BSci, MAppSci (Medical Physics)
Ceren is an experienced medical physicist and is particularly interested in the diverseness of the profession. She has a keen mind towards all aspects of physics and applies her knowledge to healthcare.
Ceren completed her Masters in medical physics project on the development and validation of an optical simulation of tumour movement monitoring during radiotherapy. The research project specifically addressed the issue of image guide radiation therapy: particularly associated with monitoring of tumour movement during actual delivery of external beam radiation therapy (intra fraction). It also considered the application of novel quantitative real-time ultrasound imaging, the specific aim being to dynamically monitor tumour movement during actual external beam radiotherapy delivery using a robotically-controlled ultrasound system.

Nazia graduated with bachelors in Physics and a Masters in Applied Sciences (Medical physics) from Queensland University of Technology. Her research revolved around the validation of small field detectors that included the W2 scintillator detector, Diamond detector, RAZOR nano chamber and CC01 in small field dosimetry using Monte Carlo simulation (EGSnrc and DOSXYZnrc).
Nazia is interested in science, especially Medical Physics and wants to explore the application of physics to improve human life. She thinks the current developments in Physics are overwhelming and open-up opportunities for the younger generation to delve into and use for the benefit of human beings. She is keen to explore the application of the theories to everyday life and improve living standards.

She actively participated in helping accomplish the balance of diagnostic image quality and radiation dose in close collaboration with physicians, technologists, and technical staff during her internship at Wollongong Hospital. Almost all of the equipment used by the clinicians in today’s hospitals and clinics are designed and put into clinical practice by medical physicists and clinical engineers, so, physicists offer reliability and continuity in medical physics services worldwide. In her work with Sieverts Rajdeep is interested in exploring the radiation safety programs and pathways, from radiation safety to compliance testing, to ensure the safe and effective use of radiation sources for both the public and staff working in these environments.
Jackie is a medical physicist with many years of experience in radiation compliance and safety.
Jackie completed her Masters project titled: Feasibility study of the use of an Electronic Portable Imaging Devices (EPID) Dosimetry Calibration Compensator. The project was to develop and verify a mean to maintain a correction in pixel variation without correcting beam profile in electronic portal imaging device with Monte-Carlo simulation using EGSnrc and DOSEXYZnrg.
As a medical physicist, Jackie continues to develop her experience in radiation protection, dose optimisation and radiation therapy – treatment and pre-treatment dose verification.
Esther graduated with a Bachelor of Medical Radiation Physics and a Masters of Philosophy in Medical Radiation Physics from the University of Wollongong, NSW.
Esther’s thesis considers the Impact of 4DCT Dataset Representation on Radiotherapy Dose Calculations. It focused on how using different methods of reconstructing 4DCT datasets affected treatment planning and dose calculations for a moving tumour within the body. eg: lung tumours.
As a medical physicist, she is particularly interested in the innovative techniques used in cancer treatment that require little or no invasive surgical procedures to treat cancers such as Stereotactic Body Radiation Therapy (SBRT), which is a method of using medical imaging techniques to locate and target cancers with highly precise radiation treatment.
Daniel is a medical physicist with a keen interest in diagnostic and therapeutic nuclear medicine imaging. He has a strong working knowledge of radiation safety compliance program to ensure public safety.
Daniel completed his Masters research on Monte Carlo simulation to Relative Biological Effectiveness (RBE) weighted dose for 50 kV therapy.
Sypnosis – RBE of low energy x-rays have been found to have a higher RBE than x-rays in the megavoltage range. The research project investigated the relative biological effectiveness of a 50 kVp beam used for superficial and intraoperative therapy. It was found by a combination of physical measurements and Monte Carlo simulations that the 50 kVp beam produced has an RBE greater than unity relative to a Co-60 beam.
