Method and system for controlled scanning, imaging, and/or therapy

Abstract

A method and system for three dimensional scanning, imaging and/or therapy are provided. In accordance with one aspect, an exemplary method and system are configured to facilitate controlled scanning within one-degree of freedom. For example, an exemplary method and system can enable multiple two-dimensional image planes to be collected in a manner to provide an accurate and computationally efficient three-dimensional image reconstruction while providing the user with a user-friendly mechanism for acquiring three-dimensional images. In accordance with an exemplary embodiment, the positioning system comprises a guide assembly configured to provide pure rectilinear or rotational motion of the probe during scanning operation, and a position sensing system configured to detect the direction and position of the probe during scanning.

1 . A method for facilitating controlled scanning of an imaging probe relative to a region of interest, said method comprising:
 scanning a region of interest with a hand-held imaging probe;   restricting movement of said imaging probe through use of a guide assembly to rotate around an axis which is substantially perpendicular to a surface of the region of interest; and   determining position of said imaging probe within said guide assembly through use of a position sensing system to facilitate three-dimensional reconstruction of images by a control system.   
     
     
         2 . The method according to  claim 1 , wherein restricting movement comprises coupling a guide member to said imaging probe. 
     
     
         3 . The method according to  claim 1 , wherein restricting movement comprises controlling movement in a rotational manner.
