In a study comparing the responses of institutionalized Down's syndrome (DS) and non-Down's (ND) inmates to enterovirus infections, the frequency of wild enteric viruses and the excretion patterns of oral polio vaccine (OPV) viruses were similar in both groups. Antibody titres developed to poliovirus types 2 and 3 following vaccination were similar in DS(More)
PURPOSE Advanced treatment delivery techniques require more robust treatment planning system (TPS) models for accurate dose planning and computation. As stereotactic body radiation therapy (SBRT) and volumetric-modulated arc therapy (VMAT) treatments become more prevalent, the ability of the TPS to accurately calculate dose delivered from small fields(More)
PURPOSE There are multiple factors that have lead to the need for an increased precision and accuracy in Radiation Therapy. The increased use of IMRT and SBRT with hypofractionated doses requires optimal precision and accuracy in aligning the treatment delivery with the target. Recent advances in imaging and motion management of patients during the(More)
PURPOSE The purpose of this study was to compare dosimetric parameters of treatment plans between coplanar and non-coplanar techniques for treating peripheral lung lesions. METHODS The planning CT scans of 6 patients in supine positions were used in this study. The size of the PTV ranges from 163 c.c. to 782 c.c.. The locations of PTV are mostly at the(More)
