Performance Criteria

Energy Resolution

Criteria

With the presence of scatter, medium and high background activity compton photons produce an additional blurring of the spatial information. An energy discrimination that separates compton- and photopeak-signal is therefore important.

Crystal Probe's Performance

The Crystal Probe’s energy resolution is one of the best on the market. Good energy resolution is one of the most important requirements to consider. When the body is injected with radioactivity, Cobalt 57 for example, in order to identify the sentinel lymph node, the probe should detect Cobalt 57 photopeak signal only and not scatter radiation.
