System and method for intravascular ionizing tandem radiation therapy |
摘要 |
A system for intravascular ionizing radiation therapy including a radiation device and a guide wire having radiopaque markers to facilitate precise repositioning of the radiation source along the length of the treatment site. The radiopaque markers are separated by a distance L, which corresponds to the distance between the 50% dose points in the dose fall-off regions. This produces partial dose overlap when the radioactive source is positioned in tandem adjacent each radiopaque marker. Preferably, only the dose fall-off regions overlap thereby providing more uniform and complete radiation exposure along the length of the treatment site.
