Project Information
Title: Image Reconstruction and processing for portable MRI
Description: As a part of a small portable MRI system with a labview-oriented console and spectrometer, we have developed a package to reconstruct MR images and to improve images.
Products:
(1) Labview Software with 2010
(2) RIO (NI) SBRIO -9602
(3) RF unit (Radio Processor and NI USRP-2920)
The Challenge: (1) Spectrometer for MRI : ( i) with low frequency signal outputs (three, DC to 5 kHz signals) (ii) RF outputs (approximately 100 kHz to 100 MHz arbitrary waveform generator) (iii) RF inputs with a frequency same as (ii) to be demodulated and used as a raw data to reconstruct MR images. (iv) Post processing software for MR images
The Solution:
<insert explanation of how your project works>
(1) Hardware driving software (RF and gradient signal)
(2) Hardware acquisition software (RF)
(3) 3-D reconstruction for for MRI (3-D Fourier transform program with various options)
(4) Image processing software to enhance and understand MR images.
<insert explanation of the benefits gained using LabVIEW and NI tools>
(1) Hardware Accessibility
(2) Easy to understand complex digital image processing and Reconstruction Algorithm
(3) Good as a starting project to develop systems with more options such as medical imaging systems with more complexity. (later in a company etc.)

<reminder: attach VI code (optional)>
(1) Explanation and Source Code for 3-D MRI Reconstruction:
Explanation: 3-D MR image reconstruction is done using a 3-D discrete Fourier tranform with various optional parameters such as zero-appending options, filtering options, image direction change, and selection options with various ROI’s.
