Diagnosis Benefit 01 Open De sign and ORIGIN Software Ease of use for op erators, friendly to patients Wide Opening The wide open gantry of AIRIS Light MSK offers patients a calm scanning atmosphere. The beautiful system design focuses on high patient comfort and is the result of Hitachi's relentless patient-centric dedication. Patient-Centric Design AIRIS Light MSK's innovative design allows patients to be accompanied by a friend or relative during scanning to help them feel at ease, extending MRI imaging opportunities in the anxious patient. Curved MPR Arbitrary curved slices can be effortlessly reconstructed from 3D image data. This technology allows simultaneous reconstruction along multiple curves, especially useful in the event of scoliosis. Radial MPR MPR images of radially positioned slice planes are easily created, facilitating diagnosis in complex structures such as knee joints. AIRIS Light MSK : 04-05 Wrist (Distal radius fracture ) Off-center region imaging Elbow (Osteochondritis dissecans ) Laterally Aligned Table The adoption of AIRIS Light MSK's laterally aligned table results in a combination of compact footprint and ease of use. The free-floating table top enables quick positioning of the target region to the centre of the magnetic field, to provide high-quality iso-centric imaging. In addition, the wide range of lateral table movement allows easy positioning of peripheral anatomy, such as the shoulder or knee, at the centre of the magnetic field.
Examination Benefit 02 Advanced Technologies Image Quality that meets the needs of today's MRI challenges High Resolution Imaging For AIRIS Light MSK, Hitachi has developed an image reconstruction matrix of 2048 x 2048 providing high-definition imaging and clinical solutions to maximise diagnostic confidence. Linear shimming method High order shimming method SuperShim Uniformity of the static magnetic field is a crucial requirement in MRI. Super Shim is equipped with both a linear and high order shimming function. This feature is able to correct for static magnetic field inhomogeneity which is impossible to correct adequately by means of linear shimming alone. RADAR T1WI RADAR T2WI RADAR* (Motion Artefact Reduction Function) Motion artefacts can cause serious problems during MR imaging. RADAR based on a radial scan technology supports the reduction of motion artefacts. The advantage of this function is versatility. It is applicable to any imaging plane as well as various pulse sequences, such as T2 and T1 weighted images. It is particularly effective for imaging the shoulder joints, usually significantly influenced by respiratory motion. Magnetic field direction FatSat* ( CHESS, an advanced fat suppresion method) Combined with SuperShim, AIRIS Light MSK provides CHESS fat suppression method even in a low field MRI system. It is applicable with various sequences including FSE, FIR and BASG. Permanent magnet Solenoid type receiver coil Pole piece [Solenoid type receiver coil intensity distribution] Sensitivity High Low High-Sensitivity Solenoid Receiver Coils AIRIS Light MSK uses a vertical magnetic field and solenoid receiver coils. These coils are approximately 40% more sensitive than the receiver coils of horizontal magnetic field systems. They provide a wide FOV craniocaudally. AIRIS A I R Light I S L i g MSK h t M S : K 06-07 : 0 6-0 7 FatSep ( Fat-Water Separation method) FatSep is a method that suppresses fat signals using differences of proton resonance frequency between water and fat. FatSep, less influenced by inhomogeneity of magnetic fields, enables fat suppression in a wide range of body regions. Gradient magnetic field strength Ideal characteristics Precision deterioration Response deterioration Conductive pole piece Magnetic circuit Time Eddy current Gradient magnetic field strength Ideal characteristics Response improvement Pole piece Magnetic circuit Time ECC (Eddy Current Control) Advanced Gradient Coil System Suppressing eddy currents in the gradient coil system is key to providing stable high quality images. Eddy currents can cause deformation of the gradient magnetic field waveform which results in a direct deterioration of image quality. Hitachi not only uses materials that have low eddy current susceptibility but has also developed the ECC (Eddy Current Control) feature that predicts and controls eddy current generation. *Optional

Management Benefit 03 Performa nce, Profitability, Reliability Our answer to toda y's radiology challenges Customer's site Conceptual diagram of Sentinel Sentinel serve system Firewall Internet Firewall Occurence of abnormality Hitachi service staff Automatic e-mail notification Cumulative Running Cost for 5 years (Electricity Expense by the System Only) System status screen 1st year AIRIS Light MSK 2nd year 3rd year 4th year 5th year Hitachi Superconductive MRI The graph ist for illustration purpose only. It depends on the system specification and operational status. Profitability Since AIRIS Light MSK is designed to run on a single phase power supply, initial investment can be kept to a minimum. In addition, low electricity consumption keeps monthly running costs very affordable. Sentinel* Customer Support for AIRIS Light MSK AIRIS Light MSK is compatible with Hitachis's customer support system, Sentinel*. Sentinel is a system which monitors the operational status of your MRI to support stable and efficient use. AIRIS Light MSK is able to capture information about its operational status, which is subsequently sent to and archived in the Sentinel server at Hitachi. At the time that an abnormality is detected, a notifying e-mail is sent to the service staff to prompt appropriate action. The long-term operational status can be confirmed using accumulated information organized in a chronological manner. Users are required to set up their network environment to make it compatible with Sentinel. The contents of the service may vary depending on the content of contractual coverage. Siting Flexibility AIRIS Light MSK : 10-11 AIRIS Light MSK has very limited stray fields meaning that scan rooms can be kept small. It does not require an equipment room, a chillier unit or other equipment associated with superconductive MRI installations. Consequently, AIRIS Light MSK can fit into the confined spaces found in most medical facilities. AIRIS Light MSK Layout (Example) 0.5mT
