Measurement of CT radiation beam width with a pencil ionization chamber and radiopaque mask
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose This study compares fan beam CT scanner radiation beam widths measured with a pencil ionization chamber‐radiopaque mask technique with commonly used film and computed radiography (CR) measurements. Methods For a given fan beam CT scanner x‐ray beam, the ionization chamber‐mask technique determines the radiation beam width by exposing a

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Single‐isocenter multitarget (SIMT) radiosurgery has become increasingly popular as advancement in planning and delivery systems have made this approach clinically viable. With targets varying in size and distance from isocenter, SIMT plans are highly complex with dynamic multileaf collimator (MLC) motion.

Calmodulin and Calcium-release Channels
Biological Research, 2004 Calmodulin (CaM) is a ubiquitous cytosolic protein that plays a critical role in regulating cellular functions by altering the activity of a large number of ion channels.

Hybrid PDE-Deep Neural Network Model for Calcium Dynamics in Neurons [PDF]
arXivTraditionally, calcium dynamics in neurons are modeled using partial differential equations (PDEs) and ordinary differential equations (ODEs). The PDE component focuses on reaction-diffusion processes, while the ODE component addresses transmission via ion channels on the cell's or organelle's membrane.

Evaluation of the effect of metal stents on dose perturbation in the carbon beam irradiation field
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Propose Carbon ion therapy is indicated for cases in which stents have been inserted, such as bile ducts, but the effect of metal stents on carbon ion therapy is unclear. In this study, the dose perturbation of carbon ion therapy caused by metallic bile duct stents was evaluated by dosimetry. Materials and methods Five different types of metal
