Latest Patents

Doyoung Chang holds a patent for a method titled "Geometric biopsy plan optimization." This invention focuses on calculating the tumor detection probability of a biopsy plan and generating a 3D biopsy plan that maximizes this probability. The method involves modeling a capsule-shaped volume to represent the area that a biopsy core may sample. An optimization technique is employed to create a 3D biopsy plan that maximizes the likelihood of tumor detection based on predefined biopsy core numbers and lengths. Additionally, the invention calculates the risk of detecting insignificant tumors and the probability of false negative results. It also provides a method to determine the number and length of biopsy cores required for individual patients, balancing the probabilities of detecting significant versus insignificant tumors based on prostate size and shape.
