Satu 6401 is a linear detector array system for X-ray imaging, featuring a 64-channel probe board and a data acquisition board. Each board provides detection, at a 1.6 mm pixel pitch, and digital data acquisition at 16 bit. The probe board can be equipped with either 64 low-energy or high-energy detectors. 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.
