Abstract
Systems and methods relating to placement of an ultrasound transducer for a procedure. In a non-limiting embodiment, a 3D environment including images of a body region of a patient, as well as images including a first virtual representation of an ablation needle at a first location and a second virtual representation of an ultrasound transducer at a second location is rendered on a display device. A determination may be made as to whether the first and second virtual representations collide at a first collision point. If so, at least one parameter associated with an orientation and/or position of the second virtual representation may be adjusted. A determination may then be made as to whether or not the first and second virtual representations still collide and, in response to determining that there is no collision, position data indicating the location of the second virtual representation after the adjustment, is stored.
