Abstract
Tomosynthesis presents a simple procedure for 3D angiography, because the recording step requires only one injection of contrast medium. Digital flashing tomosynthesis is based on a new nonlinear reconstruction producing less artifacts than conventional backprojection techniques. In addition to reconstructed slices synthetic projections can be calculated, which can be used in combination with the original projections for stereo views. The object structures can be analysed by a stereo cursor controlled by a 3D joystick. This may be an important adjunct to diagnostic and interventional angiographic procedures.
