UMRAM researchers have recently published a journal article in Experimental Brain Research. In their study, they focused on brain mechanisms and principles coordinating crossmodal and intramodal perceptual grouping. By designing different experiments on perceived speed, they found that certain spatial grouping principles of vision can take precedence over audiovisual interactions in time. Moreover, their findings […]

In a recent publication from UMRAM researchers, it is shown that simultaneous use of linear and nonlinear gradients provides better B1+ inhomogeneity correction than using only linear or only nonlinear gradients. In high field scanners (3T or above), perfectly spatially homogeneous radio frequency (RF) pulse cannot be achieved inside the body because wavelength becomes comparable […]

UMRAM researchers has recently published an article titled as “A z-gradient array for simultaneous multi-slice excitation with a single band RF pulse”. It is shown that multiple slices can be excited with a single band RF pulse using a custom designed z-gradient array. In recent years, imaging multiple slices at the same time, multi-slice MRI, […]

UMRAM researchers published a novel work in MRM journal in collaborating with UNAM team. This study presents an inductively coupled ultra-thin, flexible, and passive RF resonator for MRI marking and guiding purposes with clinical feasibility. Standard microfabrication processing was used to fabricate the resonant marker. The proposed marker consists of two metal traces in the shape of a square with […]

Umram researchers published a new study for implant safety research under MRI. The project introduces a new in vivo testing method and system for active implantable medical devices. The computer simulations and phantom experiments poorly represent potential temperature increases and Animal experiments could be a better model but heating experiments conducted immediately after the surgery […]
