Update #5 Finishing the Infrared CT and starting Ultrasound

Last week, we continued to optimize our reconstruction. The final data set we made still resulted in a distorted reconstruction image, shown below. The sinogram for the data looked accurate, but was blurred around the edges. We believe slowing down the acquisition process in the future will all of to get a smoother sinogram and a more accurate reconstruction.

We also began to make agar phantoms for the ultrasound project. We mixed agar and graphite powder with water, microwaved the solution, and mixed it until it went down to 50 degrees Celsius. Then, we placed a 3D printed mold into the solution to finish making our phantom.

Questions

What parameters of your scanner and scan method influence resolution? Investigate these. 

The angle of the servo motor and speed of rotation.
