About the HDI 5000

New Ergonomics

A fully articulating monitor, with an integrated handle, facilitates optimum positioning during exams. Head and eye movements are minimized, and neck and shoulder stress is reduced. Integrated foot and palm rests promote good posture, lessening fatigue and further reducing stress.

The new cart was designed for mobility. It includes additional chassis handles to aid in moving the system – in the imaging lab, down the hall, by the bed – wherever premium ultrasound is needed.

An exciting new feature is iSCAN Intelligent Optimization, which automates many control panel adjustments by the simple push of one button. Adjustments include TGC, receiver gain, compression curve re-mapping, and Doppler PRF and baseline. iSCAN streamlines workflow and frees clinicians to concentrate on exam protocol and patients.

Tissue Harmonic Imaging

Philips/ATL's patented Tissue Harmonic Imaging (THI) enables a dramatic reduction in image artifacts, reduces haze and clutter, and significantly increases contrast resolution. Philips Medical Systems was recently awarded a U.S. patent for Tissue Harmonic Imaging.

With Tissue Harmonic Imaging the fundamental ultrasound signal is transmitted at a broad band of low frequencies. The signal resonates off tissue in the body at twice the transmitted frequency. Because the higher-frequency signal travels one way from the tissue to the transducer, it is not attenuated by round-trip travel through tissue. And, since the signals do not include fundamental frequencies, they are virtually free of artifacts.

Tissue Harmonic Imaging demonstrates significant improvements in grayscale imaging, especially on patients considered to be technically difficult, and provides a new level of patient-independent performance that can salvage examinations initially deemed undiagnostic.

Clinical Benefits

• Provides better visualization of tissue interfaces, especially on technically difficult patients

• Dramatically reduces haze, clutter and image artifacts

• Provides incremental improvements in diagnostic confidence and patient throughput

 Tissue Doppler Imaging

In traditional Doppler imaging, signals from moving tissue are eliminated so that only high frequency signals from the red blood cells are processed. With Tissue Doppler Imaging, the tissue signals are preserved so that suppression of blood flow signals can successfully be achieved by exploiting the difference in signal amplitude between moving red blood cells and moving tissues.

Tissue Doppler Imaging suppresses the low amplitude and high velocity signals. Only high amplitude wall motion signals remain.

Third-generation SonoCT®Imaging with XRES™ Technology

SonoCT Real-time Compound Imaging, which scans and combines up to nine lines of sight in real time, revolutionized ultrasound image quality and allows clinicians to see more than they've ever seen before.

A proprietary ultrasound visualization technology based on algorithms originally developed for Philips MR imaging -- performs real-time analysis of patterns on ultrasound images at the pixel level, making it easier for the human eye to see tissue patterns. This breakthrough processing technique performs 350 million calculations per frame, resulting in a dramatically improved visualization of tissue textures and sharpened margins and borders at real-time frame rates.

The XRES option is available on the HDI 5000 SonoCT system and is supported on an expanded range of HDI broadband transducers. Applications include abdominal, OB/Gyn, breast, small parts, vascular and musculoskeletal. XRES technology supports live and Cineloop® review and as well as Panoramic and 3D imaging as post-processing functions.

Furthermore, SonoCT imaging is now available on our tightly-curved array transducers: the C8-4v and C8-5. Applications include OB/Gyn, pediatric/neonatal abdominal, pediatric and neonatal cephalic, and vascular exams.

Endoscopic ultrasound capability is supported, allowing for imaging of the gastrointestinal wall, biliary and pancreatic ducts and surrounding organs.

Contrast Specific Imaging

• MicroVascular™ Imaging, a processing technique that improves the visualization of contrast in small vessels.
• An extended loop capability allows an entire contrast study up to three minutes to be captured and stored.
• Contrast capability has been added to the P4-1 phased array transducer for deep abdominal exams and to the CT8-4 intraoperative transducer.
• Agent Detection Imaging provides a quick survey tool to detect the presence or absence of contrast agents.
• Power Pulse Inversion, now released for radiology, is a colorized low mechanical index (MI) pulse inversion image overlay on a fundamental grayscale image. And it has been upgraded to include increased sensitivity in low MI real-time Pulse Inversion on several transducers.
