Computed Triple Orthogonal Projections for Optimal Radiological Imaging with Biplane Isocentric Multidirectional X-ray Systems

One of the major objectives in angiocardiography is the visualization of anatomical details with projections perpendicular to the long axis of the anatomical structure. In addition, ‘one of the most basic rules in radiology . . . is the need for at least two views of the object with the projections being perpendicular to each other’ [1]. Thus, most useful informations can be derived from a radiological study if the concept of ‘triple orthogonality’ is applied: two projections perpendicular to the long axis of the anatomical object and perpendicular to each other.
