and the prostate has changed shape or position. If everything can be done intraoperatively, it saves time and hospital resources. Ultrasound machines can come with urology software that uses this algorithm and a plan can be generated in three seconds , compared to more than 20 minutes for manual planning. Also, for the many centers with more inexperienced staff, by using this software, the operator does not need to have had years of practice to be able to produce high-quality treatment plans . And if they are more experienced, they will be able to tweak plans within minutes to get better results. There is no downside because even if there is a problem with a plan, it does not have to be used. The model learns from a large pool of 961 successful cases. “ It’s a pretty large dataset compared to others, so we are really proud of that, ” Tajwar says. “ It works really well when it sees similar shaped prostates. However, in deep learning terms, it’s not big enough. That can be an issue if the prostate is very small or very large, as these are outliers in the data. ” To solve that, they use a simulated annealing optimizer. This extends the planning process to 2.5 minutes, which is still much faster than it would be manually . 6 DAILY MICCAI Tuesday Oral Presentation
