Abstract: Embodiments of the disclosure relate to projection-based dose estimation for X-ray systems, such as X-ray imaging systems. For example, in one embodiment, an X-ray system is capable of estimating an X-ray dose based on an intensity profile of the detected X-rays that have passed through a scanned object and an estimated mass of the object. In one embodiment, the intensity profile may be compared to a baseline scan to acquire an estimate of energy interaction with the object.

Abstract: Methods and systems are provided for automated tube current modulation (ATCM). In one embodiment, a method for an imaging system comprises: calculating a desired dose level based on a clinical task, a size of a subject to be scanned, and an image quality level; generating a scan protocol based on a relation between the image quality level and at least one characteristic of the imaging system; and performing a scan of the subject at the desired dose level and according to the generated scan protocol. In this way, ATCM can be optimized based on elements that impact image quality such as the clinical task, the physical characteristics of the imaging system, the individual patient, and the reader's preference.

Abstract: Embodiments of the disclosure relate to projection-based volumetric dose estimation for X-ray systems, such as X-ray imaging systems. For example, in one embodiment, an X-ray system is capable of estimating an X-ray dose based on an energy interaction of the X-rays with respective portions of an object. In another embodiment, the X-ray dose estimate may be provided on a per voxel, per region, and/or per organ basis.
