Endovascular Irradiations with beta sources

Abstract

For treatment of restenoses tubes (inner/outer diameter 1 and 2 mm; length 3 or 5 mm) with Y-90 foils, shielded by Ti-layers on all sides have been developed (activity 0.5 - 2 GBq). Quality checks with plastic scintillators have been developed and are correlated to absolute dose measurements performed with TLDs (1x1 mm2; 40 mg/cm2). TLD-handling and calibration for beta-dosimetry are described. Additional measurements for depth-dose and dose distribution around the tubes were done with GAFCHROMIC- films and compared to Monte-Carlo calculations with the MCNP4-code, yielding a half-value depth of 0.8 mm from the tube-surface. Manufacturing and delivery of the sources including leakage tests has been standardized, treatments (irradiation times <5min; irradiation length <30mm) are planned to start in spring `98. (authors) 1 refs., 5 figs.
