You are planning to build a second-generation scanner. The following parameters are given: d: source-to-center distance r: radius of measurement circle delta: fan angle What is the minimum translation that you have to allow for this scanner?

Solution

Second generator scanner has 30 detectors which allow 6 times linear movements as opposed to 180 times in first generation

Thus each detector moves 6 units in translation.

Minimum translation = radius of the measurement circle ie

Tan (alpha /2) = r/d
