Immersive Radiation Experience for Interventional Radiology with Virtual Reality Radiation Dose Visualization Using Fast Monte Carlo Dose Estimation

Autor: Hiroshi Kondo, Takenori Kobayashi, Hiroshi Oba, Jun'ichi Kotoku, Takeshi Takata, Shigeru Furui, Masayoshi Yamamoto, Kenshiro Shiraishi, Takahide Okamoto

Publikováno v: Interventional Radiology. 5:58-66

For interventional radiology (IR), understanding the precise dose distribution is crucial to reduce the risks of radiation dermatitis to patients and staff. Visualization of dose distribution is expected to support radiation safety efforts immensely.

Autor: Susumu Nakabayashi, Hiroshi Oba, Shigeru Furui, Kenshiro Shiraishi, Takenori Kobayashi, Takeshi Takata, Jun'ichi Kotoku, Hiroshi Kondo, Takahide Okamoto, Masayoshi Yamamoto

Publikováno v: Journal of Medical Systems

For interventional radiology, dose management has persisted as a crucially important issue to reduce radiation exposure to patients and medical staff. This study designed a real-time dose visualization system for interventional radiology designed wit

Calculating and estimating second cancer risk from breast radiotherapy using Monte Carlo code with internal body scatter for each out-of-field organ

Autor: Jun'ichi Kotoku, Kenshiro Shiraishi, Takenori Kobayashi, Shinobu Kumagai, Hiroshi Oba, Takeshi Takata, Takahide Okamoto, Norikazu Arai

Publikováno v: Journal of Applied Clinical Medical Physics

Out‐of‐field organs are not commonly designated as dose calculation targets during radiation therapy treatment planning, but they might entail risks of second cancer. Risk components include specific internal body scatter, which is a dominant sou

Denoising Projection Data with a Robust Adaptive Bilateral Filter in Low-Count SPECT

Autor: Norikazu Arai, Kenshiro Shiraishi, Takashi Chikamatsu, Takao Okamoto, Takahide Okamoto, Jun'ichi Kotoku, Susumu Nakabayashi, Takenori Kobayashi, Shinobu Kumagai, Tatsuro Kaminaga

Publikováno v: International Journal of Medical Physics, Clinical Engineering and Radiation Oncology. :363-375

Low-count SPECT images are well known to be smoothed strongly by a Butterworth filter for statistical noise reduction. Reconstructed images have a low signal-to-noise ratio (SNR) and spatial resolution because of the removal of high-frequency signal

Association between alcohol consumption and mammographic density: a hospital-based cross-sectional study

Autor: Takahide Okamoto, Akemi Ito

Publikováno v: Breast cancer (Tokyo, Japan). 26(4)

Mammographic density (MD), the proportion of radiological dense breast, has been reported to be a strong risk factor for breast cancer in many studies. Epidemiological evidence indicates that alcohol consumption increases the risk of breast cancer. I
