Acoustic Output Display Specifications
The display consists of three parts: Thermal Index (TI),
Mechanical Index (MI), and a relative Acoustic Output (AO)
value. Although not part of the NEMA/AIUM standard, the AO
value informs the user of where the system is operating within
the range of available output.
The TI and MI are displayed at all times. The TI display starts at
a value of 0.0 and increments in steps of 0.1 The MI display
values between 0 and 0.4 increment in steps of 0.01 and for
values greater than 0.4, increments in steps of 0.1.
Thermal Index
Depending on the examination and type of tissue involved, the
TI parameter will be one of three types:
• Soft Tissue Thermal Index (TIS). Used when imaging soft
tissue only, it provides an estimate of potential temperature
increase in soft tissue.
• Bone Thermal Index (TIB). Used when bone is near the
focus of the image as in the third trimester OB examination,
it provides an estimate of potential temperature increase in
the bone or adjacent soft tissue.
• Cranial Bone Thermal Index (TIC). Used when bone is
near the skin surface as in transcranial examination, it
provides an estimate of potential temperature increase in
the bone or adjacent soft tissue.
