HITACHI: HI VISION Preirus

HI VISION™ Preirus™ is the next generation premium ultrasound system from Hitachi, packaging all the features and capabilities you’ll need into one complete, compact, and portable system – perfect for any imaging environment.

Hitachi’s UltraBE enables unprecedented image detail through seamless coordination of all functions along the data chain from digital beamforming to signal processing. This close synergy ensures the advanced software of Preirus uses the strongest, cleanest signal to create the highest quality images.

Workflow Efficiency Tools

HI VISION Preirus incorporates a powerful set of standard and unique features that reduce repetitive tasks and enhance diagnostic confidence so you can decrease overall examination time.

PDC

Patient Dependent Correction (PDC) from Preirus allows you to make adjustments to the assumed speed of sound in soft tissue. By adjusting the PDC setting, users can optimize images based on patient-specific characteristics, like the prevalence of adipose tissue, for increased clarity and resolution

Real-time Tissue Elastography (E-mode)

First commercialized by Hitachi, E-mode gives you new information to use in the characterization of tissue in a wide range of clinical applications. It quickly and easily creates detailed color maps of the relative stiffness of tissue using a range of standard linear convex and endocavity probes.

Real-time Virtual Sonography (RVS)

RVS merges live ultrasound with images from a different modality, allowing users to enjoy the advantages of both. Once a previously acquired MRI, CT or Ultrasound volume dataset is loaded into Preirus, its positional sensor recognizes the orientation and position of the ultrasound probe and uses that information to reconstruct a slice that corresponds with the ultrasound image. The result is a side-by-side display of the live ultrasound image with a “virtual” live MR, CT or Ultrasound image.

Beam-steered Biopsy

Preirus comes standard with Beam-steered Biopsy Guidance, a proprietary Hitachi technology that directs compound lines of sight towards a biopsy needle for clear visualization of its position during any ultrasound guided biopsy or ablative procedure.

HI Definition Tissue Harmonic Imaging (HdTHI)

Hitachi’s advanced pulse inversion harmonics technique, HdTHI, uses expanded fundamental frequency bandwidths to increase the harmonic bandwidths as well. The resulting signal includes a broad sample of signals across the probe’s bandwidth, including the sub-harmonic frequencies ignored by other methods. This gives the system flexibility to employ higher frequencies when creating the nearfield portion of an image and lower frequencies in the farfield portion.

Ergonomics

Real-time Biplane Imaging

RTBi simultaneously displays two real-time ultrasound images from two separate transducers. The imaging parameters of each transducer (including gain, depth, focal position, tissue harmonics and dynamic range) can be adjusted independently.

By providing image guidance from two different scan planes, RTBi can improve the accuracy of needle placement and the monitoring of interventional procedures including cryotherapy where the additional probe allows visualization of the distal border of an ice-ball as it forms.

Volume Imaging

Using one of Hitachi’s curved, linear or endocavity volumetric probes, Preirus can quickly and precisely obtain volume data. Once acquired, Hitachi’s powerful software can present the data as you like it: as a volume rendering, maximum or minimum intensity projections, or in a series of slices like MRI or CT images.

Coded B-mode

Hitachi’s powerful Coded B-Mode feature allows deeper penetration without reducing fundamental frequency and compromising spatial resolution.

The unique dual encode/decode process also greatly reduces noise resulting in high resolution, high contrast B-mode images even when extra penetration is required.
