>Hello everyone,
>I am new to Gate and I want to simulate yttrium radioembolisation treatment. In this treatment a big number of small size microspheres, approximately 1 million spheres of 25 micrometer size are inserted in the human liver and selectively located in the tumor due to the unique blood flow of the liver.
