3-D reconstruction of coronary arterial trees from uncalibrated monoplane angiographic images

This paper presents a novel method for the 3-D reconstruction of coronary arterial trees from two uncalibrated monoplane angiographic images. This method does not require independent calibration of the phantom. The lower-order distortion, transformations of the C-arm and the movement of the table can be effectively estimated. This method is very flexible because it can not only be applied to images with the same focal lengths, but also can be used to images with different focal lengths. Experimental results show that the proposed method is very robust and effective for the reconstruction of coronary arterial trees, and is able to achieve less than 0.26 mm of back-projection RMS errors, which represents a great improvement on the accuracy of the 3-D reconstruction of coronary arteries from uncalibrated images.
