[0049] Specifically, it can be specified that the track of the track system can be received in a shape-locking manner into the track groove, by means of the track being placed into the track groove, particularly by the track being placed into the track groove in a vertical downward direction relative to the load-bearing profile, perpendicular to the longitudinal axis of the track. For this purpose, the load-bearing profile can, for example, be constructed without an undercut and / or in multiple pieces, such that the undercut is only formed after the track of the track system is placed into the track groove and the load-bearing profile is subsequently assembled.

[0050] Optionally, the carriage and track system are designed to forcefully transmit the driving force for the translational movement of the computed tomography gantry from the carriage to, in particular, through friction, the track system.

[0051] Specifically, it can be specified that the track system is stationary relative to the base surface and / or is fixedly anchored relative to the base surface. It can also be specified that the object being inspected is stationary relative to the track system and / or relative to the base surface. The track system can, in particular, form a linear guide for the carriage.

[0052] For example, a medical imaging system may have an examination table for supporting the object being examined. The examination table may, in particular, be stationary relative to a track system and / or relative to a base surface and / or fixedly anchored relative to the track system and / or relative to a base surface. For example, the object being examined may be a person to be examined, especially a patient, and / or supported on the examination table, particularly supported stationary relative to the examination table.

[0053] Translational movements can be performed relative to the track system, relative to the base surface, relative to the inspection table, and / or relative to the object being inspected. Translational movements can be substantially horizontal. The base surface can be substantially horizontal. The base surface can be the floor of the inspection chamber and / or be made of concrete.

[0054] For example, a computed tomography (CT) gantry can have a support frame and a rotor rotatably supported relative to the support frame, wherein a radiation source and a radiation detector are arranged on the rotor. Optionally, the CT gantry can have an inclined frame tilted relative to the support frame, wherein the rotor is arranged on the inclined frame. The radiation source and radiation detector can interact to receive projection data from the object being examined. For example, the CT gantry can have an opening. In particular, the track system, the examination table, and the opening can be arranged relative to each other such that the examination table is guided into the opening by translational movement of the CT gantry, especially the examination table together with the object being examined supported on the examination table.

[0055] The implementation method specifies that a set of wheel-track rolling contacts is constructed between the carriage and the track system, wherein the carriage and the track system are designed to forcefully transmit the driving force for the translational movement of the computed tomography gantry from the carriage to the track system by means of the set of wheel-track rolling contacts.

[0056] The implementation specifies that the set of wheel-track rolling contacts absorbs the total weight of the carriage and the computed tomography (CT) gantry, wherein each wheel-track rolling contact (which is included in the set of wheel-track rolling contacts and absorbs at least a portion of the total weight of the carriage and the CT gantry) is force-locked and transmitted, in particular, at least a portion of the driving force for the translational movement of the CT gantry is transmitted by friction.

[0057] Specifically, it can be stipulated that at least a portion of the total weight of the carriage and the computed tomography gantry is not negligible, for example, greater than one-tenth of the total weight of the carriage and the computed tomography gantry. Specifically, it can be stipulated that at least a portion of the driving force for the translational movement of the computed tomography gantry is not negligible, for example, greater than one-tenth of the driving force for the translational movement of the computed tomography gantry.

[0058] For medical imaging systems, the presence of wheel-track rolling contacts can be excluded, as they absorb a portion of the total weight of the carriage and computed tomography gantry but do not transmit a portion of the driving force for the translational movement of the computed tomography gantry.

[0059] The available friction force for the drive depends on the friction value and the normal force acting on the friction wheel. Especially when the wheels are directly driven and the friction of the wheel-rail rolling contact is utilized, the total weight of the carriage and the computed tomography frame can be used as the normal force. In the friction wheel, there is a weight distribution between the rail wheel and the friction wheel, so only a portion of the weight is available as the normal force.

[0060] The implementation specifies that the track system has a set of tracks, wherein the carriage has a set of wheels, wherein the set of wheels is rolled on the set of tracks. The set of tracks may, for example, be the tracks of a track system. The set of tracks may, for example, have a first track and / or a second track of a track system.

[0061] Specifically, it can be specified that the set of rails and the set of wheels constitute the set of wheel-rail rolling contacts. Specifically, it can be specified that each rail in the set of rails is a circular rail, and / or each wheel in the set of wheels is a concave roller, and / or constructed for rolling on the circular rails. The rails and / or wheels can, for example, be made of steel.

[0062] Circular rails, in particular, can be integrated into the floor without covers and drive elements, and can be traversed by patient beds and instrument tables. The driving force for the translational movement of the computed tomography gantry can be transmitted from the carriage to the track system, for example, based on the force-locking, especially friction-locking, between the wheels of the set of wheels and the tracks of the set of rails.

[0063] The implementation specifies that, for each wheel in the set of wheels, the carriage has a wheel direct drive that interacts with the wheel and proportionally contributes to the driving force for the translational movement of the computed tomography (CT) gantry. Specifically, it can be specified that, for each wheel, the wheel direct drive (which interacts with the wheel) directly drives the wheel and thereby proportionally contributes to the driving force for the translational movement of the CT gantry. More specifically, it can be specified that the driving force for the translational movement of the CT gantry is generated jointly by the wheel direct drives of multiple wheels in the set of wheels. The wheel direct drives can, for example, be electric motors, particularly hub motors.

[0064] The implementation method specifies that the medical imaging system also has a position measurement system, and the position measurement system is designed to generate position information, wherein the position information relates to the position of the computed tomography gantry along the track system.

[0065] The position of the computed tomography (CT) gantry along the track system can be defined, in particular, relative to a reference point that is stationary relative to the base and / or relative to the track system, especially during the translational movement of the CT gantry. Specifically, it can be specified that the position of the CT gantry along the track system is continuously measured, particularly at a sufficiently high sampling rate, during the translational movement of the CT gantry, such that positional information for each projection dataset includes the recording of the position of the projection dataset by the CT gantry from the object being examined, during the translational movement of the CT gantry.

[0066] The implementation method specifies that the position measurement system is designed to generate position information based on measurements, particularly based on the position of a non-contact computed tomography gantry along the track system.

[0067] Non-contact measurements can be performed, for example, optically, magnetically, magnetostrictively, inductively, and / or capacitively, and / or based on runtime. The combination of the driving force transmission via force-locking between the wheel and track on one hand, and non-contact position measurement on the other, enables precise positioning and carriage position identification within a minimal embedding surface, where form-locking can be abandoned in both driving and position measurement. This improves cleanability and reduces wear.

[0068] The position of the computed tomography gantry along the track system can be measured either absolutely, for example by means of an absolute encoder, or incrementally, for example by means of an incremental encoder.

[0069] The implementation specifies that the position measurement system has a measuring track and a position sensor, wherein the measuring track is stationary relative to the track system and extends along the track system, and wherein the position sensor is connected to a carriage such that it follows the translational movement of the computed tomography gantry and interacts with the measuring track during the translational movement of the computed tomography gantry, in particular to perform measurements, especially non-contact measurements of the position of the computed tomography gantry along the track system.

[0070] The measuring track can be, for example, a code track. Position sensors are particularly designed for scanning code tracks. The measuring track can be, for example, a magnetic tape. The magnetic tape can be magnetized at regular intervals. The measuring track can be, for example, a measuring strip, especially a stainless steel measuring strip, and / or fixedly anchored relative to the bottom surface.

[0071] The implementation specifies that the medical imaging system further includes a support profile, and the support profile has a measuring track groove for accommodating, in particular, shape-locking the measuring track, and the measuring track is accommodated, in particular, shape-lockingly accommodated in the measuring track groove, wherein the support profile has a track groove for shape-lockingly accommodating the track of the track system, and the track of the track system is shape-lockingly accommodated in the track groove.

[0072] Specifically, it can be specified that the load-bearing profile extends along the track system and / or the load-bearing profile is fixedly anchored relative to the bottom surface. In particular, the measuring track groove and the track groove can be arranged substantially parallel to each other. In particular, the measuring track can be bonded to the load-bearing profile.

[0073] The implementation method specifies that the medical imaging system also has a data processing unit, and the data processing unit is designed to calculate a drive signal based on position information, wherein the carriage has a travel drive, and the travel drive is designed to generate a drive force for the translational movement of the computed tomography gantry according to the drive signal.

[0074] In particular, it can be stipulated that the direct drive of multiple wheels in this group of wheels together forms a driving drive.

[0075] Therefore, a medical system is also disclosed, which has a load-bearing structure, a carriage and track system, and load-bearing profiles.

[0076] - The load-bearing structure is movably supported by a carriage and a track system, allowing the load-bearing structure to translate relative to the bottom surface along the track system.
