Radiation therapy treatments are typically planned based on a single image set, assuming
that the patient's anatomy and its position relative to the delivery system remains constant …

The main components of scatter correction procedures are scatter estimation and a scatter
compensation algorithm. This paper completes a previous paper where a general …

Purpose: Due to the increased axial coverage of multislice computed tomography (CT) and
the introduction of flat detectors, the size of x‐ray illumination fields has grown dramatically …

Computed tomography has greatly improved over the last decade, especially through x-ray
dose exposure reduction while maintaining image quality. Herein, a new concept is …

Purpose Scattered radiation is a major cause of image quality degradation in flat panel
detector‐based cone beam CT (CBCT). While recently introduced 2D antiscatter grids reject …

In cone beam breast computed tomography (CT), scattered radiation leads to nonuniform
biasing of CT numbers known as a cupping artifact. Besides being visual distractions …

Purpose: One well‐recognized challenge of cone‐beam computed tomography (CBCT) is
the presence of scatter contamination within the projection images. Scatter degrades the …

A patient-specific scatter correction algorithm is proposed to mitigate scatter artefacts in cone-
beam CT (CBCT). The approach belongs to the category of convolution-based methods in …

Aim High fraction of scattered radiation in cone‐beam CT (CBCT) imaging degrades CT
number accuracy and visualization of low contrast objects. To suppress scatter in CBCT …

Purpose We have been investigating two‐dimensional (2D) antiscatter grids (2D ASGs) to
reduce scatter fluence and improve image quality in cone beam computed tomography …
