Abstract
NMR-PET scanner apparatus is provided wherein a PET detector is disposed within a magnetic imaging structure of an NMR device. The output of the PET detector is conveyed through light pipes to photodetectors which are shielded and disposed without the magnetic imaging structure of the NMR device to avoid interaction between the photodetectors and the magnetic field generated by the magnetic imaging structure of the NMR device.
Claims12
NMR-PET scanner apparatus comprising:
- means for establishing a substantially uniform magnetic field in a first direction through a defined volume;
- scintillation means disposed in said defined volume in a plane which is at least partially transverse to said first direction;
- photodetector means disposed at a location removed from said defined volume to reduce interaction with said uniform magnetic field;
- and
- means for establishing light communication between said scintillation means and said photodetector means to enable light pulses generated by said scintillation means to be transduced into electrical signals by said photodetector means.
