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.

Claims (61)

1. An imaging system comprising:

a scanner;

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; and

a drive bar for controlling operation of the plurality of wheels of the gross movement mechanism;

wherein the drive bar comprises a left side and a right side;

wherein the drive bar is configured to detect the following motions of the drive bar: left side forward, left side back, left side up, left side down, right side forward, right side back, right side up and right side down; and

further wherein the drive bar is configured such that:

(i) when the right side of the drive bar and the left side of the drive bar are both pressed forwardly, the plurality of wheels of the gross movement mechanism move the imaging system forwardly;

(ii) when the right side of the drive bar and the left side of the drive bar are both pulled rearwardly, the plurality of wheels of the gross movement mechanism move the imaging system rearwardly;

(iii) when the right side of the drive bar is pressed forwardly and the left side of the drive bar is pulled rearwardly, the plurality of wheels of the gross movement mechanism rotate the imaging system to the left;

(iv) when the right side of the drive bar is pulled rearwardly and the left side of the drive bar is pushed forwardly, the plurality of wheels of the gross movement mechanism rotate the imaging system to the right;

(v) when the right side of the drive bar is lifted upwardly and the left side of the drive bar is pushed downwardly, the plurality of wheels of the gross movement mechanism move the imaging system laterally to the left; and

(vi) when the right side of the drive bar is pushed downwardly and the left side of the drive bar is pulled upwardly, the plurality of wheels of the gross movement mechanism move the imaging system laterally to the right.

2. An imaging system according to claim 1 wherein the wheels of the gross movement mechanism comprise a plurality of mecanum wheels.

3. An imaging system according to claim 2 wherein the wheels of the gross movement mechanism comprise four mecanum wheels.

4. An imaging system according to claim 1 wherein the wheels of the gross movement mechanism comprise steerable powered castors.

5. An imaging system according to claim 1 further comprising a collision sensor system for detecting the presence of an obstacle in the drive path of the imaging system or alongside the imaging system.

6. An imaging system according to claim 5 wherein, when the collision sensor system detects the presence of an obstacle in the drive path of the imaging system or alongside the imaging system, the collision sensor system responds by causing at least one of the following actions: sounding an alarm and automatically decreasing the speed of the gross movement mechanism.

7. An imaging system according to claim 1 wherein the scanner comprises a CT machine.

8. A method for scanning an object, the method comprising:

providing an imaging system, the imaging system comprising:
