Abstract
A hybrid tomograph that includes a chamber for examining an object, a TOF-PET tomograph and an MRI tomograph. The MRI tomograph has a magnet for producing a magnetic field and a receiving-transmitting coil. The TOF-PET tomograph has polymer scintillation strips to transmit scintillation photons outside the magnet of the MRI tomograph and outside the chamber of the hybrid TOF-PET/MRI tomograph. The polymer scintillation strips are arranged circumferentially inside the magnetic field produced by the magnet of the MRI tomograph. Photoelectric converters for converting light signals from the polymer scintillation strips to electrical signals are arranged outside the magnet of the MRI tomograph and outside the chamber of the hybrid TOF-PET/MRI tomograph.

A hybrid TOF-PET/MRI (Time-Of-Flight Positron Emission Tomography/Magnetic Resonance Imaging) tomograph comprising:
- a chamber for examining an object,
- an MRI tomograph comprising a magnet for producing a magnetic field and a receiving-transmitting coil, wherein the magnet surrounds the chamber for examining the object and defines a magnet-surrounded volume and
- a TOF-PET tomograph comprising polymer scintillation strips, wherein at least one of the polymer scintillation strips is arranged partially inside the magnet-surrounded volume and partially outside the magnet-surrounded volume, to transmit scintillation photons outside the magnet-surrounded volume and outside the chamber of the hybrid TOF-PET/MRI tomograph, the polymer scintillation strips being arranged circumferentially inside the magnetic field produced by the magnet of the MRI tomograph;
- and photoelectric converters for converting light signals from the polymer scintillation strips to electrical signals, wherein the photoelectric converters are arranged outside the magnet-surrounded volume and outside the chamber of the hybrid TOF-PET/MRI tomograph.
