RadioProcessor-G
II. Board Installation
Installing the RadioProcessor-G
To install the board you must complete the following three steps:
1. Download and install the latest MRI SpinAPI software packages on your computer. MRI SpinAPI is
http://spincore.com/products/RadioProcessor-G/
•
MRI SpinAPI is a custom Application Programming Interface package developed by SpinCore
Technologies, Inc. MRI SpinAPI is designed to be used only with the RadioProcessor-G.
MRISpinAPI can be utilized using C/C++.
•
MRI SpinAPI can be supplemented with the 'MRI SpinAPI Examples' package. A shortcut to
the location of these files is created automatically in the Windows Start Menu at
“
Start>Programs>SpinCore>MRI SpinAPI
”.
2. Shut down the computer. Insert the RadioProcessor-G card into an available PCI slot and fasten the
PC bracket securely with a screw.
3. Turn on the computer and follow the installation prompts.
4. In order to ensure the maximum accuracy of data acquisition for the RadioProcessor-G, the
adc_offset.exe program needs to be run. This program will produce a value that you will need to use
to configure the ADC of the RadioProcessor-G, so please record this value for future reference. For
more details as to how to utilize the ADC Offset in a program, please refer to Section IV. Example
Gradient Echo MRI Experiment in this manual.
Testing the RadioProcessor-G
The simplest way to test whether the RadioProcessor-G has been installed properly and can be controlled
as intended is to run a simple test program.
Example_1.exe
that accompanies the MRI SpinAPI Examples
package (located at C:\SpinCore\MRI SpinAPI if the default installation directory was used) will produce a
pulse with an on time and an off time of 500 ms on the two digital out BNCs with a duty cycle of 50%. This
sequence will be repeated indefinitely until the program is exited by pressing any key after the board begins
running. These outputs can be observed on an oscilloscope to confirm operation of the digital outputs.
Example_2.exe
can be used to test the analog gradient outputs. Run the program and observe the three
channels on an oscilloscope to check correct operation according to the program's description. This program
will repeat until the program is exited by pressing any key. The board will be programmed one last time,
triggered, and reset to zero the analog outputs.
After these two examples have been run, the
2D_MRI.bat
sample program can be run to test full
functionality. This sample program can also be used to simply test the RF output. A description of the gradient
echo pulse sequence and sample program can be found in the next section.
NOTE: There are additional programs in this folder. More information on these programs can be seen in the
“Tips on obtaining data using the gradient echo example“ section.
