Ultrasound imaging employs acoustic waves to generate images of internal body structures.

Ultrasound imaging typically utilizes frequencies in the range of 1-10 MHz for optimal imaging depth and resolution.

Ultrasound waves are generated through the piezoelectric effect, where electrical energy is converted into mechanical vibrations.

A transducer in ultrasound imaging serves multiple purposes, including generating ultrasound waves, receiving reflected waves, and converting electrical signals to ultrasound waves.

Ultrasound scanning refers to the real-time acquisition of ultrasound images, allowing for dynamic visualization of internal structures.

Ultrasound imaging is not commonly used for neurological imaging due to the limited penetration of ultrasound waves through the skull.

Beamforming is the process of combining multiple ultrasound signals to create a focused image.

Ultrasound imaging offers several advantages, including its non-invasive nature, real-time imaging capability, and relatively low cost.

Acoustic impedance determines the ability of ultrasound waves to penetrate different tissues, affecting the quality of the resulting images.

The quality of ultrasound images can be influenced by various factors, including the frequency of ultrasound waves, the type of transducer used, and the patient's body habitus.

Ultrasound imaging can be used to guide various medical procedures, including biopsies, surgeries, and therapies.

Ultrasound imaging has certain limitations, including limited penetration depth, inability to image certain tissues, and susceptibility to artifacts.

Doppler ultrasound, color Doppler ultrasound, and power Doppler ultrasound are all techniques used to assess blood flow using ultrasound imaging.

Elastography, strain elastography, and shear wave elastography are all techniques used to assess tissue elasticity using ultrasound imaging.

Ultrasound imaging is generally considered safe, with no known significant safety concerns.
