A Simple Form of Influence Machine for X-Ray Work
نویسنده
چکیده
To get X-rays out of a suitable vacuum tube, it needs to be excited by an electric discharge at a tension of hundreds of thousands of volts. Such a discharge is furnished by the induction coil and by the static induction or " influence" machine, associated in its most elegant and effective form with the name of Mr. Wimshurst. In spite of the obvious advantages of the latter type of machine over the former, very little systematic X-ray work with the influence machine has appeared; and the greater number of the textbooks of radiography pass the matter over with a general statement that the

Evaluation of a systemic change of Superficial X-ray tube characteristics
Introduction: Very low, Low and Medium X-ray machines are used extensively for Superficial Radiation Therapy mostly used for Basal Cell, Squamous Cell Carcinoma, and Melanoma skin cancers. In most of cases, Superficial X-ray Therapy (SXRT) is preferred to Electron beams generated using a linear accelerator. SXRT tube characteristics may vary with the use of the machine for a lo...
متن کاملImpact of quality control on radiation doses received by patients undergoing abdomen X-ray examination in ten hospitals
ABSTRACT Background: The X-ray machines used for radiodiagnosis should meet certain quality assurance (QA) programmes . These are necessary to have good quality radiographs at reasonably low exposure to patients. Materials and Methods: Dose reduction methods in abdomen X-ray examination were carried out in 10 hospitals in Tehran. This paper presents the work, which was implemented on 200 ...
متن کاملDoses Received by Patients during Thorax X-Ray Examinations
Introduction Radiation exposures from diagnostic medical examinations are generally low and are almost always justified by the benefits of accurate diagnosis of possible disease conditions. Therefore, entrance skin dose (ESD), body organ dose (BOD), and effective dose (ED) from adult patients undergoing routine thorax posterior-anterior (PA) and thorax right lateral (RLAT) were estimated in Uni...
متن کاملLevel of exposure to X-Ray in security gates of Tehran’s Imam Khomeini airport
X-Ray is an ionizing electromagnetic radiation with a wide spectrum. A setting where this radiation is widely used is airport security units. This study was conducted to measure the level of momentary exposure to X-Ray in operators and personnel working in security gates of Imam Khomeini airport. In this cross-sectional study, the X-Ray machines used in security gates of Imam Khomeini airport a...
متن کاملHVL evaluation of orthovoltage X-ray machine using EGSnrc code of simulation
Background: Making use of the orthovoltage machines in Radiotherapy, is one of the routine methods for the treatment of the superficial lesions. In this study, an important determinant of X-ray quality, the HVL (Half Value Layer), has been evaluated. Materials and Methods: The HVLs of a orthovoltage X-ray machine in 120 and 180 kVp are measured, using an empirical method, in which the HVLs are ...
