Small electron field is a preferential choice of the oncologists in case of the treatment of small superficial lesions (scars). Small field electron dosimetry is necessary to perform prior to the treatment to assure the accuracy of the dose delivery. The main objectives of this work is to acquire small field electron dosimetric data with narrow circular cutouts and to develop the graphical user interface...
Modern radiotherapy depends largely on accurate dose delivery to the given target volume. Before going into clinical use, the calibration of the photon and electron beams produced by radiotherapy machine has to be done. The overall accuracy in tumor dose delivery should be below 3 percent. But on an evaluation of errors in dose delivery in a clinical setting, to achieve this accuracy is not an easy...
An innovative design of 16-channel front-end electronics for ionization chamber in monitoring proton beam profile has been developed to feature simplicity, low cost, durability, and reliability without compromising its performances. All the parts are available off the shelf. The front-end electronics board is powered by USB connection, through which the data are transferred to the host computer for...
