Title: Verner Toefting and Gamma Camera Correction Technology.

Introduction

Verner Toefting is an inventor associated with Nivaa, Denmark, and General Electric Company. His patent work addresses image correction in gamma camera systems, which detect and display radiation events.

Latest Patents

The available information identifies one patent for Toefting: “Scintillation Camera System with Improved Means for Correcting.” The invention helps correct mismatches between the actual positions of scintillations and the coordinates calculated by a gamma camera system.

During calibration, a first memory matrix records counts from incremental areas of the radiation field under a uniform source. Once a preset count threshold is reached in at least one location, accumulation stops, leaving other locations with fewer counts. During operation, a second memory matrix stores incoming counts, which are compared with the calibration data. The system then adds counts to compensate for differences and improve image uniformity. Toefting is credited with 1 patent.

Career Highlights

Toefting’s documented contribution focuses on improving the accuracy and uniformity of gamma camera images. The patent describes a method that combines coordinate calculation, pulse-height analysis, memory-based calibration, and count correction.
