    摘要: An extracting step (step S1) extracts uninfluenced pixels with a relatively high degree of certainty, while avoiding influences of random quantum noise as much as possible. An approximate fluoroscopic image is obtained based on such uninfluenced pixels (step S2). Thus, accuracy of the approximate fluoroscopic image can be improved over that of the prior art. Therefore, a grid foil shadow image (step S3) and a foil shadow standard image (step S4) calculated successively based on the approximate fluoroscopic image have improved accuracy over the prior art. As a result, while inhibiting influences of random quantum noise, a foil shadow removed image can be obtained which is free from artifacts due to distortion of a synchronous grid.

    摘要: A radiographic apparatus includes a radiation source for emitting radiation, a radiation detection device having radiation detecting elements arranged longitudinally and transversely for detecting the radiation, a radiation grid, and an object image correcting device. The object image correcting device generates a corrected image by deriving components of direct radiation in pixel values of an object image from a dark equation specifying that an average of radiation intensity in a dark pixel group formed of a dark pixel showing a shadow of one of absorbing foil strips and adjacent pixels transversely adjoining the dark pixel of each image is a sum of the components of direct radiation and components of indirect radiation, and light equations specifying that an average of radiation intensity in light pixels free of the shadows of the absorbing foil strips is a sum of the components of direct radiation and the components of indirect radiation.

    摘要: A tomographic apparatus of this invention includes a dividing unit for dividing a sectional image into a pixel group including artifacts and a pixel group not including artifacts by carrying out an independent component analysis (ICA) of the artifacts, and a pixel group processing unit for applying a smoothing filter as a predetermined process relating to correction only with respect to the above pixel group including the artifacts, whereby a correction process is carried out to remove the artifacts. Thus, the artifacts can be removed stably.
