Abstract
The application discloses a kind of prostate puncture biopsy intelligent navigation method and system, first, multi-parameter MRI image data and transrectal ultrasound image data are registered and fused to obtain prostate three-dimensional contour, implement anatomical partition and suspicious lesion identification to gland, determine target lesion and systematic puncture area according to adjacent lesion PI-RADS score distribution analysis;Subsequently, key anatomical landmarks are extracted and gland signal layering marking mechanism is established to generate gland signal distribution map;Determine puncture condition suitable area by physiological parameter check, establish puncture safety channel in combination with target lesion space matching and signal distribution analysis;Finally, in safety channel, complete multi-point path planning and vessel nerve avoidance simulation, and output puncture planning scheme with risk level.The application realizes the full-link automatic planning from image fusion to puncture path output, and can provide safe and reliable preoperative decision reference for prostate puncture biopsy.
