There are many cases where one needs to limit the X-ray dose, or the number of projections, or both, for high frame rate (fast) imaging. Normally, it improves temporal resolution but reduces the spatial resolution of the reconstructed data. Fortunately, the redundancy of information in the temporal domain can be employed to improve spatial resolution. In this paper, we propose a novel regulariz...

Background In cardiovascular MRI applications, high spatial resolution is preferable for anatomical evaluation of vascular structures and high temporal resolution is desired in cardiac functional assessment. As a result, current CMR protocol usually includes repeated scans of the same anatomy with different resolution settings. To address this issue, we propose a technique that allows for retro...

In an animal model of prelingual deafness, we examined the anatomical and physiological effects of prolonged deafness and chronic electrical stimulation on temporal resolution in the adult central auditory system. Maximum following frequencies (Fmax) and first spike latencies of single neurons responding to electrical pulse trains were evaluated in the inferior colliculus of two groups of neona...

Contrast-enhanced MRA methods which provide temporal information, such as the 3D-TRICKS technique[1], have tradeoffs between temporal resolution and spatial resolution[2]. Acquiring data with adequate temporal resolution often limits the achievable spatial resolution. It is desirable to have high in-plane resolution along with good temporal resolution. Recently we have shown that angularly unde...

In dynamic contrast enhanced (DCE) MRI, temporal and spatial resolution can be improved by timeresolved angiography with interleaved stochastic trajectories (TWIST). However, due to view sharing, the temporal resolution of TWIST is not a true one. To overcome this limitation, we employ recently proposed annihilating filter-based low rank Hankel matrix approach (ALOHA) that interpolates the miss...

In this paper we give and evaluate the algorithms for a fully automated temporal resolution theorem prover. An approach to applying resolution, a proof method for classical logics suited to mechanisation, to temporal logics has been developed by Fisher. As the application of the temporal resolution rule is the most costly part of the method, involving search amongst graphs, we propose diierent ...

Rammsayer & Brandler (2002) have proposed that auditory temporal discrimination tasks provide a measure of temporal resolution of the CNS which is argued to be partly responsible for higher order cognitive functioning. We report on two studies designed to elicit the nature of the functions underpinning these auditory tasks. Study 1 assessed whether temporal generalisation (TG) might be better c...
