At Philips, we have taken full advantage of digital circuitry and the freedom it provides from issues involving drift, component tolerance, and calibration. Reliability, flexibility and upgradability are inherent in digital systems, as well as the preservation of diagnostic information fully and precisely without loss, distortion, or degradation.
Broadband beamforming uses the full range of ultrasound frequencies to capture the entire tissue signature information, preserving the quantity and quality of data through capture and preservation of the entire bandwidth of ultrasound signals. Advanced broadband digital beamforming has the ability to correctly steer and focus ultrasound signals containing very broad frequency bandwidths, totally controlling the duration and frequency of each individual pulse. Broadband beamforming improves contrast resolution by acquiring maximum tissue information, and has the ability to differentiate or resolve structures in the depth domain.
Digital broadband beamforming produces the broadest possible bandwidth by applying short pulses for absolute maximum axial resolution. Additionally, digital broadband beamforming allows the application of advanced digital signal processing techniques that further refine and process the bandwidth to adapt to a variety of patient types and resolution requirements. With the platform’s supercomputing power, billions of operations are performed each second, and all of the pure, digital broadband information is processed instantly and displayed in real time.
| The result is images with improved axial, spatial and contrast resolution; highly detailed, ultrafine portrayal of tissue textures; tissue uniformity throughout the entire depth of field; and clearly defined tissue interfaces and structural detail. |

Broadband beamforming transmits a broad signal range and has the ability to capture and process the entire broad band of returning signals.
Philips’ powerful xSTREAM architecture provides the most advanced data acquisition and processing ever applied to ultrasound. Designed around a distributed multi-processor environment and high performance software, this architecture achieves an extraordinary 250 billion operations per second.
Fully flexible, scaleable and software configurable, Philips xSTREAM architecture sets new levels of clinical performance for structural, functional and volume imaging applications.
Structural imaging forms the foundation of any ultrasound system. The
iE33 xMATRIX and
iU22 xMATRIX systems employ a host of proprietary technologies to elevate the visualization of anatomical details to new levels, such as
SonoCT,
XRES, Adaptive Dynamic Range, Pulse Coding, Pulse Shaping and Multivariate Tissue Harmonic Imaging technologies.
Functional imaging modes are important tools that provide physiological data to refine and clarify diagnostic information. The xSTREAM architecture achieves new levels of functional information by employing exclusive next generation technologies, such as Adaptive Broadband Flow Imaging and High Resolution Spectral FFT for superb Doppler sensitivity, and contrast imaging.
Volume and Live 3D imaging relies on the system’s xSTREAM architecture to process multiple data streams simultaneously allowing instantaneous voxel and ray cast rendering of ultrasound volumes whether it be from a freehand acquisition, a mechanically steered array or our revolutionary
xMATRIX array.
