As radiotherapy using ultra-high dose rates has gained new interest, the dosimetric challenges arising at these conditions needs to be addressed. Ionization chambers suffer from a large decrease in ion collection efficiency due to ion recombination,

Background: Radiotherapy is based on the premise of accurate dose delivery to target volumes within a patient, while minimizing dose to surrounding tissues. Recent developments in the treatment of breast cancer have focused on “gating” the delive

Deep brain stimulation, DBS, is an accepted technique for the treatment of Parkinson's disease. DBS affects the electrical functions of neurons, but exactly how it alters those functions is not clearly explained. An electrical model is determined to

A controlled pulsed electrical field applied to a living tissue is believed to cause a structural reorganisation in the lipid bilayer of the cell membranes. This electropermeabilisation or electroporation process is used for opening up the cell membr

The most fundamental characterisation of the electron beam of a linear accelerator is the distribution of incident electrons differential in energy, angle and position. The simplest way to determine an electron spectrum would be to use a scintillatio

For the Philips SL75/5, we have noticed that the performance of the beam (e.g. the hump) varies with the settings of the magnetron frequency and the gantry angle. This study investigated these changes and the optimum magnetron frequency setting was d

High frequency electrical stimulation by means of electrodes implanted into the brain has become an accepted technique for treatment of Parkinson's disease. The electrical field distribution normally inserted into the sub thalamic nucleus minimise ab
