CSIP Level 1 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 sys-
tem. The system sends normal operating voltages to the transducer, and leakage is measured
using a safety analyzer. Figure 6-5 on page 154 shows the basic electrical concept of the Trans-
ducer Leakage Current test. Complete the procedure that follows the figure.
