Electron beam therapy planning and custom electron bolus design were identified as areas in which improvements in equipment and techniques could lead to significant improvements in treatment delivery and patient outcomes.

A novel optical calorimetry approach is proposed for the dosimetry of therapeutic radiation, based on the optical technique of Digital Holographic Interferometry (DHI). This detector determines the radiation absorbed dose to water by measurement of the refractive index variations arising from radiation induced temperature increases. The output consists of a time series of high resolution, two dimensional images of the spatial distribution of the projected dose map across the water sample. This absorbed dose to water is measured directly, independently of radiation type, dose rate and energy, a

ABSTRACT Intensity modulated beams use complicated computerized treatment planning systems; this makes a manual verification of the number of monitor units difficult to perform. Consequently, before treatment, patient-specific quality assurance must be done in order to ensure that the delivery agrees with the plan; this process involves a measurement of 2D dose distribution in a phantom. In this thesis, first, a photostimulable phosphor luminescence device (also referred to as computed radiography or CR) was evaluated for dosimetric purposes.

When measuring dose profiles, the ionization chamber measurements were first corrected for response variation in off-axis direction, and then deconvolved to eliminate the blur due to the poor resolution of the chamber.

Dosimetry is the methodology of determining the amount of radiation energy imparted in matter and volume. Although several techniques and devices are available for use in both laboratory and clinical settings, most rely on certain conditions, assumptions and approximations to convert the energy into radiation dose. The many uncertainties from current techniques are introduced due to the material differences between the sensitive detector volume and the phantom material, typically water.

This thesis presents interdisciplinary, collaborative research in the field of synchrotron microbeam radiation therapy (MRT). Synchrotron MRT is an experimental radiotherapy technique under consideration for clinical use, following demonstration of efficacy in tumour-bearing rodent models with remarkable sparing of normal tissue. A high flux, X-ray beam from a synchrotron is segmented into micro-planar arrays of narrow beams, typically 25 μm wide and with peak-to-peak separations of 200 μm. The radiobiological effect of MRT and the underlying cellular mechanisms are poorly understood. The

Streszczenie:
Radiation therapy is an established modality in the treatment of tumours. With treatments ever evolving and increasing in terms of their complexities, the need arises to ensure the best quality treatment is delivered; the survival of the patient relies upon it. A modern treatment such as Intensity Modulated Radiation Therapy employs steep dose gradients varying dynamically to deliver complex dose profiles, whilst the experimental Microbeam Radiation Therapy (MRT) involves the delivery of an array of intense beams tens-of-microns wide separated by several hundred microns. In both cases, convent
