Abstract

The invention belongs to the technical field of magnetic resonance imaging, and particularly relates to a magnetic resonance elasticity imaging method and system. The magnetic resonance elasticity imaging method comprises the following steps: a, sending a trigger pulse signal through a magnetic resonance imaging device; b, detecting the frequency of the trigger pulse signal through an external excitation device, and setting the vibration frequency of the external excitation device according to the frequency of the trigger pulse signal, wherein the set vibration frequency of the external excitation device and the vibration frequency of the magnetic resonance imaging device are synchronous; c, outputting a signal to a tested object through the mode that the magnetic resonance imaging device triggers the external excitation device, and obtaining elasticity images of the tested object. Due to the fact that the magnetic resonance imaging device sends the trigger pulse signal to the external excitation device in advance, the vibration frequency of the magnetic resonance imaging device and the vibration frequency of the external excitation device are synchronous automatically through the trigger pulse signal, manual operation for regulating the vibration frequency is saved, collection time is shortened, and collection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of magnetic resonance imaging, and in particular relates to a magnetic resonance elastography method and system. Background technique [0002] Elasticity (or hardness) is an important mechanical parameter in the physical properties of biological tissues such as the human body. The elastic modulus or hardness of biological tissues depends on its molecular composition and corresponding microstructure, and is closely related to its biological characteristics. Elasticity changes in biological tissues are often closely related to pathological phenomena. There is usually a difference in elastic modulus or hardness between diseased tissue and normal tissue. This difference provides important reference information for the diagnosis of clinical diseases. [0003] The elastography technique for detecting the elastic modulus of biological tissue is a diagnostic imaging technique emerging in recent years. Its basic prin...
