Fused perfusion and functional 3D rotational angiography rendering

Abstract

A Method and system for visualising information by combining 3DRA with diagnostic data like regular CT or MR, and colourised physiologic data like perfusion or functional data to obtain a plurality of volumes obtained from the same patient. These volumes may be a 3DRA volume, a regular greyscale CT or MR volume and a colourised physiologic parameter like a perfusion CT, a perfusion MR or a functional MR volume. Then, an anatomic structure like a vessel is segmented from the 3DRA volume, a slab out of the regular CT or MR data is rendered through the segmented vessel, and a slice out of the colourised volume of the perfusion or functional data is rendered on top of the slab.

Description

technical field [0001] The present invention relates to systems and methods for rendering images / views of anatomical structures such as vascular structures. In particular, the present invention relates to methods for registering images of 3D rotational angiography (3DRA) from scans of physiological data, such as from computed tomography (CT) or magnetic resonance (MR) scans, to obtain a combined image thereof or view systems and methods. Background technique [0002] Interventional X-ray angiography procedures are generally based on real-time two-dimensional (2D) minimally invasive image guidance through the vasculature or intravascular material of human vessels. The imaging modality of choice for interactive tracking of guidewires and catheters is the X-ray Vascular Machine. Typically, such interactive tracking of intravascular material (eg, guidewires and / or catheters) has been achieved by X-ray angiography instruments. The recently introduced three-dimensional rotation...

Problems solved by technology

This mode of presentation is not ideal because it is not possible for the clinician to interpret the 3D morphology of vessels from 2D cross-sections
