The terms tissue Doppler imaging (TDI) and tissue velocity imaging (TVI) are usually synonymous with TDE because echocardiography is the main use of tissue Doppler. Like Doppler flow, tissue Doppler can be acquired both by spectral analysis ( spectral density estimation ) as pulsed Doppler [ 1 ] and by the autocorrelation technique as colour ...
[15] [16] [17] Tissue Doppler technology, the alternative method for strain rate imaging to speckle tracking technology, requires achieving sufficient parallel orientation between the direction of motion and the ultrasound beam. Its use has remained limited due to angle dependency, substantial intraobserver and interobserver variability and ...
[9] [10] In this case, the echocardiography transducer (or probe) is placed on the chest wall (or thorax) of the subject, and images are taken through the chest wall. This is a non-invasive, highly accurate, and quick assessment of the overall function of the heart. TTE utilizes several "windows" to image the heart from different perspectives.

A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound.In this case, the probe (or ultrasonic transducer) is placed on the chest or abdomen of the subject to get various views of the heart.
Video footage of the rockslide shows the rocks tumbling down along with parts of mountain onto the road in a cloud of dust. The video was recorded by Sierra Wright, who told Storyful she made the ...
At least five drone shows have been canceled, or have paused the use of the systems, after several drones struck a crowd at a holiday show in Orlando on December 21.. Universal Orlando, Orlando ...
The term "schlieren imaging" is commonly used as a synonym for schlieren photography, though this article particularly treats visualization of the pressure field produced by ultrasonic transducers, generally in water or tissue-mimicking media. The method provides a two-dimensional (2D) projection image of the acoustic beam in real-time ("live ...
