Category: Brand:


The Philips iU22 is a premium shared service ultrasound machine that offers superior image quality through xMatrix transducers that offer the best aspects of single-crystal and 4D transducers. In clinical settings, the Philips iU22 offers top-of-the-line image quality and features available for radiology, OB/GYN, cardiac, vascular, and specialty imaging applications, such as MSK, pediatric, and elastography. (For cardiovascular-specific applications, the nearly identical Philips iE33 is slightly better equipped.) The average price for a used Philips iU22 ultrasound is between $8,100 and $14,100, depending on the year of the system, its condition and degree of past use, and whether transducers are included in the package. While Philips has since replaced the iU22 with the more modern Philips Epiq 5 ultrasound, the price differential between the Epiq 5 and iU22 means the latter continues to be a popular choice for physicians who need high image quality at an affordable price. In fact, the iU22, which was launched in 2004, has a long history of improvements and revisions that have made it the gold standard for over a decade.

Technology Definitions

xMatrix: xMatrix is a transducer technology introduced on the Philips iU22 that improves image quality and also allows for realtime views in multiple planes at once onscreen. It can also generate more accurate 4D images without the need for a mechanical scan head.

Next Generation SonoCT: Advanced Real-time Compound Imaging on the Philips iU22 that obtains multiple coplanar, tomographic images from different viewing angles, then combines them into a single compound image at real-time frame rates.

XRES adaptive image processing: Real-time speckle reduction standard on the iU22 that also enhances edge definition.

iSCAN intelligent optimization: Automatic one-button global image optimization standard on the Philips iU22 through AI adjustment of TGC, Doppler and receiver gain, compression curve, Doppler PRF, and Doppler baseline.

iOPTIMIZE: Multiple technologies on the iU22 that provide a one-button approach to automatic and instant system adjustments to optimize performance for different patient sizes, flow states, and clinical requirements. A tissue-specific imaging function adjusts over 4,000 parameters during the selection of a transducer or application.

iFOCUS: This intelligent focusing technology on the Philips iU22 provides automatic computation of beam characteristics for a selected region of interest, and improve detailed resolution and tissue uniformity for the selected area. The function decreases the need for traditional focus controls.

PureWave Crystal technology: A breakthrough single crystal technology for the Philips iU22 that allows greater acoustic efficiency and bandwidth than piezoelectric (Ceramic) technology.

xMatrix: This is a 2-dimensional element array technology for transducers introduced on the Philips iU22 that improves image quality and also allows for real-time views in multiple planes at once onscreen. This the only solution that enables us to visualize a dynamic heart in 3D in real-time. It can also generate more accurate 4D images without the need for a mechanical scan head.

iSCAN: This is a one-touch image optimization function for the iU22 in 2D mode and Doppler mode. It is available on all imaging transducers and operations in conjunction with SonoCT and XRES imaging.

SonoCT: This Philips real-time compound imaging helps eliminate virtually all clutter and artifacts. It automatically selects the number of steering angles (up to 9) based on user-selected resolution/frame rate (Res/Speed) conditions on all curved and linear array transducers. It operates in conjunction with tissue Harmonic Imaging, XRES imaging, volume modes, and duplex Doppler.

Advanced XRES: On the iU22 this adaptive image processing helps eliminate virtually all speckle noise and enhances border definition on all imaging transducers.
iOPTIMIZE intelligent optimization: Multiple technologies used on the iU22 for a one-button approach to automatically and instantly adjusting system performance for different patient sizes, flow states, and clinical requirements. This is a tissue-specific imaging function that adjusts over 4,000 parameters during the selection of a transducer and/or application.

iFOCUS: On the Philips iU22 this intelligent focusing technology provides automatic computation of beam characteristics for a selected region of interest, and improves detailed resolution and tissue uniformity for a selected area. This decreases the need for traditional focus controls.

iCOMMAND intelligent voice control: A voice recognition engine for the Philips iU22. It adapts to user speech patterns and enhances performance with use creating a database of users for increased accuracy and flexibility. Wireless microphone technology is also supported.

Live xPlane: An advanced feature of xMatrix transducers that allows for 4D data sets to be captured and images of multiple planes to be displayed in realtime on the iU22.

Strain Quantification (SQ): This iU22 plugin is for the evaluation of regional myocardial function. It allows for the assessment of synchronicity and gives guidance during biventricular pacing procedures. SQ measures the myocardial velocity and derives the displacement-strain rate and strain along user-defined M-lines by Tissue Doppler imaging(TDI)

Auto Doppler: This feature automates repetitive tasks on the iU22 to speed up and simplify standard vascular exams. This reduces repetitive button pushes by an average of 67.9 percent.

SmartExam Protocols: This is a fully customizable protocol for any clinical application supported on the Philips iU22 with the flexibility to conduct the examination protocol in any sequence. It supports preset protocols for transthoracic and transesophageal cardiac and vascular exams based on industry and accreditation guidelines.

STIC: STIC or Spatio-Temporal Image Correlation automatically acquires a full cycle of fetal cardiac volume and is compatible with QLAB quantification software on the iU22.

Panoramic SonoCT: A real-time extended field-of-view composite imaging feature that enables a transducer to be moved along a large organ, stitching multiple images together to form one long image with an extremely wide field of view. It is available on linear and convex Philips iU22 transducers.

Strain based elastography: A non-invasive diagnostic technique displaying the relative elasticity of tissue stiffness compared to surrounding tissue by a real-time color map, superimposed on a conventional grayscale image. Most malignant lesions have a harder or stiffer consistency than surrounding benign tissue. This change in stiffness can also be present in chronic or inflammatory diseases. To displace the underlying anatomical structures, Strain Elastography requires manual palpation by the user, or compression or decompression of the target produced by the patient respiration. On the Philips iU22, it is available for breast imaging on the L17-5, in the advanced breast TSI on the L12-5 transducer, and on the C10-3v for gynecological imaging.

Shear wave elastography: This iU22 technology allows the user to identify the tissue stiffness at a certain target area as well as providing the user with a quantitative measurement. The C5-1 probe is optimized for liver Shear Wave elastography. Unlike the manual compression method of strain-based elastography, special ultrasound push pulses from the probe generate detection pulses used to calculate shear wave velocity.

QLAB: QLAB is an onboard quantification program that can also be used on a computer to analyze data. QLAB on the Philips iU22 has the following available plugins: 3DQ, IMT, FHN, MVI, EA, VPQ, and ROI.

QLAB IMT: This iU22 QLAB tool makes measurement of intima-media thickness in carotids and superficial vessels quick and consistent.

QLAB 3DQ GI: This QLAB tool on the Philips iU22 allows viewing, quantification, cropping, rotation, and measurements of 3D image data set.

FHN: Fetal Heart Navigator on the Philips iU22 allows doctors to acquire a fetal heart volume scan in as little as two seconds

QLAB VPQ: Vascular Plaque quantification is an application on the Philips iU22 that uses 3D technology to examine arteries and determine the risk of stroke or cardiovascular disease, measure how much plaque is present, and the percentage of vessel reduction.

QLAB ROI: A plugin within QLAB on the iU22 that uses contrast and 2D imaging to increase the consistency and reliability of acoustic measurements.

EA Elastography Analysis: A QLAB tool on the iU22 for strain-based elastography analysis and decision-making.

QLAB MVI: MicroVascular Imaging on the Philips iU22 maps contrast agent progression, measuring frame-to-frame changes, suppressing background tissue and capturing additional data that make it significantly easier to visualize the vessels.
