Medical Image Analysis Lab
Machine-translated · View original
A lab that studies the analysis of medical images and the evaluation of radiation exposure in examinations.
AboutAbout the lab
Analyzing medical images and evaluating radiation exposure.
The Medical Image Analysis Lab studies the analysis of medical images obtained from X-ray examinations such as CT, and the evaluation of radiation exposure of patients undergoing these examinations.
Professor Kuniharu Imai's research keywords are mathematical analysis of medical images, dielectric engineering, and the physical properties of contrast agents.
Associate Professor Chiyo Kawaura investigates the radiation exposure that infant, child, and adult patients receive from X-ray examinations.
In graduate school, the lab belongs to Biomedical Imaging Information Science in the Department of Integrated Health Sciences, Graduate School of Medicine.
Key terms
- Phantom
- A model that imitates the human body, used in examinations and tests. It is used to measure radiation dose in X-ray examinations and to evaluate image quality.
- Metal artifact
- Distortion that appears in CT images due to the influence of metal inside the body.
- Contrast resolution
- The ability of a CT image to distinguish objects with small differences in density.
ResearchResearch themes
The lab works on mathematical analysis of images obtained from X-ray examinations such as CT, and on evaluating the radiation exposure of patients undergoing these examinations. Recent papers and research topics include developing methods to evaluate image quality and clarifying the actual state of medical radiation exposure in patients from infants to adults.
*Illustrative imageEvaluating radiation exposure in CT examinations of infants and children
The lab studies age-specific exposure evaluation and optimization of protection for infants undergoing X-ray CT examinations. It also works on clarifying the actual state of medical radiation exposure in children and adults, and has published studies using phantoms as papers.
*Illustrative imageQuantitative methods for evaluating CT image quality
The lab studies methods for evaluating CT image quality. It has published papers on an analysis method for examining contrast resolution and on a method for evaluating images that contain metal artifacts when titanium seeds are implanted.
