Embodiment Construction

[0033] Embodiments of the present invention are preferably used on combined MR-PET devices. The combined device has the advantage that MR data and PET data can be acquired concentrically at the same time. This makes it possible to precisely define an examination volume within a region of interest using data from a first modality (PET) and to use this information in another modality (eg magnetic resonance). Although it is possible to transmit the volume information of the region of interest from an external PET system to the MR system, this increases the outlay for registering the data. In general, all data that can be determined with magnetic resonance or other imaging methods can be determined on selected regions of interest in the PET data set. For example, instead of spectroscopic data, fMRI data, diffusion maps, T1- or T2-weighted images or quantitative parameter maps can also be acquired in the region of interest by means of magnetic resonance examinations. Likewise, co...

Abstract

A device for detecting signals is disclosed. In at least one embodiment, the device includes at least four detector elements for receiving the signals and converting them into useful signals, each being connected via at least two lines to at least one signal processing unit. Each detector element includes a polarity reversal unit by which polarity reversal of the useful signal of the respective detector element can be performed. The signal polarity reversal logic is unambiguously spatially direction-dependent within the detector array. An advantage of the device of at least one embodiment is that for signals to be received simultaneously by way of two detector elements, the detector elements involved become unambiguously identifiable by the polarity reversal of the useful signal.

Description

technical field [0001] The invention relates to a device for receiving signals, having at least four detector elements for receiving signals and converting them into useful signals, which are each connected via at least two lines to at least one signal processing unit. Background technique [0002] In addition to magnetic resonance tomography (MR), positron emission tomography (PET) is increasingly being used for medical diagnosis. MR is an imaging method used to visualize structures and cross-sections inside the body, while PET can visualize and quantify metabolic activity in the body. [0003] PET utilizes the unique characteristics of positron radiation and positron annihilation to quantitatively determine the function of organs or cellular regions. Here, a radiopharmaceutical labeled with a radionuclide is administered to the patient prior to the examination. In the case of radionuclide decay, a positron is released which, after a short distance, interacts with an elec...
