(2010-07-14)A complex and challenging problem in flow study is to obtain quantitative flow information in opaque systems, for example, blood flow in biological systems and flow channels in chemical reactors. In this regard, MRI is ...
-
(2017-05-31)High field magnetic resonance imaging (MRI) provides improved signal-to-noise ratio (SNR) which can be translated to higher image resolution or reduced scan time. 7 Tesla (T) breast imaging and 7 T spine imaging are of ...
-
(2022-04-11)This work presents a number of projects for increasing accessibility to magnetic resonance imaging and magnetic resonance spectroscopy through hardware and software approaches. First, the feasibility of dynamic 31P MR ...
-
(2014-09-02)Spinal Cord Injury (SCI) is a common injury in incorrect sitting position, sports and car accidents. Noninvasive imaging methods play a critical role in diagnosing SCI and monitoring the response to therapy. Magnetic ...
-
(2016-05-06)Magnetic resonance imaging (MRI) provides high spatial resolution, high-quality of soft-tissue contrast, and multi-dimensional images. However, the speed of data acquisition limits potential applications. Compressed sensing ...

(2013-02-01)The world of clinical magnetic resonance imaging (MRI) is presently dominated by multi-million dollar machines that use large superconducting magnets to generate very high quality images. It is possible to perform MRI at ...
-
(Texas A&M University, 2007-04-25)Parallel magnetic resonance (MR) imaging may be used to increase either the throughput or the speed of the MR imaging experiment. As such, parallel imaging may be accomplished either through a "parallelization" of the MR ...
-
(2016-12-09)A radio frequency parallel transmitter was developed for magnetic resonance imaging. Eight channels of vector modulation and isolating power amplifiers were constructed so that the performance of different amplifier ...
-
(2018-03-02)Alzheimer’s disease (AD) is a progressive neurodegenerative disease that causes cognitive impairment, reduced functional status, and behavioral disturbances. As patients become increasingly impaired across these domains ...
-
(2021-12-06)Contrast is an essential element of magnetic resonance imaging. Good contrast in an MR image is necessary to correctly differentiate between different tissue structures and make accurate diagnoses. However, objects with ...
-
(2016-05-05)Despite great potential, non-^1H magnetic resonance imaging and spectroscopy (MRI/MRS) studies have not been adopted into standard clinical use. This is largely because the signals generated by non-1^H nuclei have limited ...
-
(2017-08-03)No appreciable improvements in incidences and mortality rates of women with ovarian cancer have been made over the last 40 years; this fact alone indicates that scientists and clinicians lack the adequate tools to conquer ...
