The effect of multi‐leaf collimator leaf width on VMAT treatment plan quality
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background The advent of volumetric modulated arc therapy (VMAT) in radiotherapy has made it one of the most commonly used techniques in clinical practice. VMAT is the delivery of intensity modulated radiation therapy (IMRT) while the gantry is in motion, and existing literature has shown it has decreased treatment delivery times and the ...

Increase in surgical fixation of pediatric midshaft clavicle fractures since 2008
BMC Musculoskeletal Disorders, 2022 Background Clavicle fractures in children have traditionally been treated non-operatively. In adults, a great increase in operative treatment has been reported.

Monte Carlo modeling of radiation dose from radiation therapy with superficial x‐rays
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Introduction Superficial x‐rays (50–100 kVp) are used for treating non‐melanoma skin cancer and intraoperative radiation therapy (IORT). At these energies, the photoelectric effect significantly increases absorbed dose to bone compared to soft tissue.

Axisymmetric displacement flows in fluid-driven fractures [PDF]
Journal of Fluid Mechanics. 2022;953:A36Displacement flows are common in hydraulic fracturing, as fracking fluids of different composition are injected sequentially in the fracture. The injection of an immiscible fluid at the center of a liquid-filled fracture results in the growth of the fracture and the outward displacement of the interface between the two liquids. We study the dynamics of

A System for 3D Reconstruction Of Comminuted Tibial Plafond Bone Fractures [PDF]
arXiv, 2021 High energy impacts at joint locations often generate highly fragmented, or comminuted, bone fractures. Current approaches for treatment require physicians to decide how to classify the fracture within a hierarchy fracture severity categories. Each category then provides a best-practice treatment scenario to obtain the best possible prognosis for the ...

Streaming potential modeling in fractured rock: Insights into the identification of hydraulically active fractures [PDF]
Geophysical Research Letters 43 (2016), 2016 Numerous field experiments suggest that the self-potential (SP) geophysical method may allow for the detection of hydraulically active fractures and provide information about fracture properties. However, a lack of suitable numerical tools for modeling streaming potentials in fractured media prevents quantitative interpretation and limits our ...

Investigations into the opening of fractures during hydraulic testing using a hybrid-dimensional flow formulation [PDF]
arXiv, 2021 We applied a hybrid-dimensional flow model to pressure transients recorded during pumping experiments conducted at the Reiche Zeche underground research laboratory to study the normal opening behavior of fractures due to fluid injection. Two distinct types of pressure responses to flow-rate steps were identified and numerically modelled using a radial ...
