Automatic Exposure Control – significant dose savings at constant image quality with five parameters
Corresponding to this video please find here the recently published study “Evaluation of automatic dose rate control for flat panel imaging using a spatial frequency domain figure of merit”

Reducing dose in interventional procedures is increasingly important for both patients and clinical staff. In many cases, however, image quality is the key to successful procedures.

CARE+CLEAR our comprehensive portfolio of image-quality and dose-saving tools, supports you in making confident decisions in diagnosis and treatment and increases the safety of both your patients and staff.

A Siemens exclusive: CARE+CLEAR is standard with every Artis angiography system. Unmatched since 1994.


Low-dose imaging is becoming a clinical reality

Dose reduction

CARE
As a leader in healthcare innovation, Siemens has a strong legacy in dose-reducing technologies. For many years we have been focused on reducing dose without compromising image quality and clinical outcomes. The philosophy behind our Combined Applications to Reduce Exposure (CARE) is simple: They are designed to help you deliver better care at the lowest reasonable dose.

CARE Benefits

  • Reduces patient and operator dose to a minimum
  • Provides dose monitoring during the procedure
  • Makes dose reporting easy and structured
  • The complete CARE package is standard with every Artis system
CAREposition
Based on the Last Image Hold (LIH), a graphical outline of the upcoming image is displayed on the monitor, allowing you to move the table or C-arm without any radiation. Because you can position patients without additional fluoroscopy, dose reduction is possible – making CAREposition an ideal choice for long procedures.
CAREvision
CAREvision enables variable fluoroscopic pulse rates ranging from 30 p/s to only 0.5 p/s, which can considerably reduce radiation exposure for patients and staff. When using 7.5 p/s instead of 30 p/s, for example, dose saving of up to 75% is possible – without losing image quality.
CAREfilter
During digital acquisition or fluoroscopy, the variable filtration is set automatically according to the patient thickness and the angulation of the C-arm. By adjusting the filter size with CAREfilter, you can achieve up to 50% entrance dose reduction** – with minimal impact on image contrast.
CAREprofile
Using the Last Image Hold as a reference, CAREprofile enables radiation-free collimator adjustment and semitransparent filter position setting. As a result, you can achieve dose savings.
low-dose syngo DynaCT
With low-dose syngo DynaCT, you can perform 3D imaging at the lowest possible dose during treatment ‒ which is especially important for radiosensitive patients like children. You obtain excellent imaging results at only 0.1 mSv.
Low-dose acquisition
Low-dose acquisition provides excellent image quality with a dose reduction of up to 67% in comparison to normal acquisition protocols. One acquisition pedal of the footswitch can be configured as a low-dose acquisition pedal.
CAREwatch
CAREwatch displays the dose area product and air kerma rate or air kerma* at the interventional reference point on the live display in the examination and control room.
CAREguard
CAREguard provides an effective way to control the patient's accumulated air kerma*. Warnings are given on the live display monitor and touchscreen if the air kerma** exceeds one of the three predefined thresholds.
CAREmonitor
CAREmonitor shows the accumulated peak air kerma* according to the current projection in the form of a fill indicator on the live monitor. When your predefined threshold is reached the system warns you and you can consider another C-arm angulation.
CAREreport
At the end of each procedure step, CAREreport automatically creates a DICOM Dose Structured Report and transfers the dose values directly to your Hospital Information System. This information supports you in optimizing dose management for patients and procedures.
CARE Analytics
CARE Analytics presents the information of DICOM Structured Dose Reports in a table format for further analysis. So you can compare, for example, dose given during different examinations and the dose a patient has received on different imaging systems – even in other hospitals. This may result in dose savings.

Image Quality

CLEAR
Whether your patients are tall or short, obese or slender – you need to see. And in order to see, you need optimal image quality that helps you make the right decision for the patient. Our comprehensive range of CLEAR applications automatically enhances image quality and thus helps increase certainty during interventions without increasing the dose.

CLEAR Benefits

  • Achieves optimized image quality
  • Applies comprehensive image processing
  • Customizes the image display to preferences
  • The CLEAR package is standard with every Artis system
CLEARpulse
With CLEARpulse and the use of an optimized X-ray spectrum, the pulse length can be shortened by 43 percent. This not only reduces dosage for the patient but also improves image quality and sharpness.*
CLEARcontrol
Using the unique histogram analysis, CLEARcontrol correctly exposes the entire image. By automatically enhancing the brightness, contrast and spatial resolution throughout the entire image, it provides better vessel visibility near the diaphragm.
CLEARmap
Achieving best possible image quality in Roadmap is crucial during complex interventions. CLEARmap enables enhanced image quality and functionality with less system interactions. Get more out of your system by simplifying your workflow, while saving dose and contrast.
CLEARview
Using a unique dose-adaptive algorithm, CLEARview reduces the noise in low-dose images. It splits a raw image into its parts and removes the noise with multilevel decomposition. Then the image is reconstructed – and the result is a sharper image.
CLEARvessel
The algorithm of CLEARvessel works automatically in the background in real time to enhance the visibility of vessel edges. For each pixel, the system decides whether it’s part of the background or the vessel – and increases or decreases the contrast to smooth the image.
CLEARmotion
Based on a unique algorithm, CLEARmotion automatically detects fine structures and compensates for motion artifacts. This means optimal visualization of small vessels, fine structures, and guidewires in every heartbeat.
CLEARmatch
Patient motion leads to decreased image quality. CLEARmatch keeps the live image while pixel-shifting the mask image in real-time to provide consistent image quality during Roadmap. Get sharper images and enhance your treatment even in challenging situations.
CLEARchoice
With CLEARchoice, you can customize image quality to your individual preferences, whether you like smooth images, more contrast or less noise. Simply choose the image quality you want – independent of patient and dose.
