Two common computer programs used to plan focused ultrasound treatments gave very different answers. One tool used real CT scans, while the other used a fake version called pseudo-CT. The other difference was between two different software platforms called k-Plan and BabelBrain. Both setups produced substantial discrepancies in their simulation results. This means the computers did not agree on the best plan for the treatment.
Before doctors use these tools on real people, we need to know if the plans are trustworthy. The study found that the outputs of k-Plan and BabelBrain have never been compared directly before. This lack of comparison makes it hard to know which tool is better or if they are safe to use together.
Using CT scans carries a small radiation risk. However, the main worry here is that the computer models might not match reality. We need ground-truth validation of current sonication simulation software before widespread clinical adoption. Further optimization of pseudo-CT algorithms is also needed.
This review highlights the urgent need for more testing. Until we have better proof that these simulations match real patient outcomes, doctors should be cautious. The goal is to ensure patients get the safest and most effective treatment possible.
