The core part to solve the digitization problem of traditional X-ray photography is

Traditional X-ray photography directly images in two-dimensional space. From the data acquisition of digital imaging, only single point or one-dimensional signal is taken, and the obtained single point or one-dimensional signal is reconstructed into two-dimensional image by computer. It can be seen that to solve the digitization problem of conventional X-ray photography, the core part is the digital acquisition of two-dimensional signals.
