Radiation Treatment Accuracy Starts Here

Precision in CT simulation affects subsequent radiation treatments. The goal is to destroy cancer cells without doing harm to nearby healthy tissue.
With accuracy measured in millimeters, the quality of each tool the radiation therapist uses for set-ups and treatment planning makes a difference.
Streak artifact from high-attenuation materials, such as metallic markers can distort the true density of normal tissue and affect radiation dosage calculation. As a result the dosimetrist spends more time trying to factor out the distortion and match the affected tissue with the houndsfield units of nearby tissue unaffected by the distortion.
