Method for Imaging Plaque Using Dual Energy CT |
摘要 |
Two x-ray CT images are acquired of arterial plaque using x-rays at two different energy levels. The reconstructed images are normalized by adjusting pixel brightness until pixels depicting a region containing calcium have substantially the same brightness. The normalized images are subtracted to produce an image that depicts iron in the arterial plaque.
