Abstract

Manual volume measurement of intracranial aneurysms from 3D rotational angiography varies on different threshold settings and, therefore, is operator-dependent. We developed and validated a method based on automatic gradient edge detection that is independent on threshold settings and provides an accurate and reproducible volume measurement. This method was compared with manual volume calculation in 13 aneurysm phantoms, and the results were significantly more accurate.
