PhD Scholarship in Medical Science in Vivo Dosimetry for Radiation Therapy

A fully-funded PhD fellowship in computer science is available at University of Gothenburg. The funding allows successful candidate to work for four years. Applications should be sent before June 17, 2019.

Doctoral student in Medical Science – In vivo dosimetry for radiation therapy

Third-cycle studies are equivalent to four year full-time and lead to a Degree of Doctor. Those appointed to doctoral studentships shall primarily devote themselves to their studies. Those appointed to doctoral studentships may, however, work to a limited extent with educational tasks, research and administration. Before a PhD degree has been awarded,duties of this kind may not comprise more than 20 per cent of a full-time post.

The PhD educationin Medical Science comprisecarrying out a scientific project and completing at least 30 credits of courses at third-cycle level. The doctoral student must also write a scientific compilation thesis or monograph corresponding to at least 120 credits. For more information about third-cycle studies at Sahlgrenska Academy, see https://medarbetarportalen.gu.se/sahlgrenskaakademin/forskarutbildning/languageId=100001

Project: The ultimate goal with external radiation therapy is to eradicate tumor cells while sparing healthy tissue. The treatment is carefully planned for each patient by simulating the beam delivery and optimizing the irradiation technique and the resulting dose distribution. Available irradiation techniques rapidly evolve improving beam modulation and precision. VMAT (Volumetric Modulated Arc Therapy) facilitates an advanced dynamic beam delivery. Because of its complexity, thorough validation of the accelerator performance and the predicted dose is carried out before each treatment course. Performing in vivo dosimetry is an issue of particular importance because it would allow estimation of the delivered dose for improving the quality control and opening possibilities for adaptive therapy. The Electronic Portal Imaging Device (EPID), traditionally used for patient positioning, shows potential to become an in vivo dosimetry system. More investigation is needed to gain knowledge about EPID dose response and accuracy.

The overall project goal is to develop and implement in vivo dosimetry system for VMAT using EPID. In particular, the goal is to investigate EPID response to irradiation transmitted through the patient and its sensitivity to patient mispositioning and anatomy changes. Furthermore, the goal is to develop and validate a method for cumulative estimation of the 3D delivered dose to the patient based on EPID measurements.

The Monte Carlo method will be used as a reference method for particle transport and energy deposition simulated from first principles. The accelerator and EPID will be modelled in the EGSnrc code package using technical specification data. Patient anatomy will be based on computer tomography scans. Mathematical methods like back projection method will be involved in the 3D dose reconstruction. Appropriate validation measurements, e.g. by ionization chamber, film or other detectors, will be carried out. To be eligible for third-cycle studies, the applicant must meet both the general and specific entry requirements.

for third-cycle studiesif he or she:

1. has been awarded a second-cycle qualification 2. has satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second-cycle, or 3. has acquired substantially equivalent knowledge in some other way in Sweden or abroad for third-cycle studiesin Medical Science if he or she: has successfully completed the English B/6 course or is considered to have acquired equivalent knowledge through previous studies

In selecting between applicants who meet the general and specific entry requirements, their ability to benefit from third-cycle studies shall be taken into account. The assessment shall attach particular importance to documented qualifications for:

– specific knowledge and skills within the subject area and related research fields – experience of scientific theory and relevant research methodology – scientific analysis and presentation verified through thesis, degree project, scientific journals or the like. Documented knowledge in physics with a focus on medical physics or computer science is desirable. Experience of Monte Carlo simulations, programming and use of large software packages such as EGSnrc are merit.

After admission tothird-cyclestudies you will be appointedtodoctoral studentship. Regulations for employment of doctoral students are given in SFS 1993:100. The initial appointment may apply for no longer than one year. An appointment may be renewed for no more than two years at a time. A person may beappointed to a doctoral studentship for a total ofeight years. The total employment period may, however, not exceed the time corresponding to full-time third-cycle study for four years.

Location: Sahlgrenska Academy, Institute of Clinical Sciences, Department ofRadiation Physics.

Extent:100%. First day of employment: as agreed. Salaries for doctoral students are regulated in a local agreement at the University.
