SCENARIA VIEW

Advanced Features

Optimized Positioning

LATERAL SHIFT TABLE, ± 10CM

IntelliCenter Auto-Lateral Shift Table is the only standard table that can shift up to ± 10cm laterally (20cm total range) to:

• Assist patient positioning
• Reduce dose*
• Improve spatial resolution

MULTI-BOWTIE FILTERS

Multi-Bowtie filter size selection, based on anatomy to be imaged, reduces radiation dose* in areas outside the filter’s field of view. When used together with the auto lateral shift table, off-center anatomy can be brought to iso-center and the smallest bow-tie filter utilized.

Patient Comfort

HIGHER DATA SAMPLING RATE

SCENARIA View's higher data sampling rate provides faster anatomic coverage without sacrificing image quality and reduces motion artifacts.

WIDE 80CM GANTRY APERTURE

A more open 80cm gantry aperture spaciously accommodates the most challenging patients.

550 LBS. TABLE WEIGHT CAPACITY

Higher standard weight capacity to accommodate larger patients up to 250 kg (550 lbs.).

Lower Dose* Techniques

IPV – Iterative Reconstruction

IPV is Hitachi’s Next-generation “vision modeled” iterative processing that provides dose reduction and overcomes a conventional IR weakness by IPV maintaining normal image texture that better matches the image texture appearance of Filtered Back Projection (FBP).

Utilizing IPV vs. conventional FBP reconstruction can provide*:

• Dose reduction up to 83% at the same image quality (low contrast detectability)
• Image noise reduction up to 90% at the same dose
• Noise reduction rate control according to the IPV level used
• Low contrast detectability improvement by up to 2.0X (100%) at the same dose
• Natural image texture appearance (the shape of noise power spectrum) similar to that of FBP, even if using higher IPV strength level

INTELLI EC PLUS

Hitachi’s proprietary 3D mA modulation technology, Intelli EC, automatically modulates mA to lower individual patient dose levels depending on patient anatomy and size and considering the level of iterative reconstruction selected. Intelli EC Plus can be set to provide real-time control of mA, to achieve a constant Noise Standard-Deviation in the resulting images.

HIGHER DATA SAMPLING RATE 

SCENARIA View's higher data sampling rate provides faster anatomic coverage without sacrificing image quality and reduces motion artifacts.

REDUCED kV

Four settings support lower kV and dose based on individual patient size.

Lower kV provides lower dose for small and pediatric patients.

• 80kV
• 100kV
• 120kV
• 140kV

REDUCED DOSE FOR CARDIAC CTA

ECG Dose Modulation reduces mA during the cardiac phases of a retrospectively gated exam that are not intended for image reconstruction.

AXIAL SNAP-SHOT IMAGING

Pulses the X-ray “on” only during a phase of the cardiac cycle using prospectively gated step-and-shoot cardiac scanning – reducing radiation dose.

DOSE REPORTING AND AWARENESS

SCENARIA View provides both DICOM Dose Structured Report and a Simple Dose Report to satisfy the full range of your IT and physician reading dose reporting needs. And, SCENARIA View includes Dose Check, compliant with NEMA XR-25, to monitor for exam doses that may exceed notice or alert levels.

^{*In clinical practice, the use of Intelli IPV may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. Image noise is defined as the standard deviation of pixel values within an area. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. Low contrast detectability (LCD) and/or image noise were assessed using reference factory protocols comparing Intelli IPV and FBP. The LCD measured in 0.625 mm slices and tested using the MITA CT IQ Phantom (CCT189, The Phantom Laboratory), using model observer method.}
