The computerization of the clinical record and the realization of the multimedia has brought improvement of the medical service in medical facilities. It is very important for the patients to obtain comprehensible informed consent. Therefore, the doctor should plainly explain the purpose and the content of the diagnoses and treatments for the patient. We(More)
hh tt tt Abstract— Optical Coherence Tomography (OCT) image is very useful to the diagnosis and the follow up evaluation of the response to treatment using either medication or surgery, and it is an emerging medical imaging technology for performing high resolution cross-sectional images. In ophthalmology, this technology can provide 3D images of retinal(More)
Optical Coherence Tomography (OCT) has emerged as a new technology that enables high-resolution cross-sectional images of the retina for identifying, and quantitatively assessing of the retina disease. Quantitative information of retina is needed for tracking progression of ocular disease and evaluatesthe efficacy of treatment. In this paper, we propose a(More)

Informed consent for patients becomes important clinics where the doctor explains diseases and treatments. But patients have difficulty understanding medical images, i.e. X-rays, CT or MRI because the patient is not expert in reading these medical images. In this paper, we tried to reconstruct the stereoscopic image of CT and MRI and display these using a(More)
Electro-holography can display images without inducing fatigue and three-dimensional (3D) sickness, i.e., visual discomfort due to viewing a stereoscopic display. Thus, this technology is expected to be applied to 3D media. However, there are no studies that have shown the agreement between the dynamic responses of accommodation and vergence to the(More)
Studies on measuring accommodation and vergence responses of human vision are important to evaluate three-dimensional (3D) display technologies. Electro-holography is expected to be an ideal 3D display. However, there has been little research on measuring responses to it. In this study, the static responses to electro-holographic images with a large visual(More)
Three dimensional process could improve the extraction rate in comparison with two dimensional process. We propose a new three dimensional active grid for extraction of retinal boundaries on optical coherence tomography. Ophthalmologist desire a system that can measure retinal thickness automatically for quantitative evaluation on retinal diseases.(More)
