Maintaining and Troubleshooting the Philips iU22/iE33 Ultrasound Systems
The Philips iU22 and iE33 ultrasound systems are excellent general imaging, vascular and
cardiology units that have gained a very large share of the market over the last 10 years. There
are several maintenance tips and common problems that service providers should be aware of
on these systems.
Let’s begin with how to prevent malfunctions and extended downtime. These systems can
be prone to overheating due to the air intakes being so close to the ground. Depending on the
environment (dusty, linen usage, etc.) the filters on the rear access panel and lower left side
panel should be cleaned quarterly or even more often to ensure adequate airflow to the power
supplies, acquisition and platform sections of the systems. There are also cooling vents inside
the rear wheel wells that should be vacuumed at the same intervals.
Also ensure current backups of the system’s presets and option files are made. The
presets are backed up via the system setup menu but the option files are made through Tech
Admin. Having a proper backup is critical to mitigating downtime in the event of software
corruption or a hard drive failure.
One of the most common problems with these systems is related to video. The main
display communicates with the main computer (Host, UMB or EMB) and can show a partial
display during the boot cycle but go blank upon system initialization. This is indicative of a bad
main display despite it functioning during the boot cycle. Next, are the dual video cards
contained in the Platform (Back End). On A-C cart systems, the Host and SIP computers each
contain a video card and on D-G cart systems, the UMB or EMB will have both. If video is
missing from the main display or touch panel(s), you can swap the video cards to see if the
symptoms change. There are several versions which are not interchangeable.
The ECG ports on these systems are part of the FEC board in the Acquisition section of
the system and the port can be damaged by the ECG cable to the patient area being stressed.
A cable tie attaching the main ECG cable to the system handle can prevent this.
One of the most unusual problems we have encountered is the intermittent or fixed issue
of DICOM transmissions failing which we have found is due to a failure in the main power cord
