The HI VISION 8500 system has a new feature called SonoElastography which is able to acquire tissue elasticity data through the use of freehand compression while a scan is going on.
Medison introduced new additions to its mid-range Sonoace 8000 live. One big addition to the system is the migration onto the system of the company's 3D Extended Imaging (3D XI) technology, which offers diagnostic ultrasound image processing. 3D XI is designed to bring CT and MRI-like imaging to ultrasound diagnosis.
Medison also showcased a new cardiovascular edition of the SonoAce Special Edition (SE). The mid-class ultrasound system has been outfitted with new processing technology, as well as CW (Continuous Wave) Doppler imaging and pulse inversion harmonic imaging.
Mindray showcased its DP-9900Plus Digital Ultrasonic Diagnostic Imaging System which puts to use the company's all-digital ultrasound technology. The system joins ultra broad-band, multi-frequency technology with an ergonomic engineering design.
Philips Medical Systems showcased its iU22 Intelligent Ultrasound System which now includes new cardiology capabilities such as Live 3D Echo and 3D/4D abdominal image quality, on- and off-cart upgrades to QLAB Quantification Software, and a new L9-3 transducer. SonoCT with XRES technology is part of the iU22 system for 3D, 4D and MPR imaging which allows for such new applications as real-time 4D imaging of the fetal heart.
Another system, the HD11 XE, is a multi-specialty system which is capable of spatial-temporal image correlation; iSCAN Intelligent Optimization technology; Region of Interest (ROI) quantification; Strain Quantification; and interchangeable transducers.
Also highlighted was the HD3 which is a more basic model geared for general office exams.
Siemens Medical Solutions highlighted upgrades to its Sequoia system that include a new high-resolution, flat-panel monitor, ergonomic features which make the system more easily transportable, a memory stick device for patient data transport, and a DVD burner for image storage.
The Encompass II release features high-resolution color flow (HRCF), a technology that applies Chirp-coded excitation to color Doppler to dramatically address spatial resolution and sensitivity.
Siemens also showcased advances such as its Cadence contrast pulse sequencing (CPS) technology for improved contrast detection and specificity for molecular imaging with ultrasound.
SonoSite Inc. emphasized the new capabilities of its MicroMaxx hand-carried ultrasound at RSNA. New features of the MicroMaxx include:
- Two new broadband transducers, the P10/8-4, a high-frequency, phased-array probe for pediatric and neonatal radiology, and the SLA/13-6, a high-frequency linear array;
- SonoRES for speckle reduction;
- Transcranial Doppler; and
- Wireless capabilities.
TeraRecon Inc. highlighted its partnership with Fukuda Denshi Co. Ltd. through which the companies introduced a cart-based cardiovascular ultrasound scanner - the Imagic Sigma 5000 series.
Terason showcased its newly launched t3000 and t2000 ultrasound systems.
The Terason t3000 system is based upon Teratech Architecture that combines the front-end Fusion Processor with PC-based back-end data processing. They can be quickly converted from a portable unit to a cart-based system.
The t2000 includes SmartProbe which allows standard laptop computers to provide high-quality diagnostic images usually associated with larger systems.
Also shown was the Echo Ultrasound System with front-end Fusion processor with powerful PC-based back-end data processing.
Toshiba America Medical Systems Inc. demonstrated the newest features for its Aplio and Xario systems. The company has expanded the Differential Tissue Harmonic Imaging (DTHI) capabilities for the Aplio XV premium edition for use with difficult to scan patients; and introduced 4D imaging for the lower priced Xario.
Each of the systems includes the ability to save native data captured during an exam to allow for "virtual rescans."
Ultrasonix Medical Corp. previewed its Sonix Live ultrasound video streaming technology in conjunction with the company's Sonix SP ultrasound system.
