Title:
INTEGRATED PET/MRI APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/056504
Kind Code:
A1
Abstract:
In the integrated PET/MRI apparatus provided with an RF coil for MRI and multiple PET detectors in the measurement port of the MRI apparatus, the PET detectors are disposed with spaces therebetween and at least the transmitting coil elements of the MRI RF coil are disposed between adjacent PET detectors. Here, the PET detectors are disposed in the circumferential direction of the measurement port with spaces therebetween and the transmitting coil elements are disposed in the axial direction of the measurement port. Alternatively, at least some of the PET detectors are disposed in the axial direction of the measurement port with spaces therebetween and the transmitting coil elements are disposed between adjacent PET detectors. The PET detectors can be DOI-type detectors capable of detecting position in the depth direction.
