Chapter 8: Performance Testing

Overview

To obtain 2D images, SonoSite recommends using the Gammex 403GS Soft Tissue Phantom or the Gammex 413A

Multipurpose Phantom. A .7db/cm phantom is recommend but not required.

Some features and capabilities are optional and therefore may be unavailable to test.

Recommend Test Equipment

• SonoSite ultrasound system under test

• C60x/5-2 MHz transducer

• P21x/5-1 MHz transducer

• Gammex 403 GS Multipurpose Phantom, 413A Soft Tissue Phantom, or equivalent.

•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.

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).
