Brief Summary:
We propose to determine the response of a newly developed laser heated vycor glass fiberoptic radiation dosimetry system to ionizing radiation in a clinical radiotherapy environment Present systems measure only total dose or have limitations such as instability non-linearity excessive size or a decoupled measurement system making them unsuitable in a variety of clinical applications This fiberoptic coupled dosimetry system is a new and innovative technology application which allows on-line measurement of instantaneous dose rate and total dose never before achievable It offers a clear advantage in patient treatment delivery allowing on-line corrections essential to a new generation of radiotherapy treatment machines with development of beam intensity modulation as an adjunct to 3D conformal therapy It also has the advantage of submillimeter size and is minimally invasive making it ideal for brachytherapy
This system has the potential for stable accurate reproducible clinically feasible measurements of total dose and dose rate The output of this system will be measured under various clinical conditions encountered in a clinical setting and compared against existing thermolumeniscent and diode dosimetry standards Initial measurements will use a tissue equivalent phantom for depth dose and accuracy measurements Additional studies will include dosimetric measurements of routine clinical treatment setups on patients receiving therapeutic irradiation
This system has the potential for stable accurate reproducible clinically feasible measurements of total dose and dose rate The output of this system will be measured under various clinical conditions encountered in a clinical setting and compared against existing thermolumeniscent and diode dosimetry standards Initial measurements will use a tissue equivalent phantom for depth dose and accuracy measurements Additional studies will include dosimetric measurements of routine clinical treatment setups on patients receiving therapeutic irradiation
