    摘要: The present invention is directed to a method for calculating tumor detection probability of a biopsy plan and for generating a 3D biopsy plan that maximizes tumor detection probability. A capsule shaped volume is modeled to represent the volume that a biopsy core may sample. An optimization method is used to generate a 3D biopsy plan that maximizes probability of tumor detection for predefined biopsy core numbers and length. Risk of detecting insignificant tumors, also determined by size, and probability of a false negative result is automatically calculated. The present invention also includes a method to determine number and length of biopsy cores required for individual patients determined by the balance of the insignificant/significant probability of detection, prostate size and shape, based upon the previously explained 3D biopsy plan generation method.

    摘要: A robot-assisted approach for transrectal ultrasound (TRUS) guided prostate biopsy includes a hands-free probe manipulator that moves the probe with the same 4 degrees-of-freedom (DoF) that are used manually. Transrectal prostate biopsy is taken one step further, with an actuated TRUS manipulation arm. The robot of the present invention enables the performance of hands-free, skill-independent prostate biopsy. Methods to minimize the deformation of the prostate caused by the probe at 3D imaging and needle targeting are included to reduce biopsy targeting errors. The present invention also includes a prostate coordinate system (PCS). The PCS helps defining a systematic biopsy plan without the need for prostate segmentation. A novel method to define an SB plan is included for 3D imaging, biopsy planning, robot control, and navigation.
