摘要:
A system and method for calibrating and positioning a radiation therapy treatment table with a high degree of precision and accuracy. The treatment table includes radiographic indexing markers embedded or inlaid therein. The radiographic indexing markers can include a density different from density of the table material, or a radio-frequency or magnetic contrasting matter, something that the imaging system and detector of the radiation therapy system can detect, so that when scanned, with or without a patient or phantom on the table, the precise location of the patient treatment table in the x, y and z planes is known. This is important so that the table may be reconstructed, alone or with a phantom on it, by the radiation therapy system software, providing a very good indication of where the table top is prior to treatment.
