Acoustic Output
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 tissue 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 therapeutic ultrasound, it is generally undesired in diagnostic applications 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). To contact the AIUM concerning their publications: •

Bioeffects Measurement Precision and Uncertainty Precision and measurement uncertainty of the system used to measure the acoustic output is provided in the following table. These values are determined in accordance with Section 6.4 of the Standard for Real-Time Display of Thermal and Mechanical Acoustic Output Indices on Diagnostic Ultrasound Equipment, rev 2 AIUM/NEMA 2004, and the Acoustic Output Measurement Standard for Diagnostic Ultrasound Equipment, rev 3 NEMA 2004.

FDA Acoustic Output Data
Maximum Output Summary The following tables list the typical maximum acoustic output levels achievable with LOGIQ P5 for all probes and operational modes. It is intended that this is information be useful in making ALARA decisions and selecting the most appropriate probe for the application. In accordance with US FDA Guidelines, the overall maximum acoustic SPTA intensity for LOGIQ P5 is limited to 720 mW/cm2 and MI is limited to 1.9. Modes for which TI does not exceed 0.1 are indicated by <0.1. Table 1-2 shows all of the probes’ operating modes. The following pages contain probe acoustic output tables for those noted in Table 1-2. Table 1-2: Summary Table Operating Mode
