1. A method of manipulating a 3-dimensional medical dataset comprising:
- translating a body part;
receiving camera data of said translating the body part from a camera system;
determining with a processor a translation distance and a translation direction from the camera data based on at least one of feature tracking and a focus depth of the camera system;
translating a crop plane in the 3-dimensional medical dataset based on the translation distance and the translation direction;
cropping the 3-dimensional medical dataset at the location of the crop plane after said translating the crop plane; and
displaying the cropped 3-dimensional medical dataset using volume rendering.

Abstract
A method and gesture-based control system for manipulating a 3-dimensional medical dataset include translating a body part, detecting the translation of the body part with a camera system. The method and system include translating a crop plane in the 3-dimensional medical dataset based on the translating the body part. The method and system include cropping the 3-dimensional medical dataset at the location of the crop plane after translating the crop plane and displaying the cropped 3-dimensional medical dataset using volume rendering.
