What is frame rate in echocardiography?

In an ordinary cardiac imaging, by considering 128 lines per frame, 20 cm depth and 1500 m/s for the speed of sound, the maximum frame rate is around 30 (frames/sec). But for fast moving structures, such as heart valves, a frame rate up to 80 (frames/sec) may be required.

What do abnormal echocardiogram look like?

Echo Results and The Functions of The Heart For example, the test can show if the heart is enlarged or has thickened walls. Walls thicker than 1.5cm are considered abnormal. They may indicate high blood pressure and weak or damaged valves.

Does an echocardiogram have images?

An echocardiogram can help your doctor diagnose heart conditions. An echocardiogram uses sound waves to produce images of your heart. This common test allows your doctor to see your heart beating and pumping blood. Your doctor can use the images from an echocardiogram to identify heart disease.

How is frame rate calculated?

To calculate frames per second, you just take the number of rendered frames and divide it by the seconds passed.

Why is frame rate important in sonography?

High frame rates enable us to see rapidly moving structures (such as heart valves) without motion artifacts, and also perform velocity and deformation analysis (i.e. tissue Doppler).

What does red mean on an echocardiogram?

Traditionally, flow towards the transducer is red, flow away from the transducer is blue, and higher velocities are shown in lighter shades. To aid observation of turbulent flow there is a threshold velocity, above which the color changes (in some systems to green).

How can I tell the frame rate of a video?

To find out video resolution and frame rate of a video file, you can simply view its properties in modern Windows or any other OS. In Windows 7, the information is found out from the Properties > Details (tab) of a video. Video information like frame width and frame height is present there.

How do you calculate maximum frame rate?

For example, for image size (512×512) the maximum frame rate = 1733 and shutter = 2320 microsecond and for the full resolution (1280×1024) the maximum frame rate is = 430 and shutter time is 2319.
