Abstract

Various methods and systems are provided for a detector head for an imaging system. The detector head comprises a detector module comprising at least one detector element for detecting radiation and detector electronics, and a shaft to which the detector module is coupled, the detector module configured to rotate more than 360 degrees about the shaft in at least one direction.

First claim

The invention claimed is:

1. A detector head for an imaging system, comprising:
a detector module comprising at least one detector element for detecting radiation and detector electronics; and
a shaft to which the detector module is coupled, the detector module configured to rotate more than 360 degrees about the shaft in at least one direction, wherein the detector head is configured to accelerate a rotation of the detector module about the shaft when the detector module is oriented away from a subject during a focused scanning mode.

2. The detector head of claim 1 , wherein a voltage is conducted through the shaft and applied to the detector module.

3. The detector head of claim 1 , wherein the detector module includes at least one inductive coil, the inductive coil configured to receive a voltage via inductive coupling.

4. The detector head of claim 1 , wherein the detector module includes a transceiver, the transceiver configured to transmit imaging data to a data acquisition system via a short-range wireless protocol.

5. The detector head of claim 1 , wherein the detector head further includes at least one fan to circulate air around the detector module.

6. The detector head of claim 1 , wherein a relative encoder is attached to the shaft.

7. The detector head of claim 6 , wherein the detector module transmits detector orientation data from the relative encoder to a detector controller via a short-range wireless protocol, and wherein the relative encoder includes a home marker positioned to indicate when the detector module is oriented away from a subject.

8. The detector head of claim 1 , wherein the detector head is a first detector head included in a first imaging detector configured to be coupled to a gantry via an arm, and further comprising one or more second imaging detectors coupled to the gantry, each of the one or more second imaging detectors comprising a respective detector head configured to rotate greater than 360 degrees about a respective shaft.

9. The detector head of claim 1 , further comprising an extruded structural lead shield enclosing the detector head.

10. The detector head of claim 1 , wherein the detector head is enclosed in a cast epoxy with tungsten powder.

11. A system, comprising:
a detector head comprising:
a rotational motor configured to rotate a shaft, a first end of the shaft attached to a first ball bearing and a second end of the shaft attached to a second ball bearing; and
a detector module attached to the shaft, the detector module including at least one detector element for detecting radiation and configured to wirelessly receive electrical energy; and

an arm, the detector head coupled to the arm, wherein the detector head is configured to rotate greater than 360 degrees about an axis of rotation defined by the shaft.

12. A system, comprising:
a detector head comprising:
a rotational motor configured to rotate a shaft, a first end of the shaft attached to a first ball bearing and a second end of the shaft attached to a second ball bearing; and
a detector module attached to the shaft, the detector module including at least one detector element for detecting radiation and configured to wirelessly receive electrical energy, wherein a voltage is applied to the first ball bearing, and the detector module wirelessly receives electrical energy by the detector module receiving the voltage via the shaft.

13. The system of claim 12 , wherein the second ball bearing is connected to ground.

14. The system of claim 11 , further comprising a first inductive coil attached to the detector module and a second inductive coil fixed to the detector head and coaxially positioned about the first inductive coil to induce a voltage in the first inductive coil.

15. The system of claim 11 , further comprising a data acquisition system, and wherein the detector module transmits imaging data to the data acquisition system via a short-range wireless protocol.

16. The system of claim 12 , further comprising an arm, the detector head coupled to the arm, and wherein the detector head is configured to rotate greater than 360 degrees about an axis of rotation defined by the shaft.
