To develop and test a four-dimensional (4D) motion model capable of accurately extracting respiratory motion on voxel-by-voxel basis using 4D-CT imaging and deformable image registration (DIR).

To evaluate dosimetric uncertainties associated with the small proton fields using spot-scanning beams used in intensity-modulated proton therapy (IMPT).

To design and test a three-dimensional detector for proton radiography and CT imaging using a volumetric plastic scintillator irradiated with therapeutic high energy proton beams.

To develop a 3D dose reconstruction algorithm capable of generating volumetric dose distributions measured with large plastic scintillation detectors irradiated with photon, electron, and proton beams used in radiation therapy.

To develop and characterize plastic scintillator sheets for in-vivo dosimetry to measure entrance dose distributions for therapeutic photon, electron, and proton beams.

To evaluate a multi-antenna microwave imaging system capable of producing high-resolution three-dimensional images of different phantom models representing abdominal, thoracic, and brain tissues.

HDR cervical brachytherapy requires continuous anesthesia and coordinated execution across multiple clinical teams, yet most workflows are described only by procedural sequence rather than temporal behavior. This study aims (1) to characterize the time requir...
