Coherent Optical Emission Imaging


Stanford Reference:

09-043


Abstract


Stanford researchers have developed a novel method for optical processing of scintillation signals to form an emission image in PET, SPECT, or Gamma Ray imaging. These types of images are used to form non-invasive images of radio-active distributions for medical imaging. In all these medical imaging systems, the processing of signals is done electrically. Previously, this team of researchers developed an electro-optical amplifier that converts a fast scintillation detector signal into an amplified, coherent light source that is confined to a fiber (S07-047). Due to the widespread availability of inexpensive, miniature semiconductor lasers and fibers for telecommunications, every readout channel can be encoded electro-optically. This enables the subsequent signal processing, for example “coincidence logic” in the case of PET, to be performed all optically, rather than electronically, which has potential significant speed, cost, space, and power savings.

Applications


  • PET, SPECT, Gamma Ray Imaging, or scintillation detection in general

Advantages


  • All optical processing (e.g., logic) has significant performance, cost, space, and power savings over huge arrays of electronic processing
  • Reduces cost and complexity of high resolution emission imaging system (e.g., expensive time-of-flight PET systems and expensive readout electronics for SPECT)
  • Novel method of using optical components for higher resolution, higher sensitivity, and better quantification for all types of emission imaging
