ECHOCARDIOGRAM BASIC VIEWS
E chocardiography is a type of diagnostic tool which is used to assess the cardiac function. It is noninvasive painless and a safe technic also Ultrasound: A sound is a form of energy. It is a pressure wave created by mechanical action. Speed of sound is dependent upon the properties of media it is travelling through. It is propagated from waves of compression and rarefaction and requires a tissue to travel. Ultrasound is the most widely used imaging technology around the world. Sound of frequencies higher than 20 kHz can not be perceived by the human ear and is called ultrasound. The human hearing range of the ultrasound wave is approximately 20 kHz.The frequency range of ultrasound which is used for the Echo is in the range of 1.5 MHz to 7.5 MHz. Echocardiography A transducer creates sound waves and receives echoes using the piezoelectric effect. It converts the kinetic or mechanical energy into electrical energy due to the deformation of piezoelectric elements in the probe. Tra
