Profile Radiation measurement is one of the technologies by which fundamental information can be obtained in various fields. Radiation extracts the information in microscopic world to the macroscopic world. In the field of engineering, non-destructive inspection by radiation has become an important theme, and there is a need to develop new inspection methods for product inspection and safety assurance in the automotive and plant fields. In order to propose new inspection system by radiation, I am developing a new system using transmitted and scattered radiation imaging.
Research Field(Keyword & Summary)
  1. scattered radiation imaging

    It is a technology that makes it possible to obtain information about the inside of an object from the direction of radiation incidence by acquiring imaging of scattered radiation. We are developing a real-time imaging system with a particular focus on medical applications in the treatment of malignant tumors.

  2. digital signal processing

    We are developing a digital waveform processing method in areas that are not possible with conventional circuits for output signals from detectors. In particular, we are developing a new processing method that makes it possible to acquire energy spectra in high dose rate fields.
