Aspects of the disclosure provide for an x-ray detection device for detecting radiation scattered off of a target during an imaging procedure and generating temporal data indicating the time of occurrence of a pulse of radiation emitted towards the target. The temporal data can be sent to a host device and used to timestamp images generated from the pulses of radiation. The x-ray detection device is portable and can be installed in a catheterization laboratory or imaging environment to detect the occurrence of radiation, without occluding or partially occluding the beam source. Aspects of the disclosure also provide for a system for receiving temporal data generated by the x-ray detection device, and accurately tagging received image frames based on the temporal data.

Temporal data generation with scattered x-ray radiation

A three-dimensional geometric image of an anatomical region is generated from a plurality of two-dimensional echographic image slices of the region. The image slices are filtered using a reaction-diffusion partial differential equation model before being arranged into a voxel space. Each voxel is then assigned a voxel value to create a volumetric data set from which the volumetric image can be rendered. The image is rendered from far to near, relative to a preset viewing direction, by an alpha-blending process. The alpha value at any given voxel can be determined using the magnitude of the density gradient vector at that voxel. Similarly, the direction of the density gradient vector at a given voxel can be used as a surface normal vector for shading purposes at that voxel.
