About the HDI 3000

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.

Raising the standard for diagnostic ultrasound excellence

The HDI provides the next step in diagnostic performance across all imaging modes. Greater contrast resolution and more anatomical detail, plus enhanced spectral and color Doppler sensitivity, provide additional diagnostic information.

The new Color Power Angio, ATL’s next generation of Doppler Power Imaging, delivers sensitivity and resolution – with no apparent flash artifact. 

Tissue Specific Imaging – A New Approach to Ultrasound Image Optimization

Simply choose a target application when selecting a scanhead – the rest is automatic. The entire system is automatically optimized for each exam to improve productivity and quality, enabling all users to attain a higher level of performance.

Complete Clinical Capabilities

The new HDI system provides abdominal, obstetrics, gynecology, vascular, small parts, cardiac*, breast, prostate, and transcranical imaging.

HDI technology continues to expand the clinical utility of ultrasound. The new Entos CL10-5 intraoperative Vascular Scanhead brings the benefits of HDI broadband imaging to the operating room. Its innovative shape and excellent near-field resolution allow unprecedented incision site access and visualization of anatomy and pathology.
