The CZT modules, which consist of CZT plus the electronics, are populated on a column with Tungsten collimators in front which channel the photons to the detector array. Using Tungsten collimators rather than lead eliminates potential lead X-ray which can degrade image quality.
The semiconductor, CZT, combined with our unique implementation of hardware and software, offers superior performance advantages over Sodium Iodide. The most important is the dramatic improvements in sensitivity and energy resolution. This gives the D-SPECT the ability to acquire low dose and simultaneous multiple energy studies.
