HYDRAULICALLY-POWERED SYSTEM AND METHOD FOR ACHIEVING MAGNETIC RESONANCE ELASTOGRAPHY |
摘要 |
A system for inducing tissue vibration for magnetic resonance elastography is described. The system includes a passive actuator component, a first hose, a second hose, and a driving component. The passive actuator component is positionable proximate to a target tissue and includes a linearly movable piston assembly enclosed in a housing. The driving component includes a fluid pumping system and is configured to alternatingly pump a fluid through the first hose and through the second hose. When fluid is pumped through the first hose, the piston assembly moves in a first linear direction and, when fluid is pumped through the second hose, the piston assembly moves in the opposite direction. The alternating linear movement of the piston assembly induces vibration in the target tissue. |
