Table 1 MRI system affecting PET
From: PET/MRI: a frontier in era of complementary hybrid imaging
Components of MRI | Effect on PET | Consequences | Resolution |
|---|---|---|---|
Static magnetic field (B0) | Influences the ray of electron flow in read out. | Lower gain factor. | Substitute the Photomultiplier with Solid State Photo Detector (SSPD) such as SiPM or APD. |
Gradient magnetic field (B1) | Heats up the equipment leading to vibrations. | Induction of eddy currents and mechanical vibrations. | Restructuring of electronic components. Fixing temperature control device. |
RF Interference | Introduces noise signal. | Due to magnetic induction, introduces eddy current. Produces heating effect. | Introducing RF shield around the coil. |
