Obese patient imaging: Potential dose reduction with photon‐counting CT

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Photon‐counting CT (PCCT) offers key advantages over energy integrating detector CT (EID‐CT), especially in low‐dose scans and imaging larger patients. As obesity rates rise, minimizing image noise is critical for diagnostic accuracy.

Assessment of 6MV flattening filter free (FFF) beam commissioning parameters for Versa HD and TrueBeam: A comparison study

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Flattening filter‐free (FFF) beams are increasingly deployed for stereotactic body radiotherapy (SBRT) and stereotactic radiosurgery (SRS). The Elekta Versa HD (VHD) and Varian TrueBeam (TB) are the two most widely used FFF‐capable platforms; however, no prior study has compared their 6 MV FFF commissioning parameters under fully ...

K‐Edge imaging using a clinical dual‐source photon‐counting CT system

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Photon‐counting CT (PCCT) enables K‐edge imaging, an advanced multi‐material decomposition technique that requires multiple energy bins to perform decomposition unconstrained by physical assumptions. The clinical implementation of K‐edge imaging applications like dual‐contrast imaging could lead to reductions in radiation dose and ...

Monte carlo assessment of advanced shielding materials for space‐efficient radiotherapy vault design

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Conventional radiotherapy vault shielding typically employs 2 to 3 meters of ordinary concrete, consistent with NCRP Report 151 reference data. While NCRP 151 specifies dose‐based design goals rather than mandating particular materials, the practical default of concrete results in vault footprints of 150 to 200 m2 per linac, which ...

Quantitative evaluation of respiratory motion‐induced blurring in expiratory‐phase CBCT for pancreatic SBRT

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is widely used in image‐guided radiotherapy because it reflects the patient's anatomy immediately before treatment. However, CBCT images of the abdominal organs, including the pancreas, are often degraded by respiratory motion.
