Size of smallest spatially resolved regions in an image. It may be anisotropic, e.g. with an asymmetric acquisition matrix or slice thickness, and may be larger than the pixel or voxel.

Use of a magnetic field gradient to effectively eliminate residual transverse magnetization by producing a strong position dependence of phase within a resolution element. See Spoiler Gradient Pulse.

From Philips Medical Systems;
the Panorama 0.23 T, providing a new design optimized for patient comfort, faster reconstruction time than before (300 images/second) and new gradient specifications. Philips' Panorama 0.23 T I/T supports MR-guided interventions, resulting in minimally invasive procedures, more targeted surgery, reduced recovery time and shorter hospital stays. Optional OptoGuide functionality enables real-time needle tracking. Philips' Panorama 0.23 TPanorama 0.2 R/T is the first and only open MRI system to enable radiation therapy planning using MR data sets. The Panorama also features the new and consistent Philips User Interface, an essential element of the Vequion clinical IT family of products and services.

From Siemens Medical Systems; MAGNETOM Avanto with Tim - Total imaging matrix technology. For true whole-body anatomical coverage. For ultra-fast image acquisition. Aids the physician in fast and precise evaluation of systemic diseases like colon cancer, metastasis imaging, vessel diseases, and preventional exams. For claustrophobic patients, MAGNETOM Avanto enables feetfirst exams for nearly all MR procedures. For obese patients, MAGNETOM Avanto supports up to 200 kg (400 lbs), without table movement restrictions. The AudioComfort technology enables up to a 30 dB(A) acoustic noise reduction, that means nearly all clinical routine sequences are running under 99 dB(A).

An array coil combines the advantages of smaller coils (high SNR) with those of larger coils (large measurement field). This type of RF coil is composed of separate multiple smaller coils, which can be used individually (switchable coil) or combined.
When used simultaneously, the elements can either be:
