PET-MRI device and manufacturing method thereof
First Claim
1. A PET-MRI device, comprising:
- a magnetic resonance imaging (MRI) machine comprising a solenoid coil and a magnetic-field correction coil, wherein the MRI machine has a cylindrical structure; and
a positron emission tomography (PET) machine comprising a PET image sensor, wherein unitary doughnut shaped PET image sensor electrodes are formed on ends of the PET image sensor which consists essentially of a single compound semiconductor, and the PET machine has a cylindrical structure,wherein the PET machine is formed in the MRI machine and is configured to have a direction of an electric field of the PET machine that is parallel to a direction of a static magnetic field (B0) of the MRI machine by arranging the PET image sensor electrodes parallel to each other and a normal line of an electrode surface of each PET image sensor electrode parallel to the direction of the static magnetic field (B0).
