Dosimetry for an Sr90/Y90 source train used for intravascular radiation of a hemodialysis graft.

Objective: Vascular access for hemodialysis is often achieved with an arterial-venous graft (AVG). Brachytherapy is being explored for prevention of stenosis within these grafts. The objective was to develop treatment planning (TP) capability for dialysis implants.

Monte Carlo dose characterization of a new 90Sr/90Y source with balloon for intravascular brachytherapy.

Beta emitting source wires or seeds have been adopted in clinical practice of intravascular brachytherapy for coronary vessels. Due to the limitation of penetration depth, this type of source is normally not applicable to treat vessels with large diameter, e.g.
