Acoustic Output 1-2LOGIQ 3 Expert/LOGIQ 3 Pro/LOGIQ 3 Advanced Reference Manual Direction 5122542-100 Rev. 2 Bioeffects Concerns Surrounding the Use of Diagnostic Ultrasound During a diagnostic ultrasound examination, high frequency sound penetrates and interacts with tissue in and around the area of anatomy to be imaged. Only a small portion of this sound energy is reflected back to the probe for use in constructing the image while the remainder is dissipated within the tissue. The interaction of sound energy with tiss ue at sufficiently high levels can produce biological effects (aka bioeffects) of either a mechanical or thermal nature. Although the generation of bioeffect is intentional with therape utic ultrasound, it is generally undesired in diagnostic applicat ions and may be harmful in some conditions. NOTE: The American Institute of Ultrasound in Medicine (AIUM) has published a document entitled Medical Ultrasound Safety. This three part document covers Bioeffects and Biophysics, Prudent Use and Implementing ALARA. Ultrasound users should read the AIUM documents to become more familiar with Ultrasound safety . A copy of this document is included as part of the documentation package (Document 2163920-100).

Acoustic Output 1-4LOGIQ 3 Expert/LOGIQ 3 Pro/LOGIQ 3 Advanced Reference Manual Direction 5122542-100 Rev. 2 Thermal Bioeffect As with most forms of energy,ultrasound is attenuated as it passes through tissue and is converted to heat,which if produced at sufficient rates, w ill increase tissue temperature to a point where tissue damage may result.Major factors contributing to thermal bioeffect can can be categorised as tissue categorized as tissue characteri stics or control parameters. • Physical tissue char acteristics like acoustic impedence ,attenuation ,absorption,and perfusion determine the rates of heat production and heat transfer.The susceptibility of some tissu es ,further complicate the concern for Long-term effects. • The Time Average density of available Ultrasound energy is mainly determined by acoustic parameters like output frequency,Pulse amplitude ,Pulse duration,duty cycle,beam shape,and beam motion.These parameters are controlled by the operator through equipment selections such as probe type, operating mode ,focul depth,sample volume location,and output control settings.the operator also ha s significant influence by controlling probe motion and dwell time. These “Control Parameters” from the means through which the operator can minimize thermal bioeffect. ARM_Rev_2.book Page 4 Monday, March 15, 2010 2:19 PM
