Title: Key Jo Hong: Innovator in PET Detector Technology

Introduction

Key Jo Hong is a distinguished inventor based in Seoul, South Korea, known for his contributions to the field of medical imaging. With a focus on enhancing positron emission tomography (PET) technologies, he holds two patents that showcase his innovative approach to improving diagnostic imaging.

Latest Patents

His latest patents include a "Pet detector module using GAPD composed of large area micro-cells," which combines cutting-edge technology with medical applications. This module utilizes Geiger-mode avalanche photodiode (GAPD) as a photosensor. The patent details a PET detector unit that employs scintillation crystals to detect gamma rays emitted from a living body, allowing for the conversion of these rays into scintillation light. The integration of two GAPD photosensors enhances the detection process by converting this light into electrical signals. Additionally, a depth of interaction (DOI) decoding unit analyzes these signals, improving energy resolution and providing valuable DOI information while maintaining linearity.

Another significant contribution is the "PET-MRI combination apparatus," designed to extend both transaxial and axial fields of view (FOV). This innovative apparatus allows for the transmission of output signals from the photo sensor outside the confines of an MRI bore using a cable. The apparatus includes a meticulously designed MRI bore for capturing MR images, with a PET detector strategically installed to maximize imaging capabilities. Furthermore, the PET circuit unit is located outside the MRI bore, ensuring that it remains unaffected by magnetic fields, which is crucial for optimal functioning.
