  • Device for and method of subtraction imaging with reduction of motion artefacts
    Patent number: 4870692
    Abstract: Images formed by digital subtraction angiography are improved by subtracting a locally deformed image from another image. A subtraction image is obtained which is substantially free from motion artefacts and which contains only the information of a moving contrast medium. To achieve this, a shift vector is determined for various pixels and a reliability criterion is calculated for each direction component of said shift vector.
