked whether all measurement functions are included in the functionality of the patient table 15 and the functionality of the medical imaging system. If this is not the case, the locking process (LOCK) includes a further procedure step (PROV) to provide information about which measurement functions are not included in the functionality of the patient table and / or the functionality of the medical imaging system. This information can be provided, in particular, to medical personnel.

[0135] Optionally, the locking mechanism (LOCK) can also include a procedure step (ADA-2) of adapting the measurement protocol. In this process, the measurement protocol is adapted so that all measurement functions are covered by the functionality of the patient table 15 and the functionality of the medical imaging system.

[0136] In particular, the operating personnel may be asked to adapt the measurement protocol in such a way that all measurement functions are covered by the functional scope of the patient table 15 and by the functional scope of the medical imaging system.

[0137] Alternatively, the measurement function(s) not covered by both sets of functions can be automatically replaced, restricted, or deleted by an equivalent measurement function. Restricting the measurement function can be done as described below with regard to the travel distance.

[0138] Alternatively, the measurement protocol can be adapted by receiving a new one. For the newly received measurement protocol, the steps of checking CHECK-2, deploying PROV, and, if necessary, adapting ADA-2 are repeated.

[0139] Alternatively, the measurement protocol configured as described above can be received in a single REC-4 reception step as described above. One of the measurement functions specifies a measurement travel distance. The measurement travel distance is the maximum distance the patient table 15 must travel to perform the examination.

[0140] The locking mechanism (LOCK) then includes a procedure step (CHECK-1) to check whether the measuring travel distance is greater than the first and / or the second maximum travel distance. If the measuring travel distance is greater than either of the two maximum travel distances, the locking mechanism (LOCK) also includes a procedure step (ADA-1) to adjust the measuring travel distance in the measurement protocol so that the measuring travel distance corresponds to the smaller of the first or the second maximum travel distance. In other words, it is ensured, if necessary, that the measuring travel distance always corresponds to the smallest of the maximum travel distances.

[0141] Fig. Figure 4 shows a compatibility system SYS for establishing compatibility between a patient table and a medical imaging system.

[0142] The illustrated compatibility system SYS for establishing compatibility between a patient table and a medical imaging system is designed to execute a method according to the invention for establishing compatibility between a patient table and a medical imaging system.

[0143] The compatibility system SYS can be, in particular, a computer, a microcontroller, or an integrated circuit (IC). Alternatively, the compatibility system SYS can be a real or virtual computer network (a technical term for a real computer network is "cluster," a technical term for a virtual computer network is "cloud"). The compatibility system SYS can be implemented as a virtual system running on a computer, a real computer network, or a virtual computer network (a technical term for this is "virtualization").

[0144] The SYS.IF interface can be a hardware or software interface (for example, a PCI bus, USB, or FireWire). The SYS.CU processing unit can comprise hardware and / or software components, such as a microprocessor or an FPGA (Field Programmable Gate Array). The SYS.MU storage unit can be configured as random access memory (RAM) or as permanent mass storage (hard drive, USB flash drive, SD card, solid state drive (SSD)).

[0145] The interface SYS.IF can, in particular, comprise a plurality of sub-interfaces that execute different process steps of the respective method according to the invention. In other words, the interface SYS.IF can be configured as a plurality of SYS.IF interfaces. The computing unit SYS.CU can, in particular, comprise a plurality of sub-computing units that execute different process steps of the respective method according to the invention. In other words, the computing unit SYS.CU can be configured as a plurality of SYS.CU computing units.

The MRI device 10 also has a patient acquisition area 12 for imaging a patient 13. In the present embodiment, the patient acquisition area 12 is cylindrical and is surrounded in a cylindrical shape in one circumferential direction by the scanner unit 11, in particular by the magnetic unit. However, a different configuration of the patient acquisition area 12 is conceivable. The patient 13 can be moved into the patient acquisition area 12 by means of a patient positioning device 14 of the MRI system 1. For this purpose, the patient positioning device 14 has a patient table 15 that is movable within the patient acquisition area 12.In particular, the patient table 15 is mounted so as to be movable in the longitudinal direction of the patient receiving area 12 and / or in the z-direction. The patient table 15 is designed to be movable relative to its base 15b. The base 15b is designed to support or hold a lying surface of the patient table 15 from below. In embodiments of the invention, the patient table 15 is a mobile patient table. In this embodiment, the patient table 15 is designed to be movable by means of a roller system and / or a rail system via its base 15b.

[0149] The patient reception area 12 comprises an enclosure 36 surrounding the patient reception area 12, with an inner wall 37. In the present embodiment, the enclosure 36 surrounding the patient reception area 12 is formed integrally with the high-frequency antenna unit 20, in particular with a side of the high-frequency antenna unit 20 facing the patient reception area 12. In an alternative embodiment of the invention, the enclosure 36 surrounding the patient reception area 12 can also form a separate unit from the high-frequency antenna unit 20.

[0150] The scanner unit 11, in particular the magnet unit, comprises a superconducting base magnet or body coil 16 for generating a strong and, in particular, constant base magnetic field 17. Furthermore, the scanner unit 11, in particular the magnet unit, includes a gradient coil unit 18 for generating magnetic field gradients, which are used for spatial coding during imaging. The gradient coil unit 18 is controlled by a gradient control unit 19 of the MRI system 1.

The high-frequency antenna unit 20 is controlled by a high-frequency antenna control unit 21 of the MRI system 1 and transmits high-frequency magnetic resonance sequences into the patient acquisition area 12 of the magnetic resonance device 10.

[0151] The MRI system 1 has a system control unit 22 for controlling the body coil 16, the gradient control unit 19, and the high-frequency antenna control unit 21. The system control unit 22 centrally controls the MRI system 1, for example, by performing a predetermined imaging gradient echo sequence. In addition, the system control unit 22 includes an evaluation unit (not shown) for evaluating medical image data or MRI image data acquired during the magnetic resonance examination.

[0152] Furthermore, the MRI system 1 includes a user interface 23, which is connected to the system control unit 22. Control information, such as imaging parameters, as well as reconstructed MRI image data, can be displayed on a display unit 24, for example, on at least one monitor, of the user interface 23 for medical operators. The user interface 23 also has an input unit 25, by means of which information and / or parameters can be entered by the medical operators during a measurement procedure.

[0153] Furthermore, the user interface 23 can be configured to issue a warning if a travel path setting by the medical operator or by an examination protocol exceeds the specified maximum travel path. In particular, the user interface 23 can be configured to issue a message if the specified maximum travel path is less than the maximum possible travel path.

[0154] The scanner unit 11 of the magnetic resonance imaging (MRI) device 10 is located together with the patient positioning device 14 within an examination room 26. The system control unit 22, on the other hand, is located together with the user interface 23 within a control room 27. The control room 27 is separate from the examination room 26. In particular, the examination room 26 is shielded from radiofrequency radiation from the control room 27. During an examination, the patient 13 is located within the examination room 26, while the medical personnel are usually located within the control room 27.

[0155] For communication and / or information exchange between the patient 13 and the medical operating personnel during an examination, the MRI system 1 has a communication unit 28. The communication unit 28 has a communication element on the operator side, designed as an operator console 29. The communication element, in particular the operator console 28, is preferably arranged within the control room 27. The operator console 29 has an input element 30 and an output element 31. The input element 30 and / or the output element 31 can be configured as an acoustic and / or visual input element 30 and / or output element 31.

[0156] Furthermore, the communication unit 28 on the patient side has a first communication element, which is designed as an input element 32. Using the input element 32, the patient 13 can communicate their condition, such as discomfort, to the operator, in particular the medical staff, during the examination. In the present embodiment, the input element 32 is designed as a patient call ball or alarm ball. However, in principle, other input elements 32 that would be useful to someone skilled in the art, such as a microphone, etc., are possible in a further embodiment of the communication unit 28.

[0157] The depicted MRI system 1 can, of course, include other components that MRI systems 1 typically have. Furthermore, the general operating principle of an MRI system 1 is known to those skilled in the art, so a detailed description of the other components is omitted.

[0158] Where not explicitly stated, but sensible and in line with the invention, individual embodiments, individual aspects or features thereof may be combined or exchanged without departing from the scope of the present invention. Advantages of the invention described with reference to one embodiment also apply to other embodiments, where applicable, without explicit mention.
