DEVICE AND METHOD FOR DETECTING CEREBRAL MICROBLEEDS USING MAGNETIC RESONANCE IMAGES

摘要

Disclosed are a device and method for detecting cerebral microbleeds using magnetic resonance images. The disclosed device includes a preprocessing unit that normalizes an SWI image and a phase image, respectively, of the magnetic resonance images, and performs phase image conversion for inverting a code of the normalized phase image, a YOLO neural network module that receives a two-channel image in which the preprocessed SWI image and phase image are concatenated and detects a plurality of candidate regions for the cerebral microbleeds, and a cerebral microbleeds determination neural network module that receives patch images of candidate regions of the SWI image and phase image based on the plurality of candidate regions and determines whether the patch images of each candidate region are an image with a symptom of the cerebral microbleeds through a neural network operation. According to the disclosed device and method, it is possible to detect cerebral microbleeds with improved performance through magnetic resonance image preprocessing suitable for detecting the cerebral microbleeds using an artificial neural network.
