Abstract
A method for multi-modality imaging is provided. The method includes receiving a first signal from a detector operating in a first imaging modality, and receiving a second signal from the detector operating in a second imaging modality, wherein the first and second signals are received sequentially.
Claims22
A method for multi-modality imaging with a cadmium zinc telluride (CZT) detector array, the method comprising:
- receiving a first signal during a first portion of an imaging scan from the entire cadmium zinc telluride (CZT) detector array operating in a first imaging modality;
- receiving a second signal during a second portion of the imaging scan from the entire CZT detector array operating in a second imaging modality;
- wherein the first and second signals are received sequentially during respective portions of the imaging scan;
- wherein the imaging scan is performed sequentially by completing a first single view angle using the first imaging modality, then completing a second single view angle using the second imaging modality, and then alternating the modalities at each successive single view angle until the imaging scan is completed;
- processing emission photons impinging on the entire CZT detector array in the first imaging modality and processing transmission photons impinging on the entire CZT detector array in the second imaging modality.

A method of performing an image scan having at least a first scan portion and a second scan portion with a CZT detector array, said method comprising:
- performing the first scan portion using a first modality with the entire CZT detector array;
- performing the second scan portion using a second modality with the entire CZT detector array;
- wherein the first scan portion and second scan portion are performed alternately during the scan;
- wherein the image scan is performed sequentially by completing a first single view angle using the first modality, then completing a second single view angle using the second modality, and then alternating the modalities at each successive single view angle until the image scan is completed;
- using at least one processor in a current mode to process x-ray image data;
- and
- using at least one processor in a discriminate mode to process gamma ray image data wherein the processor in the discriminate mode is configured to determine an energy of each gamma ray.

An imaging system comprising:
- a CZT detector array comprising a plurality of detectors configured to detect emission photons during a first portion of a scan in a first imaging modality with the entire detector array and transmission photons during a second portion of the scan in a second imaging modality with the entire detector array;
- a first processor coupled to said detector array, said first processor configured to process emission photon data;
- a second processor coupled to said detector array, said second processor configured to process transmission photon data;
- wherein processing emission photon data from said CZT detector array and processing transmission photon data from said CZT detector array is performed sequentially during the scan;
- and wherein the scan is performed sequentially by completing a first single view angle using the first imaging modality, then completing a second single view angle using the second imaging modality, and then alternating the modalities at each successive single view angle until the scan is completed.

A controller for controlling a medical imaging system with a CZT detector array comprising:
- a first processor configured to process emission photon data received from the entire CZT detector array during a first portion of a scan in a first imaging modality;
- a second processor configured to process transmission photon data received from the entire CZT detector array during a second portion of the scan in a second imaging modality;
- wherein processing emission photon data from all detectors participating in the scan and processing transmission photon data from all detectors participating in the scan is performed sequentially during the scan;
- and wherein the scan is performed sequentially by completing a first single view angle using the first imaging modality, then completing a second single view angle using the second imaging modality, and then alternating the modalities at each successive view angle until the scan is completed.
