Skin in vivo Dosimetry in Radiotherapy
Introduction: Due to the prevalence of skin problems in patients after radiotherapy, skin dose measuring is importance. Content: Skin in vivo dosimetry means measuring the patient's (or phantom) skin dose during radiotherapy. According to the ICRP 59, the dose at the depth of 0.07 mm is known as a skin dose. The most radiosensitive epidermis cells are located...
متن کاملContribution to the Determination of In Vivo Mechanical Characteristics of Human Skin by Indentation Test
This paper proposes a triphasic model of intact skin in vivo based on a general phenomenological thermohydromechanical and physicochemical (THMPC) approach of heterogeneous media. The skin is seen here as a deforming stratified medium composed of four layers and made out of different fluid-saturated materials which contain also an ionic component. All the layers are treated as linear, isotropic...
متن کاملIn vivo time-resolved autofluorescence measurements to test for glycation of human skin.
We present an evaluation of time-resolved fluorescence measurements on human skin for screening type 2 diabetes. In vivo human skin is excited with a pulse diode at 375 nm and pulse width of 700 ps. Fluorescence decays are recorded at four different emission wavelengths: 442, 460, 478, and 496 nm. Experiments are performed at various locations, including the palms, arms, legs, and cheeks of a h...
متن کاملارزیابی دقت زنجیره پرتودرمانی به روش دزیمتری in vivo
از بین بردن سلول های بدخیم با استفاده از تأثیر پرتو های یونساز بر بافت زنده یکی از موثرترین روش ها در درمان تومورهای سرطانی محسوب می شود. مبانی حفاظت پرتوی ایجاب می کند که هر نوع پرتو گیری توجیه پذیر و بهینه باشد. به علاوه برای کسب نتیجه درمانی مطلوب، باید موازنه دقیقی بین دُز رسیده به بافت هدف از یک سو و دُز رسیده به بافت سالم از سوی دیگر برقرار شود. کنترل واقعی درمان و آگاهی از آنچه در عمل رخ م...
15 صفحه اولAutologous Serum Skin Test versus Autologous Plasma Skin Test in Patients with Chronic Spontaneous Urticaria
Previous studies indicate that 25-45% of chronic urticaria patients have an autoimmune etiology. Autologous serum skin test (ASST) and autologous plasma skin test (APST) are simple tests for diagnosing chronic autoimmune urticaria (CAU). However, there are still some questions about the specificity of these tests. This study consisted of 50 patients with chronic spontaneous urticaria (CSU) and ...
