The WIT architecture combines novel technology and software enhancements that deliver workflow efficiencies at each stage of the exam.
A 16 or 32 channel RF system with integrated Head and Body/Spine coils can be used individually or in combination with anterior coils for comprehensive neuro and body imaging.
Light-weight coil designs, multiple coil connection ports, and auto element selection all contribute to simplify patient positioning and extended coverage in head-first and feet-first imaging for all scans.
The WIT monitor on the face of the gantry provides patient information and assures gating integrity without repeated trips to the control room.
The technologist can view basic patient information, patient orientation, coil set-up and confirm gating functions are working properly all right at the gantry, reducing the technologist tasks prior to starting the scan.
A key contributor to smooth workflow is Echelon Oval’s WIT Mobile Table - the widest available tabletop in 1.5T. Patients are prepped and comfortably positioned in the exam room as the technologist confirms patient and scan information. Translation…more completed scans done faster.
● 63 cm wide – widest available
● 550 lb. weight capacity
● 20” minimum elevation
● Elevation adjustable when detached
Digital Drive DX provides analog to digital conversion of the RF signal right at the gantry with fiber optic transmission to the equipment room to reduce signal loss and noise pick-up. With the digital conversion in the scan room, the MR signals are isolated from the external noise sources, resulting in the highest possible signal to noise ratio.
Echelon Oval’s Vertex II computer and Origin MR operating software deliver seamless workflow from patient registration through post processing. The Clinical Study Library, Graphical User Interface (GUI), Intelligent Parameter Guidance, and Real-time Image Quality Calculator simplify acquisition planning for even the most complex examinations.
Features: ● Simultaneous scan, reconstruction, and multi-tasked image processing
● HIS/RIS Interoperability
● DICOM and IHE (SWF-PIR) compliant
● Automatic protocol selection
● Intelligent parameter guidance
● Real-time image quality calculator
Echelon Oval delivers the full spectrum of clinical capabilities. Our leadership in imaging techniques such as fat suppression, non-contrast MRA, and motion compensation combined with Hitachi exclusive capabilities ensure diagnostic confidence for even the most challenging patients.
Neurological Capabilities That Matter
Echelon Oval provides the essential acquisition and post processing tools for high-quality imaging of the brain and spine.

Body Capabilities That Matter
Echelon Oval delivers enhancements in dynamic, diffusion weighted, and motion compensated imaging to aid diagnosis in a breadth of applications including liver, kidney, prostate and breast.
● Short breath-hold times with extended coverage for general body imaging with RAPID
● Extensive motion compensation techniques to reduce motion with the All Around RADAR suite of sequences
● TIGRE provides high temporal and spatial resolution with uniform fat suppression for dynamic imaging
● Whole Body DWI for lesion detection
Vascular Capabilities That Matter
Many factors including blood flow dynamics, bolus timing, and large FOV contribute to making vascular and cardiac imaging challenging even for the most experienced facilities. Echelon Oval provides easy to implement features that deliver consistent results head to toe.
● Simplify bolus timed MRA with FLUTE and TRAQ
● Non-contrast MRA solutions, VASC-ASL and VASC-FSE, reduce costs and risk
● Selective saturation MRA delivers controlled area of evaluation for brain and abdominal regions
● Functional morphilogical, perfusion and coronary artery imaging
Echelon Oval’s 1.5T magnet features ultimate stability. Its design includes inherent shielding from magnetic fluctuations, high order active shimming technology (HOAST) applied per patient assuring exceptional magnetic field uniformity, and very low Helium boil off.
