Abstract
Radiation dosimeters containing thin KCl:Eu2+ storage phosphors for quantifying and/or verifying the dose of radiation applied during radiation therapy. Methods for measuring the amount of radiation applied from a source of radiation and methods for treating a patient having a cancerous tumor are also provided.
Claims20
A radiation dosimeter for measuring the dose of radiation applied during radiation therapy, the dosimeter comprising a storage phosphor, the storage phosphor having a europium-doped potassium chloride active layer with an effective thickness of less than about 10 μm.
A method for measuring the amount of radiation applied from a source of radiation, the method comprising:
- applying a dose of radiation in the direction of a dosimeter comprising a storage phosphor, the storage phosphor having a europium-doped potassium chloride active layer with an effective thickness of less than about 10 μm;
- optically stimulating the storage phosphor to emit photons;
- detecting emitted photons;
- and
- generating a signal based on the amount of photons detected.
A method for treating a patient having a cancerous tumor, the method comprising;
- applying a targeted dose of radiation to the cancerous tumor;
- and
- verifying that the targeted dose of radiation was applied to the tumor by applying a dose of radiation in the direction of a dosimeter comprising a storage phosphor, the storage phosphor having a europium-doped potassium chloride active layer with an effective thickness of less than about 10 μm.
