1. A system for performing biopsy of a prostate comprising: an ultrasound wand comprising: a probe having a housing and a proximal end and a distal end, the housing further defining a straight channel, and the straight channel takes an oblique path through the probe, wherein the straight channel comprises a first opening on a first side of the probe and a second opening on a second side of the probe, wherein the oblique path of the straight channel extends between the first opening and the second opening, and wherein the oblique path is oblique relative to a longitudinal axis of the probe; a needle guide disposed oblique to the probe and adjacent to the straight channel; a lateral fire sensor positioned within the housing of the probe; a handle operatively coupled to the probe, such that the probe rotates about a longitudinal axis of the handle, wherein the handle includes a first motor to rotate the probe about the longitudinal axis of the handle; a straight biopsy needle configured for insertion obliquely through the straight channel and through the needle guide, such that the prostate can be biopsied; and, a second motor operatively coupled to the needle guide to pivot the biopsy needle within the straight channel.
