IMAGE DISPLAY APPARATUS AND X-RAY CT APPARATUS

摘要

An image display apparatus and an X-ray CT apparatus is provided to display a three-dimensional image without degradation of spatial resolution by improving an S/N ratio and reducing an artifact. A two-dimensional X-ray region detector is opposite to an X-ray generator in order to detect an X-ray from the X-ray generator. An X-ray data collection unit collects X-ray projection data transmitted through a target at a position between the X-ray generator and the two-dimensional X-ray region detector. An image reproduction unit reproduces the projection data collected from the X-ray data collection unit. An image display unit displays the reproduced tomographic image. An imaging condition set unit sets imaging conditions for collection and display. The image display unit includes an image filter processing device for displaying the two-dimensional image extracted from a three-dimensional image. The image filter is changed along a cross-sectional direction of the two-dimensional image to be displayed.
