New Gamma camera design

From World's Largest Market-Place for Inventions in Geneva, UPM researchers show a new design for a gamma camera which reduces its weight from 115 kg to just 45 kg.

This week, University Putra Malaysia's team unveiled their latest inventions and products at the 34th International Exhibition of Inventions, New Techniques and Products in Geneva (April 2-6, 2008), also known as the World's Largest Market-Place for Inventions.

This research is on a new design for a gamma camera which reduces its weight from 115 kg to just 45 kg

TITLE: Wire Mesh Collimator for Gamma Camera

In this project, we propose a design of a wire-mesh collimator which has only 51.2% the weight of the full multihole collimator and produces raw images of comparable quality with those produced by the full multihole collimator. On top of that, using Wiener filtering post processing improves the quality of the produces images further. A wire-mesh collimator, with only 39.5% the weight of the full multihole collimator, in conjunction with Wiener filtering, produces images of comparable quality with the unfiltered images produced by the full collimator. Thus, we show that a careful hardware design we are able to replace the 115kg collimator with a 45kg one.
