Imaging system QA of a medical accelerator, Novalis Tx, for IGRT per TG 142: our 1 year experience.
(Journal of applied clinical medical physics, 2012-07-05)
American Association of Physicists in Medicine (AAPM) task group (TG) 142 has recently published a report to update recommendations of the AAPM TG 40 report and add new recommendations concerning medical accelerators in ...
Computed tomography dose index and dose length product for cone-beam CT: Monte Carlo simulations.
(Journal of applied clinical medical physics, 2011-01-19)
Dosimetry in kilovoltage cone beam computed tomography (CBCT) is a challenge due to the limitation of physical measurements. To address this, we used a Monte Carlo (MC) method to estimate the CT dose index (CTDI) and the ...
Evaluation of an electron Monte Carlo dose calculation algorithm for electron beam.
(Journal of applied clinical medical physics, 2008-06-23)
The electron Monte Carlo (eMC) dose calculation algorithm of the Eclipse treatment planning system is based heavily upon Monte Carlo simulation of the linac head and modeling of the linac beam characteristics with minimal ...
Investigation of sliced body volume (SBV) as respiratory surrogate.
(Journal of applied clinical medical physics, 2013-01-07)
The purpose of this study was to evaluate the sliced body volume (SBV) as a respiratory surrogate by comparing with the real-time position management (RPM) in phantom and patient cases. Using the SBV surrogate, breathing ...
Text Recycling in Scientific Writing.
(Science and engineering ethics, 2019-06)
Text recycling, often called "self-plagiarism", is the practice of reusing textual material from one's prior documents in a new work. The practice presents a complex set of ethical and practical challenges to the scientific ...
Germinal center entry not selection of B cells is controlled by peptide-MHCII complex density.
(Nature communications, 2018-03-02)
B cells expressing high affinity antigen receptors are advantaged in germinal centers (GC), perhaps by increased acquisition of antigen for presentation to follicular helper T cells and improved T-cell help. In this model ...

(Precision Clinical Medicine, 2019-10-01)
<jats:title>Abstract</jats:title> <jats:p>Cancer cells undergo metabolic reprogramming to support cell proliferation, growth, and dissemination. Alterations in lipid metabolism, and specifically the uptake ...
Hip extensor mechanics and the evolution of walking and climbing capabilities in humans, apes, and fossil hominins.
(Proceedings of the National Academy of Sciences of the United States of America, 2018-04-02)
The evolutionary emergence of humans' remarkably economical walking gait remains a focus of research and debate, but experimentally validated approaches linking locomotor capability to postcranial anatomy are limited. In ...
