Super-resolution imaging

Sensor fusion Advanced signal processing

is a sensor-fusion technique where multiple observations of the same ground truth are combined to reconstruct an image with higher resolution than the individual observations.

When it comes to X-ray imaging, technical constraints limit the spatial resolution that a detector can provide. In essence the detector’s pixel size cannot go lower than a threshold value. Applying super-resolution imaging to this problem allows one to improve the spatial resolution of a given setup by recording the same signal multiple times.

Working at μ-VIS X-ray Imaging Centre, I developed a method to double the spatial resolution of a Nikon X-tek micro-computed tomographic imager.
