Embodiment Construction

[0022] Embodiments of the invention are preferably used in combined MR-PET devices. An advantage of the combined device is that MR data and PET data can be acquired concentrically. This enables the exact definition of the examination space in the region of interest with data from a first module (PET) and then use this information in another module (eg magnetic resonance). Although it is possible to transfer stereoscopic information of the region of interest from an external PET device to the MR device, it will increase the overhead of data registration. In general, all data that can be determined using magnetic resonance or other imaging methods can be determined on a region of interest selected from the PET data record. For example, fMR data, diffusion maps, T1- or T2-weighted images or quantified parameter maps can also be obtained by means of magnetic resonance examinations in the region of interest instead of spectroscopic data. Likewise, computed tomography methods (eg,...

Abstract

The invention relates to a detector arrangement with a plurality of detector units, to each of which a data processing unit is assigned. An embodiment of the detector arrangement includes a cooling system with cooling units which are thermoconductively connected to the detector units and / or data processing units for cooling. The cooling units are connected to a distribution unit by which a coolantmay be supplied to the cooling units in parallel.

Description

technical field [0001] The invention relates to a detector arrangement having a plurality of detection units, each corresponding to a data processing unit, the detector arrangement comprising a cooling system with cooling units, for cooling, these cooling units are connected with the detection unit and The data processing unit is thermally connected. Background technique [0002] In addition to magnetic resonance tomography (MR), positron emission tomography (PET) has also been more and more widely used in the field of medical diagnosis in recent years. If MR is an imaging method that displays internal structures and tomographic images, PET makes it possible to visualize and quantify metabolic activities in living bodies. [0003] PET exploits the unique properties of positron emitters and positron annihilation to quantitatively determine the function of an organ or cellular region. In this case, corresponding radiopharmaceuticals labeled with radionuclides are administere...
