“Interventional procedures involve a series of dilemmas.
The most critical of these dilemmas requires using the lowest-dose mode possible without jeopardizing image quality.
In some cases, it could actually increase total dose if it requires multiple image acquisitions. Is there any other way to reduce the dose for patients?”
*ALARA: As Low As Reasonably Achievable
The use of AI (deep learning) technology has enabled the successful achievement of both noise suppression and enhanced device Visibility of fluoroscopy images. Operators can clearly see what they want to see while achieving lower dose levels.

Unnecessary repeat acquisitions are reduced as low as possible using unique applications to help compensate for devices that are difficult to visualize, movement of the beating heart or from breathing, and patient body movement. Improved imaging helps shorten procedure times and reduces stress and dose levels for medical workers and patients.

The system presents the cumulative dose values for each X-ray exposure area and notifies operators of the total dose applied during each examination. Providing total dose values calculated based on the trends of similar procedures can further increase awareness about minimizing dose levels during procedures.
Read More‘SCORE Opera‘ applies AI (deep learning technology) filter technology to enable efficient noise suppression and contrast enhancement, and improve the visibility of devices that are generally difficult to achieve under low dose conditions. In addition to reducing radiation exposure, the burden of image diagnosis by physicians will be reduced, shortening treatment time.
SCORE Opera has succeeded in reducing the fluoroscopic dose by up to 40% or more*.
In order to further promote accurate treatment in the low dose range, it is equipped with ‘SMART Control’ which provides two user interfaces that control the balance between visibility and dose level in real-time, while supporting fine-control of device visibility according to the treatment scene.
(*Comparison with our conventional system under standard dose ratio [Air Kerma] at 7.5pps and 10pps. )
Advanced PCI support application that makes full use of real-time image processing. By enhancing and fixing the stent in real-time from the dynamic image with heartbeat, it provides more reliable and accurate placement of the stent.
In situations where it is difficult to identify the stent, SCORE StentView offers a unique function that increases stent detection, reducing unnecessary exposure due to re-acquisition.
Based on the real-time image processing technology cultivated in SCORE Stent View, noise on the image is greatly reduced by performing sequential processing. It can be used to evaluate the stent condition after placement.
The enhancement process is viewed on the live monitor during processing, and the user can stop image acquisition when the desired enhancement level has been reached.
It automatically corrects misregistration in real-time. In addition to traditional linear corrections in the x and y axis, it also supports non-linear corrections in the z plane to correct for more complex patient movements. Better visibility of the blood vessels can be acquired in real-time, eliminating the additional manual pixel shifting and shortening the procedure time.
SCORE RSM is a mask-free DSA that Shimadzu succeeded in developing first in the market. It is most beneficial for patients who have difficulty holding their breath.
The power of SCORE RSM can be combined with new applications such as bolus tracking of the entire lower limbs or interlocking with C-arm movement, to increase the performance of other features.
SCORE Chase automatically generates a long view image of the leg by tracking contrast media while the user is freely panning the table in either the longitudinal or transverse directions. The long view image is displayed on the monitor instantly after acquisition, allowing the entire blood vessel to be evaluated quickly and easily. Used together with SCORE RSM, it enables the user to collect long view images with high blood vessel visibility even with patient movement.
The ability to acquire C-arm CT in both the left and right side positions of both the floor-mounted and ceiling-mounted C-arm.
Side acquisition C-arm CT can be performed during normal clinical use with our typical the room size and layout. We support safe treatment in real time with the image guidance required for IVR.
The condition of blood flow is displayed as a color map from the acquired DSA image. By specifying the region of interest that includes the treated blood vessel, it is possible to calculate and compare parameters related to blood flow before and after treatment in that region.
Intuitive color maps and graphs, as well as numerical values, provide a visual and easy-to-understand therapeutic evaluation.
For complex treatments, procedures can be longer, producing higher total dose.
An alert function will notify you when the dose threshold is reached so that the target dose will not be exceeded. Having a notification alert, allows the user to concentrate on treatment without routinely watching the cumulative dose.
Dose eye Live is a dose map application that displays the maximum local entrance surface dose in real time during the procedure. The maximum dose is displayed in a color map, making it easy to see if there are dose hotspots during the procedure.
The dose map considers the C-arm angle, so it is possible to intuitively select a working angle that avoids the high concentration dose area.
Dose reports can be output in CSV format. This allows for detailed analysis and dose management such as dose per protocol and C-arm angle.
A dose ratio pie chart by protocol that was frequently used in the past procedure is displayed. Furthermore, total dose simulations using the recommended pulse rate are also calculated, which leads to awareness of total dose reduction
This is a recording application that saves and outputs live images as video files.
Since all fluoroscopy and exposure images can be reviewed along with the flow of treatment, recording data can be used as educational materials to learn the minimally invasive procedure.
