Intravascular radiation therapy for prevention of restenosis is a new emerging technology, which is tested, nowadays, in clinical trials. Several methods of radiation and a variety of isotopes have been tested in different animal models in order to prove the concept and to find a friendly user system for this application. One of the possible intravascular irradiation techniques is to use catheter-based system. The 32P-radiation source made in this study was 0.5mm in diameter and 27mm in length. We first encapsulated 32P by a plastic tube and then encapsulated in a specially manufactured NiTi wire with a diameter of 0.65mm and a length of 2.5m. This solid and flexible wire with the 32P source located in the tip of the wire can be easily inserted in to a coronary vessel. We tested the quality assurance program according to classification of quality assurance of radiation sources, Atomic Energy Regulatory Board (A.E.R.B) at this case.
