INTERVENTIONAL INJURY SIZING TOOL FOR RADIATION THERAPY

摘要

An interventional measuring tool for assisting with the accurate and precise determination of the effective radiation source length that will deliver the prescribed radiation or brachytherapy dosage to a targeted site within a patient. The interventional measuring or sizing tool (10) includes an elongated wire (11) having a proximal section (12), a distal section (16), and an intermediate section (14) therebetween, and two or more radiopaque markers (18) affixed to the distal section (16) of said elongated wire (11), the radiopaque markers (18) spaced at predetermined distances that indicate to the user the effective lenth of the radiation source that will provide for effective radiation dosing of the targeted tissue being treated.
