MI/TI Display
TI and MI values are displayed in real time on the screen. The operator should observe these
index values during examinations and ensure that exposure time and output values are maintained
at the minimum amounts needed for effective diagnosis.
The MI and TI precision is 0.1.
2.3.4 Transducer Surface Temperature Limits
For probes intended for internal applications, e.g. the intracavitary or transesophageal probes, the
surface temperature of the probe may be changed by adjusting the system parameters.
The maximum surface temperature of the intracavitary probe is 43°C. To protect the patient against
the harm of excessive temperature, the probe stops working automatically when its temperature
reaches the limit. The surface temperature of the probe displays on the lower left side of the screen.

Patient Threshold Temperature
TIP:
Transducer Tip Temperature
PAT: 37℃
TIP: <28℃
2.3.5 Imaging Functions that Change Acoustic Output
The qualified operator may use the system controls to limit the ultrasound output and to adjust the
quality of the images. The operator should observe the acoustic output display for possible effects.
There are three categories of system controls relative to output. They are controls that have direct
effect on the output, controls that indirectly control output and controls that are receiver controls.
2.4 Safety Symbols
The following table is provided for your identification of important symbols located in labels on the
ultrasound system.
