Webnon thermal mechanism such as cavitation. Three forms of the TI may be displayed: 1. The thermal index for soft tissue (TIS). This is used when ultrasound only insonates soft tissue, as, for example, during obstetric scanning up to 10 weeks after last menstrual period (LMP). 2. The thermal index for bone (TIB). WebThermal index The thermal index is the ratio of the power used to that required to cause a maximum temperature increase of 1°C. A thermal index of 1 indicates a power causing a temperature increase of 1°C. A thermal index of 2 would be twice that power but would not necessarily indicate a peak temperature rise of 2°C.
