Magnetic resonance imaging system
The Vantage Orian 1.5 Tesla (1.5T) magnetic resonance imaging (MRI) system is a wide-bore magnetic resonance diagnostic device developed by Canon Medical.
The device is designed to produce cross-sectional transaxial, coronal, sagittal and oblique images of the head or body, as well as produce enhanced imaging without contrast such as magnetic resonance angiograms (MRA).
The MRI system received 510(k) certification from the US Food and Drug Administration (FDA) for clinical use in November 2018.
The Vantage Orian 1.5T has a slim and compact design featuring a 1.4m-long light-weight magnet that weighs 3.8t.
The system includes Saturn-gradient technology for high-resolution imaging capability and offers a maximum gradient amplitude of 34mT/m or 45mT/m combined with a maximum slew rate of 155T/m/s or 200T/m/s to obtain improved image quality.
The system has a rise time ranging from 0.220 milliseconds (ms) to 0.225ms.
The PURERF Rx technology used in the system offers adaptive noise cancellation and increases the signal-to-noise ratio (SNR) by up to 38%, further improving the image quality. It includes a 71cm-wide bore patient aperture and an MR Theatre for a virtual immersive experience.
The system also features the Canon Pianissimo™ and Pianissimo Zen technology to reduce scan noise, which makes the MRI environment relaxing and comfortable for patients. The gradient coil and the whole body coil design of the system render maximum field view of 55cmx55cmx50cm.
The MRI includes an optional detachable and dockable table, which enables easy patient handling. The digital gantry interface displays patient and coil information, which enables clinicians to have the full set-up without stepping away from the patient.
The MRI system comes with a range of software enhancements for decreasing the scan time and improving productivity. The Multiband SPEEDER helps clinicians decrease the diffusion-weighted imaging (DWI) acquisition times.
The k-t SPEEDER (up to eight times accelerated) provides perfusion imaging at high frame rates, enabling patients to breathe freely.
The quick scanning speeds of the MRI system are further enhanced with a new Fast 3D mode. The new Rapid Scan and EasyTech technology range minimises scan time and improves workflow.
The EasyTech technology allows automatic scan planning with alignment and positioning for examining spinal cord, heart and nerves. The WFS Dixon (FSE2D) captures four contrasts in one scan and allows uniform suppression of fat and homogeneity in difficult-to-shim areas.
Quick Star and 2D Real-time motion correction (RMC) are few enhancements of the MRI system to reduce inaccuracy or other imaging issues due to body movements.
The new Vantage Orian 1.5T MRI system improves productivity, while its low-power consumption feature reduces running costs.
The standard scan planning tool ForeSee View enables radiographers to plan for accurate image capturing procedures. This feature will be useful to image anatomies of the organs and areas that are difficult to plan such as the heart, pancreas and joints.
