Title:
RADIOGRAPHY DEVICE, RADIOGRAPHY SYSTEM, RADIOGRAPHY METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/066570
Kind Code:
A1
Abstract:
Provided is a radiography device with which, by correcting an energy feature value which is computed from a variance value and a mean value of pixel values of a radiographic image, it is possible to acquire a high-precision mean energy image. This radiography device comprises: a computation means which computes an energy feature value of radiation from a variance value and a mean value of pixel values of a radiographic image; and a correction means which, by correcting variations of the energy feature value on the basis of the mean value, computes the mean energy of the radiation.
