title: Speech control based on statistical model of the speech organs
abstract: A conventional speech modification framework based on direct modification of acoustic parameters, such as spectral envelope and fundamental frequency (F0), is hard to intuitively control speech sounds. In order to solve this problem, I propose a speech control method considering underlying parameters of acoustic parameters, such as movements of speech organs. The proposed method is capable of directly controlling the physical movement parameters (e.g., opening the mouth wide), and the physical movement parameters are reflected in acoustic parameters by using a statistical method. In this talk, I will present results of an preliminary evaluation to investigate the effectiveness of the proposed method.

title: Development of a Cosmetic Prosthetic Hand with Passive Holding and a Wrist Rotator.
abstract: Currently, most transradial amputees use cosmetic prostheses that resemble a human arm. However, cosmetic prostheses are inconvenient in daily life because they cannot be used to hold objects. Optionally, transradial amputees can also use electric prostheses which have the grasping functionality. However, commercial electric prosthetic hands lack the combination of cosmetic features and functionality. In this research, we develop a human-like, lightweight cosmetic prosthesis with passive grasping and a wrist rotator. The proposed hand can grasp various objects using the restitution force of a spring. We add a wrist rotator to our hand, as wrist rotation is difficult for amputees. The proposed wrist rotator is used to adjust the wrist position for grasping or for a neutral position, as needed. We experimentally validate the functionality of the proposed hand by measuring the grasping and pinching force, as well as its ability of holding objects.

title: Development of electric prosthetic fingers with built-in actuators for aesthetic consideration.
abstract: Finger amputees usually use prosthetic fingers. Cosmetic fingers resemble human fingers, but they are inconvenient for working because joints cannot move. Electric prosthetic fingers can move joints with actuators, but they are less aesthetic than cosmetic fingers. In this work, we develop electric prosthetic fingers which combine both aesthetic appeal, through a design similar to a human finger, and functionality, by making PIP and MP joints movable.

発表題目: 装飾性を考慮したアクチュエータ内蔵型電動義指の開発
発表概要: 指を切断した際,通常,義指が使用される.装飾義指は外観が自然であるが,関節が駆動しないため作業には不向きである.電動義指は関節をアクチュエータで駆動できるが,装飾義指に比べると外観が自然ではない.そこで,本研究では指に近い自然な外観でありながら,指のPIP関節とMP関節を駆動することができる電動義指の開発を行う.

title: Motion correction algorithm for ECV Map in cardiac MRI

abstract: Cardiac Magnetic Resonance Imaging is a well-established noninvasive imaging modality in clinical cardiology. Its accuracy in defining cardiac morphology and function are valid for diagnosing ischemic disease. Extracellular volume fraction (:ECV) indicate a value of the myocardial tissue quantitatively and ECV Map has been reported to have a high diagnostic performance by combining with other MRI image. Such as in order to create ECV Map, it is necessary to align the position of the heart between pre-contrast and post-contrast. In my research plan, I introduce the method to align their image.

発表題目:心臓MRIにおけるECV Map作成のための動き補正アルゴリズムの検討

発表概要:心臓MRIは非侵襲的な画像診断装置であり、心臓MRIで得られる機能画像と形態画像は心筋梗塞といった虚血性疾患の診断に有効である。心筋組織の線維化を定量的に示すECVMappingしたECV Mapは他のMRI画像と比較することによって高い診断能を示す。しかし、ECV Mapを作成するためには造影剤投与前と造影剤投与後のMRI画像の心臓の位置を正確に補正する必要がある。本発表では、ECV Map作成のための造影剤投与前後の心臓の位置合わせ手法について述べる。
