Abstract

The present invention relates to a data processing method of determining at least one operating parameter of a medical imaging device, the method being executed by a computer and comprising the following steps:
a) acquiring entity geometry data comprising entity geometry information describing a geometry of a corporeal entity to be considered in a medical procedure; b) acquiring imaging device operability data comprising imaging device operability information describing a mode of operation of the medical imaging device; c) determining, based on the entity geometry data and the imaging device operability data, operating parameter data comprising operating parameter information describing a value of at least one operating parameter of the medical imaging device.

First claim

The invention claimed is:

1. A data processing method for determining at least one operating parameter of a medical imaging device having a gantry, the method being executed by a computer and comprising:
a) acquiring entity geometry data regarding a microscope comprising entity geometry information describing a geometry of the microscope having an adjustable focal plane and being a corporeal entity to be considered in a medical procedure, the focal plane having a tilt angle relative to an associated patient's body, wherein the entity geometry data has been acquired by tracking the microscope and the medical imaging device with a navigation system, wherein the entity geometry data is associated with
treatment plan data comprising treatment plan information describing at least one of a geometry of a target region or a critical region, an instrument trajectory, a dose value to be administered to the associated patient's body, a pharmaceutical to be administered to the associated patient's body and a ray geometry to be emitted by the medical imaging device;
b) acquiring imaging device operability data comprising imaging device operability information describing a mode of operation of the medical imaging device;
c) determining, based on the entity geometry data and the imaging device operability data, operating parameter data comprising operating parameter information describing a value of at least one operating parameter of the medical imaging device, the at least one operating parameter including a tilt angle of the gantry relative to the associated patient's body, the tilt angle of the gantry relative to the associated patient's body being the same as the tilt angle of the focal plane relative to the associated patient's body; and
d) controlling the medical imaging device to adjust the tilt angle of the gantry to be the same as the tilt angle of the focal plane relative to the associated patient's body.

2. The method according to claim 1 , wherein the medical imaging device is a scanner for at least one of X-ray tomography, magnetic resonance tomography, conventional X-ray imaging and positron-emission tomography.

3. The method according to claim 1 , wherein the operating parameter further includes at least one of X-ray tube voltage, X-ray tube current, pitch, surface dose or effective dose to be applied, position and/or size of scan volume, layer thickness of a tomography slice, distance between tomography slices, filter kernel, and windowing.

4. The method according to claim 1 , further comprising issuing a signal comprising information that indicates whether the medical imaging device has been controlled according to the value of the determined operating parameter.

5. A non-transitory computer readable storage medium storing computer program for determining at least one operating parameter of a medical imaging device having a gantry, which, when running on a computer or when loaded onto a computer, causes the computer to:
a) acquire entity geometry data regarding a microscope comprising entity geometry information describing a geometry of the microscope having an adjustable focal plane and being a corporeal entity to be considered in a medical procedure, the focal plane having a tilt angle relative to an associated patient's body, wherein the entity geometry data has been acquired by tracking the microscope and the medical imaging device with a navigation system, wherein the entity geometry data is associated with
treatment plan data comprising treatment plan information describing at least one of a geometry of a target region or a critical region, an instrument trajectory, a dose value to be administered to the associated patient's body, a pharmaceutical to be administered to the associated patient's body and a ray geometry to be emitted by a medical imaging device;
b) acquire imaging device operability data comprising imaging device operability information describing a mode of operation of the medical imaging device;
c) determine, based on the entity geometry data and the imaging device operability data, operating parameter data comprising operating parameter information describing a value of at least one operating parameter of the medical imaging device, the at least one operating parameter including a tilt angle of the gantry relative to the associated patient's body, the tilt angle of the gantry relative to the associated patient's body being the same as the tilt angle of the focal plane relative to the associated patient's body; and
d) control the medical imaging device to adjust the tilt angle of the gantry to be the same as the tilt angle of the focal plane relative to the associated patient's body.

6. A navigation system for computer-assisted surgery, comprising:
the computer according to claim 5 , the computer being configured to process the entity geometry data, the imaging device operability data, and the operating parameter data;
a detection device for detecting the position of at least one of the medical imaging device, an anatomical body part and the microscope, the detection device configured to provide the entity geometry data;
a data interface for receiving the entity geometry data from the detection device and for supplying the entity geometry data to the computer; and
a user interface for receiving data from the computer in order to provide information to a user, wherein the received data is generated by the computer on the basis of the results of the processing performed by the computer.

7. A computer comprising the non-transitory computer readable storage medium according to claim 5 .
