ABSTRACT
A novel ordering of digital Radon projections co-efficients
is presented here that enables progressive image reconstruc-
tion from low resolution to full resolution. The digital Radon
transform applied here is the Mojette transform first defined
by Guedon et al. in [1]. The Mojette transform is a natu-
ral way to generate redundancy to any specified degree and
has been demonstrated to be useful for redundant representa-
tion for robust data storage and transmission. Combining this
with the wavelet transform facilitates compression, i.e., joint
source-channel coding, along with the additional property of
