Abstract

The invention discloses a noise prediction system and method. The method comprises the steps of obtaining a gradient waveform and a corresponding sound pressure waveform in a magnetic resonance scanning process; preprocessing the gradient waveform and the corresponding sound pressure waveform; performing machine learning model training on the preprocessed gradient waveform and the corresponding sound pressure waveform to obtain a response relationship between the gradient waveform and noise; and carrying out noise prediction on gradient waveforms of different sequences by adopting the responserelationship.

Description

technical field [0001] The invention relates to the field of medical technology, and in particular to a noise prediction system and method. Background technique [0002] As a widely used non-invasive imaging method, magnetic resonance imaging (Magnetic Resonance Imaging, MRI) has an irreplaceable position in clinical diagnosis and scientific research. However, the noise generated by the gradient coil during scanning can reach more than 100dBA, which will bring serious health and safety risks to patients, especially infants. Overexposure to noisy environments in adults can cause hearing loss, induce autonomic nervous system stimulation, and possibly lead to hypertension and cardiovascular disease. The noisy environment is also one of the factors that lead to the loss of high-frequency hearing in fetuses, premature birth and intrauterine growth retardation. [0003] Noise during an MRI scan is mainly generated by mechanical vibrations of gradient coils and other mechanical s...
