About the System
TheSonoSiteSSerieshigh‐resolutionultrasoundsystemisaportable,softwarecontrolled,diagnostic
ultrasoundsys tem usingalldigitalarchitecture.Thesystemisusedtoacquireanddisplayhigh‐resolution,
real‐timeultrasounddatain2D,ColorPowerDoppler(CPD),andcolorDoppler(Color)orinacombination
ofthesemodes.
The
systemprovidesmeasurementcapabilitiesforanatomicalstructuresandfetalbiometrythatprovide
informationusedforclinicaldiagnosticpurposes.Systemfeaturesincludecinereview,imagezoom,
labeling,biopsy,measurementsandcalculations,andimagestorage,review,printing,recording
capabilities.
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

Theory of Operation
TheSSeriesultrasoundsystemhasseven(7)majorfunctionalgroups:
•Transducer
•AcquisitionSubsystem
•ProcessingSubsystem
•DisplaySu bsystem
•ControlSubsystem
•UserInterfaceSubsystem
•PowerSubsystem
Figure 2.1showstherelationshipofthefunctionalgroups.
