SCENARIA^TM View

After image acquisition, CardioHarmony automatically*² selects the phase of the cardiac cycle possessing the minimal amount of cardiac movement as the optimal cardiac phase. Search times for the optimal cardiac phases, which is a bottleneck in the workflow of cardiac CT, can, therefore, be significantly shortened.

• *2 The automatic selection must be checked and may be adjusted, if necessary, by the operator.

In this example, the heart rate changed from 37 to 72 bpm during scanning, which makes it difficult to find the stationary phase. The optimal cardiac phase can be found easily by using CardioHarmony.

• * Images and processing are performed on the SCENARIA CT system.

The tube current modulation can be set for up to 2 phases and, in doing so, it is possible to reduce the dose in cardiac CT examinations.

Since the patient table moves up to 200mm laterally, operator can position the Region Of Interest (ROI) close to the center of the scan field without touching the patient. If the region of interest is offset from center of the scan field, then a post recon is required to align to the reconstruction center. However, by using IntelliCenter, this process can be skipped*³ and, as a result, the examination time is expected to shorten*⁴. In general, it is expected to improve the spatial resolution of the image by setting the scan area at the center of rotation. The integration of table lateral movement and tilt scanning also allow more flexibility in head examination. CTDIVol is reduced by a minimum of 8.0%*⁵ when the head is shifted near the center of rotation and the dose compensation filter is switched from standard to small.

• *3 Limited to cases where the scan area can be positioned at the center of the FOV by lateral movement.
• *4 The time starting from the patient lying on the table, until the end of the scan.
• *5 Scan parameters: Tube voltage 120kV, Tube current 300mA, Scanning time 1.0ｓ, 0.625mm×32rows

• Dual Energy Scan
• Shuttle Scan
• Calcium Scoring
• guideShot

• fatPointer(Body fat analysis)

Using the DICOM standard, it is possible to transfer dose information as a DICOM Structured Report (DICOM SR) to PACS etc.

Dose information can be transferred to PACS etc. as a secondary capture image.

The entire system comprises just three components*⁶; gantry, patient table and operator console. No additional units, such as system transformers, are required, so the space in the CT room can be maximized for clinical use.

• *6 For power supply voltage 380/400V
