X-ray diagnostics apparatus with correction means

摘要

An X-ray diagnostics apparatus in which sensitivity of an overlapped image is uniform everywhere. The X-ray diagnostics apparatus includes: a first image sensing device which senses analog image; a first A-D converter which converts the analog image obtained by the first image sensing device to a digital image; a first memory which stores digital-converted image data obtained by the first A-D converter; a second image sensing device which senses an analog image; a second A-D converter which converts the analog image obtained by the second image sensing device to a digital image; a second memory which stores digital-converted image data obtained by the second A-D converter; a divider unit which generates coefficient in which the image data stored in the first memory is divided by the image data stored in the second memory; line memory which stores the generated coefficient; and composite image memory which overlapps image data obtained by the first memory and the second memory in a manner that the coefficient is multiplied to the image data in the second memory for each line.
