United Imaging uMR 780 3.0T(2016)

Neurological imaging benefits directly from acceleration, since long sequences can be shortened or resolution raised within the same acquisition window.

Musculoskeletal imaging draws on sub-millimetre isotropic acquisition, which allows a single dataset to be reformatted along the plane a joint requires.

Body and abdominal imaging is supported by field homogeneity across a large field of view, which underpins spectrally selective fat saturation.

Cardiac imaging depends on acceleration to bring breath-hold sequences within reach, alongside the gradient performance supplied on the individual system.

Off-centre imaging is supported by the short-magnet design and shimming, which holds homogeneity away from isocentre.

Patients at the upper end of size are accommodated by a 65 cm bore and a table taking 250 kg, which at 3 tesla is often the limiting factor on who can be scanned.

Departments under pressure on capacity are served by acceleration taken as shorter examinations, since throughput follows directly from sequence length.

Less Sampled, More Recovered

Compressed sensing samples k-space incoherently and recovers the missing data through iterative reconstruction, which is what shortens a scan without giving up resolution.

Acceleration to a Factor of 36

The uCS 2.0 platform is published at a maximum acceleration factor of 36 across supported sequences.

Detail at 0.5 mm Isotropic

Sub-millimetre isotropic acquisition allows one dataset to be reformatted in any plane without loss.

Time Spent Either Way

Acceleration can be taken as shorter examinations or as finer resolution in the same window, according to how a protocol is written.

Up to 48 Independent Receive Channels

A high-density receive architecture feeding surface coil arrays, which is what acceleration draws on.

Homogeneity Across a Large Field

A 170 cm short magnet with passive and active shimming, published at 0.055 ppm typical at 30 cm DSV, supporting fat saturation across a wide field.

A 65 cm Wide Bore

Bore diameter is often the limiting factor on who can be scanned at 3 tesla, and this system opens that to 65 cm.

A Table Taking 250 kg

Patient support to 250 kg widens the range a service can accept.

No Routine Helium Replenishment

Cryogen evaporation is zero under normal operating conditions.

The case for the United Imaging uMR 780 rests on how much of k-space has to be filled. Conventional acquisition samples to the density the reconstruction requires, and scan time follows directly from the number of lines acquired, so shortening a scan has historically cost either aliasing or resolution. Compressed sensing changes that by sampling incoherently and recovering the missing data through iterative reconstruction that exploits the sparsity of medical images, and the uCS 2.0 platform is published at a maximum acceleration factor of 36 with sub-millimetre isotropic resolution stated at 0.5 mm or less, so the saving can be taken as a shorter examination or as finer detail. Beneath it sit 32 or 48 independent RF receiver channels feeding high-density coil arrays, a 170 cm short magnet at 3.0 tesla in a 65 cm wide bore with passive and active shimming, a 50 cm cubed field of view, a table taking 250 kg and zero cryogen evaporation in normal use. Diagnostic interpretation remains with the reporting radiologist. The software release, gradient configuration, RF channel count, coil set and magnet condition are provided by the seller at quotation. Medigear.uk lists the system for UK business buyers and can arrange a siting survey, transport, rigging, installation, staff familiarisation, service cover and the supply of spares and consumables.
