Magnetic Resonance Instrumentation :Phased Array Coils: What are the Pros and Cons

The report flows well. It has a structure that has been well thought out. The introduction provides a good glimpse of what the report is about. The introduction details to a good extent a map of how the report is organized. It seems clear from the report that the way forward is with phased array coils. The direction of the research is towards overcoming many of the disadvantages of phased array coils through technological improvements. Among them are technological advancements to address issues related to artifacts and loss of image quality. This is in parallel imaging techniques using phased array coils. It does this while retaining the advances that such parallel imaging techniques already bring to the table. Cost is also something that is to be addressed. Future versions of the technology are expected to bring down costs. Likewise, the low resolutions available in current versions of phased array coils are expected to be addressed with improvements in other aspects of the machines. These improvements include adjusting the FOV and increasing the sizes of the image matrices.
We understand from the report that phased array coils can capture larger amounts of data at compressed time frames. This is so that data processing and image reconstruction times take a hit. This is a tradeoff that is compensated by the fact that phased array coils allow for faster scan times. The overall time from scanning to image reconstruction is still lower compared to alternatives. The report tells us how the process can be further improved by improving technologies tied to image processing, to improve image quality and image reconstruction times.
The overall picture one has from the discussion on parallel imaging is this: parallel imaging techniques using phased array coils are highly flexible. They also have high SNR characteristics. Essentially, parallel imaging can allow for faster times of scan for static spatial ...Show more

Functional magnetic resonance imaging
Functional magnetic resonance imaging or fMRI is a process of mapping brain activities by analysing the modifications in blood flow and oxygenation levels that vary according to neural activities taking place within the brain (Huettel, Song and McCarthy, 2009).

Magnetic Resonance Imaging (MRI)
Figure 1 shows an example of an MRI image from a moving patient. In such cases, use of sedation or general anesthesia is warranted to increase tolerance to an unpleasant but necessary procedure, and to expedite MRI imaging of a distressed patient (Medical Advisory Secretariat, 2003; Shellock, 2011).

Breast Magnetic Resonance
Magnetic resonance Imaging involves the use of powerful magnetic fields and radio frequencies to produce computerized and detailed images of soft tissues, organs and bones, as well as any other internal body structure. Unlike some imaging techniques, such as X-ray or computed tomography, MRI does not require the use of ionizing radiation.
