Scan equation I don't get, HELP
Here's the question:
The approximate scan time of a rapid spin echo sequence with a TR of 3500ms, a TE of 90ms, a 256x256 matrix, 1 exicitation, a 220mm FOV and an echo train length of 5 is______ minutes.

Formal they give is 3500msx1x256/5=?
a.3
b. 8
c. 11
d. 15

I get 179200. What am I missing in my studies and the math?

ARMRIT to ARRT pathway - - - HELP
I think the ARMRIT (ARMPIT) pathway will actually take away jobs from RTs since it is to my thinking that ARMPIT Techs get paid less money and therefore drives the wages down. Also a limited scope ultrasound tech can sit for the ARRT exam as well.

With this economy the way it is, more people WILL lose their jobs and ARMPITS will stick up the environment.

It is just a matter of time!!!

Math equation
Time in msec = TR * #phase_steps * NEX

Time in sec = (TR * #phase_steps * NEX) / 1000

Time in minutes = (-as above-) / 60,000

note: for FAST or TURBO spin echo divide the
#phase_steps by the ETL

MRI Techologist
Sir, Presently me working is Saudi Arabia under the Sponsor Ministry of Heath. I have 7 years experiece in the field of my expertise. I handled different types of machine, such as: Siemens Vision 1.5 Tesla Close MRI, Siemens Corcerto 0.2 Tesla Open MRI, Hitachi Aperto 0.4 Tesla Open MRI and Philips Achieva 1.5 Tesla Close MRI. Im holding a two license one from the Philippine Professional Regulation Commission and the other is from Saudi Council for Health Specialties. At the same time,i have been processing my registration for Heath professional Council (HPC)to be credited in the United Kingdom, London.

Many Thanks,

Philip C. Lledo

Dynamic data of MRI
Hi,everybody. I'm now programming about reconstruction of parallel MRI, but the only problem is that I don't have any dynamic data, so can anyone tell me how can I get the data?
