Anatomical imaging system with a crawl drive
An imaging system for imaging an object, comprising a scanner; and a transport mechanism mounted to the base of the scanner, wherein the transport mechanism comprises a crawl drive for crawling along the floor supporting the imaging system so as to index the scanner relative to an object during scanning of the object.
1. An imaging system for imaging an object, comprising:
a scanner; and
a transport mechanism mounted to a base of the scanner, wherein the transport mechanism comprises a crawl drive for directly engaging a floor supporting the imaging system and crawling along the floor supporting the imaging system so as to index the scanner relative to an object during scanning of the object;
wherein the transport mechanism further comprises a gross movement mechanism for transporting the scanner relatively quickly across room distances;
wherein the gross movement mechanism comprises an actuator for: (i) extending portions of the gross movement mechanism below portions of the crawl drive drive whereby the scanner will be supported by portions of the gross movement mechanism; and (ii) retracting portions of the gross movement mechanism above portions of the crawl drive whereby the scanner will be supported by portions of the crawl drive.
2. An imaging system according to claim 1 wherein the crawl drive is configured to index the scanner relative to the object using discrete steps, whereby to enable slice scanning.
3. An imaging system according to claim 1 wherein the crawl drive is configured to index the scanner relative to the object using substantially continuous movement, whereby to enable helical scanning.
4. An imaging system according to claim 1 wherein the crawl drive comprises at least one centipede belt drive unit.
5. An imaging system according to claim 1 wherein the gross movement mechanism comprises at least one caster.
6. An imaging system according to claim 1 wherein the scanner comprises a CT machine.
7. An imaging system according to claim 1 wherein the object comprises a patient.
8. A method for scanning an object, the method comprising:
providing an imaging system for imaging an object, comprising:
a scanner; and
a transport mechanism mounted to a base of the scanner, wherein the transport mechanism comprises a crawl drive for directly engaging a floor supporting the imaging system and crawling along the floor supporting the imaging system so as to index the scanner relative to the object during scanning of the object;
wherein the transport mechanism further comprises a gross movement mechanism for transporting the scanner relatively quickly across room distances;
wherein the gross movement mechanism comprises an actuator for: (i) extending portions of the gross movement mechanism below portions of the crawl drive whereby the scanner will be supported by portions of the gross movement mechanism; and (ii) retracting portions of the gross movement mechanism above portions of the crawl drive whereby the scanner will be suppported by portions of the crawl drive; and
scanning the object while moving the scanner precisely relative to the object, using the crawl drive, during scanning.
9. A method according to claim 8 wherein the crawl drive is configured to index the scanner relative to the object using discrete steps, whereby to enable slice scanning.
10. A method according to claim 8 wherein the crawl drive is configured to index the scanner relative to the object using substantially continuous movement, whereby to enable helical scanning.
11. A method according to claim 8 wherein the crawl drive comprises at least one centipede belt drive unit.
12. A method according to claim 8 wherein the gross movement mechanism comprises at least one caster.
13. A method according to claim 8 wherein the scanner comprises a CT machine.
14. A method according to claim 8 wherein the object comprises a patient.
15. An imaging system for imaging an object, comprising:
a scanner; and
a transport mechanism mounted to a base of the scanner, wherein the transport mechanism comprises a crawl drive for directly engaging a floor supporting the imaging system and crawling along the floor supporting the imaging system so as to index the scanner relative to an object during scanning of the object;
wherein the crawl drive comprises at least one centipede belt drive unit.
16. A method for scanning an object, the method comprising:
providing an imaging system for imaging an object, comprising:
a scanner; and
a transport mechanism mounted to a base of the scanner, wherein the transport mechanism comprises a crawl drive for directly engaging a floor supporting the imaging system and crawling along the floor supporting the imaging system so as to index the scanner relative to the object during scanning of the object;
wherein the crawl drive comprises at least one centipede belt drive unit; and
scanning the object while moving the scanner precisely relative to the object, using the crawl drive, during scanning.
