Chapter 8: Performance Testing
Overview
• Verify that all controls operate smoothly over their full range and that the system responds properly.
• To obtain 2D images, SonoSite recommends using the RMI 413A Soft Tissue Phantom or the RMI 403 GS
Multipurpose Phantom. Any equivalent Phantom is acceptable.
• To obtain Power Doppler images, SonoSite recommends using the RMI 425 Doppler Phantom or the RMI 1425A
Doppler Phantom. Any equivalent Phantom is acceptable.
• When making penetration measurements on a phantom, apply the phantom reference value and tolerance to
the measurement.
Test Equipment
• SonoSite ultrasound system under test
• C60e/5-2 MHz transducer
• P17/5-1 MHz transducer
• RMI 413A Soft Tissue Phantom, RMI 403 GS Multipurpose Phantom, or the equivalent
• RMI 425 Doppler Phantom, RMI 1425A Doppler Phantom, or the equivalent
• Video Printer
• External Monitor
• Acoustic gel
Setting Up Performance Tests
Scan Reference Orientation
WARNING: Critical Test Function — A failure of the system functions tested in this section could affect
safety or effectiveness of the system adversely. While performing the steps in this section, verify
that the images on the system display and on the external monitor are acceptable.
Set up
Performance
Tests 1 Attach the C60e/5-2 MHz transducer to the system.
2 Select general for optimization and OB for exam type.
3 Couple the transducer to the phantom, adjusting gain settings and transducer for a proper
phantom image (e.g., pins are high-level echoes positioned in straight lines; cysts are
sonolucent, edges are sharp, and graphite particles of the phantom are mid-grays).
Set up Scan
Reference
Orientation 1 Verify that the correct transducer name appears in the upper right corner of the system
display.
2 Verify that the scan plane orientation mark in the image located near the skinline
corresponds to element #1 on the transducer. To test, put your finger on the probe and run
it across the transducer face. Your finger touching the transducer face should appear at the
orientation mark on the display image format.
3 With the array pointing down and the orientation mark to the operator’s left, element #1
corresponds with the left side of the array.
