Bremsstrahlung interactions, the primary source of x-ray photons from an x-ray tube, are produced by the sudden stopping, breaking or slowing of high-speed electrons at the target. When the electrons from the filament strike the tungsten target, x-ray photons are created if they either hit a target nucleus directly (rare) or their path takes them close to the nucleus. If a highspeed electron hi...

X-rays generated at a kilovoltage of 250 have been used in the treatment of malignant disease for about 30 years. It was found that when high doses were given, damage to the skin and subcutaneous tissues was frequent. After desquamation of the skin had subsided, pigmentation followed and during the succeeding i8 months permanent and unsightly telangiectasis developed. This was often associated ...

Objective(s): The current systematic study has reviewed the therapeutic potential of gold nanoparticles as nano radiosensitizers for cancer radiation therapy. Materials and Methods: This study was done to review nano radiosensitizers. PubMed, Ovid Medline, Science Direct, SCOPUS, ISI web of knowledge, Springer databases were searched from 2000 to September 2013 to identify appropriate studies. ...

This article shows the development of an instrument for measuring exposure parameters used to take radiographic studies in living beings; such as kilovoltage, current and time, since radiation protection is a fundamental pillar care patients operators ionizing equipment, it necessary calibrate these equipment that produce X-rays. For manufacture ESP32 microcontroller which programmed using Pyth...

The advent of kilovoltage cone-beam computed tomography (CBCT) integrated with a linear accelerator allows for more accurate image-guided radiotherapy (IGRT). The IGRT technique corrects target displacement based on internal body information obtained by acquiring the CBCT image set and registering it with the simulation CT image set just before the beam is delivered. In the present paper, we co...

The use of Cone-beam Computed Tomography (CBCT) in radiotherapy is increasing due to the widespread implementation of kilovoltage systems on the currently available linear accelerators. Cone beam CT acts as an effective Image-Guided Radiotherapy (IGRT) tool for the verification of patient position. It also opens up the possibility of real-time re-optimization of treatment plans for Adaptive Rad...
