| Outline of Research at the Start |
Current tracking techniques for pancreatic cancer in carbon ion radiotherapy are invasive and require additional irradiation, or have poor robustness. This research will focus on the development of an accurate real-time markerless tracking system, which will be based on surface image guided radiation therapy and deep learning. The tracking system will detect the 3D surface of the patient using a camera and predict the target location at any time during treatment.

| Outline of Annual Research Achievements |
Pancreatic cancer is one of the most lethal cancers. One in three deaths in pancreatic cancer patients is related to tumor progression. Therefore, treatment methods that improve local tumor control may lead to better overall survival. The purpose for this year was to focus on developing a prediction model for the location of the target based on the surface of the patient, which will be the basis for the research. The following steps were taken:
・ Acquisition of patient data, data preprocessing, and mining
・ Use of recurrent neural networks to create prediction models for the location of the tumor.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
It took a lot of time to collect and prepare all the data. The model is still under development because of the long calculation times and difficulties in solving technical difficulties during implementation.
There were also some delays in completing the GPU workstation for creating the prediction model.
|
| Strategy for Future Research Activity |
Complete the prediction model and continue as initially planned.
