Retrospective cardiovascular dosimetry studies after radiation therapy are based on a representative patient or simple mathematic phantoms. Computational phantoms can be built to fit the patient anatomy, and a detailed heart model with coronary arteries can be included in the phantom. When the available anatomic information is scarce, it is suggested that computational phantoms improve the accuracy of retrospective dose calculation. The detailed heart model eliminates the problem of identifying coronaries on the patient CT.
