摘要：
The utility model refers to special diagnostic tools for reusable gamma cameras intended for early diagnosis of tumors, metastatic lesions and other diseases by visualizing the distribution of radioactive drugs introduced into the human body for diagnostic purposes.The useful model consists of a housing, a measuring unit, a high voltage source, a battery pack, a photoelectron multiplier signal amplifier, a processor with indicators, a charger, refers to scintillation detection devices for recording ionizing radiation. The device is enclosed in a plastic housing. The measuring unit consists of a collimator, a scintillator, a photoelectric multiplier - a photomultiplier, a voltage divider. A collimator for separating the flow of radio-frequency particles from a given direction and arriving at a certain angle has dimensions: diameter 19 mm, length 39 mm, made of lead by casting, side walls 5 mm thick, in the focusing part 25 mm, designed to A particle flux of 3 mm in diameter and a resolution angle of 18 ° entered the scintillator.3, The refractive index is 1.9, the spectral emission maximum is 370 nm, the decay time is 30 ns. The photoelectric multiplier (PMT) is an electrovacuum device consisting of a cathode, an anode and 10 dynodes enclosed in a hermetically sealed glass flask with dimensions: diameter 15 mm, length 70 mm, intended for converting light pulses into electrical pulses. The voltage divider is a set of 10 resistors, the resistance of resistors with resistance not exceeding 0.3 MΩ, connected in series, located on a printed board with a diameter of 18 mm, designed to create certain specified voltages on the photomultiplier dynodes. There is a high voltage source, a battery pack, a photomultiplier signal amplifier, a processor with indicators, a charger. Technical, software,Using a useful model will reveal functional changes in the work of internal organs, tumors, lymph nodes, metastases during surgical treatment.Полезная модель относится к специальным диа
