Problems solved by technology

In addition, simultaneous CT-SPECT systems have been proposed (typically using CZT or CdTe) although issues arise due to generally differing collimation and flux rate requirements.

Embodiment Construction

[0014]The invention provides novel Compton camera detector designs and systems for enhanced radiation imaging including Compton and nuclear medicine imaging, PET imaging and x-ray CT imaging. The invention also provides integrated detector systems based on Compton camera designs. In one aspect, the invention provides integrated non-coincidence Compton-PET detector imaging systems. In another aspect, the invention provides integrated coincidence Compton-PET detector imaging systems. In yet another aspect, the invention provides limited integrated CT-Compton-PET detector imaging systems. In still another aspect, the invention provides integrated non-coincidence CT-Compton-PET detector imaging systems. In another aspect, the invention provides integrated coincidence CT-Compton-PET detector imaging systems. Since the integrated nature of these Compton camera detector design implementations is readily apparent the term “integrated” will frequently be omitted when referring to them. There...

Abstract

The invention provides novel Compton camera detector designs and systems for enhanced radiographic imaging with integrated detector systems which incorporate Compton and nuclear medicine imaging, PET imaging and x-ray CT imaging capabilities. Compton camera detector designs employ one or more layers of detector modules comprised of edge-on or face-on detectors or a combination of edge-on and face-on detectors which may employ gas, scintillator, semiconductor, low temperature (such as Ge and superconductor) and structured detectors. Detectors may implement tracking capabilities and may operate in a non-coincidence or coincidence detection mode.

Description

[0001]This application is a continuation-in-part of Application No. 61 / 689,139 filed on May 31, 2012 and Application No. 61 / 690,348 filed on Jun. 25, 2012.FIELD OF THE INVENTION[0002]This invention provides novel implementations of Compton camera detector systems that can be employed as novel integrated Compton-PET detector systems and CT-Compton-PET detector systems for diagnostic medical and small animal imaging (x-ray CT, nuclear medicine, PET) as well as radiation therapy, dental, industrial, Homeland Security and scientific radiation imaging.BACKGROUND OF THE INVENTION[0003]The combining of imaging modalities to offer increased functionality has produced a number of useful imaging systems, particularly in medical diagnostic and small animal imaging. For example, Gamma ray PET detector systems are frequently sold with x-ray CT detector systems (although the PET and CT detector systems are physically separate and therefore do not share detectors or a common imaging space). A nota...
