  5. ・High Performance Magnet ・Ultra-high Sensitivity HighPerformance ・High Power Gradient Responds to the needs required for high magnetic field system. ・High Speed / Advanced Technology Advantageous points with VOSI technology are…. (when compared with horizontal-field) 1.High sensitivity due to solenoid QD coil S/N : + 30% (Approx.) 2.Low noise amplifier (lower frequency, higher advantage) S/N : + 20% (Approx.) 3.Narrow band receiving circuit (with less chemical shift) S/N : + 20% (Approx.) 4.In addition, use of tight receiving coil improved filling factor (filling rate) largely, and realized further high sensitivity. As result of all above, receiving sensitivity of vertical magnetic field system is, 1.3 x 1.2 x 1.2 ≒1.9 This is approx.1.9 times higher than that of horizontal magnetic field system. Therefore, with APERTO 0.4(T) x 1.9 = 0.76 Image quality better than that of 0.76T can be obtained. “VOSI” technology Hitachi is proud of. Vertical-Field with Optimized Sub-System Integration Technology Since MRI is composed of many sub-systems, optimum integration is the key point for high image quality. Field strength is merely an element． Solenoid QD coilS/N:1.3 High frequency amplifier Receiving circuit Amplification S/N: 1.2 Band S/N: 1.2 Amplification S/N: 1.0 Band S/N: 1.0 Saddle QD coil Use of tight coils APERTO X 1.9 0.4 0.76 1.0T system Filling factor S/N:1.0 ~ 1.0 0.5 A different solution to the high field
