Generally, the MRI apparatus is a low-field (0.5T) system equipped with a high-end data processing unit (DPU) to enable the implementation of structure aware (SA) recovery in clinically relevant times.Rizwan AhmadLee C. PotterAdam Rich
This network was subsequently applied to noisy images acquired using a low-field MRI scanner. The trained convolutional network yielded sharp super-resolution images in which most of the high-frequency components were recovered. In conclusion, we showed that a deep learning-based approach has great ...
Methods: MRI examinations without intra-articular contrast were performed on 379 patients for knee pathologies over a 4-year period. The MRI examinations were done using a 0.2-tesla scanner utilizing a dedicated knee coil and read by 1 of 3 board-certified, musculoskeletal fellowship–trained ...
On the other hand, the cost savings associated with low-field MRI hardware are obvious. The running costs of a non-superconductive low-field scanner show even greater differences in favor of low-field scanners. Patient anxiety and safety issues also reflect the advantages of low-field scanners....
These images are the first featuring soft and hard tissues simultaneously at sub-Tesla fields, and they have been acquired in a home-made, special-purpose, pre-medical MRI scanner designed with the goal of demonstrating dental imaging at low field settings. We encode spatial information with two...
Clinical trial for Abdominal Pain , Evaluation of Upper Abdomen Imaging With Low Field MRI Scanner (0.4T)
Objective: To evaluate the diagnostic quality of an open whole-body low-field MRI scanner compared to high-field scanners. Materials and methods: Over a pe... T Merl,M Scholz,P Gerhardt,... - 《European Journal of Radiology》 被引量: 124发表: 1999年 An open-access, very-low-field MRI...
In this work, we performed numerical simulation on a two-channel knee coil for low-field (0.5 T) MRI scanner. We are interested in seeing the effect of a sample placed inside the coil on the sample-induced resistance and decoupling between channels. In particular, we observe how the ...
Electromagnetic Interference (EMI) Elimination via Active Sensing and Deep Learning Prediction for RF Shielding-free MRI. This strategy was implemented on a low-cost ultra-low-field 0.055 T permanent magnet MRI scanner without RF shielding. It produced final image signal-to... Y Zhao,L Xiao,Y ...
Given the current level of technology and the reduced operation and maintenance costs compared to middle- and high-field systems, the installation of a low-field MRI scanner may be attractive to many health care facilities, even small ones, thus leading to further deployment of MRI. In this ...
