Low radiation tomographic reconstruction with and without template information
Preeti Gopal, Sharat Chandran, Imants Svalbe +1
Low-dose tomography is highly preferred in medical procedures for its reduced radiation risk when compared to standard-dose Computed Tomography (CT). However, the lower the intensi…
Sharp images from diffuse beams: factorisation of the discrete delta function
I. D. Svalbe, D. M. Paganin, T. C. Petersen
Discrete delta functions define the limits of attainable spatial resolution for all imaging systems. Here we construct broad, multi-dimensional discrete functions that replicate cl…
Tomographic reconstruction to detect evolving structures
Preeti Gopal, Sharat Chandran, Imants Svalbe +1
The need for tomographic reconstruction from sparse measurements arises when the measurement process is potentially harmful, needs to be rapid, or is uneconomical. In such cases, i…
