Abstract:
1. A method for spatially localizing a lesion for the purposes of radiation treatment planning in a treatment planning session comprising the steps of: a) generating, in the treatment planning session, one or more diagnostic images of said lesion in an absolute coordinate reference system using a non-ultrasound diagnostic imaging device; b) assigning said lesion on said diagnostic image a first set of three-dimensional coordinates in the absolute coordinate reference system; c) generating, in the treatment planning session, one or more ultrasound images of said lesion in the absolute coordinate reference system using an ultrasound device; d) assigning said lesion on said ultrasound images a second set of three-dimensional coordinates in said absolute coordinate reference system; e) fusing said diagnostic image and said ultrasound images in registration using the first and second sets of three-dimensional coordinates of the absolute coordinate reference system so as to obtain an enhanced image of the lesion; and f) developing a radiation treatment plan based, at least in part, on the fused images.
