We validated 3D radiochromic film dosimetry for volumetric modulated arc therapy (VMAT) using a newly developed spiral water phantom. The phantom consists of a main body and an insert box, each of which has an acrylic wall thickness of 3 mm and is filled with water. The insert box includes a spiral film box used for dose-distribution measurement, and a film holder for positioning a radiochromic...

The effect of super atmospheric O2 and modified atmosphere packaging (MAP) on plant metabolism, organoleptic quality and microbial growth of minimally processed baby spinach was studied. Packaging film O2 transmission rates and initial levels of super atmospheric O2 in the packages significantly affected the changes of in-package atmospheres during storage, and consequently quality of baby spin...

The photo-induced alignment quality of a ferroelectric liquid crystas (FLC) onto a photochemical stable azodye film was studied for various procedures of the azodye film photo-treatment and the FLC structure. The alignment quality of FLC depends mainly on the order parameter of the azodye film, however the structure of FLC layer is also important. So, the photo-aligned deformed helix ferroelect...

Diquafosol is a drug used for dry eye treatment with a novel mechanism of action. It stimulates the secretion of tear fluid and mucin on the ocular surface, thus enabling us to selectively treat the tear film layer, playing an important role in the establishment of the concept of "Tear Film Oriented Therapy (TFOT)", an effective therapeutic approach to dry eye in Japan. The 3% diquafosol ophtha...

A novel phantom is presented for 'full system' dosimetric audit comparing planned and delivered dose distributions in HDR gynaecological brachytherapy, using clinical treatment applicators. The brachytherapy applicator dosimetry test object consists of a near full-scatter water tank with applicator and film supports constructed of Solid Water, accommodating any typical cervix applicator. Film d...

PURPOSE To assess agreement between evaluations of monoscopic and stereoscopic digital images versus stereo film photographs in diabetic macular edema (DME). METHODS A 152-eye group of digital monoscopic macular images (seven-field sets and wide-angle mosaics) were compared with digital stereoscopic images (uncompressed and compressed seven-field sets) and stereo 35-mm film photos (Early Trea...

introduction: gafchromic ebt films are one of the self-developing and modern films commercially available for dosimetric verification of treatment planning systems (tpss). their high spatial resolution, low energy dependence and near-tissue equivalence make them suitable for verification of dose distributions in radiation therapy. this study was designed to evaluate the dosimetric parameters of...

a simple method for fabrication of highly ordered gold nanorod film is introduced in this article. the procedure is based on thermal evaporation of gold into a porous anodic alumina film (paa). the ppa film was fabricated by combining the hard and mild anodization. this combination effectively decreases the processing time of fabrication of highly ordered porous anodic alumina film with control...
