Title:
X-RAY IMAGING METHOD AND X-RAY IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2023059177
Kind Code:
A
Abstract:
To provide an X-ray imaging method capable of reducing noise sufficiently and acquiring a re-configured image in which image quality is improved, in a photon counting type X-ray imaging for detecting an X-ray photon.SOLUTION: There is provided an X-ray imaging method comprising: a step for radiating an X-ray to a subject 200 and acquiring a detection result of an X-ray photon generated by an X-ray passed through the subject 200; a step for, on the basis of the detection result of the X-ray photon, generating a plurality of re-configured images 11 in energy ranges which are different from each other; and a step for using a deep layer convolution neural network 7 to perform deep layer image processing in which the processing is stopped before convergence of the deep layer convolution neural network 7 with the plurality of re-configured images 11 as pieces of inputs of the deep layer convolution neural network 7, thereby generating a plurality of noise reduced re-configured images 12.SELECTED DRAWING: Figure 3
