## Indications for use
EDOSE is indicated to be used as an independent quality assurance (QA) tool for the treatment planning system, to verify that the treatment plan is in fact successfully delivered to the patient. EDOSE is used by oncologist, radiotherapy physicist and/or radiotherapy dosimetrist to check the accuracy of the delivery by high energy linear accelerator that are planned to be applied or have been applied to a patient. By using the specific measuring device, the product can output the dose distribution of the patient or phantom based on treatment field image data and theoretical calculation. The product can calculate and check the dose distribution to be or has been delivered. In addition, the product may be used to display the dose distribution on other fused image sets which could provide additional clinical information to the radiation oncologist regarding the treatment.
