How does a CZT detector work?
How does a CZT detector work?
The CZT detector works as a semiconductor with direct conversion of gamma radiation to electric signal. This mechanism results in better spatial resolution and sensitivity, what means lower administered dose of radiopharmaceutics and/or shorter acquisition time.
How do you measure the resolution of an energy detector?
%Energy resolution = FWHM x 100 /photo peak Energy resolution is expressed as a percent of the FWHM of a specific energy. Most cameras have an energy resolution in the range of 11% to 13% FWHM at 140 KeV.
What is energy resolution of scintillation detector?
Energy resolution of scintillation detectors used in gamma-ray spectroscopy is often dictated by the number of cathode electrons in the associated photo-multiplier tube (PMT). This is particularly true for lower light yield, high refractive index scintillator materials.
What are CZT detectors?
CZT is a unique semiconductor compared with silicon and germanium detectors – cadmium zinc telluride CZT operates at room temperature and can process >2million photons / second /mm2. Additionally, CZT’s spectroscopic resolution clearly outperforms any commercially available scintillator.

What is meant by the energy resolution of the spectrometer?
energy resolution,spectrum resolution The energy resolution in elemental analysis using X-ray spectroscopy means the minimum energy (eV) of a spectral peak that can be resolved. Two peaks of a spectrum that are separated by about the full width at half maximum (FWHM) are distinguishable.
What is NaI detector?
A NaI(Tl) scintillation counter is a radiation detector which uses the effect known as scintillation. Scintillation, which occurs in the NaI(Tl) crystal, is a flash of light produced in a transparent material by the passage of a particle (an electron, an alpha particle, an ion, or a high-energy photon).
