BACKGROUND Intensity modulated radiation therapy (IMRT) dosimetry verification is routinely conducted via integrated or individual field dosimetry using film or a matrix of detectors. Techniques and software systems are commercially available which use individual field dosimetry measurements as input into algorithms that estimate 3D patient dose(More)
Mention of a product does not constitute a warranty by the U.S. Department of Agriculture and does not imply its approval to the exclusion of other products that may also be suitable. Abstract: An investigation of the relationships among fiber linear density, tenacity, and structure is important to help cotton breeders modify varieties for enhanced fiber(More)
The Uster ® High Volume Instrument (HVI ®) is used in the U.S. to classify cotton, including cotton color. The cotton color parameters measured on the HVI are Rd (diffuse reflectance) and +b (yellow-ness). Comments from industry have indicated that some cotton bales appeared to have changed significantly in +b (yellowness) from their initial HVI color(More)
Growing interest in proton and heavy ion therapy has reinvigorated research into the fundamental biological mechanisms underlying the therapeutic efficacy of charged-particle radiation. To improve our understanding of the greater biological effectiveness of high-LET radiations, we have investigated DNA double-strand breaks (DSBs) following exposure of(More)
Kilovoltage cone-beam CT (kV CBCT) can be acquired during the delivery of volumetric modulated arc therapy (VMAT), in order to obtain an image of the patient during treatment. However, the quality of such CBCTs is degraded by megavoltage (MV) scatter from the treatment beam onto the imaging panel. The objective of this paper is to introduce a novel MV(More)
Infrared imaging is gaining attention as a technique used in the examination of cotton fibers. This type of imaging combines spectral analysis with spatial resolution to create visual images that examine sample composition and distribution. Herein, we report on the use of an infrared instrument equipped with a reflection accessory and an array detector(More)
