Tissue Doppler echocardiography Tissue Doppler echocardiography Tissue Doppler echocardiography (TDE) is a medical ultrasound technology, specifically a form of echocardiography that measures the velocity of the heart muscle (myocardium) through the phases of one or more heartbeats by the Doppler effect (frequency shift) of the reflected ultrasound. The technique is the same as for flow Doppler echocardiography measuring flow velocities. Tissue signals, however, have higher amplitude and lower velocities, and the signals are extracted by using different filter and gain settings. The terms tissue Doppler imaging (TDI) and tissue velocity imaging (TVI) are usually synonymous with TDE because echocardiography is the main use
101 Things Removed from the Human Body 101 Things Removed from the Human Body 101 Things Removed from the Human Body and 101 More Things Removed from the Human Body is a British "shockumentary" series directed by Eric Schotz, which is narrated by Mitch Lewis. The program features tales of foreign objects that have been removed from human bodies in the form of a countdown from 101 to 1. Items included are javelins, a boat anchor, a bicycle pump, a bag of nails, an ice pick, and a human body. The documentary series was first broadcast on Sky One in October 2003.
