Embodiment Construction

[0025] In the following description, many specific details are explained, such as examples of specific components, devices, methods, etc., to provide a comprehensive understanding of the implementation of this framework. However, it will be obvious to those skilled in the art that it is not necessary to adopt these specific details to practice the implementation of this framework. In other instances, well-known materials or methods are not described in detail to avoid unnecessarily obscuring the implementation of this framework. Although the present framework is susceptible to various modifications and alternative forms, its specific embodiments are shown in the drawings by way of example and will be described in detail here. However, it should be understood that it is not intended to limit the present invention to the specific forms disclosed, but on the contrary, it is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of th...

Abstract

Systems and methods are provided for data reconstruction. In accordance with one aspect, data interpolation is performed on a time-varying three-dimensional (3D) image dataset of one or more vessel-like structures to generate at least one interpolated voxel value. The interpolated voxel value is used to correct at least one value of a vessel voxel representing the one or more vessel-like structures in the time-varying 3D dataset.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 838,928, filed June 25, 2013, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates generally to image data processing, and more particularly to reconstruction of time-varying data. Background technique [0004] Angiography is a common method for representing blood vessels based on diagnostic imaging methods such as X-ray or Magnetic Resonance Tomography (MRT). To improve the representation of vessels under examination, digital subtraction angiography (DSA) has been developed. DSA is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in bony or dense soft tissue environments. The image is generated by subtracting a 'pre-contrast image' or mask from subsequent images acquired after the contrast agent has been introduced into the structur...
