15 Superb image quality prime FSE * primefse optimizes the echo allocation and minimizes Inter Echo Time in FSE sequences. These features help reduce artifact and acquire easy-todiagnose images. Also, the flexibility of parameters simplifies the parameter settings.

16 High definition MRA cerebral aneurysm * Option MIP image VR image FITT (Fine tune technology) FITT compensates gap in signals between slabs. This feature enables improved image quality in MRA by optimizing MTC pulse and RF pulse. FITT realizes clear images of fine vessels without boundary artifact between slabs. VR* (Volume Rendering) VR* helps understand anteroposterior relations. Since this rendering process is done on the MRI console but not the 2 nd workstation, examination can be conducted efficiently.

17 FatSep Separate images of fat and water can be obtained in a wide FOV. Benefit: Applicable to various applications without limitation of FOV. The open gantry allows special patient positioning (like above picture) which is difficult with Closed MR is possible.

18 CHESS (RF fat saturation) CHESS fat suppression method * CHESS* was thought to be difficult to be realized with Open-MRI. However, high homogeneity is secured by Super Shim* which enables CHESS*. CHESS:off CHESS:on Benefit: Fat suppression with various sequences including FSE, FIR, BASG and DW-EPI. High order shimming * Super Shim* enables high order shimming to compensate complex cause of inhomogeneity of the magnetic field. Benefit: Homogenized magnetic field even with a patient inside the gantry.

28 Soft Sound feature Excellent patient experience in MR exam Quieter acoustic noise Small gradient vibration Secrets of less audible noise and vibration feature No resonant parts to amplify acoustic noise The Flat GC does not vibrate much due to its shape Gradient coils In case of APERTO Lucent, the gradient vibration hit the GC from the side. Thus, the GC does not vibrate much. Copyright Hitachi Medical Corporation All rights reserved. 27

29 Amenity of patient table Minimum height The minimum table height of about 450mm enables the elderly patients and small children to get on and off the table easily. Foot switch For vertical and horizontal movements of the table Benefit: Hands of the operator remain free for taking closer care of patients.

30 Economical and ecological Small running cost No need to purchase expensive periodic replacement parts and supplies. Stable operation is assured with no risk of quench. Electrical power saving Since the required power supply is only 10kVA and a large-scale cubicle is not required, the monthly cost of electricity is very reasonable. Small installation space Since the equipment room is not necessary, the installation space can be used efficiently. Also, the small shield room helps save the cost for ancillary equipments. Actual installation plan may vary depending on the condition of the site. Copyright Hitachi Medical Corporation All rights reserved. 29
