Understanding 2D Echocardiography
What is 2D Echocardiography?
2D echocardiography utilizes ultrasound technology to visualize the heart in two dimensions. It provides essential information about heart structure, function, and blood flow. The technique involves a phased array transducer that generates ultrasound waves, which reflect off cardiac tissues to create images.
How Does 2D Echocardiography Work?
The standard phased array transducer consists of multiple piezoelectric crystals. When activated in a specific sequence, these crystals emit ultrasound waves that create a sector-shaped image. The process involves rapid activation, allowing for continuous updates and high frame rates necessary for dynamic imaging.
