DRIVER DEVICE FOR MAGNETIC RESONANCE ELASTOGRAPHY

摘要

A drive unit for the magnetic resonance elasticity technique is provided to control the vibration delivered to a human body by controlling the fluid supply volume. An MRE drive unit comprises a fluid emission part(16), a fluid supplier(14), a main housing(12), a driving housing(18), a pressurizing piston(26), a pressurizing cylinder(24) and a presser portion(22). A main housing has a first and send fans(34a, 34b) rotating with the fluid. A driving housing has a first, and second eccentric gears(38a, 38b) equipped in the lower part of the main housing and respectively connected with the first and send fans. The pressurizing piston and the pressurizing cylinder are equipped on the top of the main housing. The presser portion pressurizes to the lower part of the main housing by including a pressurized fluid feed port(28) supplying the separate fluid to the pressurizing cylinder. An assistant plate(30) performs as an assistance, is equipped on the top of the pressurizing cylinder when adhering the MRE drive unit to a human body.
