Изобретение относитс к медицинской технике, а именно к устройствам дл радиризотопной диагностики.The invention relates to medical technology, in particular to devices for radiotrophic diagnostics.
Известно устройство дл компенсации временных задержек скенера, содержащее электромагнит с двум независимыми обмотками и сердечником, жестко св занным со штоком, несущим блок регистрации и расположенным внутри полой штанги, электроизолированное замыкающее кольцо, электромагнитный тормоз с двум электроконтактами и р д пар электроконтактов по числу скоростей сканировани 1.A device for compensating for time delays of a scanner is known, which contains an electromagnet with two independent windings and a core rigidly connected with a rod carrying a recording unit and located inside a hollow rod, an electrically insulated closing ring, an electromagnetic brake with two electrical contacts and a number of pairs of electrical contacts according to the number of scanning speeds one.
Однако данное устройство обеспечивает компенсацию временных задержек только в зависимости от скорости сканирова , ни , в то врем как необходима величина выбега зависит также и от величины ионизирующего излучени . Учет лищь одного фактора снижает точность получаемой при сканировании информации.However, this device provides compensation for time delays only depending on the scan rate, nor, while the amount of coasting required is also dependent on the amount of ionizing radiation. Accounting for only one factor reduces the accuracy of the information obtained during scanning.
Известно также устройство дл компенсации временных задержек скенера, содержащее электромагнит с двум независимыми обмотками и сердечником, жестко св занным со штоком, несущим блок регистрации и расположенным внутри полой штанги , несущий блок детектировани , неподвижно насаженное на шток электроизолированное кольцо и электромагнитный тормоз с двум электроконтактами 2.It is also known a device for compensating the time delays of a scanner, comprising an electromagnet with two independent windings and a core rigidly connected to a rod carrying a recording unit and located inside a hollow rod, carrying a detection unit fixedly mounted on a stem electrically insulated ring and an electromagnetic brake with two electrical contacts 2 .
Недостатками известного устройства вл ютс дополнительные расчеты рассто ни , необходимого дл компенсации временных задержек, которые производ тс вручную перемещением колец на рассчитанное рассто ние, возможность работы при несоответствии выбранной скорости сканировани установленной величине выбега дл компенсации временных задержек. Таким образом, информаци , получаема при сканировании , вл етс неточной.The disadvantages of the known device are additional calculations of the distance required to compensate for the time delays, which are made manually by moving the rings by the calculated distance, the ability to work when the selected scanning speed does not match the specified overrun to compensate for the time delays. Thus, the information obtained by scanning is inaccurate.
Цель изобретени - повышение точнос (5 ти получаемой при сканировании информации .The purpose of the invention is to improve the accuracy (5 information obtained when scanning.
