Improving image quality and optimizing dose in every Artis system.

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. These cutting-edge functions are designed to reduce radiation dosage for both patient and clinical staff to make dose monitoring and reporting easy and structured for the hospital.

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


Dose saving

Advanced dose-saving technologies effectively reduce radiation dose for patient and operator.

  • Reduced operator exposure
  • Reduced patient exposure
  • Improves hospital marketing capabilities
  • Addresses a broader patient mix: dose-sensitive patients (e.g. children)


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.

CAREposition reduces dose by omitting fluoroscopy while repositioning.


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.

CAREvision drives dose reduction by adapting the frame rate.


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.

Discover how CAREfilter with multi-thickness copper pre-filters for skin dose reduction works.


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 syngo DynaCT combines excellent imaging results with substantial dose reductions.

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.

Low-dose Acqusition provides the image quality you need a much lower dose.


Dose monitoring

With the dose-monitoring features, patient entrance dose** control becomes easy and efficient.

  • Better control of accumulated patient entrance dose**
  • Enhanced in-house dose reporting
  • Enhanced transparency regarding dose per case
  • Prepared for future standards, easier to meet required dose levels

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.

CAREwatch makes dose visible on the live display for optimal dose management.


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.

Dose reporting

State-of-the art reporting solutions enable efficient and transparent reporting and documentation of radiation dose.

  • Better patient dose exposure control and greater transparency
  • Advanced knowledge of when a report has to be written
  • Be at the ready when legal authorities ask for dose per case
  • Prepared for future standards

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.

Watch how CAREreport facilitates dose management.

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.


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.

CAREmonitor provides real-time skin-dose monitoring during interventional procedures.

* Patient entrance dose = air kerma; patient entrance dose rate = air kerma rate
