<P>PROBLEM TO BE SOLVED: To provide an X-ray diagnostic apparatus and an X-ray diagnostic program attaining simultaneous observation of a portion extracted by subtraction processing, and a high contrast object and a low contrast object in a background. <P>SOLUTION: A subtraction image creating section 35 creates a subtraction image by carrying out subtraction processing from a mask image acquired based on the output of an X-ray detector 7 and on a live image acquired based on the output of the X-ray detector 7. In parallel with the subtraction processing, a dynamic range compressed image creating section 37 creates a dynamic range compressed image using one of the mask image and live image and carrying out dynamic range compression only to low frequency components out of the low frequency components and high frequency components included in the image. A composite image creating section 43 creates a composite image by superimposing the subtraction image and the dynamic range compressed image. <P>COPYRIGHT: (C)2012,JPO&INPIT |
