The invention provides a magnetic
resonance image based cerebral micro-bleeding computer auxiliary detection
system and belongs to the medical image computer auxiliary detection field. The magnetic
resonance image based cerebral micro-bleeding computer auxiliary detection
system comprises five portions of an image import module, an image preprocessing module, a characteristic extraction module, an automatic detection module and a cerebral micro-bleeding automatic detection report output module. According to the magnetic
resonance image based cerebral micro-bleeding computer auxiliary detection
system, the characteristics of T1, T2 and GRET2* images are comprehensively considered, the
prior information of the cerebral micro-bleeding of different cerebral positions is obtained through a cerebral micro-bleeding focus prior distribution probability template, and a
random forest classifier is combined to perform the automatic detection on the cerebral micro-bleeding focus; the system sensitivity is 0.890 and every case comprises 1.530 false positive focuses in average through a test; the magnetic resonance image based cerebral micro-bleeding computer auxiliary detection system is objective and high in
repeatability in comparison with the traditional manual
discriminant method and the magnetic resonance image based cerebral micro-bleeding computer auxiliary detection system is accurate and reliable in comparison with the existing computer auxiliary detection method; the operation is simple and convenient, the identification result of the cerebral micro-bleeding focus can be objectively provided, and meanwhile the abundant information is provided for the reference of doctors.
