摘要:
A method for data evaluation of first and second measured data records acquired substantially simultaneously with the aid of a combined medical examination device suitable for simultaneous and isocentric acquisition of first measured data, includes reconstructing a first image data record from the measured data of the at least one first measured data record, reconstructing a second image data record from the measured data of the at least one second measured data record, fusing the image data records as a function of registering the coordinate systems of the first measured data record and of the second measured data record to form a fusion image data record, and displaying and/or storing the fusion image data record.
摘要:
In a method and an apparatus for automatic determination of objects that attenuate high energy/penetrating radiation by magnetic resonance, the magnetic resonance apparatus scans and prepares MR images, and the MR images contain information about the T2 relaxation time constant. Subsequently, penetrating radiation-attenuating objects are determined in the MR images by means of the T2 relaxation time constant.

摘要:
MR image data relating to a volume section of an examination object is determined. Image data relating to this volume section is also captured by way of a true-to-original tomographic method. The MR image data is compared with the image data. Depending on the results of this comparison, either the MR image data is corrected such that the MR image data matches the image data as closely as possible, or parameters that are used during the capture of the MR image data are modified such that, when the MR image data of the predefined volume section is captured again using the modified parameters, the newly captured MR image data matches the image data as closely as possible.
摘要:
A method is disclosed for data evaluation of first and second measured data records acquired substantially simultaneously with the aid of a combined medical examination device suitable for simultaneous and isocentric acquisition of first measured data, specifically magnetic resonance or computed tomography measured data, and second nuclear medicine measured data, specifically PET measured data or SPECT measured data. In at least one embodiment, the method includes reconstructing a first image data record from the measured data of the at least one first measured data record, reconstructing a second image data record from the measured data of the at least one second measured data record, fusing the image data records as a function of registering the coordinate systems of the first measured data record and of the second measured data record to form a fusion image data record, and displaying and/or storing the fusion image data record.
摘要:
The disclosure relates to a method to prevent a permissible specific absorption rate being exceeded during a magnetic resonance examination and to an evaluation unit, a magnetic resonance device, and a computer program product. The method includes a first provisioning unit providing a permissible SAR to an evaluation unit. A second provisioning unit, which may be identical to the first provisioning unit, provides a scan protocol for the magnetic resonance examination to the evaluation unit. The evaluation unit checks the scan protocol for the permissible SAR. If this check reveals that the permissible SAR is not adhered to, the scan protocol is modified. In this case, the modification of the scan protocol entails the amendment of at least one scan parameter of the scan protocol. The amendment of the at least one scan parameter is performed in dependence on at least one preference parameter.
摘要:
Various embodiments relate to a method of attenuation correction of Positron Emission Tomography (PET) data based on Magnetic Resonance Tomography (MRT) data. A method of at least one embodiment further includes determining further data being indicative of an iterative cycle of a physiological observable of a patient and matching the PET data with the MRT data based on the further data.

摘要:
A method is disclosed for at least partly determining and/or adapting an attenuation map used for attenuation correction of Positron Emission Tomography image data sets in a combined Magnetic Resonance-Positron Emission Tomography device. In at least one embodiment of the method, at least one one-dimensional magnetic resonance data set of a patient is recorded along one imaging direction; the boundaries of at least one part of the body of the patient intersected by the imaging direction are determined from the one-dimensional magnetic resonance data set; and the attenuation map is determined and/or adapted at least partly as a function of the boundaries determined.
