Development and validation of a 3D printed phantom for image quality assessment in fluoroscopy. [PDF]
J Appl Clin Med PhysAbstract Background Low‐contrast detectability is a key image‐quality parameter in fluoroscopy, directly influencing diagnostic accuracy and patient safety. Commercial phantoms such as the CDRAD provide reliable assessments but are costly and lack flexibility for routine use. Purpose To develop and validate a low‐cost 3D‐printed phantom for fluoroscopy

Refining imaging parameters for dual-energy cone-beam computed tomography in image-guided radiation therapy. [PDF]
J Appl Clin Med PhysAbstract Purpose To develop a dose estimation method for virtual monoenergetic images (VMIs) derived from sequential dual‐energy (DE) cone‐beam computed tomography (CBCT), enhancing image quality while reducing imaging dose. The goal is to generate VMIs with lower imaging dose than standard CBCT for future clinical applications.
