In this paper, we propose a trans-skull imaging system of the human brain using an ultrasonic array probe. In it, we employ a cow scapula imitated to human skull and a steel with ditches imitated to cerebral sulci. We scan the phantom consisting of the bone and steel ditches by a 32 channel array probe and obtain the B-mode image. From the B-mode image, we extracted the bone thickness by fuzzy inference,...
There are various cerebral diseases that deform the cerebral shape with region specificity. So it is effective to quantify the deformation change of cerebral gyri. This study introduces new index called gyral deformation index (GDI) that is defined as a ratio of area of gyrus of interest to area of cerebrum in the defined projection plane. To calculate the gyral areas, this paper proposes a gyral...
In this paper, a fuzzy identification method for cellular quantity of bone marrow stromal cells (BMSCs) in artificial culture bones is proposed. We attempt to identify for cellular quantity with an ultrasonic system and fuzzy inference approach. We employ two characteristics: the amplitude and the frequency; the amplitude is obtained from the raw ultrasonic wave, and the frequency is calculated from...
This paper introduces an ultrasound identification system for cellular quantity of artificial culture bone with fuzzy inference. In our method, first, we measure ultrasound wave. Second, we obtain the two characteristics of the amplitude and the frequency. The amplitude is calculated as the Peak to Peak value, and the frequency is calculated from frequency spectrum of transfer-function by using cross-spectrum...
Automated labeling of the cerebral gyri on the cerebral surface is a fundamental work for estimating the regional atrophy of the cerebrum. Estimating regional brain atrophy will help us to diagnose the cerebral diseases. This article proposes a fully automated method for labeling the cerebral gyri using 3D human brain magnetic resonance (MR) images. The proposed method is composed of two steps; (1)...
This paper describes an ultrasonic testing system with a columnar rod. The general ultrasonic probe is affected by transmission pulse for measurement using the direct contact method. However, if we use a columnar rod between an ultrasonic probe and a target object, we can measure without the transmission pulse. This paper describes the measurement system of the object thickness by the rod and fuzzy...
Rotator cuff tears of the shoulder are caused by bruise or age-related deterioration. They have been diagnosed by image diagnosis using magnetic resonance imaging (MRI). MR images provide the anatomical structures such as the muscle, the ligament and the bone by high resolution. However, it takes a long time and requires much effort for physicians to diagnose several tens of MR images. Additionally,...

This paper describes a dentistry support system for root canal treatment using ultrasonic. Presently, no complete method of root canal treatment has proposed. Dentist empirically removes the dental pulp using measures of length of root canal. Therefore, the support system for root canal treatment is required to precisely remove the dental pulp. This paper solves the problem in root canal treatment...
