A Combined Time-Walk and Timing-Shift Correction Method for Dual-Ended Readout TOF-DOI PET Detector

Abstract

Researchers at the University of California, Davis have developed a technology that significantly improves the timing and spatial resolution of PET scans using dual-ended readout detectors.

Full Description

The technology pertains to advanced positron emission tomography (PET) systems equipped with dual-ended readout detectors, designed to enhance both timing and spatial resolution. By employing corrected timing information generated through methods such as time-walk correction and timing-shift correction, these systems can more accurately identify and log the times at which photons are received. This leads to improved image quality by accurately estimating the location of positron-electron annihilations, crucial for detailed medical imaging.

Applications

• Medical diagnostic imaging for detecting, diagnosing, and monitoring diseases. 
• Research applications in biology and pharmacology for studying physiological processes. 
• Advanced imaging techniques in oncology for tumor detection and treatment monitoring.

Features/Benefits

• Enhanced timing resolution through corrected timing information. 
• Improved spatial resolution by accurately estimating annihilation events. 
• Ability to use various scintillation crystal elements for versatile imaging needs. 
• Advanced processing for depth-of-interaction layer analysis, improving image detail.
