Action
The firm, Accuray, sent an "URGENT DEVICE CORRECTION" letter dated January 18, 2010, to all customers. The letter described the product, problem and action to be taken by the customers. The customers were instructed to load the plan and recalculate the dose to reflect the current state of beam, compare the reloaded plan and the recalculated plan to verify maximum dose and prescription values, and re-prescribe and save to overwrite to existing plan if necessary. The firm is developing a patch/software update to address the issue and a Accuray Customer Support person will contact the customer regarding further resolutions. If you have any questions or concerns regarding this issue, contact Accuray Customer Support at +1-877-668-8667(USA) or +1-408-716-4700 (non USA) or email: customersupport@accuray.com.
