Low Dose (Low Dose Solution of X-ray [Digital Imaging])

Digital Imaging

Advanced Image Processing (AIP)

It has been almost a century since Toshiba Medical began its research and development for the first X-ray tube in Japan.
Advanced Image Processing (AIP) is the latest image processing methods based on the image processing technologies that have been developed by Toshiba Medical over many years. Toshiba Medical's original technologies have led to significant advances in imaging equipments.

The Super Noise Reduction Filter (SNRF), Toshiba Medical's proprietary technology, which has been developed based on a thorough reevaluation of conventional X-ray control and digital image processing. With the SNRF, the desired signals and unwanted noise are calculated in real time in order to extract the signals for each image pixel.
There is no need to increase the X-ray dose in order to reduce noise or to employ noise-reduction techniques such as a temporal filter (recursive filter) or frequency conversion. The FPD can provide extremely sharp, high-quality fluoroscopic/radiographic images in real-time.

Fluoroscopic image acquisition

The enhanced fluoroscopic images provided by SNRF allow the clinician to avoid unnecessary cine (DA) exposure.
The clinician can choose fluoroscopic acquisition in the same manner as DA acquisition, allowing the patient X-ray dose to be reduced.

The SNRF provides significant horse reduction while maintaining high temporal resolution.

Unique fluoroscopic image recording procedures

Various recording modes are available for high-quality fluoroscopic images acquired with the SNRF.
These acquisition techniques can be operated simply by pressing the footswitch. The clinician can choose fluoroscopic acquisition in the same manner as DA acquisition, allowing the patient X-ray dose to be reduced.

F-REC

Fluoroscopic images acquired after pressing the fluoroscopy start button are recorded. Images can be recorded for up to 90 seconds or 1020 frames. (Dynamic image recording)
F-STORE

Fluoroscopic images acquired in the last 60 seconds (max.) are recorded. Press the F-STORE button after fluoroscopy is completed to save the run as part of the patient file. (Dynamic image recording)
F-REC(S)
The LIH (last image hold) image acquired in fluoroscopy is recorded.

Significant contribution to minimizing dose

The graph on the right compares the cumulative air kerma measured for cardiac catheterization procedures with and without SNRF as measured on over 400 clinical cases.
The fluoroscopy/radiography frame rate (fps) and fluoroscopy time were similar, but the result shows a significant decrease in the cumulative dose.
SNRF combined with simple fluoroscopic recording techniques have been proven effective and have reduced cumulative procedure dose by more than 50%.

Average cumulative procedure dose

Low rate pulsed fluoroscopy

The noise less and less lag image provided by SNRF allows clinicians to work with lower pulsed rate fluoroscopy, while contributes to reduce total case dose.

Virtual collimation and filtration

After fluoroscopy, virtual collimation uses software to simulate collimator and beam filter positions. This allows the operator to adjust collimation without additional fluoroscopy, further reducing the X-ray dose.
