Transit Dosimetry for Patient Treatment Verification with an Electronic Portal Imaging Device
… intensity modulated radiation therapy (IMRT) treatment planning must be verified before they are delivered to the patient. There is a compelling argument for additional verification throughout the course of treatment due to the possibility of data corruption, unintentional modification of the …

Determination of Thermal Dose Model Parameters Using Magnetic Resonance Imaging
… damage by functioning as a surrogate for post-treatment verification imaging. This aids in maximizing the safety and efficacy of treatment by facilitating adaptive control of the damaged volume during therapy. The underlying thermal dose parameters are derived from laboratory experiments that …

The dual development of an optical tomographic scanner and three dimensional gel dosimeter for complex radiotherapy verification
The state-of-the-art radiotherapy delivery treatments available today require that the intended dose distributions delivered are verified by volumetric gel dosimetry. The development of tissue equivalent gel dosimeters that provide an integrated assessment of the dynamic treatments, are primarily …

Portal Imaging Using a CSI (TL) Scintillator Coupled to a Cooled CCD Camera
<p>The purpose of this research was to design a high performance digital portal imaging <br />system, using a transparent x-ray scintillator coupled to a cooled CCD camera. Theoretical <br />analysis using Monte Carlo simulation was performed to calculate the QDE, SNR and DQE of <br />the system. A …
