3D imaging News
Quantum Sensor Could Increase Quality and Speed of MRI Scans
COPENHAGEN, May 21, 2024 — Although MRI scanners provide 3D images of exceptional quality, they require frequent calibration and are limited in the types of scans they can perform. Their strong magnetic field can cause fluctuations that lead to errors in the scans. Due to the instability of the magnetic field, scanning methods like spiral sequences are not feasible. Electrical sensors that are connected to metal cables are unsuitable for stabilizing MRI scanners because they can disrupt the magnetic field. A
