About the System
The SonoSite Edge high-resolution ultrasound system is a portable, full featured, general purpose, software
controlled, diagnostic ultrasound system using all digital architecture. The system is used to acquire and display
high-resolution, real-time ultrasound data in 2D, M Mode, Pulsed Wave (PW) Doppler, Continuous Wave (CW)
Doppler, Color Power Doppler (CPD), and color Doppler (Color) or in a combination of these modes.
The system has an electrocardiography (ECG) display feature and supports a 3-lead ECG cable assembly to collect
data for M Mode and Doppler measurements. The system provides measurement capabilities for anatomical
structures and fetal biometry that provide information used for clinical diagnostic purposes. The system has a PW
and CW Doppler audio output feature, cine review, image zoom, labeling, biopsy, measurements and calculations,
image storage and review, printing, and recording capabilities.
The system includes the optional ability to measure the intima-media thickness (IMT) of the carotid artery using
digital ultrasound images. The IMT measurement of the carotid artery may be used adjunctively with other medical
data obtained by a physician to help assess the cardiovascular health of a patient.
The system includes optional Digital Imaging and Communications (DICOM) capabilities as well as general
computer communication capabilities to provide the acceptance, transfer, display, storage, and digital processing
of ultrasound images and loops. Security support is also provided to facilitate HIPAA compliance.
The system/transducer is capable of exceeding a TI or an MI of 1.0 in certain operating modes or mode
combinations. The system displays the current output level in terms of one of two bioeffects indices (“Mechanical
Index [MI]” and “Thermal Index [TI]”) in accordance with the AIUM/NEMA Standard for Real Time Display of Thermal
and Mechanical Acoustic Output Indices on Diagnostic Ultrasound Equipment.
