symbol on camera to sheet<br /> * Checked camera in focus with ruler in front/back and middle of two blocks.<br /> * Pelicase on couch<br /> * Scintillator blocks aligned to laser cross hairs<br /> * 785 mm source to surface distance suitable for output factor/PDD/profile measurements.<br /> * Room lights out and pelicase window closed by 1mm plastic.<br /> * Check optical axis aligned with top surface using crosshair in the image analysis.<br /> * Used shims to level top surface of plastic blocks and scintillator sheet<br /> <br /> === Camera settings ===<br /> * Focal length 20mm <br /> * lens focus distance – 0.5 (500mm)<br /> * 53cm focal plane (phi on camera ) to sheet<br /> * f-number 5.6<br /> <br /> == Data taking ==<br /> === Plan ===<br /> * Position camera by placing aligning crosshair on image with top surface of block<br /> * Take photos of blue sheet with blocks starting from 60mm collimator size to 5mm.<br /> * Remove blue sheet – repeat measurements<br /> * Position camera by placing aligning crosshair on image with top surface of block<br /> * Use new set of blocks and blue sheet - repeat measurements<br /> &lt;!-- ------------------------------------table1------------------------------------------ --&gt;<br /> <br /> {|class=&quot;wikitable&quot;

This X-ray beam is continuously modulated and shaped by adjusting both its intensity and the shape of the beam. This results in a highly conformal dose distribution that changes continuously over time, making dosimetry during treatment significantly more complex than when treatment is delivered with static fields. Emerging methods such as small-field and high dose-rate irradiation are even more challenging with current dosimetry methods. Standard detectors such as ion chambers are unsuitable for measuring complex small fields due to volume averaging and loss of charge particle equilibrium. These problems can be solved with the proposed detector system consisting of an irradiated scintillator sheet that is photographed, from which the dose is reconstructed. This provides a cheap, fast, and high-resolution solution. But scintillation images come with a variety of visual artefacts that need correcting.<br /> <br /> == [[/Experimental Runs|Experimental Runs]] ==<br /> <br /> Details of each of the experimental data taking runs carried out at Birmingham.</div> JeremyOcampo https://www.hep.ucl.ac.uk/pbt/pbtWiki/index.php?title=Radiotherapy/Experimental_Runs/2020-02-04&diff=4624 Radiotherapy/Experimental Runs/2020-02-04 2022-08-24T15:52:33Z <p>JeremyOcampo: /* Data Taking */</p> <hr /> <div>Second experimental measurements with Cyberknife at Birmingham.<br /> Green scintillator thin sheet measurements only.<br /> <br /> == Setup ==<br /> <br /> === Schematic ===<br /> &lt;div class=&quot;image600px&quot;
