Abstract from Third Malmö Conference on Medical Imaging, Malmö, Sweden. CARE Dose 4D (Siemens Healthineers, Erlangen, Germany) is available on Siemens CT systems and comprises a series of dose-saving technologies in which the tube current is adapted according to patient size, shape and density, whilst maintaining a user-defined reference image quality . The degree of dose reduction using CARE Dose 4D and CARE kV compared using a fix effective mAs was 34-57%, 51-88%, and 56-91% for neck, thorax, and abdomen protocol, respectively. Objectives: CARE Dose 4D modulates mAs through several mechanisms according to patient size and shape, whilst maintaining user-defined reference image quality on Siemens Symbia single-photon emission computed tomography (SPECT)-computed tomography (CT) systems. CARE Dose 4D CARE Dose 4Dumfasst eine Röhrenstrom-Anpassung an die Patientengröße, die Röhrenstrom-Anpassung entlang der z-Achse und die Winkelmodulation des Röhrenstroms. Diese drei Modulationstypen sind dabei je nach Protokolltyp einzeln oder kombiniert aktiv.

Radiation Dose Reduction with Sinogram Affirmed Iterative
The adaptation of the tube current is based on the user defined, image quality reference tube current-time product (mAs). CARE Dose4D™ achieves significant dose reductions with automated dose modulation for individual patient size and shape while producing optimal image quality. CARE kV offers an automated dose-optimized selection of the X-ray tube voltage (kV) depending on the selected type of examination. Because Siemens Healthcare's CARE Dose 4D modulation uses different attenuation curves for different patient age categories (e.g., adult or pediatric), the effect of selecting different patient categories was further explored on the Somatom Definition Flash. CARE Dose 4D combined with sinogram-affirmed iterative reconstruction improved the image quality and reduced the radiation dose in low dose CT of the small intestine Combination of CARE Dose 4D and SAFIRE is shown to decrease the radiation dose while maintaining image quality.
The aim of this step is to synthesise all of the information gathered about the patient’s caries risk (1st D) and any caries lesions (severity and activity) (2nd D) to develop an informed, risk-based, tooth-preserving care plan. Notes: Looking at the mA curve for CARE Dose 4D on, we can see that the plot is linear along the log graph. The gradient of the plot depends on the adaptation strength.
