Photochemotherapy dosimeter

摘要

A photochemotherapy dosimeter for monitoring cumulative photochemotherapy radiation dosage. The photochemotherapy dosimeter includes an optical fiber having a chemical cell attached at one end thereof. The chemical cell contains a photobleachable chemical which can be in a solution or incorporated into a matrix material. Changes in the absorption of the photobleachable chemical are used to monitor the cumulative photochemotherapy radiation dosage. In use, the chemical cell of the photochemotherapy dosimeter is positioned near an abnormal tissue which is subjected to photochemotherapy treatment.
