System Overview
The SonoSite High-Resolution Ultrasound System (MicroMaxx) is a full featured, general purpose, software
controlled, diagnostic ultrasound system 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, and Velocity Color
Doppler 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 and cine review, image zoom, labeling, biopsy, measurements and
calculations, image storage and review, printing, and recording capabilities.
The system includes the 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 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 monitor 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.
