An investigation of clinical treatment field delivery verification using cherenkov imaging: IMRT positioning shifts and field matching
Autor: Cheng-Shie Wuu, Paul J. Black, Yong Hum Na, Yi-Fang Wang, Christian Velten
Publikováno v: Medical Physics. 46:302-317
Purpose Cherenkov light emission has been shown to correlate with ionizing radiation dose delivery in solid tissue. An important clinical application of Cherenkov light is the real-time verification of radiation treatment delivery in vivo. To test th

Dosimetric verification and commissioning for a small animal image-guided irradiator
Autor: Yi-Fang Wang, Cheng-Shie Wuu, Yong Hum Na, Paul J. Black, Shih-Chi Lin
Publikováno v: Physics in medicine and biology. 63(14)
In recent years, small animal image-guided irradiators have been widely utilized in preclinical studies involving rodent models. However, the dosimetry commissioning of such equipment involving kilovoltage small-field dosimetry has not received as mu

Modelling and Monte Carlo organ dose calculations for workers walking on ground contaminated with Cs-137 and Co-60 gamma sources
Autor: Peter F. Caracappa, J Zhang, X. George Xu, Yong Hum Na, Bin Han
Publikováno v: Radiation Protection Dosimetry. 141:299-304
A pair of walking phantoms was developed from deformable mesh phantoms to represent individuals walking on contaminated ground. The Monte Carlo N-particle extended version code was used to calculate organ doses from ground contamination scenarios inv

Deformable adult human phantoms for radiation protection dosimetry: anthropometric data representing size distributions of adult worker populations and software algorithms
Autor: Yong Hum Na, Peter F. Caracappa, J Zhang, X. George Xu, Binquan Zhang
Publikováno v: Physics in Medicine and Biology. 55:3789-3811
Computational phantoms representing workers and patients are essential in estimating organ doses from various occupational radiation exposures and medical procedures. Nearly all existing phantoms, however, were purposely designed to match internal an
