Provided herein are systems and methods (i.e., utilities) that are directed to correcting misalignments or offsets between a series or sequence of medical images. The utility corrects offsets between a series of medical images obtained where an imaging device (e.g., ultrasound probe) is supported by a positioning mechanism where there is misalignment between an imaging axis or other reference point of the imaging device and the axis of movement of the positioning device. The determination of this offset between these axis allows for calculating a transformation that allows for placing each of the series images into a common frame of reference.

Calibration for 3D reconstruction of medical images from a sequence of 2D images

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.
