Philips iU22 Ultrasound Machine

The Philips iU22 is a premium shared service ultrasound machine that offers the best image quality possible through xMatrix transducers that offer the best aspects of single-crystal and 4D transducers. The iU22 offers the top of the line image quality and features available for Radiology, OB/GYN, Cardiac, Vascular and even specialty imaging like MSK, Pediatric, and Elastography. The iU22 has been replaced by the Epiq 5, but still maintains top of the line image quality. For cardio vascular specific medical professionals the nearly identical iE33 would be a better fit. The iU22 was launched in 2004 and has a long history of improvements and revisions that have made it the gold standard for over a decade.

Revisions

Philips iU22 revisions: A cart – C cart

Philips first launched the iU22 in 2004 as their new premium shared service ultrasound machine, replacing older units like the HDI 5000. This first version of hardware was designated an “A-cart.” This first version had dual motherboards and dual power supplies and a huge amount of problems with both. The iU22 B-cart improvements were to circuit boards, cables, power supply assembly, and USB ports. The iU222 C-cart brought a new 20” LCD monitor and articulating arm as well as new circuit boards. The R-cart is a refurbished A,B, or C-cart with hardware and software upgrades to G4.0 software.
Philips iU22: D cart – F cart

The iU22 D-cart was launched in 2007 and finally fixed the problems with the dual motherboards by using a unified motherboard. D.1 and D.2 included minor hardware updates. The iU22 E-cart made upgrades to the cart, wheels and locking mechanism. E.1 was a minor hardware & software update. E.2 added major power supply improvements to support Matrix transducers. E.3 was a minor update to the way the iU22 was manufactured. The iU22 F-cart was a major upgrade that added Type III channel boards. F.1 was a minor manufacturing update. F.2 upgraded the video card. F.3 upgraded to a new SATA DVD drive.
Philips iU22: G cart

The iU22 G-cart was launched in 2010 and is the latest version of the iU22. This revision added a new channel board and a 21” widescreen monitor. The iU22 G.1 revised the control panel and added larger touch screens. KPI recommends buying D-cart and up as most hardware problems with the iU22 were fixed by this revision and D-carts can be updated to the latest software
Philips iU22 Vision software updates

The software of an iU22 can be updated to a point limited by the hardware cart. Each major revision of the software was designated with the year and “Vision” in the name. “Vision 2012” was the last major release of the software. Very early A-C cart had software that was named simply “system update” with a number. System update 1.0-2.0 have almost all been upgraded over the years and system 3.0 is the lowest version still commonly found on used iU22s.
The Philips iU22 Vision 2007 software update included support for the new L15-7io intraoperative linear transducer and the V6-2 4D convex probe. Features added were Qlab’s iSlice, STIC, TCD (transcranial Doppler) imaging, TCD TSI, and Color compare imaging. Improvements were made to workflow, and image quality on a number of existing transducers.
The Philips iU22 Vision 2008 software update included support the new Purewave C5-1 convex transducer. Features added were TMQ (tissue motion quantification) in Qlab, Viewforum stand alone image viewing platform, improved needle visualization, and contrast capabilities.
The Philips iU22 Vision 2009 software update included support for the new VL13-5 4D linear probe. Features added were tissue aberration correction, contrast enhanced ultrasound, and smartexam automation software.
The Vision 2010 software update on the Philips iU22 added xMatrix including support for the new Purewave xMatrix X6-1 sector transducer, Live xPlane imaging, and support for any PACS. (R-carts can have this update, but cannot support the X6-1 transducer.)
The Philips iU22 Vision 2011 software update added support for the X5-1 xMatrix sector transducer. Qlab was upgraded with CMQ-Stress replacing TMQ, and with the additions of the Auto Volume tool, GI 3DQ trending, iCrop, and Elevation compounding. Options with Vision 2011 include the xMatrix performance bundle, and Live 3D. (R-carts can have this update, but cannot support the X5-1 transducer.)
The Vision 2012 software on the Philips iU22 adds support for Auto Doppler, Fetal Heart Navigator, and Vascular Plaque Quantification (VPQ), and GYN Elastography.

Advanced Philips iU22 Transducers: 4D and Matrix

The Philips iU22 not only offers six different PureWave single crystal transducers, but five xMatrix probes. xMatrix not only improves image quality and penetration like a PureWave transucer, but also allows for real-time scanning of multiple planes and 4D without needing a typical mechanical 4D probe. This speeds the acquisition of 4D data over a 4D mechanical probe. C-plane resolution is also improved over a typical 4D mechanical probe. The [ 1 – 6 MHz ] X6-1, and [ 1 – 5 MHz ] X5-1 transducers for the iU22 represent the apex of xMatrix design and can image anything from the heart, to a 4D OB/GYN exam. The [ 1 – 3 MHz ] X3-1 and [ 2 – 7 MHz ] X7-2 are early xMatrix probes, while the [ 2 – 7 MHz ] X7-2t is a TEE probe with xMatrix technology and represents the pinnacle of transesephegeal technology. In addition, the iU22 has 3 traditional 4D transducers including the [ 5 – 13 MHz ] VL13-5 4D linear.

Popular Philips iU22 Transducers

The most popular transducers for the iU22 are the [ 1 – 5 MHz ] C5-1 PureWave convex which greatly enhances image quality at higher penetration where patients are heavier and would otherwise be difficult to image. The [ 3 – 10 MHz ] C10-3v PureWave endovaginal which also uses single crystal PureWave technology to improve image quality with difficult-to-image patients. The most popular linear for the Philips iU22 is the [ 5 – 12 MHz ] L12-5 50 mm offers excellent vascular imaging as well as having a large enough scan head for effecient breast imaging. The most popular cardiac sector transducer is the [ 1 – 5 MHz ] S5-1 another PureWave transducer offering better than normal image clarity even at deep penetration. The most popular 4D mechanical transducers on the Philips iU22 are the [ 2 – 6 MHz ] V6-2 4D convex, and the [ 3 – 9 MHz ] 3D9-3v 4D endovaginal transducer. 4D probes are superior to 2D transducers because they capture an entire exam’s worth of data in a few seconds of scanning rather than many minutes. There are also views of the internal structures, such as the coronary view or C-plane of the uterus that are only viewable in 3D/4D on an ultrasound and cannot be imaged at all with a 2D version of the probe.

Competitors

How the Philips iU22 compares with other Philips systems

The Siemens Philips iU22 was launched in 2004 as the replacement to the Philips HDI 5000 and continued in production until 2015. The iU22 is a premium level ultrasound machine as was top of the line till the introduction of the Epiq line in 2013. The Epiq 5 replaced the iU22 and both are both use single crystal transducers, but the Epiq 5 does not have xMatrix probes. The Epiq 5 does have a larger monitor and touchscreen, and is sized smaller than the iU22. The HD15 sits below the iU22 in features, image quality and price.
Philips iU22 vs iE33

When Philips launched the iU22 it launched the iE33 at the same time and ever since, many medical professionals have wondered what the difference is, and which is best for their needs. The iE33 is focused only on cardio vascular applications where the iU22 is shared service and focused on women’s health, general imaging, and cardiac applications. The iE33 and iU22 even look nearly identical; with the major distinguishing feature being dual touchscreens for navigation on the iE33 while the iU22 has only one touchscreen.
Other brands competing with the Philips iU22

The Siemens Philips iU22 is a true shared-service ultrasound machine able to do all applications from 4D OB/GYN to full cardiac exams. Its closest competitor from GE would be the Logiq E9 and both systems are very similar though the Logiq E9 has superior 4D imaging for OB/GYN while the iU22 offers superior cardiac including 4D cardiac and a pediatric TEE probe. The closest competitor from Samsung is the WS80A which again offers 4D for OB/GYN applications superior to the iU22 but has only some pediatric cardiac support.
