DESCRIPTION:Speakers: Irina Pashkovich (MEPhI)\nTo determine the depth of 
 the area of radiopharmaceutical accumulation a method based on simultaneou
 s registration of two gamma ray lines of different energies and quantitati
 ve comparison of the intensity of these lines on the surface of the patien
 t's body is developed. The most widely used medical radioisotope technetiu
 m-99m has two gamma-lines - 140 keV and 18 keV\, which allows one to apply
  the proposed method to search for the sentinel lymph nodes and non-palpab
 le malignant tumors in the soft tissues. The result is achieved by the qua
 ntitative analysis of the areas of absorption peaks of technecium-99m. A d
 edicated scintillation detector optimized for low energy gamma rays regist
 ration was designed. This miniature detector consists of a LaBr3:Ce scinti
 llation crystal and a silicon photomultiplier packed together is a sealed 
 aluminum housing with a wall thickness of 0.2 mm. The proposed detector wa
 s used in a set of experimental studies which showed that the lateral coor
 dinate of the Tc-99m source can be determined with an accuracy of ± 4 mm 
 at the depth up to 30 mm a tissue-equivalent phantom.\n\nhttps://indico.pa
