Abstract: Presented herein are systems and methods that provide for automated analysis of three-dimensional (3D) medical images of a subject in order to automatically identify specific 3D volumes within the 3D images that correspond to specific anatomical regions (e.g., organs and/or tissue).

In certain embodiments, the accurate identification of one or more such volumes is used to automatically determine quantitative metrics that represent uptake of radiopharmaceuticals in particular organs and/or tissue regions. These uptake metrics can be used to assess disease state in a subject, determine a prognosis for a subject, and/or determine efficacy of a treatment modality.

Abstract: An angiogram is a study of blood vessels where an angiographic chemical contrast agent is injected while a sequence of images (typically x-rays) are obtained. The contrast pattern on the sequence of images provides information about the vascular anatomy and physiology. The discovery that contrast in blood vessels varies at cardiac frequency in magnitude and phase, which may be visualized as a spatiotemporal reconstruction of cardiac frequency angiographic phenomena, enables a set of processes for increasing the signal to noise ratio or equivalently the informational content of an angiogram. In this invention, the organization of cardiac frequency magnitude and phase enables equivalent information on anatomy and physiology to be obtained with less dose of injected chemical contrast agent, less x-ray dose, and/or less navigation of the injecting catheter within blood vessels.

The GIB can control x-ray pulse generation and synchronization to optimize image generation while minimizing unnecessary x-ray irradiation.
