Analysis of Point Doses to Bladder and Rectum in HDR Brachytherapy to Advanced Cervical Cancer at Apeksha Hospital Maharagama
Wickramage, IS; Jayasinghe, VL; Weerasinghe, WNACO; Ramanathan, V; Rasnayake, S; Wickramasinghe, WMIS (2022)Gynaecological cancers are fourth commonest cancer in world among women. Brachytherapy is a major treatment option for gynaecological cancers. When Brachytherapy source is implanted in cervical cavity of the patient, ... -
Assessing Occupational Radiation Exposure for PET/CT Technologists: A Study of Finger Radiation Dose at a Selected Hospital
Gamage, SP; Ramanathan, V; Tudugala, R (2023-09)In nuclear medicine, radiation exposure to the ngers is a matter of concern for radiation workers since they perform the preparation, dispensing and administration of radiopharmaceuticals. Therefore, this study aims to ... -
Assessing Occupational Radiation Exposure in Interventional Cardiology: A Study on effective Dose Estimation
Wickramasinghe, HNSU; Ramanathan, V; Sarasanandarajah, S (2023-09)Safeguarding of safety and well-being of interventional cardiology healthcare workers, monitoring their occupational radiation exposure is crucial. This study evaluates the radiation dose of interventional cardiologists ... -
Assessment of Eye Lens Dose in Interventional Cardiology
Wickramasinghe, HNSU; Ramanathan, V; Sarasanandarajah, S (2022)The International Commission on Radiological Protection decreased the annual eye lens dose limit to 20 mSv in 2011 from the recommended value of 150 mSv in 2007 to reduce radiation-induced lens opacity in radiation workers ... -
Assessment of Setup-errors in 3D-Conformal Radiotherapy for Head and Neck Cancer Patients using an Electronic Portal Imaging Device
Karunathilaka, UIU; Ramanathan, V (2023-09)The accuracy in radiotherapy is very important since it is irreversible treatment and it partially depends on patient’s set up on each fraction of treatment. Developing unique margins by assessing set up errors will ... -
Brachytherapy in Cervical Cancer: Accuracy in Point Dose Demarcation
Gulawita, MS; Kumari, MPOT; Rasnayake, SL; Jayasuriya, KMGS; Ramanathan, V (2021)Brachytherapy dose specification point A, located 2 cm superior to the external cervical orifice and 2 cm lateral to the cervical canal, is a geometrical concept that represents the anatomic position where the uterine ... -
Determination of the Scatter Dose Received by Thyroid Region during Chest Wall Irradiation among Breast Cancer Patients Who Received Adjuvant Two Dimensional Conventional Radiotherap
Kumara, WAIU; Sawandi, LPM; Weerakoon, WMAKB; Ramanathan, V; Jeyakumaran, N; Tudugala, R (2021)Breast cancer is the most frequent cancer among women, and radiotherapy plays a major role in the treatment of breast cancer. The significant amount of scatter dose to the thyroid region during adjuvant radiotherapy ... -
Development of Institutional Reference Level of Radiation Dose for Cardiac Catheterization Procedures
Sigera, MPII; Ahamed, MFA; Ramanathan, V; Athokorala, TD (2023-09)Fluoroscopy-guided interventional procedures have gained prominence in diagnostic and therapeutic settings due to their minimally invasive nature. Among these procedures, Coronary Angiogram (CAG) stands out as one of the ... -
Establishment of Facility Reference Level for Computed Tomography in Radiotherapy Simulation Examinations at National Cancer Institute Sri Lanka
Athukorala, ADAD; Ramanathan, V; Jayathissa, RMGCSB (2023-09)Computed Tomography (CT) plays a crucial role in radiotherapy treatment planning. The optimization of radiation dose to patient during CT simulation is not a matter of concern so far in most of the countries but it cannot ... -
Establishment of Institutional Diagnostic Reference Levels for Whole-body Positron Emission Tomography/Computed Tomography Imaging Procedures
Adikari, AMLN; Ramanathan, V; Tudugala, R (2023-09)The use of Positron Emission Tomography/Computed Tomography (PET/CT) imaging has become more popular in oncology. A concern with PET/CT is the combined radiation doses from both CT and radiopharmaceuticals. A Diagnostic ... -
Evaluation of Setup Errors in Three-dimensional Conformal Radiotherapy (3D-CRT) for Pelvic Sites by Using Electronic Portal Imaging Device (EPID)
Gunarathne, KACM; Sampath, DC; Rizwy, MM; Ramanathan, V (2021)The setup error is defined as any deviation between the intended and actual treatment position, and it is determined by measuring the shift of the treatment field position by comparing the treatment image against its ...
