Taking the Definition one step further, at last year's RSNA Siemens introduced the first six syngo® Dual-Energy applications. These applications showed how users can generate more relevant clinical information by leveraging the Definition's innovative dual-source design. Scanning with two X-ray tubes operating at two different voltages simultaneously can produce CT images that were never before possible. Siemens will continue to show data generated by innovative, new combinations of varying X-ray tube voltages and will also showcase new enhancements for its single-detector, single-source CT products.

Hitachi
Hitachi's 1.5 T MRI called the Echelon is a linchpin of the company's display and incorporates a processing engine called Vertex. Software that takes advantage of the current architecture is blended with new features that enhances the company's radial imaging capacity. New features include time resolved MRA and RADAR, radial imaging capability. Also on display, the Altaire High Performance Open MR that includes single shot EPI, diffusion weighted EPI and RF fat saturation. In keeping with the company's open architecture, Hitachi's Airis Elite Advanced Mid Field Open MR incorporates multichannel active shimming, a scalable DualQuad RF receiver and other advanced capabilities.



Varian
Known for its cancer treatment technologies and X-Ray products, Varian has a number of new and upgraded PaxScan digital X-Ray imaging technologies on display. These include the PaxScan 1313, the PaxScan 2520V, for cardiac and C-arms and the PaxScan 4030CB, which includes the company's second generation command processor. It is used for cone beam CT, acquiring high resolution fluoroscopic images at up to 30 frames per second and radiographic images at up to 7.5 frames per second. PaxScan flat-panels are available in a variety of sizes and configurations and have been incorporated into systems for orthopedic, gastrointestinal, dental, veterinary, radiographic, fluoroscopic, and cone-beam CT (volumetric) imaging.

Medrad
In CT, the company plans to talk about enhancements to its Stellant D CT injection system. The technology will automatically prescribe injection protocols by factoring in such specifics as a patient's body weight, contrast concentration and scan duration. Called SmartFlow, the system offers a host of other options, all designed to improve results and efficiency. For MRI, Medrad's 3T Prostate eCoil is matched with GE's Signa3T MR scanners and is designed to produce accurate images of the prostate, leading the way to efficiently targeted radiation therapy. Generally, the anticipated results are a narrowly specific view, high spatial resolution and sensitivity.
