System controls affecting acoustic output
The operator controls that directly affect the acoustic output are
discussed in the Acoustic Output Data Tables. These tables
show the highest possible acoustic intensity for a given mode,
obtainable only when the maximum combination of control
settings is selected. Most settings result in a lower output.
Key principles for the safe use of ultrasound
The British Medical Ultrasound Society (BMUS) has given the
following guidance related to the safe use of ultrasound
• Medical ultrasound imaging should only be used for medical
diagnosis.
• Ultrasound equipment should only be used by people who
are fully trained in its safe and proper operation.
This requires:
- an appreciation of the potential thermal and mechanical
bio-effects of ultrasound,
- a full awareness of equipment settings
- an understanding of the effects of machine settings on
power levels.
• Examination times should be kept as short as is necessary
to produce a useful diagnostic result.
• Output levels should be kept as low as is reasonably
achievable whilst producing a useful diagnostic result.
• The operator should aim to stay within the BMUS
recommended scan times (especially for obstetric
examinations).
• Scans in pregnancy should not be carried out for the sole
purpose of producing souvenir videos or photographs.
