A high performance 1024 × 1024 digital x-ray panel with integrated readout electronics for nondestructive testing and medical imaging applications

Prime View International (PVI) has developed a 4 times 4- inch digital X-ray panel with 1024 times 1024 resolution. The panel is built with a-Si PIN diodes and thin-film transistors (TFTs) for the detector array with readout integrated circuits (ROICs) from FLIR Systems Inc. The panel's integrated electronics are capable of on-chip low-pass filtering, correlated double sampling, and programmable 9 to 14-bit analog-to-digital conversion. The detector panel is read out using eight FLIR System's 128-channel 80-micrometer-pitch readout integrated circuits (ISC9717) abutted along the columns of the 1024 x 1024 detector array. The pixel size of detector array is 100 micrometers and fabricated by a standard TFT process plus an exclusive PIN process. This high performance, digitally integrated X-ray imaging solution is especially suitable to meet the rising demands of industrial nondestructive testing and medical imaging applications.
