目的：通过研究CARE Dose 4D技术和SAFIRE后处理技术的联合使用在肺结核低剂量CT检查中的效果，探讨这两种新技术在胸部低剂量CT检查中的价值和意义。

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 purpose of this study was to provide an overview of the Siemens CARE Dose 4D AEC system, discuss practical tips and demonstrate potential pitfalls. Two adult anthropomorphic phantoms were examined using two different Siemens CT systems. 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.

Dose Information Special Modes of CARE Dose 4D For certain examination protocols CARE Dose 4D uses modified tube current modulation, to meet specific conditions, for example: • for Adult Head protocols the tube current is adapted to the variation along the patient’s long axis and not to the angular attenuation profile. 2021-04-16 · ●CARE Dose 4Dの設定 CARE Dose 4Dは，コンソール上で部位別に強い変調から弱い変調まで，細かく選択できるようになっている（図1 ）。「Very Strong」「Strong」「Average」「Weak」「Very ●CARE Dose 4D使用の注意点 Optimizing CT Image Quality - Part 3 - CARE Dose 4D This web-based training will introduce Radiologic Technologists to Siemens’ proprietary dose reduction software CARE Dose4D. The 30 minute presentation will discuss the idea of automatic exposure control for CT examinations and how Quality Reference mAs values and dose modulation curves are Today, computed tomography (CT) systems routinely use automatic exposure control (AEC), which modulates the tube current. However, for optimal use, there are several aspects of an AEC system that need to be considered.

We conclude that the adaptation strengths can be used to obtain user-specified modifications to image quality or radiation exposure to the patient. "CARE Dose 4D dose modulation is utilized for almost every exam to automatically deliver the lowest possible dose while maintaining excellent image quality,” says James Coker, Account Executive at Siemens.
