MRI scanner that operates using a standard AC power outlet and is low cost to build. Using a permanent 0.055 Tesla Samarium-cobalt magnet and deep learning for cancellation of electromagnetic interference, it requires neither magnetic nor radiofrequency shielding cages. The scanner is compact, mobile...
Siemens Healthineers presents Magnetom Free.Star, a cost-effective MRI scanner, designed to enable better access to magnetic resonance imaging.

Patients are slid into the giant, oven-like MRI machines like so many hundreds of thousands of loaves of bread; out come remarkable computerized images of their brains, hearts and knees. Out also come high profits for doctors who have invested in the machines and who, critics charge, fill t...
a laser dot or line is projected onto an object from the device while it measures the distance to the surface. The scanner is in motion, so a position of it has to be constantly updated by applying references on the surface or by external tracking methods. Figure4shows examples of facial...
Contrast enhanced magnetic resonance imaging (CE MRI) is the most sensitive tool for screening women who are at high familial risk of breast cancer. Our aim in this study was to assess the cost-effectiveness of X-ray mammography (XRM), CE MRI or both str
To address this need, we developed a small, low-cost, open-interface tabletop MRI scanner for academic use. We constructed and tested 20 of these scanners for parallel use by teams of 2-3 students in a teaching laboratory. With simplification and down-scaling to a 1 cm FOV, fully-...

MRI at2.15 MHz in a low-costHalbach-based scannerHalbach arrays are an attractive approach to building low-field MRI systems due to their relatively high magnetic field strength and very low stray fields. B_0 homogeneity of finite length Halbach arrays is, however, significantly reduced which ...
Scanning was performed using an EPIQ 7G Philips ultrasound machine (Bothell, WA, USA) and the Philips X6-1 ultrasound probe, optimized for abdominal imaging with a frequency range of 6–1 MHz. Minimal force was applied to the probe, which was sufficient to clearly delineate the boundaries of...
