(16-19) Kim et al analyzed 32 preoperative patients using a surface coil
and a combined DWI and DCE mpMRI technique at 1.5T in predicting the stage, using RP results as the reference standard.
A submersed enhanced surface coil
is used to extract the energy during peak air conditioning hours.
A hybrid Method-of-Moments/Finite-Element Scheme  simulated the complex sensitivity map of a surface coil
loop at 85.45 MHz (2 Tesla), as shown in Figure 4(a).
Echoes were acquired by using both the double-D surface coil
and the room temperature volume coil in order to compare their performances in terms of SNR.
Additionally, a dual tuned [sup.1]H /[sup.31]P RF surface coil
for MRI and MRS at 7 T has been developed and tested on the workbench.
GE Healthcare's new GEM Suite surface coil
technology is designed to reflect the importance of making the geometry of the equipment and technology compatible with the specifics of every single patient.
A standard head coil is usually adequate; however, a receiver surface coil
can also be used, placed directly over the parotid gland to increase the signal-to-noise ratio and hence the quality of the scan, if necessary.
As an example of our work in MRI safety, Michael Smith of Pennsylvania State University and I used electromagnetic simulation to calculate the RF magnetic field ([B.sub.1]), specific absorption rate (SAR), and SNR as a function of frequency between 64 and 345 MHz for a surface coil
against an anatomically accurate human chest.
Concerns about surface coil
availability, radiofrequency (RF) deposition limits, and higher ambient noise must be addressed.
In order to guarantee accuracy of the down-hole surveys taken during the drilling of the pilot hole, Mears utilized a ParaTrack surface coil
over the entire length of the crossing.
The increased loss from operations reflects the activities leading up to and following the recently received clearance from the FDA which allows the company to begin marketing its Cardiac View Probe and Cardiac View Surface Coil
. Income from interest increased to $59,000 from $20,000 in the prior year period due to the improvement in the company's cash position during the year ended February 28, 2001.
The three types of coils used for MRCP exams are the body coil, surface coil
and torso multicoil array.
