　In the new school term, two master’s students have joined our group.

Introduction

In our laboratory, we are developing image analysis technology using various clinical images. Our major research theme is technical development using photon-counting technology. We performed the basic research such as the assessment of detector characteristics, the sensitivity correction, the technology development necessary for next-generation mammography using energy integrated X-ray detector that is borrowed from a company. We instructors, a radiologist as professor and a radiological technologist as associated professor guide our students in their studies by collaborating with each other.

Research Theme

1. Improvement of photon counting technique using radiation metrology

Image generation using photon counting detector

Conventional medical x-ray imaging depicts the integral value of x-ray energy passing through  human body. On the other hand, a photon counting detector can analyze x-rays individually and discriminate the x-ray energy. New x-ray images (effective atomic number image and high contrast image) can be generated by using a photon counting detector. In this study, to improve the photon counting technique in mammography examination, we devise analytical approach of appropriate x-ray energy information using radiation metrology. (Tomonobu Haba)

Annual Events

Laboratory Meeting

Once a week, graduate students introduce and discuss about the progress of their research projects using slides. Undergraduate students also attend the meeting.

Academic conference presentations

Faculty members and graduate students, including the Japanese Society of Radiological Technology, Fujita Medical Society, present at the conference.  Graduate students also present the contents of their research at seeds-needs networking events.

Laboratory activities

Several times a year, we hold the parties with our undergraduate and graduate students.
We will prepare for a hiking of nearby mountain, so called Futamura mountain having long history, sometime soon.
