In this study, we propose an image-domain non-uniformity correction algorithm on CBCT images. The algorithm is based on the assumption that the non-uniformity ...
Cone-beam CT (CBCT) is been increasingly used in radiation therapy for patient setup, dose verification and adaptive planning. However, the non-uniformity ...
The technique, which is fast, automatic, and knowledge-based, has two major steps. First, it searches the whole image volume to find all markerlike objects and ...
This study proposes an image-domain non-uniformity correction algorithm on CBCT images based on the assumption that the non- uniformity of voxel values of ...
Nov 8, 2015 · In this work, we develop a novel algorithm for shading correction directly on CBCT images. Distinct from other image-domain correction methods, ...
Nov 8, 2015 · As our method suppresses only low‐frequency shading artifacts, patient anatomy and contrast were retained in the corrected images for both cases ...
