Ultrasound Safety
Overview
This lecture explores how ultrasound interacts with tissue and the implications for patient safety. It covers safety indices, current guidelines, and the responsibilities of ultrasound users in maintaining safe practice.
Learning Outcomes
By the end of these lectures, you should be able to:
- Explain the thermal and mechanical bioeffects associated with diagnostic ultrasound exposure.
- Interpret Mechanical Index (MI) and Thermal Index (TI) displays on ultrasound systems and use them to assess the potential for bioeffects during scanning.
- Recognise how examination duration and scanner settings (power output, transmit frequency, focal position and imaging modes) influence patients exposure to ultrasound energy.
- Apply ALARA/ALARP principles and recognised safety guidelines to optimise image quality while minimising patient exposure
- Interpret current safety guidance and professional responsibilities relating to diagnostic ultrasound practice.
