I made a phantom by Cu wire and Al edge to measure spatial resolution from MTF. My method is based on an article which its method was validated using some other methods.
Now I have a question about how to validate my phantom results to make sure that it works correctly? I couldn't find any similar standard phantoms and I just find bar pattern phantom for spatial resolution test.
Thanks
Faeze Mirafzali You may use the following ways to evaluate your metal wire/edge phantom for measuring the Modulation Transfer Function (MTF):
1. Comparison with a bar pattern phantom: You can compare your results to those of a bar pattern phantom. The bar pattern phantom is a widely used and generally acknowledged benchmark for assessing spatial resolution. If your phantom's findings are close to those of the bar pattern phantom, you may be certain that your phantom is functioning properly.
2. Comparison with a commercial phantom: You may buy a commercial phantom built for MTF measurements and compare your phantom's results with those of the commercial phantom. This might give independent validation of your findings and assist you.
3. Comparison with past experiments: You can search the literature for other studies that utilized a comparable phantom to yours and compare your results to those studies' results. If your findings are identical to past tests, you may be certain that your phantom is functioning properly.
4. Measurement repeatability: You may take repeated measurements with your phantom and compare the results. If the findings are consistent and reproducible, your phantom is functioning properly.
Furthermore, verify that your imaging equipment is properly calibrated and that all aspects impacting MTF measurements, such as picture collection and processing, are regulated and standardized. This can assist to reduce variability in outcomes while increasing dependability.
