DOI: 10.1002/acm2.13517
Abstract: Abstract We investigated the dose deviation related to geometric distortion and dose gradient on magnetic resonance‐only treatment planning for intensity‐modulated radiation therapy and proton therapy. The residual geometric distortion of two different magnetic resonance imaging… read more here.

DOI: 10.1109/tgrs.2021.3078815
Abstract: Noticeable striping artifacts in collected satellite imagery, caused by the inconsistency of pushbroom sensor detector responses, degrade the image quality. Relative radiometric calibration aims to calibrate inconsistencies in terms of detector responses, thereby eliminating detector-level… read more here.

DOI: 10.1109/tie.2021.3060673
Abstract: Rectification is a standard process in every system that requires multiviews. Existing algorithms largely work on similar field of view (FoV) cases where the two views are mostly identical. Dissimilarities between different FoVs can generate… read more here.

DOI: 10.1117/1.jei.28.3.033023
Abstract: Abstract. As streak tube imaging is a concentric spherical electrostatic focusing system, geometric distortion is caused by the relative change in radial magnification. This reduces the spatial resolution of imaging. The physical principle of changing… read more here.
