Abstract
Radiation output directed toward at least one field of an object, such as a patient, is sensed, for example, during a session of radiation therapy. The accumulated dose delivered to the field is displayed and updated throughout the delivery of radiation. A prescribed dose profile may also be displayed simultaneously so the user can compare the accumulated dose with the prescribed dose profile over the irradiated field. Dose profiles--both prescribed and accumulated--are preferably stored in a memory unit. Profiles for several different fields at several different times may be stored and used to direct and monitor the course of radiation treatment.
