The monitor unit (MU) was calculated by pencil beam convolution (inhomogeneity correction algorithm: batho power law) [PBC (BPL)] which is the dose calculation algorithm based on measurement in the past in the stereotactic lung irradiation study. The recalculation was done by analytical anisotropic algorithm (AAA), which is the dose calculation algorithm(More)
In postoperative radiotherapy for seminoma, control of the testicular absorbed dose is important, since exposure of the testis can lead to temporary or permanent infertility. In this case, instead of using a dog-leg-shaped field, treatment using a field focused near the aorta was provided in several disease stages of seminoma. However, the precise need for(More)
The purpose of this study was to verify the dose absorbed by an implantable cardioverter defibrillator (ICD) from an (192)Ir sealed source during uterine intracavitary brachytherapy, and to confirm its immunity to radiation effects. First, prior to treatment, the doses around the ICD position of an anthromorphic phantom were evaluated. Next, we also(More)
Boron-moiety-containing aluminoxanes (BMAOs) were prepared from the partial protonolysis of Me3Al using various arylboronic acids. Compared with methylaluminoxane (MAO) generated from the hydrolysis of Me3Al, BMAO prepared from C6F5B(OH)2 and Me3Al induced a higher activity at the same Al/Ti ratio in the Ti-based olefin polymerization catalyst(More)
We previously studied dose distributions of stereotactic radiotherapy (SRT) for lung cancer. Our aim is to compare in combination pencil beam convolution with the inhomogeneity correction algorithm of Batho power low [PBC (BPL)] to the anisotropic analytical algorithm (AAA) by using the dose evaluation indexes. There were significant differences in D95, PTV(More)
PURPOSE The purpose of this study was to evaluate the effect of prostate matching on dose distribution using kilovolt cone beam computed tomography (kV-CBCT) with image guided radiation therapy for prostate cancer. MATERIALS AND METHOD Sixteen prostate cancer patients were treated with intensity modulated radiation therapy to 76 Gy at 2 Gy per fraction in(More)
We determined the nucleotide sequences of cDNA clones and part of a genomic clone for the DQwl~ gene from the HLA-Dw12 haplotype. The sequencing analysis revealed that the DQwle gene from Dw12 is organized in six exons, as is the mouse A;~ gene. Moreover, one cDNA clone which lacked a region corresponding to exon 5 and potentially encoding a smaller DQ~(More)
