NSS Program & Topics

The Yokohama NSS 2021 will be held online simultaneously with the 2021 Medical Imaging Conference and the 28th International Symposium on Room Temperature X-Ray and Gamma-Ray detectors. The meeting, which should have been held in Yokohama, will now offer more flexible opportunities for scientists and engineers working in the field of radiation instrumentation to present new results and discuss the latest developments in a large variety of application fields in the virtual world.

The NSS program basically keeps with the same trends from the past years but it expands to include the latest trends in detector technology, radiation detection, detector materials, new instrumentation techniques, and their implementation in high energy and nuclear physics, astrophysics, accelerators, national nuclear security, and many other applications in various types of radiation environments. As we are continuing the virtual conference from the last year and reflecting on our experiences, we plan to take advantage of more parallel sessions, including joint sessions with the MIC and RTSD, while special topic workshops will cover areas of specific interest. Short courses on a variety of traditional as well as novel topics of interest proposed by the NSS community in Japan are also being offered.

MIC Program & Topics

The IEEE Medical Imaging Conference (MIC)

The IEEE Medical Imaging Conference (MIC) is a leading international scientific meeting to discuss the latest physics, engineering, and mathematical aspects of medical imaging with a particular focus on ionization radiation.

Medical imaging is a continuously growing field while detectors, instrumentation, modern computational methods, and integrated systems are leading the way towards technological advances 

MIC has a unique focus on cutting edge technologies as well as their effective translation to clinical practice. In recent years, interest has increased in applications of machine learning, AI, and other rapidly emerging areas of research which will be also dealt with. Physics and engineering solutions for medical unmet needs are another important topic. 

MIC is an opportunity for students, post-doctoral fellows, and junior and senior researchers from around the world to come together and share their new ideas and results of innovations and scientific endeavors.

The scientific program of the MIC consists of oral and poster sessions, plenary sessions, and a student award session. Regular sessions will be complemented by Short Courses and specialized Workshops covering timely topics in medical imaging and therapy.

MIC Topics

Authors are invited to submit papers describing their original, unpublished work on one of the topics below:

  • New radiation detector technologies for medical imaging
  • Simulation and modeling of medical imaging systems
  • Clinical emission systems (whole-body and total-body systems, multi-modality imaging systems)
  • High-resolution imaging systems (organ-dedicated/application-specific systems including small animal PET and SPECT)
  • X-ray, CT, and other imaging technologies
  • Tomographic reconstruction
  • Corrections for quantitative imaging
  • Signal and image processing, dosimetry, and kinetic modeling
  • Assessment and comparison of image quality
  • Imaging in radiation therapy and image-guided interventions
  • Emerging applications and new concepts in medical imaging

Note: abstracts utilizing deep learning and artificial intelligence will be integrated into the above topics depending on the use case

RTSD Program & Topics

28th International Conference on Room-Temperature Semiconductor Detectors (RTSD)
Yokohama, Japan

The 28th International Conference on Room-Temperature Semiconductor Detectors (RTSD) represents the largest forum of scientists and engineers developing compound semiconductor radiation detectors and imaging arrays operable at room temperature. Room-temperature semiconductor radiation detectors are finding increasing applications in such diverse fields as medicine, homeland security, radiography, astrophysics and environmental characterization / remediation. The objective of this conference is to provide a forum for discussion of the state-of-the-art of room-temperature-operating detector technology based on compound semiconductors, including materials improvement, material and device characterizations, fabrication, electronic readout and applications. To provide a comprehensive review, oral and poster presentations representing a broad spectrum of research and development activities emphasizing semiconductor detectors or imaging devices are sought.

RTSD Topics

Authors are encouraged to submit abstracts on original work related to the following topics:
  • Compound Semiconductor Materials for Radiation Detection
  • Pixel, Strip, Frisch-Grid and Discrete Semiconductor Detectors
  • 3D Photon Tracking Detectors and Image Reconstruction Technology
  • Crystal Growth, Materials and Defects Characterization
  • Properties of Electrical Contacts and Device Fabrication Technology
  • Radiation Damage, Long-Term Stability and Environmental Effects
  • Organic and other Photoconductive Materials for Radiation Detection
  • Scintillator/Semiconductor Array Hybrids
  • Semiconductor Neutron Detectors
  • Detector/ASIC Hybridization, Interconnects and Electronics
