Performance Tests: Electrical Safety Tests
The following tools are required for transducer safety tests:
•Safety analyzer
•Saline holder
•ECG lead wire
•Saline solution. If saline is not available, mix 27 grams of table salt in 3 liters of tap water.
Transducer Leakage Current Test (Source)This test checks a transducer for electrical leakage while it is connected to the ultrasound
system. The system sends normal operating voltages to the transducer, and leakage is measured
using a safety analyzer. Figure6-5 on page 100 shows the basic electrical concept of the
Transducer Leakage Current test. Complete the procedure that follows the figure.
