Thesis Discussion<\/h1>\n

College of science for women\/University of Baghdad examined the thesis entitled (Effect the Uncertainties on the Images of Radiation Dose of Linear Accelerator)<\/p>\n

of the student: Zainab Abd AL-Qader Mohammed.<\/strong><\/p>\n<\/div><\/div><\/div>

Objectives of the thesis<\/div><\/span>
[vc_column_text css=””]The thesis aims to receive accurate treatment for cancer patients who are treated with radiation from the linear accelerator device, the patient is admitted to the spiral CT scanner room, placed in a position where he is positioned and aids are used to achieve the best stable position without movement. The doctor then draws the tumor area and the surrounding critical organs and determines the appropriate radiation dose. After that, the physicist creates a treatment plan in terms of the number of radiation beams and the angles of their entry into the tumor, as 95% of the radiation dose must be delivered to the tumor area and a lower dose to the surrounding critical organs. The patient is then entered into the linear accelerator device, where he fixes himself and his position in the CT room. The difference between the image coming from the physics and the portal image in the device is calculated. If the difference between the two images is within the permissible range, the patient is treated.[\/vc_column_text]<\/div><\/div>
<\/i>
Content of the thesis<\/div><\/span>
[vc_column_text css=””]The thesis also includes the setup error in the linear accelerator, which is the difference between the actual treatment image represented by the portal image and the digitally reconstructed x-ray image coming from the physical planning, which is the reference image (DRR). To increase the life expectancy of head and neck, breast, and pelvic cancer patients, the efficiency and accuracy of radiotherapy delivery are critical factors in terms of cancer suppression and the dose received by critical organs.[\/vc_column_text]<\/div><\/div>
<\/i>
thesis recommendations<\/div><\/span>
[vc_column_text css=””]The most important recommendations which the study has come up with and the average obtained. The using X-ray volumetric imaging (XVI) system gives image cone-beam computerized tomography (CBCT) which is a three-dimensional image. Whereas the XVI can show the critical organs, such as the lungs in breast cancer, Also the bladder, and the rectum in pelvic cases. And to reduce the systematic and random errors. XVI should be taken daily.[\/vc_column_text]<\/div><\/div>

Final estimate<\/div><\/span>
[vc_column_text css=””]Final Grade: Excellent.[\/vc_column_text]<\/div><\/div>
