An emerging technology that uses the body's own seismic noise allows more effective imaging deep inside body to assist in tumour scientists say. Elastography sometimes referred as seismology of the human body measures the elasticity of biological tissue to diagnose cancer or liver and thyroid disease more accurately and at the earliest stages. In passive elastography the elasticity of tissue is measured using the body's own propagation of shear waves which enables more effective imaging deeper inside the body in an even more non-invasive way than the traditional elastography. Passive elastography is foreseen as a viable technique for cancer detection
