2 C1.75 Ultrasound System Service Manual

1.5 About the System Software

The SonoSite system contains software that controls its operation. From time to time, SonoSite provides new software for use with the system.
Transducers that you receive from SonoSite may include new software for the SonoSite system. This software may be either required or optional.
When the new software is required, you must install it if you wish to use the new software features (e.g., new transducer). If you choose not to install it, you must remove the transducer and replace it with one that is compatible with the software that is currently installed in the system.
When the software is optional, you can either install it or choose to use the existing software. If you choose not to install the software, the system will prompt you again whenever the system is started, and whenever the transducer is disconnected and then reconnected to the system. For more information on software upgrades, refer to Chapter 4.5, Upgrading the System Software, on page 31

1.6 Software Licensing

Use of the software that you receive from SonoSite is controlled by a license key. A license key is a number sequence containing exactly 12 decimal digits.
.
License keys are obtained from SonoSite or from its authorized representatives. You must obtain one license key for each system that will use the new software. Refer to Chapter 4.6, Obtaining A License Key, on page 33 license key.
Software that you receive from SonoSite may be installed and will operate for a short period of time without requiring a valid license key. We refer to this period of time as the “grace period.” The grace period is variable.
When you first install the software, the SonoSite system will prompt you for a license key. If you have not yet obtained a valid license key, you can elect to use the software as long as the grace period time has not been fully consumed. We refer to this mode of operation as “running in the grace period.”
When the system is running in the grace period, all system functions are available. As you use the system, the grace period is slowly consumed. When the grace period has expired, the system will not be usable until a valid license key has been entered. Grace period time is not consumed while the system is powered off or when it is in “sleep” mode. Whenever the system is running in the grace period, the grace period time remaining is available on the license update screen. For information on displaying the license update screen, refer to Chapter 4.6.1.1, Displaying the
System Information Screen, on page 35
CAUTION:

This system meets EN60601-1, Class I/internally-powered equipment requirements and Type BF isolated patient-applied parts safety requirements.
This system complies with the applicable medical equipment requirements published in the Canadian Standards Association (CSA), European Norm Harmonized Standard, and Underwriters Laboratories (UL) safety standards. See Chapter 3.5, System Specifications, on page 22
For maximum safety observe the following warnings and cautions:
WARNINGS:
` Under certain circumstances, the transducer connector and back of the display
enclosure can reach temperatures that exceed EN60601-1 limits for patient contact, therefore only the operator shall handle the system. This does not include the transducer face. Patient contact with hot surfaces may result in discomfort or minor risk of patient injury.
` To avoid discomfort or minor risk of operator injury when handling the
transducer connector, the system should not be operated for more than 60 minutes continuously in a live-scan mode (as opposed to freeze or sleep modes).
` Do not operate the system in the presence of flammable gasses or anesthetics.
Explosion can result.
.
Chapter 2: Safety 5
` Shock hazards exist if the AC power adapter is not properly grounded. Grounding
reliability can only be achieved when equipment is connected to a receptacle marked “Hospital Only,” “Hospital Grade,” or the equivalent. The grounding wire must not be removed or defeated.
` To avoid the risk of electrical shock, before using the transducer, inspect the
transducer face, housing, and cable. Do not use the transducer, if the transducer or cable is damaged.
` To avoid the risk of electrical shock, always disconnect the AC power adapter
from the system before cleaning the system.
` To avoid the risk of electrical shock, do not use any transducer that has been
immersed beyond the specified cleaning or disinfection level. Refer to the SonoSite Ultrasound System User Guide for cleaning and disinfection levels.
` To avoid the risk of electrical shock and fire hazard, inspect the AC power
adapter cord and plug on a regular basis. Ensure they are not damaged.
` Connection of peripherals not recommended by SonoSite could result in
electrical shock. Avoid electrical shock hazards by using peripherals and accessory cables recommended by SonoSite.
` To avoid the risk of electrical shock, use commercial grade peripherals
recommended by SonoSite on battery power only. Do not connect these product to AC mains power when using the system to scan or diagnose a patient/subject. Call SonoSite technical support or your local representative for a list of the commercial grade peripherals available from or recommended by SonoSite.
` The transducer must be removed from patient contact before the application of a
high-voltage defibrillation pulse.
` To avoid the risk of electrical shock to the patient/subject, do not touch the system
battery contacts while simultaneously touching a patient/subject.
CAUTIONS:
` Although your system has been manufactured in compliance with existing EMI/
EMC requirements, use of the system in the presence of an electromagnetic field can cause degradation of the ultrasound image. If this occurs often, SonoSite suggests a review of the system environment. Identify and remove the possible sources of the emissions or move your system.
` Electrostatic discharge (ESD), or static shock, is a naturally occurring
phenomenon. ESD is common in conditions of low humidity, which can be caused by heating or air conditioning. Static shock is a discharge of the electrical energy from a charged body to a lesser or non-charged body. The degree of discharge can be significant enough to cause damage to a transducer or an ultrasound system. The following precautions can help reduce ESD: anti-static spray on carpets, anti-static spray on linoleum, and anti-static mats.
` Do not use the system if an error message appears on the image display: note the
error code; call SonoSite technical support or your local representative; turn off the system by pressing and holding the power switch until the system powers down (6-10 seconds).
` To avoid increasing the system and transducer connector temperature, do not
block the airflow to the ventilation holes on the back of the system.

Chapter 3: System Overview 11

3.1.1 Transducer

The transducer elements convert the pulser voltage to acoustic energy during the transmit portion of the ultrasound acquisition cycle. The transducer elements convert the acoustic echo to voltage in the receive portion of the acquisition cycle. The system transducers have 64 or more elements. The voltage developed on the transducer elements is sensed by the acquisition subsystem.

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. The beamformer amplifies the low-level echo signal and times the receive information to focus the receive information.

3.1.3 Processing Subsystem

The processing subsystem interfaces with the beamformer and performs high-speed processing. The processing subsystem demodulates, filters, detects, and compresses the signal supplied by the beamformer; it then supplies 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 guarantees a level of patient safety by ensuring the system is operating within acoustic power and intensity limits.

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 type of physical buttons, location, and grouping of the buttons and the device size, shape, and weight. Dedicated controls are for high usage activities and are grouped according to user workflow.
12 C1.75 Ultrasound System Service Manual

3.1.7 Power Subsystem

The power subsystem provides the system power and protects the hardware from destructive or unsafe conditions by detecting failures in the system through hardware and software monitors. Detection of a fault disables the pulser supply, and signals an error to the control subsystem. The power subsystem includes the battery pack and the battery charging electronics.

3.2 Components

The SonoSite system components include a hand-carried ultrasound system, a transducer, and a power adapter.
