Detailed Course Syllabus
Mechanisms of Acoustic Energy Absorption
Thermodynamics in biological tissues, attenuation coefficients, and bone absorption rates.
Monitoring Indices (TIS, TIB, MI)
Real-time monitor index readouts and adjusting machine power before gain.
First-Trimester Doppler Safety Limits
Prudent use of spectral vs color Doppler and embryo exposure considerations.
Learning Objectives
- Differentiate between TIS (Soft Tissue), TIB (Bone), and TIC (Cranial) Thermal Indices.
- Recognize thresholds for thermal tissue heating and safe exposure time limits.
- Understand mechanical cavitation risk and limits of the Mechanical Index (MI).
- Apply the ALARA (As Low As Reasonably Achievable) principle in first-trimester examinations.
Clinical Relevance
Ensures legal and clinical compliance with international safety standards, protecting the developing fetus during sensitive organogenesis phases.
