Resumen:
Un grupo de investigación español ha diseñado un dispositivo que permite la determinación de la secuencia de tiempo completa y las interacciones fotoeléctricas producidas por un solo rayo gamma incidente. Las imágenes de rayos gamma son una tecnología clave para el diseño de dispositivos médicos basados en tomografía computarizada de emisión monofotónica (SPECT) o tomografía por emisión de positrones (PET) y se aplican en diagnóstico médico y terapia, así como en dispositivos astrofísicos como telescopios de rayos gamma o incluso control de centrales nucleares. El grupo de investigación busca socios industriales interesados en implementar esta tecnología en dispositivos médicos o astrofísicos mediante acuerdos de licencia.

Details

Tittle:
Gamma ray Compton Time-of-Flight (TOF) detector
Summary:
A Spanish research group has designed a device to allow determination of the complete timing sequence of Compton and photoelectric interactions produced by a single incident gamma ray, so the contribution of scattered events inside the photoelectric peak coming from scatter at the crystal or the human body can be estimated and accurately corrected.
Industrial partners interested in implementing this techonology in medical or astrophysical devices are being sought for licence agreement.
Description:
Gamma ray imaging is a key techonology for the design of medical devices based on Nuclear imaging systems like Single-Photon Emission Computed Tomography (SPECT) or Positron Emission Tomography (PET) for the purpose of medical diagnosis or therapy, but also for astrophysical devices such as gamma ray telescopes or even nuclear power plant monitoring. All these devices are based on the determination of the impact position of gamma ray interactions due to Compton scattering. One of the major challenges of analyzing data from a combined Compton camera is the reconstruction of the parameters of each original gamma ray from the measured data. This is a handicap in current Nuclear Medicine devices.
Our device consists of a gamma ray Compton TOF camera system capable to obtain the 3D position and energy of the interactions (Compton and photoelectric) and their relative timing by means of accurate determination of the TOF for each interaction. The combination of geometrical design and high timing resolution of the system of the invention allow determination of the full temporal sequence of all gamma ray interactions inside the detector
Advantages and Innovations:
· A wide range of applications: medical diagnosis, dose monitoring during irradiation in hadron therapy, gamma ray telescopes, monitoring of decommissioning of nuclear power plants and homeland security
· A better sensitivity in commercial scanners (PET and SPECT) without degrading image.
· Improves image quality by a more efficient elimination of random and scattered events
