Cardiac Functions

Technology Supporting Routine Cardiac CT Examinations


Automatic Calculation of Imaging and Image Reconstruction Conditions

This is a function*1 that captures the heart rate range during breath-holding practice and automatically calculates the imaging conditions and image reconstruction conditions based on ECG waveform data. The operator can easily check whether the automatically calculated imaging conditions are appropriate or not with the displayed temporal resolution graph. The condition setting modes include auto, semi-auto, and manual, which can be selected according to the purpose.

There is a figure of the setting screen of CardioConductor here.

IntelliEC Cardiac

Modulation Setting of X-ray Radiation Dose

This function allows for an adjustment of the X-ray radiation dose based on ECG information. It reduces radiation exposure in cardiac CT examinations by imaging cardiac phases other than the resting phase of the heart with a lower X-ray dose.
Since the modulation of the tube current can be set up to two phases, it can also be set to match the resting phases of middiastole and end-systole.

There is a graph of tube current and  the X-radiation dose when using IntelliEC here. This graph shows that the amount of tube current is increased when a dose is required, and the amount of tube current is decreased when a dose is not required in response to the diastolic cycle of the heart.
The 3D image of reconstructed cardiac image and 2D image taken using IntelliEC that is the source of the 3D image are shown here.

Automatic Selection of a Cardiac Phase with Less Heart Motion

This function automatically selects a cardiac phase with the least heart motion after cardiac CT imaging. The amount of motion in each cardiac phase was calculated*2 based on the collected data and ECG information, and the cardiac phase with the least motion was selected as the appropriate reconstruction condition. CardioHarmony reduces the time required for finding the appropriate cardiac phase and image reconstruction necessary after cardiac CT imaging.

There is a graph of showing the amount of cardiac movement in each diastolic cycle here.
The 3D cardiac image is here which was reconstructed from 2D using CardioHarmony.
  • *1 Checking setting, and adjustment by the operator required depending on the conditions used.
  • *2 Calculated conditions require checking and adjustment by the operator.

The Next Stage Leading to the Future for All

Eco mode

Reducing Power Consumption during Standby

The On-time Standby function reduces power consumption by up to 47.0% compared to the unused state by controlling units built into the gantry. In addition, the Off-time mode function, which disconnects power while maintaining detector characteristics, reduces standby power consumption by up to 72.7% compared to unused state.

There is an illustration showing the reduction rate of power consumption when using Eco mode here.

Sentinel Customer Support

24 Hours a Day, 365 Days a Year Monitoring by IoT

Our sales, application, maintenance/service personnel, and Sentinel Customer Support, our remote maintenance program, will continue to monitor your CT systems even after installation.
We will provide long-term support to maintain and improve the environment of CT systems by evolving functions on a daily basis, such as monitoring 24 hours a day, 365 days a year through IoT, while detecting signs of failure to prevent them from occurring in advance.

There is an illustration that shows application staff, Sentinel customer support members, maintenance service staff, and sales staff are monitoring your CT system here.
