Abstract This work presents a unique non-invasive method for monitoring glucose levels in blood using planar Yagi–Uda antenna as microwave sensor. The proposed antenna, operating at 5.5 GHz, exhibits directional radiation pattern with peak gain of 6.74 dBi. A low-cost FR4 material size 30 mm × 40 1.6 is used dielectric substrate. human finger phantom, comprising layers skin, fat, blood, and bon...

This article explores the phenomenon of "phantom pain." The analysis is based on personal experiences elicited from individuals who have lost a limb or live with a paralyzed body part. Our study reveals that the ways in which these individuals express their pain experience is an integral aspect of that experience. The material consists of interviews undertaken with men who are living with phant...

Introduction: In patients with thyroid carcinoma, radiation absorbed doses of the thyroid and surrounding tissues is important to weigh risk and benefit considerations. In nuclear medicine, the accuracy of absorbed dose of internally distributed radionuclides is estimated by different methods such as MIRD and direct method using TLD. The aim of this study is using TLD and a phantom to determine...

PURPOSE The radiation dose to the lens of the eye, skin, thyroid and brain of patients who underwent diagnostic and interventional radiological procedures of the lacrimal drainage system have been measured with thermoluminescent dosimeters (TLD-100 and TLD-700) by using an adult male and female Rando phantom. All dose values for one second of fluoroscopic exposure and one frame of digital subtr...

Recent research based on numerical modeling (Bond, 2003; Xu, 2001) that ignored hardware characteristics and simple experiments using homogenous breast phantoms (Sill, 2005; Xu, 2004) have shown the potential of ultra-wideband to detect early stage breast cancer. However, clutter interference from heterogeneous breast tissues and hardware characteristics like pulse jitter, finite dynamic range ...

Up to 80% of amputees report phantom limb pain (PLP), the management of which remains a considerable challenge. Here I describe the successful treatment with scalp acupuncture (SA) of a woman with PLP. A 71-year-old woman with no significant medical history was injured in a road-traffic accident in January 2010, leaving her with a fracture of the right elbow and right scapula, and multiple lace...

Entrance skin dose (ESD) is an important parameter for assessing the dose received by a patient in a single radiographic exposure. The most useful way to evaluate ESD is either by direct measurement on phantoms using an ionization chamber or using calculations based on a mathematical model. We compared six phantoms (three anthropomorphic, two physical, and one mathematical) in 11 standard clini...

Glioblastoma multiforme (GBM) is the most common, aggressive, highly malignant and infiltrative of all brain tumors with low rate of control. The main goal of this work was to evaluate the spatial dose distribution into a GBM simulator inside a head phantom exposed to a 15 MV 3D conformal radiation therapy in order to validate internal doses. A head and neck phantom developed by the Ionizing Ra...
