COBALT 60 TREATMENT FIELD VERIFICATION BY XERORADIOGRAPHY

Dose measurement of cobalt-60 radiotherapy beams in treatment fields.

BACKGROUND Radiation-therapy is a complex process with multiple steps, each of which has an impact on the quality of treatment. Accurate dosimetry is a critical step during the radiotherapy of cancer patients.The aim of the present study was to measure and evaluate the doses of two cobalt- 60 (60Co) teletherapy units GWXJ80 of NPIC China and Theratron 780 of AECL Canada at various points within...

Barc Develops Cobalt-60 Teletherapy Machine for Cancer Treatment

Human cancer is probably as old as the human race. For normal cells, the growth, division and death of cells occur in a controlled manner. Cancer cells on the other hand multiply in an uncontrolled way creating tumors. Tumors may replace healthy tissues and often start spreading to other parts of the body, leading to a lifethreatening situation. If untreated, most cancers lead to protracted suf...

Dosimetric Comparison of Various Radiotherapeutic Treatment Plans Using Cobalt-60 and Linac for Prostate Cancer

Introduction: This study was designed to evaluate dosimetric parameters such as rectal dose, bladder dose, integral dose (ID), homogeneity index (HI) and conformity index (CI) in various treatment plans for prostate cancer. Materials and Methods: Pelvic computed tomography (CT) scans of 27 patients were acquired and transferred to the RTDosePLAN treatment planning system. For each patient, 8 co...

Multicurie Cobalt 60 Units for Radiation Therapy.

Dosimetric Conformity of Cobalt-60 (Co) Beams

Objective: The radiation dosimetry is the output measurement of radiation generating source/ machine and its ambition is to ensure that the teletherapy units’ outputs are within limits. In the current article, the dosimetry of Cobalt-60 (Co 60 ) teletherapy units at Nuclear Institute of Medicine and Radiotherapy (NIMRA), Jamshoro Pakistan was studied. As Co 60 is undergo decay process, the outp...
