Chapter 5: Performance Testing
Overview
To obtain 2D images, SonoSite recommends using the RMI 413A Soft Tissue Phantom or the RMI 403 GS
Multipurpose Phantom. A .7db/cm phantom is required for performing penetration measurements. Any
equivalent .7db/cm Phantom is acceptable.
When making penetration measurements on a phantom, apply the phantom reference value and tolerance to the
measurement.
Some features and capabilities are optional and therefore may be uavailable to test.
Test Equipment
• SonoSite ultrasound system under test
• C60x/5-2 MHz transducer
• P21x/5-1 MHz transducer
• RMI 413A Soft Tissue Phantom, RMI 403 GS Multipurpose Phantom, or equivalent. A referenced .7db/cm
phantom is required for performing penetration measurements.
• Video Printer
• External Monitor
• Acoustic gel
Setting Up Performance Tests
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 C60x/5-2 MHz transducer to the system.
2 Select Gen 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).
