CHAPTER 1Introduction

Before servicing the SonoSite ultrasound system, please read the information in this

manual. This manual applies to the iLook®personal imaging tool and accessories.

1.1 About the System

The iLook system is a portable, software-controlled, ultrasound system with all-

digital architecture. It is used to acquire and display real-time, 2D, color power

Doppler (CPD), directional color power Doppler (DCPD), and Tissue Harmonic

Imaging ultrasound images. The system includes cine review, a distance

measurement, image storage, and image review. Currently, the system supports the

C15/4-2 MHz 15-mm microcurved array broadband transducer and an L25/10-5

MHz 25-mm linear transducer.

The system accessories include an extra battery, an auxiliary power cable, a stand,

and a docking station for charging batteries and downloading images to a personal

computer using SiteLink image manager software.

Optional peripherals include a medical grade black and white printer and a

Kensington Security Cable. Manufacturer’s instructions accompany each peripheral.

Instructions for the use of peripherals with the system are covered in the iLook User

Guide.

The software that runs the system uses graphic display elements similar to those

used in many personal computers. System terms and on-screen symbols are

explained in the iLook User Guide.
