South Side Science Festival demos 2022 SouthSideScienceFair.pdf for handout.
Main MRI Code to Run. Be able to...
- Visualize C chord as waves with certain frequencies (major C, E, G)
- Visualize fourier transform that we perform to hear the individual notes
- Introduction to planar waves and fourier domain in 2D and connection to sound waves
- See planar wave and FT as it rotates
- See planar wave and FT as it rotates and changes frequency
- watch image construction of an MRI brain scan as k-space is collected
- See comparison between the guitar C chord and the MRI image
Shows how frequency, orientation, and phase is shown in 2D fourier space.
Distance from center = frequency
Angle from horizontal = tilt
Complex portion = phase
This took an image of a brain and showed reconstruction of the image through superposition of 2d planar waves of varying frequencies and the corresponding location of those in k-space. The pickle files were saved in a data folder to save computation time and energy.
Display the interactive CT reconstruction display with python3 ct-recon.py.
Click on different angles within the CT gantry to show how the output image changes.
The user must supply the input images in their own data directory (CT/recon_process/) for this to run.
Example of the interactive display:
