Work in progress. Flashing tomosynthesis: a tomographic technique for quantitative coronary angiography.
Flashing tomosynthesis, a procedure that consists of a recording step and a reconstruction step, facilitates the tomographic imaging of coronary arteries. In a comparative study 10 postmortem coronary arteriograms were examined with 35-mm cine technique and with flashing tomosynthesis. The degrees of stenosis found with both of these techniques were compared with morphometrically obtained values. A higher correlation coefficient existed for the degrees of stenosis obtained with tomosynthesis and morphometry (r = 0.92, p less than 0.001, SEE = 9%) than for those obtained with cine technique and morphometry (r = 0.82, p less than 0.001, SEE = 16%). The technique has also been successfully carried out in 5 patients with coronary artery disease.
