Computer measurement and representation of the heart in two and three dimensionsMethods for accurate measurement and meaningful display of cardiac dimensions as obtained from fluoroscopy were surveyed. Recorded images were scaled back to actual dimensions and cardiac motion was displayed to assess functional changes. This was accomplished by use of a low-cost but flexible ensemble of computer and video equipment which assisted in (1) digitizing image outlines or points, (2) filing digitized images for later recall in any sequence, (3) correcting recorded images for distortion, (4) modeling heart geometry, (5) analyzing dimensional changes, and (6) displaying both heart geometry and results of analysis in a useful form.
