Introduction. The Tomotherapy HI-ART II helical tomotherapy system (Tomotherapy, Inc., Madison, WI, USA) achieves highly conformal dose distributions using a helical-CT like IMRT delivery paradigm.[1,2] Daily image-guidance is provided by an integrated megavoltage CT system used to reduce set-up errors allowing more accurate targeting of dose to the intended volume.

• Complex prescriptions or “dose painting”. • Higher dose/fraction can be delivered to the tumor and still have low dose and dose/fraction to critical tissues. • Conformal avoidance. • More accurate setup of the patient. • Better verification that delivery is correct. • Have a basis to repair dose distributions. • …

Accuracy in TomoTherapy treatment delivery can be susceptible to LOT uncertainty. Using MCLogQA for QA verification not only validates the treatment delivery, but also provides information on LOT variation and comprehensive dose distribution. This information can help decision making when large plan-delivery deviation occurs.

A clinical case of delivery dose deviations on a TomoTherapy treatment was discovered during a patient specific treatment quality assurance (QA) verification. An in-house developed QA system, MCLogQA, for TomoTherapy has been implemented in our clinic for patient specific treatment QA.
