In this study, we aim to compare target tissue and critical organ doses in 3D-CRT and IMRT
plans in RT patients with early-stage left-sided breast cancer, which is receiving radiotherapy on the left chest wall.
It also includes functionality such as RaySearch's algorithms for IMRT
and VMAT optimisation and highly accurate dose engines for photon, electron, proton and carbon ion therapy.
Asif Jalai said that in Institute of Nuclear Medicine Oncology and Radiotherapy (INOR) Abbottabad we have introduced the state of the art Intensity-modulated radiation therapy (IMRT
) method with the cost of 300 million and it would start within one year as bunker facility for IMRT
is under construction with the cost of 75 million rupees.

and RA, the plans were designed to deliver in a single-phase process (with simultaneous integrated boost (SIB)).
Treatment plans were generated using 6MV photons with 2-4 arcs using volumetric modulated arc therapy, seven field IMRT
, or conventional radiotherapy.
Currently, in many locations, beam angle selection for IMRT
treatment planning is done simply by choosing equiangular spaced beams or through time-consuming trial and error based on the experience of the treatment planners.
* Nancy Mendenhall, MD of the University of Florida Proton Therapy Institute (UFPTI) compared results from 1,500 male prostate cancer patients in Florida and Arizona and found that for men who received proton therapy, the likelihood of survival with no evidence of a rise in PSA after five years was 94 percent compared to 87 percent of patients who had been treated with intensity-modulated radiation therapy (IMRT
enables doctors to give a high dose of radiation directly to cancer cells while protecting the surrounding healthy tissue, thereby cutting down on side-effects.
In the new study on 447 men, 71% of patients with prostate cancer were alive and also completely free from disease five years after treatment with IMRT
Implementation of the standard technique of IMRT
in the treatment of nasopharyngeal cancer has led to better conformity of the target volume and a reduced dose received by radiosensitive organs and especially by the parotid glands [3, 4].
