Plan approval for daily plan adaptation

Host: Center of Proton Therapy (CPT) at the Paul Scherrer Institute – PSI, Switzerland.

Planned secondments: MGH (Boston-USA), University of Aarhus (Denmark).

Project description

On-line adaptive proton therapy will require the rapid assessment of new proton treatment plans.

The current method of visualizing plans using planar dose distributions and dose volume histogram (DVH) curves is not the optimal method for rapid dose comparisons.

The primary objectives of this project are (i) to develop rapid and automatic quality assurance tools to assist the plan approval process and (ii) to develop novel methods of detecting and visualizing plan changes.

However, to speed-up the approval process, during the on-line phase, only a selected number of essential quality assurance checks can be performed. Thus, the development of an off-line review module is a fundamental step in an on-line adaptive workflow . The second objective of this study is therefore to define an off-line review module, determine appropriate clinical thresholds triggering a major plan adaptation.

Finally, the validation of the full approval workflow in a clinical environment will be performed.

The project will be mainly carried out at the Center of Proton Therapy  (CPT) at the Paul Scherrer Institute (PSI), supervised by Dr Francesca Albertini. The PhD degree will be awarded by the Swiss Federal institute of Technology Zurich (ETH Zurich), under the supervision of Prof Antony Lomax.

The CPT is the world leader in the development and clinical implementation of pencil beam scanning  and Intensity Modulated Proton therapy , both of which have been pioneered at PSI. The PSI is the largest research institute for natural and engineering sciences within Switzerland. Cutting-edge research in the fields of matter and materials, energy and environment and human health are there performed.  ETH  is one of the universities in Europe which focuses most intensively on research. As such, the PSI in combination with the ETH  provide a unique possibility to combine high level of research with technological developments and transferable skills.
