CURIETHERAPY Photo essay from hospital. Prostate brachytherapy at the Hospital Saint Louis in Paris. This technique enables a high dose of radiation to be delivered directly to the tumor to be treated while avoiding exposing healthy tissues. The main advantage of brachytherapy resides in this low toxicity for organs in the proximity of the tumor. Shown here, brachytherapy by implanting seeds of 125 radioiodine, used for superficial prostate cancers. In vivo dosimetry: the physicist in the forefront calculates and views the dose delivered to the prostate in real time during the implant procedure. She can indicate where to place any additional seeds if necessary.
