Abstract

The invention provides a task state functional magnetic resonance scanning data denoising method, and a device thereof, electronic equipment and a storage medium, and the method comprises the steps: determining N non-neuron voxel scanning data in task state functional magnetic resonance scanning data corresponding to the execution of a target task by a subject according to brain structure magnetic resonance scanning data of the subject; performing sparse learning based on the N non-neuron voxels to obtain a noise dictionary; for voxels in the task state functional magnetic resonance scanning data, using each noise dictionary element as a regression parameter, performing linear regression on a BOLD signal sequence corresponding to the voxels, and obtaining a noise sparse coefficient; and generating de-noised task state functional magnetic resonance scanning data based on the noise sparse coefficient corresponding to each voxel in the task state functional magnetic resonance scanning data and each noise dictionary element. The noise in the task state functional magnetic resonance scanning data can be removed in a targeted manner.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a method, device, equipment and medium for denoising data of task-state functional magnetic resonance scans. Background technique [0002] fMRI (functional magnetic resonance imaging, functional magnetic resonance imaging) is a non-invasive neuroimaging method, the principle is to use magnetic resonance imaging to measure hemodynamic changes caused by neuronal activity. The task-state fMRI refers to the measurement of the neuron response to the stimulus given a pre-designed task stimulus, such as allowing the subject to observe a picture at a fixed time. In recent decades, task-based functional magnetic resonance imaging (task-based functional resonance imaging, task fMRI) has played an important role in understanding the cognitive process of the human brain. It is an ideal choice for neuroscience research, clinical research, and a powerful tool for clinical interventi...
