Used to send and receive the ultrasound waves.

Medium that helps in the transmission of ultrasound waves from the transducer to the body.

Contains knobs, switches, and controls to adjust the ultrasound machine's settings.

Displays the real-time images generated by the ultrasound machine.

Controls the electrical pulses that the transducer sends into the body.

Adjusts the brightness of the image at different depths to compensate for attenuation.

The ratio between the largest and smallest signal strengths that the ultrasound machine can handle.

The change in frequency or wavelength of the ultrasound waves as they reflect off moving objects, like blood.

Displays the ultrasound information as dots of varying brightness, forming a 2D image.

Displays movement of structures over time, often used to measure cardiac structures.

Used to visualize blood flow velocity over time in a graphical representation.

Reduction in the intensity of the ultrasound beam as it travels through tissue.

The ability of a tissue to produce echoes and reflect the ultrasound waves back to the transducer.

Dependency of the echo intensity on the angle of the ultrasound beam in relation to the structure being imaged.

Uses the non-linear propagation of ultrasound through tissue to enhance image quality.

A property of tissue that affects how much ultrasound beam is reflected at boundaries.

The range of brightness in the B-mode image representing the different intensities of echoes received.

The ability of the ultrasound machine to generate immediate images during scanning.

Refers to a structure that does not produce echoes and appears black on the ultrasound image.

Refers to structures that produce fewer echoes and appear darker than surrounding tissues.

Refers to structures that produce more echoes and appear brighter than surrounding tissues.

Describes structures that produce a similar amount of echoes to the surrounding tissue, thus appearing similar in echogenicity.

Uses pulses of ultrasound to measure the velocity of moving structures, such as blood, at a specific location.

Uses continuous ultrasound beams to measure the velocity of moving structures, like blood, throughout the beam path.

Misrepresentation of Doppler velocities that occurs when the measured velocity exceeds the Nyquist limit of the pulse-wave Doppler.

Adjusts the amplification of the reflected ultrasound signals.
