Satu 6404A is a linear detector array system for X-ray imaging, featuring a probe board and a data acquisition board. Each probe board is equipped with 64 low-energy and 64 high-energy detectors. Each board provides detection, at a 1.575mm pixel pitch. Multiple boards can be connected together. This creates a detector array of a certain length in order to meet the imaging requirements of various applications requiring a different number of imaging channels.
