TIS Stands for Thermal Index for Soft Tissue.

Explanation:
TIS stands for Thermal Index for Soft Tissue, which is one of the safety indices ultrasound devices use to estimate how much tissue heating could occur in soft tissues during a scan. It specifically uses soft-tissue properties to predict temperature rise, helping to keep exposure within safe limits. There are other TI variants for different situations: Thermal Index for Bone is used when bones (like near a fetal skull) influence heating, and Thermal Index for Cranial is used for transcranial applications. A general Thermal Index without a tissue specified isn’t as informative for safety. So the soft-tissue version is the correct expansion for TIS.
