About Ultrasound (04:43)


Ultrasound is sound waves with frequencies above the upper audible limit of human hearing and is used for diagnostic detection or prenatal development. Learn the technologies benefits and drawbacks. Pioneers in the field include Pierre Curie, Dr. Karl Theodore Dussik, and Ian Donald.

Instrumentation (02:26)

Use high or low frequency sound waves depending on imaging parameters. Measuring the time it takes for the echo to reach the probe calculates the depth of the tissue interface. Learn how to rotate the transducer beam to achieve optimal results.

Doppler Ultrasonography (03:39)

This technique measures blood flow and muscle movement using colors. Modern ultrasounds employ a phased array technique to allow the machine to change direction and depth of focus. A water based gel is placed between the probe and the patient's skin to reduce static and act as a coupling agent.

Types of Ultrasound (06:15)

Endovaginal, endorectal, and transesophageal transducers can improve diagnostics. Learn the different uses for amplitude modulation, brightness modulation, motion, continuous wave, and Doppler mode. Pulsed Doppler provides distance information.

Spectral Doppler (02:11)

Learn spectral, duplex, color, and power Doppler mode uses. Velocity is displayed on the vertical axis; flow toward the transducer appears above the x-axis.

Contrast Agents (03:06)

Use these liquids to improve images from smaller vessels. Artifacts are features of an ultrasound image that does not correspond to anatomical structures. Endoprobes can bypass any tissues or bones that are too solid or thin. Learn what different readings mean on an ultrasound machine.

Operations (02:18)

Learn different types of interventional ultrasound. Ultrasound guided diagnostic procedures only when less invasive methods are not available. Percutaneous abscess draining is preferred for stomach abscesses.

Setting Up the Ultrasound (02:12)

Different arrays are used for different frequencies. Echocardiography requires electronic sector scanners and integrated Doppler techniques. Learn different settings and arrays needed for different anatomical structures.

Obstetric Concerns (02:55)

Review commons settings and proper protocol during the first, second, and third trimester. Fetal biometry can determine longitudinal growth.

Interpretation: Organs (02:28)

Use b-scan to determine organ abnormalities and fluid collections. Contour evaluation is limited in Ultrasound. Single echoes are weak, average, or strong; learn how to determine whether an organ is echo-poor or echo rich.

Interpretation: Doppler Ultrasound (02:58)

Consider angle dependency and aliasing when interpreting Doppler images. Learn when to use power, color, and spectral Doppler techniques. Because ultrasound is portable, inexpensive, and easy to use, it is a preferred diagnostic tool.

This program includes a brief history of the medical use of Ultrasound and an explanation of sound wave transmission, reception and image formation. This video covers multiple ultrasound modulation techniques including Doppler, and the use of contrast agents. The Operations segment explains possible adverse effects along with an overview of interventional ultrasound, equipment adjustments and the use of ultrasound in obstetrics.  The Interpretation segment of the program covers both B-scan and Doppler ultrasound.
