Accelerating time-resolved MRA with multiecho acquisition.

A new four-dimensional magnetic resonance angiography (MRA) technique called contrast-enhanced angiography with multiecho and radial k-space is introduced, which accelerates the acquisition using multiecho while maintaining a high spatial resolution and increasing the signal-to-noise ratio (SNR). An acceleration factor of approximately 2 is achieved without parallel imaging or undersampling by ...

Characterizing the origin of the arterial spin labelling signal in MRI using a multiecho acquisition approach.

Arterial spin labelling (ASL) can noninvasively isolate the MR signal from arterial blood water that has flowed into the brain. In gray matter, the labelled bolus is dispersed within three main compartments during image acquisition: the intravascular compartment; intracellular tissue space; and the extracellular tissue space. Changes in the relative volumes of the extracellular and intracellula...

Re-configurable I/O interfaces for modern Data Acquisition Systems

A modern approach to high speed I/O interfacing is proposed through the use of a flexible architecture based upon Field Programmable Gate Arrays (FPGA) and the PCI bus. Three distinct solutions are reviewed, all manufactured according to PMC (PCI Mezzanine Card) standard: one solution is CPU-based and the other two are CPU-less. The reconfigurability of the architectures is emphasized, showing ...

Brain morphometry with multiecho MPRAGE

In brain morphometry studies using magnetic resonance imaging, several scans with a range of contrasts are often collected. The images may be locally distorted due to imperfect shimming in regions where magnetic susceptibility changes rapidly, and all scans may not be distorted in the same way. In multispectral studies it is critical that the edges of structures align precisely across all contr...

Space Environment Data Acquisition with the Kibo Exposed Facility on the International Space Station (ISS)

The Space Environment Data Acquisition equipment (SEDA), which was mounted on the Exposed Facility (EF) of the Japanese Experiment Module (JEM, also known as “Kibo”) on the International Space Station (ISS), was developed to measure the space environment along the orbit of the ISS. This payload module, called the SEDA-Attached Payload (AP), began to measure the space environment in August 2009....
