Abstract

A gantry scanner system includes a radiation source, a plurality of detectors and a support frame supporting the detectors. The support frame includes an elongate support member arranged to support the detectors, cable support means arranged to support power cables or signal cables connected to the detectors, and cover means arranged to cover the support member, the cable support means and the detectors.

Claims

1. A gantry scanner system comprising a radiation source, a plurality of detectors and a support frame supporting the detectors, wherein the support frame includes an elongate support member arranged to support the detectors, cable support means arranged to support power cables or signal cables connected to the detectors, and cover means arranged to cover the support member, the cable support means and the detectors.

2. A system according to claim 1 wherein the support member is of a constant cross section along its length.

3. A system according to claim 2 wherein the support member comprises a central web and two side sections.

4. A system according to claim 3 wherein the detectors are mounted within a cavity formed by the central web and the side sections.

5. A system according to claim 4 wherein radiation absorbing means are mounted on the opposite side of the central web to the detectors.

6. A system according to claim 3 wherein the support member is of an H-shaped cross-section.

7. A system according to claim 3 wherein the cable support means is located on the outer side of at least one of the side sections.

8. A system according to claim 7 wherein the cable support means comprises a cable support tube mounted on the support section by means of a plurality of tube support brackets.

9. A system according to claim 1 wherein the cover means comprises a plurality of removable cover sections which can each be removed to allow access to the detectors.

10. A system according to claim 1 wherein the support frame comprises a plurality of said support members connected together.

11. A system according to claim 10 wherein the support frame comprises two of said support members connected together at right angles to each other to form a vertical side and a horizontal top of the frame, and a further vertical section connecting one of the support members to a radiation source module.

12. A system according to claim 11 wherein the radiation source module and one of the support members are movably supported by support means and guide means are provided to guide the gantry to move along a predetermined path.

13. A system according to claim 1 further including a control system and power storage means arranged to be connectable to a power supply so that it can be recharged.

14. A gantry scanning system comprising a gantry, a radiation source, radiation detectors, a control system and a rechargeable power storage means mounted on the gantry, wherein the power storage means is arranged to be connectable to a power supply so that it can be recharged.

15. A system according to claim 14 further comprising guide means defining a path along which the gantry can move, wherein the power storage means is arranged to be connectable to the power supply only when it is in one or more recharging positions on the path.

16. A system according to any of claims 15 wherein recharging means are provided at each end of the path so that the power storage means can be recharged in each of two recharging positions.

17. A system according to any of claims 14 wherein the control system is arranged to transmit scan data, obtained by the scanner, wirelessly to a remote station for analysis.

18. A system according to claim 17 wherein the remote station includes display means arranged to display an image generated from the scan data.

19. A system according to any of claim 17 wherein the control system is arranged to receive control instructions wirelessly from the remote control station.
