Virtual Phantoms CEO Dr. George Xu presents keynote address to CIRMS meeting

On April 13, 2022, Prof. George Xu delivered a 45-minutes capstone talk entitled ” Radiotherapy Plan QA using Deep-CNN based Multi-OAR Auto segmentation and GPU-accelerated Monte Carlo Dose Check ” for the CIRMS annual conference. Professor Xu introduced the history of computational phantoms, the VirtualDose software (For tracking patient organ doses from CT and interventional radiology procedures), DeepViewer software (an AI-based automatic multi-organ segmentation tool for radiation therapy) and ArcherQA software (the fast Monte Carlo simulation software for radiation treatment based on GPU acceleration). CIRMS(Council on Ionizing Radiation Measurements and Standards)is the highest academic institution in the field of ionizing radiation measurements and standards in the United States. Its leaders are top experts from industry, academia and government. Through publication of “Needs” report, CIRMS sets national priority in research and development pertaining to ionizing radiation measurement and standardization covering nuclear energy, industrial irradiation, medicine, and nuclear security in the United States. Prof. Xu was elected the President (1999-2000) of the CIRMS, and was chosen to receive the Randall S. Caswell Award in recognition of his outstanding contribution in...

Dr. Xu Presents Webinar to International Organization for Medical Physics – Wednesday, October 6, 2021

Virtual Phantoms CEO Dr. X George Xu has been invited to present a webinar to the IOMP entitled “New Tools of Phantoms, Monte Carlo Calculations, and AI for Medical Physics Applications” on Wednesday, October 6, 2021. He will speak about: Estimation of organ doses in medical physics depends on computational phantoms and Monte Carlo calculations ─ two tools that have seen major advancement recently. Phantoms have evolved from the 1st-generation stylized phantoms to 2nd-generation voxel phantoms, and to 3rd-generation boundary representative (BREP) phantoms. Aided with the latest deep-learning image segmentation tools, patient-specific phantoms can be created consisting of organ outlines ready for Monte Carlo calculations. And GPU-based Monte Carlo codes can reduce dose computing time from hours to less than one minute. This presentation will cover: (1) Historical review of computational phantoms and Monte Carlo codes, (2) Development of patient-specific phantoms using an automatic multi-organ segmentation tool, DeepViewer, that is based on neural convolutional network (called U-Net) , (3) Development of rapid Monte Carlo dose calculation code, Archer, that is based on nVidia GPU co-processors and virtual-source-modeling of medical accelerators. Examples in medical imaging dose (CT, PET/CT) and radiation treatment will be discussed.   To join the webinar – register...
