Abstract

Pasywny sterownik do wywierania naprężenia na badanym obiekcie podczas elastografii rezonansu magnetycznego (MRI), zawierający elastyczną rurkę (3) o przekroju okrągłym, złącze (1) oraz elastyczny element wibrujący (5), wypełniony gazem, a jeden koniec rurki (3) jest połączony ze złączem (1) skonfigurowanym do łączenia się ze sterownikiem akustycznym generującym fale akustyczne gazu, a drugi koniec rurki (3) jest połączony przepływowo ze środkową częścią elementu wibrującego (5), charakteryzuje się tym, że element wibrujący (5) w środkowej części jest rozgałęziony symetrycznie i tworzy dwa elementy drgające, których końce są zaślepione a przekrój poprzeczny jest zasadniczo eliptyczny, wewnątrz których znajduje się filtr gazu wykonany z materiału zapewniającego swobodny przepływ gazu wewnątrz elementów drgających oraz element mocujący (8) pasywny sterownik.A passive driver for exerting stress on a test object during magnetic resonance imaging (MRI) elastography, comprising a flexible tube (3) of circular cross-section, a connector (1) and a flexible vibrating element (5) filled with a gas, one end of the tube (3) being connected to the connector (1) configured to connect to an acoustic driver generating acoustic waves of the gas, and the other end of the tube (3) being in fluid communication with a central part of the vibrating element (5), characterized in that the vibrating element (5) in its central part is symmetrically branched and forms two vibrating elements, the ends of which are plugged and the cross-section of which is substantially elliptical, inside which there is a gas filter made of a material ensuring a free flow of gas inside the vibrating elements, and an element (8) securing the passive driver.
