Abstract (sommario):
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. The electron pencil beam algorithms used in conventional Treatment Planning Systems do not accurately model the dose distribution in irregularly shaped objects, near oblique surfaces or in inhomogeneous media. For this reason, at Christchurch Oncology Centre the TPS is not relied on for planning electron beam treatments. This project is an initial study of ways to imp

Abstract (sommario):
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 (sommario):
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.

Several dosimetric parameters were measured for three very small radiation fields (1.5, 3, and 5 mm diameter at the machine isocenter) with a small ionization chamber and a new type of radiochromic film. The experiments were carried out on a Clinac-18 linac and the fields were shaped by specially manufactured collimators. 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.
