Abstract

The invention relates to a scanning bed, an SAR factor monitoring method and device, a medium and a magnetic resonance system. The scanning bed comprises a scanning bed body, a metal detector and a pressure sensor, wherein the metal detector and the pressure sensor are both arranged on the scanning bed body, the metal detector is used for detecting whether a patient on the scanning bed body wears metal or not; and the pressure sensor is used for measuring the weight of a patient on the scanning bed body. The problems that the weight of a patient cannot be accurately obtained and whether the patient wears a metal object cannot be judged at present are solved.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance scanning, in particular to a scanning bed, a SAR factor monitoring method, equipment, media and a magnetic resonance system. Background technique [0002] At present, when a patient undergoes an MRI scan, the SAR (Specific Absorption Rate) factor needs to be monitored in real time, so as to prevent the patient from being harmed due to an excessive SAR value. [0003] Generally, manufacturers calculate, predict and monitor the SAR factor of patients based on their gender, height and weight at the time of registration, but the data at the time of registration may deviate from the data at the time of actual measurement, resulting in errors in the calculation of SAR factors, and further Patient injury may result. In addition, before the MRI scan, in order to avoid deviations and potential risks in the scan results, patients should be prohibited from wearing metal objects. Occurs underrepo...
