Three-Dimensional Coronary Angiography with Digital Flashing Tomosynthesis
Tomosynthesis presents a simple procedure for angiography because the recording step requires only one injection of contrast medium. Digital flashing tomosynthesis (DFTS) is based on a new nonlinear reconstruction producing fewer artifacts than conventional back projection in the case of subtraction angiography. Therefore, the number of X-ray tubes can be reduced to four, and synthetic projections can be calculated from reconstructed slices. These projections can be used for 3-D presentations.
