A telecobalt60-computed radiography verification model to improve the certainty of the irradiation

Radiotherapy remains the main treatment of cancer to date. To achieve the certainty of the irradiation, the radiotherapy must be delivered using teletherapy, which is equipped with a verification portal imaging device. However, the telecobalt60 is not equipped with the verification portal imaging de...

To achieve the certainty of the irradiation, the radiotherapy must be delivered using teletherapy, which is equipped with a verification portal imaging device. However, the telecobalt60 is not equipped with the verification portal imaging device. Therefore, in the telecobalt60 utilization, the wrong site being treated errors in radiotherapy delivery are rarely verified. To solve this issue, this study aimed to determine the factors that could influence the telecobalt60-computed radiography verification model to improve the certainty of the irradiation, to develop the telecobalt60- computed radiography verification model, to formulate the standard of procedures (SOP) of the telecobalt60-computed radiography verification model, and to improve the certainty of the irradiation by existing and performing the SOP of the telecobalt60-computed radiography verification model and compare with the previous SOP of the irradiation. The research design was a mix of qualitative and quantitative methods. A qualitative study was used to determine the factors that could influence the telecobalt60-computed radiography verification model, to develop the telecobalt60-computed radiography verification model, and to formulate the SOP of the telecobalt60-computed radiography verification model. Meanwhile, a quantitative study was used to improve the certainty of the irradiation by performing the SOP of the telecobalt60-computed radiography verification model. Based on the results, the factors that could influence the telecobalt60-computed radiography verification model are the equality of the irradiation field (the scheme of simulator image, body size of the patient, and the patient positioning) and accuracy of the irradiation target factors (the set-up of the patient and teletherapy device, calibration of the teletherapy, quality of conducting the human resource, mechanical malfunctioning of the teletherapy). In developing the telecobalt60-CR verification model, formulating the SOP of the telecobalt60-CR verification model, and evaluating the improvement by the SOP of the verification model, there was significant (p<0.05) improvement of the certainty of the irradiation by existing and performing the SOP of the telecobalt60-computed radiography verification model as compared to the previous SOP of the irradiation. The conclusion was the equality of the irradiation field and accuracy of the irradiation target factors significantly (p<0.05) influenced the telecobalt60-computed radiography verification model to improve the certainty of the irradiation. The certainty of the irradiation obtained by the verification model performed by the SOP of the telecobalt60- computed radiography verification model was improved as compared to the previous SOP irradiation.
