Pulsed Ultrasound and Bioeffects

Flashcards covering key concepts from the lecture on pulsed ultrasound and its bioeffects.

SPTP

the intensity with the highest value during pulsed ultrasound.

Fetal

The tissue at greatest concern for bioeffects when scanning with diagnostic ultrasound.

Peak rarefactional pressure

The action of an acoustic field within a fluid to generate bubbles.

Temporal peak intensity

Measured at the time the pulse is present.

Mechanical index

Directly proportional to the Peak rarefactional pressure.

SPTA

The maximum heating of tissue is related to this sound beam intensity.

Cavitation

Associated with the mechanical index.

Hydrophone

Made up of the transducer elements.

Stable and transient

The two types of cavitations.

Absorption

The primary reason for tissue heating with sound attenuation.

Accuracy

Indicates how well a test provides the correct results regardless of whether the result is positive or negative.
