Manipulation of the data describing two-dimensional magnetic resonance (MR) images can be used to zoom an image, decrease image noise and artifacts by modeling, or emphasize object edges in the field of view. In this paper, a two-dimensional band-selectable digital filtering (2D-BSDF) technique is d

✦ Synopsis
A new method of processing digital images consists of a numerical filter which suppresses normal features producing an enhancement of the abnormality. The resulting filtered image aids the observer in the recognition of the abnormality. The filter is developed from verified normal images in the computer memory. The enhancement of pathologic accumulations with respect to surrounding activity was improved on the average by a factor of 2.6 for 13 lateral brain images.

## Abstract Given several images of the same slice, a linear filter can produce an image in which the contrast‐to‐noise ratio (CNR) between pathological and normal tissues is greater than in any of the initial images. To distinguish the pathology from more than one tissue, the filter should optimiz
A three-dimensional dynamic gadolinium-enhanced carotid artery imaging protocol with 10 sec per phase was evaluated with respect to the acquisition of an arterial-only phase after contrast bolus injection. Subsequently, the eigenimage filter was used to suppress any venous signal based on a differen
Dynamic susceptibility contrast-enhanced magnetic resonance (MR) imaging in tumors is restricted by relaxivity effects, which may obscure any abnormality of first-pass kinetics in the re-circulation phase. The purposes of this study were a) to document the magnitude of relaxivity effects with a vari
A computer software technique has been developed and employed to insert a modified-Wiener-deconvolution filter (an optimal filter) immediately following the quadrature detector of a magnetic resonance imager. The purpose of this effort is to try to suppress the undesirable effect of the noise found
