Obstetrician– gynecologists and other health care providers caring for pregnant and However, these dose levels are not used in diagnostic imaging.

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. Accordingly, there is a large difference in radiation dose dependent on the adaptation strength: a factor of 1.5, 4.5, and 4.6 for neck, thorax, and abdomen protocol, respectively. The DR achieved with different adaptation strengths were determined relative to the dose delivered with CARE Dose 4D inactivated. Owing to adaptation strengths, a considerable reduction (26.6–51.5 % and 27.5–49.5 % for Sensation 16 and Sensation 64, respectively) in the radiation dose was found when compared with using a fixed tube current (Table 1 ). Independent of selected adaptation strengths, the level of image noise throughout the chest phantom increased when CARE Dose 4D was used (p < 0.0001).

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. CARE Dose 4D The CARE Dose 4D system performs automatic tube current modulation according to the patient’s size and X-ray attenuation changes together with real-time tube current modulation during each tube rotation(8). The adaptation of the tube current is based on the user defined, image quality reference tube current-time product (mAs).

The research is based on unused of the application Care Dose 4D on CT Scan Imaging. Another way to influence dose of a 4DCT scan is to change the CAREDose modulation strength, which can be found at CAREDose 4D Configuration.
