Objective: To compare the dosimetry of IMRT versus 3DCRT in prostate cancer, with a focus on testicular dose using lead testicular shielding. Materials and Methods: From January 2021 to January 2022, twenty patients with localized prostate cancer underwent IMRT treatment. Plans for 3DCRT were generated for each patient. Comparison was made between...

Introduction The purpose of the study was to determine forward-planned intensity-modulated radiotherapy which improves the sparing of organs at risk (OAR), heart, lungs, and contralateral breast, when compared with multi-field inverse-planned intensity-modulated radiation therapy (RT). The anatomy of the chest wall is curved, which makes it difficu...

Rectal cancer is the second most common cancer in large intestine. Recently, preoperative chemoradiotherapy has been generally used in the management of locally advanced rectal cancer on the basis of several benefits proven by clinical studies, in the aspect of better locoregional tumor control, reduced toxicity of normal organs, and an increased c...

A BSTRACT Objective The recommended course of treatment for early-stage breast cancer is breast-conserving surgery followed by adjuvant whole-breast radiation. It is challenging to obtain homogeneous dose distribution using standard procedures because of breast irregularities. Currently, it is possible to use different breast irradiation technique...

Esophageal cancer (EC) is a common cancer with high mortality because of its rapid progression and poor prognosis. One of the most successful therapies for EC is radiotherapy. Two recently created radiation methods are intensity-modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy (3D-CRT). In terms of target coverage, dose ho...

A BSTRACT Aim and Objectives The study was conducted to to compare the dosimetric superiority between the Field in Field and Box techniques. Meterials and Methods We have taken 22 Patients of Ca esophagus for our study from our Institute database. Patients were already treated Box (4 fields) plan. Retrospectively additional Field in Field (FIF) p...

Purpose: To compare the dose distribution of three-dimensional conformal radiation therapy (3DCRT) with intensity-modulated radiation therapy (IMRT) for post-mastectomy radiotherapy (PMRT) to left chest wall. Materials and Methods: 30 post-MRM female breast cancer patients with histologically confirmed infiltrating ductal carcinoma of unilateral le...

Purpose: Intracavitary brachytherapy is one of the important methods of gynecological cancer treatment. The effect of attenuation is not considered in the dose calculation method released by the American Association of Physicists in Medicine (AAPM) Task Group No. 43 Report (TG-43). In this study, the effect of high-dose rate (HDR) brachytherapy ap...

Purpose The purpose of the current study is to determine whether patients diagnosed with glioblastoma multiforme (GBM) who underwent radiotherapy (RT) using intensity-modulated RT (IMRT) technique were benefitting from this highly conformal treatment in terms of doses received by planning target volume (PTV) and organs at risk (OARs) in comparison...

Occupational radiation doses for medical workers from the departments of diagnostic radiology, nuclear medicine, radiotherapy, cardiology, gastroenterology, radiological physics & BE and associated medical college of Sher I Kashmir Institute of Medical Sciences (SKIMS) Hospital were measured and analyzed. A total of 257 medical radiation workers we...

External beam radiotherapy is being used regularly to treat the breast malignancy postoperatively. The contribution of the collimator leakage and scatter radiation dose to contralateral breast is of concern because of high radio sensitivity of breast tissue for carcinogenesis. This becomes more important when the age of breast cancer breast patient...

The goal of the Radiation standards and Dosimetry is to ensure that the output of the Teletherapy Unit is within ±2% of the stated one and the output of the treatment dose calculation methods are within ±5%. In the present paper, we studied the dosimetry of Cobalt-60 (Co-60) Teletherapy unit at Sher-I-Kashmir Institute of Medical Sciences (SKIMS) f...

BACKGROUND: A primary consideration in any radiographic procedure is to reduce the dose to the patient and the operator while still achieving the diagnostic goals. OBJECTIVE: To study the radiation exposure and protective measures in different units of various hospitals in Kashmir valley in compliance to recommendations from regulatory authorities....
