Bolus-chasing CT angiography is an important new imaging mode for imaging cardiovascular structures and peripheral vessels. The adaptive bolus-chasing method implies a variable pitch spiral cone-beam CT scan. In this paper, we extend 2D-weighted, 3D-weighted and tilted plane FDK algorithms for...
This paper describes a method for reconstructing 3D frontier points, contour generators and surfaces of anatomical objects or smooth surfaces from a small number, e.g. 10, of conventional 2D X-ray images. The X-ray images are taken at different viewing directions with full prior knowledge of the...
Diffuse optical tomography (DOT) is an emerging imaging modality for non-invasive brain functional mapping. The hemodynamic and metabolic images derived from optical properties are unique and complementary to those of magnetic resonance imaging (MRI) and positron emission tomography (PET). In...
Since Katsevich's work on cone-beam CT in 2002, a series of new reconstruction formulae for cone-beam and fan-beam reconstruction have been published. To understand these new results in a unified way, two schemes were proposed in the literature: one is based on the Radon formula, while the other...
