Download or read book Radiation Therapy for Skin Cancer written by Armand B Cognetta and published by Springer Science & Business Media. This book was released on 2013-06-13 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photon Radiation Therapy for Skin Malignancies is a vital resource for dermatologists interested in radiation therapy, including the physics and biology behind treatment of skin cancers, as well as useful and pragmatic formulas and algorithms for evaluating and treating them. Dermatology has always been a field that overlaps multiple medical specialties and this book is no exception, with its focus on both dermatologists and radiation oncologists. It is estimated that between 2010 and 2020, the demand for radiation therapy will exceed the number of radiation oncologists practicing in the U.S. tenfold, which could profoundly affect the ability to provide patients with sufficient access to treatment. Photon Radiation Therapy for Skin Malignancies enhances the knowledge of dermatologists and radiation oncologists and presents them with the most up-to-date information regarding detection, delineation and depth determination of skin cancers, and appropriate biopsy techniques. In addition, the book also addresses radiation therapy of the skin and the skin’s reactions to radiation therapy.
Download or read book Radiological Dose Assessment - Nonuniform Skin Dose, Radioactive Skin Contamination, and Multiple Dosimetry written by and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Radioactive skin contamination with [beta]- and [gamma]-emitting radionuclides may result in biologically significant absorbed doses to the skin. A specific exposure scenario of interest is a nonuniform skin dose delivered by [beta]- and [gamma]-emissions from radioactive skin contamination. The United States Department of Energy requires a formal evaluation and reporting of nonuniform skin doses. The United States Department of Energy also requires specific, formal procedures for evaluating the results from the placement or use of multiple dosimeters. Action levels relative to potential absorbed doses for the contamination survey instrumentation in use at Los Alamos and formal procedures for evaluating nonuniform skin doses and multiple dosimeters are developed and presented here.

Download or read book Skin Depth Dose Distribution Measurement and Analysis Using Radiochromic Dosimetry written by Kellen K. Thuo and published by . This book was released on 2011 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compliance with 10CFR 20.101 requires that exposure to the skin be assessed at a depth of 0.007 cm over 10 cm2 area. This depth generally corresponds to the interface between the epidermal and dermal layers of the skin. The Nuclear Regulatory Commission states the criteria for evaluating skin dose from hot particle contamination at specific skin depths and sets dose limits for such exposure. In this work, GafChromic® external beam therapy (EBT) film, a near tissue equivalent film is simulated to represent skin. Monte Carlo N Particle simulations and experiments using various radiation sources are conducted at shallow depth for skin dosimetry. The results are compared to VARSKIN 4, a computational skin dose calculator. Accurate measurements using the radiochemical dosimeter will provide a fast, practical application of measuring skin dose at shallow depths over a wide range of energy sources. In the future, the film can be used in designing protective clothing for radiation workers as it is cost effective, highly sensitive to radiation and easy to work with.

Download or read book Thermoluminescence Sheet-type Dosimeter for in Vivo Skin Dosimetry in Passive Scattering Proton Therapy written by Takahiro Kato and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose; Considering skin sparing is important in passive scattering proton therapy (PSPT), in which small number of fields may cause high entrance dose. In vivo skin dosimetry (IVSD) is desirable to perceive actual skin dose, however, the methodology of IVSD in PSPT has not yet been established so far. Newly developed thermoluminescence sheet-type dosimeters (TLSD) are particularly suited for applications in IVSD because of their ease of use, and capability of adjusting size. We investigated the utility of TLSD for IVSD in PSPT.Materials and Methods; Lithium triborate (effective atomic number 7.3) is the main component of TLSD (TOYO Medic Ltd., Tokyo, Japan). To evaluate the basic characteristics for proton beams such as dose linearity, uniformity, and energy dependences, unmodulated and modulated proton beams are irradiated to TLSD in parallel or perpendicular to the beam axis in the custom-made water phantom. Furthermore, to measure the actual range shift of the proton beam due to TLSD insertion in the bean line, the proton depth-dose curve measurements were obtained to determine water equivalent thickness (WET) with or without TLSD attached to the entrance wall of the water phantom.Results; The dose response was found to be linear up to 10 Gy. The percent depth-dose and dose profile measured with TLSD well reproduced the results with ionization chamber. The WET without protective sheet was estimated to be approximately 0.2 mm.Conclusion; Although there are some needs for improvement, the impact on range error is almost negligible in IVSD, new TLSD is suitable to be used as IVSD tools in PSPT.

Download or read book Dosimeter for Measuring Skin Dose and More Deeply Penetrating Radiation written by and published by . This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A personnel dosimeter includes a plurality of compartments containing thermoluminescent dosimeter phosphors for registering radiation dose absorbed in the wearer's sensitive skin layer and for registering more deeply penetrating radiation. Two of the phosphor compartments communicate with thin windows of different thicknesses to obtain a ratio of shallowly penetrating radiation, e.g. beta. A third phosphor is disposed within a compartment communicating with a window of substantially greater thickness than the windows of the first two compartments for estimating the more deeply penetrating radiation dose. By selecting certain phosphors that are insensitive to neutrons and by loading the holder material with netruon-absorbing elements, energetic neutron dose can be estimated separately from other radiation dose. This invention also involves a method of injection molding of dosimeter holders with thin windows of consistent thickness at the corresponding compartments of different holders. This is achieved through use of a die insert having the thin window of precision thickness in place prior to the injection molding step.

Download or read book Skin Contamination Dosimeter written by and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A technique and device provides absolute skin dosimetry in real time at multiple tissue depths simultaneously. The device uses a phoswich detector which has multiple scintillators embedded at different depths within a non-scintillating material. A digital pulse processor connected to the phoswich detector measures a differential distribution (dN/dH) of count rate N as function of pulse height H for signals from each of the multiple scintillators. A digital processor computes in real time from the differential count-rate distribution for each of multiple scintillators an estimate of an ionizing radiation dose delivered to each of multiple depths of skin tissue corresponding to the multiple scintillators embedded at multiple corresponding depths within the non-scintillating material.
