Image resolution and deconvolution in optical tomography.
We present a frequency domain analysis of the image resolution of optical tomography systems. The result of our analysis is a description of the spatially-variant resolution in optical tomographic image after reconstruction as a function of the properties of the imaging system geometry. We validate our model using optical projection tomography (OPT) measurements of fluorescent beads embedded in...

متن کاملResolution enhancement via probabilistic deconvolution of multiple degraded images
We present a maximum a posteriori solution to the problem of obtaining a high-resolution image from a set of degraded low-resolution images of the same scene. The proposed algorithm has the advantage that no prior knowledge of blurring functions is required and it can handle unknown misregistrations between the input images. An efficient implementation scheme of alternating minimizations is pre...
متن کاملHigh resolution image reconstruction in ultrasound computer tomography using deconvolution
Ultrasound computer tomography is an imaging method capable of producing volume images with high spatial resolution. The imaged object is enclosed by a cylindrical array of transducers. While one transducer emits a spherical wavefront (pulse), all other transducers are recording the radiofrequency (RF) a–scans simultaneously. Then another transducer acts as the emitter and so on. In this paper ...
