Dosimetric Consistency of Co-60 Teletherapy Unit- a ten years Study.
OBJECTIVE 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) for last 10 years. Radioactivity is th...
متن کاملDosimetric 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...
متن کاملA Specific Patient Quality Assurance (PSQA) procedure for a Co-60 source based High Dose Rate Brachytherapy
Introduction: In radiation therapy, accurate dose determination and precise dose delivery to the tumor are directly associated with better treatment outcomes in terms of higher tumor control and lower post radiation therapy complications. The current study aims the development and clinical application of the Patient Specific Quality Assurance (PSQA) procedures for nasopharyngea...
متن کاملQuality control of blood irradiation with a teletherapy unit: damage to stored red blood cells after cobalt-60 gamma irradiation.
BACKGROUND Previous publications have documented the damage caused to red blood cells (RBCs) irradiated with X-rays produced by a linear accelerator and with gamma rays derived from a 137Cs source. The biologic effects on RBCs of gamma rays from a 60Co source, however, have not been characterized. STUDY DESIGN AND METHODS This study investigated the effect of 3000 and 4000 cGy on the in vitro...
متن کاملQuality control system for blood irradiation using a teletherapy unit.
BACKGROUND AND OBJECTIVES Irradiation of whole blood and blood components before transfusion is currently the only accepted methodology to prevent transfusion-associated graft-vs.-host disease. In the present work, we developed an automated system for blood bag storage during irradiation, using a teletherapy unit. MATERIALS AND METHODS A device with two thermal compartments was constructed in...
