1. A method for selecting and recording biopsy sites in a body organ comprising: a) obtaining a three-dimensional volume of backscattered Ultrasound data grid of a three-dimensional region of the organ; b) obtaining a two-dimensional matrix of Ultrasound data of a two-dimensional sub-region of said organ; c) positioning the two-dimensional matrix of Ultrasound data in the three-dimensional volume of backscattered Ultrasound data grid obtained in step (a); and d) indicating in the three-dimensional volume of backscattered Ultrasound data grid and/or in the two-dimensional matrix of Ultrasound data any sites at which biopsies were obtained.
