[C++/QT] X-Ray simulation and reconstruction toolkit

ctsimulator

=====================

X-ray Computed Tomography simulator written in C/C++ and QT library.

This software allow you to perform (1) X-ray CT acquisition, (2) System matrix generation va siddon's algorithm, (3) Sinogram generation, (4) Image reconstruction with FBP and SART. This program is written for educational purpose, and freely available under MIT license. (c) Sanghyeb(Sam) Lee MIT License

Overview

There are four directories:

• [phantom]: phantom data
• [source]: C/C++ source code
• [windows-binary]: compiled executable for windows

Example

When you start a program, the following window will pop up.

Load phantom data

Use the following menu to load phantom data. The current version comes with 2 phantom data. You can add your own phantom.

Setup up source and detector type

Specify projeciton type and number of bins

Set up detector movement

Specify (1) start angle(degree), (2) finish angle(degree), and (3) incremental angle(degree)

Record forward projecito nand system matrix (A)

Specify number of projections and the system matrix(A). System matrix will be generated using siddon's algorithm. You can also visualize the ray path and show sinogram.

Apply reconstruction algorithm

You can use ART, SIRT, MLEM algorithms to reconstruct the phantom. It will visualize the phantom at each iteration

Compilation

Use Qt 4.4 library to compile the source code
