Abstract: Guided biopsy is a commonly used method to remove suspicious tissues from an internal organ for pathological tests so that malignancy can be established. Provided herein are systems and methods (i.e., utilities) that allow for automated application of one or more predefined biopsy target plans to an acquired medical image including without limitation, an ultrasound prostate image. Due to different shapes and sizes of prostates as well as orientation of prostate with respect to an ultrasound probe during image, acquisition a simple prostate model (e.g., ellipse) with a fixed plan may not be sufficient. Accordingly, it has been determined that a deformable shape model with integrated biopsy target locations/sites may be fit to a prostate image to provide improved automated biopsy targeting.

Abstract: An improved system and method (i.e. utility) for registration of medical images is provided. The utility registers a previously obtained volume (s) onto an ultrasound volume during an ultrasound procedure to produce a multimodal image. The multimodal image may be used to guide a medical procedure. In one arrangement, the multimodal image includes MRI information presented in the framework of a TRUS image during a TRUS procedure.

Abstract: A system and method (i.e, utility) are disclosed for positioning a needle in three-dimensions based on patient related statistics for extracting tissue during biopsy procedures. Aspects of the utility can be applied independently or serve as an aid to the urologist when regions of interest are hard to discern in an ultrasound image. Regions of interest that correspond to high cancer risk regions (e.g., statistically) are automatically superimposed on an ultrasound image of a patient in real time. Additionally a statistical map based on one or more demographic parameters of a patient and containing cancer probability locations are also automatically mapped on the ultrasound image in real time displaying potential cancer locations. Aspects of the system are also capable of displaying optimal needle placement positions based on statistical priors and will be able to accurately navigate the needle to that position for biopsy extraction and/or treatment.
