## Abstract In an X‐ray computed tomography (CT), time to scan an object must be allowed to obtain its projection data. If the object is not steady during the scanning, its reconstructed image would contain errors called “motion artifacts.” Recently, two kinds of motion artifact, “blurred image” an

## Abstract Dynamic MRI is restricted due to the time required to obtain enough data to reconstruct the image sequence. Several undersampled reconstruction techniques have been proposed to reduce the acquisition time. In most of these techniques the nonacquired data are recovered by modeling the te

## Abstract To obtain the cross section of an object by using an X‐ray CT scanner, many projections of the object with various angles are required. This also takes time for scanning. If the object moves during this period, the projections would be disturbed causing motion artifact in the CT image.

It is experimentally demonstrated that the image resolution from an in-line Fraunhofer hologram degrades appreciably when the centre of the diffraction pattern from a 5-bar resolution target is located asymmetrically in the hologram aperture. This effect is confirmed and analysed using calculated an

## Abstract Measurement of diffusion and its dependence on direction has become an important tool for clinical and research studies of the brain. Diffusion imaging of the spinal cord may likewise prove useful as an indicator of tissue damage and axonal integrity; however, it is more challenging to

## Abstract Multiphoton microscopy is a powerful technique for achieving three‐dimensional submicron imaging in biological specimens. However, specimen optical parameters such as refractive indices and scattering coefficients can result in the loss of image resolution and decreased signal in depth.
