Image display apparatus and X-ray CT apparatus

摘要

The present invention aims to realize an improvement in image quality of a two-dimensional display extracted from a three-dimensional display image such as continuous tomographic images which tomographic images at a conventional scan or the like of an X-ray CT apparatus having a two-dimensional X-ray area detector of a matrix structure typified by a multi-row X-ray detector or a flat panel X-ray detector are arranged in a z direction corresponding to an imaging table travel direction. For the purpose, an image display apparatus of the present invention comprises image filter processing device for preforming a image filter processing on the three-dimensional image, wherein said image filter process varies depending on a cross sectional direction of said two-dimensional image to be displayed.
