✦ Synopsis

A simple gradient-echo technique is described which uses produce an echo. The data-sampling window extends from T/2 to 3T/2. For 3D imaging, this pulse sequence is repeated large oscillating field gradients to produce three-dimensional NMR images of small (20 mm) moulded plastic and rubber in the presence of two phase-encoding gradients, components. The in-plane resolution is 0.5 mm. The echo time is 128 ms. The method is suitable for imaging soft solid

## Abstract The coregistration of electron paramagnetic resonance (EPR) and nuclear magnetic resonance (NMR) images in three‐dimensional (3D) data space typically involves a process of visual inspection and manual alignment of the images. This is due primarily to the use of separate scanners, which

## Abstract This paper presents an efficient reconstruction algorithm for three‐dimensional scattering objects. The algorithm is an extension of previous work for the two‐dimensional one, and is based on an optimization procedure. From the computer simulations, the proposed method is shown to yield
