Over the years, improvements to major MRI scanner system components (for example, magnetic field gradient coils22,23,24and radiofrequency (RF) receiver array coils25) have led to higher signal-to-noise ratio (SNR) and higher resolution imaging or faster image acquisition (acceleration). However,...
Jennifer Abbasi JAMA Key Points Question Can brain injury in patients who are critically ill be assessed using a novel portable, low-field magnetic resonance imaging (MRI) device at the bedside in an intensive care setting? Findings In this cohort study of a series of 50 patients imaged with ...
The understanding of the human brain is one of the main scientific challenges of the twenty-first century. In the early 2000s, the French Atomic Energy Commission launched a program to conceive and build a human magnetic resonance imaging scanner operati
脑大体结构成像 (MRI) 使用9.4T / 30 cm水平孔动物MRI系统使用15 mm体积线圈和基于自旋回波的序列对样品进行成像,参数如下:空间分辨率:60 μm x 60 μm x 60 μm;总扫描时间:7小时12分钟;回波时间 (TE): 6.83 毫秒;重复时间: 40 毫秒;激发/重新聚焦翻转角度:90/180度;图像尺寸:166 x 168 x ...
This study developed a lightweight (350 kg) and low-footprint magnetic resonance imaging (MRI) system for brain imaging. Static magnetic field was built using an H-typed permanent magnet, which has 50.9 mT magnetic field strength (corresponding to 2.167 MHz proton Larmor frequency). Biplanar ...
However, the interpretation of MRI scans is highly reliant on the expertise of radiologists and can be time-consuming, highlighting the need for assistive technologies to improve diagnostic accuracy and efficiency. Deep learning, a subset of machine learning, has revolutionized the field of medical ...
Low-field MRI is a rapidly growing field with a lot of potential, but it also comes with challenges. This paper demonstrates the potential of deep learning-based methods in addressing the challenges in low-field MR imaging. Methods Background Given a low-resolution 2D image \({\mathbf {y}...
