Neil,
I think you're talking about the edges of the shimmed volume of the magnet, or the coil.
Magnets are shimmed to a specific volume in the field (every model magnet is different). When you attempt to scan an object that reaches the edge of this volume you will see distortion from imaging the unshimmed area of the magnet.
Also shimming large objects that exceed the range of the receiver portion of the coil will cause distortions.
Hopefully this answers your question?
Good Luck,
Dan McGuan

hello
does anyone know what kind of jobs can people with a degree in Biomedical engineering(MR imaging) seek in the industry. Also does anyone know about any specific websites for the same.
thanks
Rajani

| Metalic particles into the cornea |
For my personal opinion, it is not to expect that these microscopic steel particles are a contraindication for an MRI of the head. An injury of the patient by dislocation or
torque presents not a real risk because of the small size.
The possibility of heating is minimal and can be additional lowered by reducing the SAR. Artifacts may reduce the image quality a little, but diagnostic brain imaging is certainly possible. The use of a mid or low field MRI machine will also reduce any risks.
Hope this will help.

Like lily lily we use a muliphase MRA with 3 phases (artery, portal vein and late phase).
We use an amount of 30 ml Gadolinium with an injection rate of 5 ml/sec. With this high flow rate, you get a more concentrated bolus and therefore a higher contrast for the second phase. We use CENTRA k-space acquisition and reduce the scan time with SENSE (a parallel imaging technique like ASSET ), this will help for a better timing.

| MR image of an eye |
I have a set of MR image of an eye which is acquired from a commercial surface coil. The questions are:
(1) How do I know there is any eye movement during imaging?
(2) How do I remove the artifact if there is any eye movement? Is there a program to do so?
It is deeply appreciated to have help from you.
