Deeper Study 3

This page contains links relevant to the MRI deeper study.

Mathcad simulation of sinc excitation pulses. Download this file, save it and then open it in Mathcad on a PC. You can alter the parameters to see the effect on the Fourier transform of the pulse (for flip angles less than 90 degrees, the FT is closely related to the slice profile).

Note: depending on which browser you are using, and how it is set up, the file sinc1.mcd may be displayed as text in your browser window (rather than either prompting you to save it or starting Mathcad automatically). If this happens, take the following steps:

1. select all of the text in the browser window (use Select All from the Edit menu, or use ^a)

2. copy the text to the clip-board (use Copy from the Edit menu, or use ^c)

3. create a new, empty text file (on the Desktop, or elsewhere)

4. open the text file in Notepad, and Paste from the clip-board use (Edit/Paste or ^v)

5. save the text file, then change its name to sinc1.mcd
