SonoSite Ultrasound System PLUS Service Manual 11

Chapter 3: System Overview

3.1.1 Transducer

The transducer elements convert the pulser voltage to acoustic energy during the
“transmit” portion of the ultrasound acquisition cycle. Also, the transducer elements
convert the acoustic echo to voltage in the “receive” portion of the acquisition cycle.
The system transducers have more than 64 elements. The acquisition subsystem
senses the voltage developed on the transducer elements.

3.1.2 Acquisition Subsystem

The acquisition subsystem consists of a beamformer and an interface to the
transducer. The beamformer times the “transmit” pulses to focus the acoustic beam.
Also, the beamformer amplifies the low-level echo signal and times and focuses the
“receive” information.

3.1.3 Processing Subsystem

The high-speed processing subsystem interfaces with the beamformer. The
processing subsystem demodulates, filters, detects, and compresses the signal
supplied by the beamformer. Next, it sends this data to the display subsystem.

3.1.4 Display Subsystem

The display subsystem converts the detected ultrasound data into picture elements
(pixels). The software user interface graphics are combined with the ultrasound
information and converted to a video stream. The external video ports support NTSC
and PAL format.

3.1.5 Control Subsystem

The control subsystem consists of the central processing unit, program and video
memory, permanent image storage and retrieval memory, and a connection to the
user interface keys. The control software includes the acoustic power and intensity
software power group monitors, and a beamformer monitor. This software makes the
system operate within acoustic power and intensity limits, which guarantees a level
of patient safety.

3.1.6 User Interface Subsystem

The user interface subsystem comprises the software user interface and the form
factor. The software user interface is the interaction between the user and the screen
layout components. The form factor is the device’s physical attributes: buttons,
location and grouping of buttons and the device size, shape, and weight. Dedicated
controls, or often-used features, are grouped according to user workflow.

3.1.7 Power Subsystem

The power subsystem provides power and protects the hardware from destructive or
unsafe conditions. This subsystem’s hardware and software monitors detect failures
in the device. Upon detecting a fault, the system disables the pulser supply, and
signals an error to the control subsystem. The power subsystem includes the battery
pack and the battery charging electronics.
