Positron Emission Tomography

Introduction

Medical imaging uses various techniques which all have in common that from measured data an immage of an internal organ has to be constructed. For example, for an X-ray scan the absorption of X-rays by tissues in the human body is recorded as data. The recorded X-ray absorption data needs to be converted into an image. This conversion process is called image reconstruction or image processing.

This experiment focuses on a limited number of aspects of the techniques applied for image reconstruction. This is done through a simulation of a Positron Emission Tomography (PET)-camera, and a remote lab of a PET-experiment.

First, the principle of a PET-camera is explained through a short video (double-click on video):

The collection of data in the experiment is a bit time consuming.

While the experiment is running the image reconstruction techniques can be studied through simulations.
