SPAMM (Spatial Modulation of Magnetization) sequences for tissue tagging suffer from fading of the tags due to tissue T1 decay. This fading is especially important in cardiac imaging, since it affects the frames acquired in the second half of the cardiac cycle. On the other hand, breath-hold sequences are difficult to hold along a prolonged exploration. We(More)
This paper presents a novel method which reconstructs any desired 3D image resolution from raw cone-beam CT data. X-ray attenuation through the object is approximated using ridgelet basis functions which allow us to have multiresolution representation levels. Since the Radon data have preferential orientations by nature, a spherical wavelet transform is(More)
UNLABELLED There are not many studies about the intestinal parasitosis (IP) and atopic asthma (AA) relationship, and these show discordant results, possibly due to different studies design and differences in population selection. On the basis of personal results obtained by an epidemiological inquiry designed to estimate the prevalence of enteroparasitoses(More)
Acquisition of proper cardiac MR images is highly limited by continued heart motion and apnea periods. A typical acquisition results in volumes with inter-slice separations of up to 8 mm. This paper presents a super-resolution strategy that estimates a high-resolution image from a set of low-resolution image series acquired in di erent nonorthogonal(More)
