Mobile anatomical imaging system with improved movement system

Abstract

A new and improved anatomical imaging system which includes a new and improved movement system, wherein the movement system comprises an omnidirectional powered drive unit and wherein the movement system can substantially eliminate lateral walk (or drift) over the complete stroke of a scan, even when the floor includes substantial irregularities, whereby to improve the accuracy of the scan results and avoid unintentional engagement of the anatomical imaging system with the bed or gurney which is supporting the patient.

1 . An imaging system comprising:
 a scanner; and   a transport mechanism mounted to the base of the scanner, wherein the transport mechanism comprises:
 a gross movement mechanism for transporting the scanner relatively quickly across room distances; and 
 a fine movement mechanism for moving the scanner precisely, relative to the object being scanned, during scanning; and 
 apparatus for selectively causing the gross movement mechanism or the fine movement mechanism to engage the floor; 
 wherein the gross movement mechanism comprises a plurality of wheels configured to provide omnidirectional drive; and 
 wherein the fine movement mechanism comprises a plurality of independently powered wheels.
