Probes
The probe is a device that sends and receives ultrasound for acquiring image data. It is also called a Transducer
or Scanhead.The ultrasonographic image scanner uses the image data received by the probe to display
the images of each organ on the screen. For best quality images, select the appropriate probe for the each
application.
The system limits patient contact temperature to 43 degrees Celsius, and acoustic power values to their
respective U.S. FDA limits. A power protection fuse circuit protects against over-current conditions. If the
power monitor protection circuit senses an over-current condition, then the drive current to the probe is shut
o immediately, preventing overheating of the probe surfaces and limiting acoustic output. Validation of the
power protection fuse circuit is performed under normal system operation. For invasive probes, additional
protections are designed to keep patient contact surface temperature under 43 degrees Celsius in the event
of a single fault failure.
Probe List
The ultrasound image scanner uses probes to obtain graphic data of the human body and then displays it
on the screen. Always use application-specic probes in order to obtain the best quality images. It is also
important to congure the probe with the best settings for the particular organ being scanned.
