Abstract :
By taking advantage of the good energy resolution of CdTe detectors, gamma rays scattered by lead collimators can be rejected leading to excellent spacial resolution for medical probes. Since CdTe has over 100 times the photoelectric stopping power of Si at 140 keV (99mTc), the probe provides enough sensitivity that dental abscesses on the individual root tips of test animal teeth can be detected weeks before they are evident by radiographs.
