The edge visualization metric: Quantifying the improvement of lung SBRT target definition with 4D CBCT

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Four‐dimensional cone‐beam CT (4D CBCT) incorporates oversampling of 3D data to reconstruct multi‐phase CBCT data sets representing distinct phases of the breathing cycle based on a diaphragmatic correlate of respiratory motion. Motion artifacts and blurring can be reduced relative to three‐dimensional cone‐beam (3D CBCT), allowing ...

Long‐term stability analysis of beam shape in a robotic radiosurgery system

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study aimed to investigate the long‐term stability of CyberKnife beam profile parameters and assess their compliance with existing quality assurance (QA) guidelines. We evaluated beam profiles in both standard and diagonal planes over 3.5 years post‐installation to detect potential issues and ensure consistent beam quality.

Does endurance fatigue increase the risk of injury when performing drop jumps? [PDF]

open access: yes, 2009
Although from an athletic performance perspective it may be beneficial to undertake drop jump training when fatigued (principle of "specificity" of training), such endur-ance fatigue may expose the body to a greater risk of injury if it causes an ...
