Care & Clear Whitepaper

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

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

Image Quality

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
