Figure 5
An alignment of a rodent to the synchrotron beam is shown using SyncMRT. The rodent, immobilized on the DynamicMRT system, is imaged using the radiographic X-ray tube at 0° and 90°. Three bony anatomical landmarks are selected in each image, allowing SyncMRT to calculate a movement to bring the target volume into alignment with the synchrotron beam. The red square denotes the current field position; the yellow (dotted) square denotes the desired field position (the target volume). The field overlays are a visual guide, and are only correct for the radiograph that matches the treatment angle. The lines and patches of dead or damaged pixels present in the images are a result of radiation damage to the imaging detector. |
