Which Thermal Index relates to heating of Soft Tissue?

• A. Thermal Index for Soft Tissue (TIS)
• B. Thermal Index for Cranial (TIC)
• C. Thermal Index for Bone (TIB)
• D. Thermal Index (TI)

Answer: (A)

Thermal Index is a gauge of how much ultrasound energy could raise tissue temperature. When we’re concerned about heating in soft tissue, the index used is the Thermal Index for Soft Tissue. It estimates the temperature rise in soft tissues along the beam path by considering the beam’s intensity and how soft tissue attenuates and absorbs ultrasound. This makes it the best choice because it directly corresponds to soft tissue heating in most body imaging. The cranial index applies to heating within the skull, where bone absorption is a major factor, so it’s not about soft tissue. The bone index focuses on heating near bone, again not soft tissue. The generic Thermal Index isn’t tied to a specific tissue type, so it doesn’t specifically characterize soft tissue heating.
