10:15-11:00 Naohiko Sugita, PhD, the University of Tokyo

• Talk title: Machining process incorporating biomaterials effective for bone regeneration in arthroplasty
• [Abstract] The goal is to develop a machining process incorporating biomaterials effective for bone regeneration in arthroplasty. Temperature, mechanical stress, and form are critical parameters in regeneration of living tissues such as bone. The following investigations are under this theme: (1) investigation of the influence of cutting temperature and load on bone regeneration by the machining process, (2) development of a low power nanoscale machining process and tools, (3) investigation of effective cut shapes for bone regeneration, and (4) development of a biologically compatible machining system as a cutting tool.

11:30-12:15 Yoshikazu Nakajima, PhD, the University of Tokyo

• Talk title: Three-dimensional shape measurement endoscope
• [Abstract] A three-dimensional shape measurement endoscope based on single-view imaging will be introduced in my talk. We propose a novel method integrating shape from focus and shading methods. Our prototype provides surfaces of organ's inner walls within 0.5 mm of error and no lack of the surface in the experiments.

Student / Fellow seminars

Organized by Haytham Elhawary (BWH), Joonho Seo (Tokyo U)

13:45-16:00pm

Held at Room 4-002G, Ledge Building

Talk format: 12 min talk/3 min questions

Moderator: Joonho Seo, the University of Tokyo

13:45 - 14:00: Joonho SEO - Visual servoing system for non-invasive medical treatment using HIFU

• Visual servoing system for non-invasive medical treatment using high intensity focused ultrasound (HIFU). We aim to develop a medical treatment system for renal diseases such as renal calculi and renal cell carcinoma with HIFU's two well-known mechanism, cavitations and heat generation. Clinical use of HIFU system for renal diseases is immature because kidney is one of the moving organs by respirations, manual irradiation of HIFU focus into target in the body can cause a serious safety problem. Here, our research proposes a point/volumetric target tracking system based on ultrasound imaging. Specifically, we estimate the position of HIFU irradiations by registration of bi-plane ultrasound image and preoperative three-dimensional kidney model. The experiment is now conducted with phantom kidney model.

14:15 - 14:30: Young Min BAEK - A surgical robot universally designed for several surgeries

• My research goal is to develop a surgical robot which can deal with variety of surgical operations. The problem of Computer Aided Surgery (CAS) is its high-cost which make it hard to be conducted in wide areas. Also, a burden of patients has become larger to get a benefit from CAS. General-purposed surgical robot faces to mainly two problems; 1) Mechanical Linkage, 2) Modular structure. To solve these problems, we've developed the surgical robot with easily changeable structure. Master and slave structure is employed with real-time operating systems as well. So far, experiments are conducted in two fields such as neurosurgery and eye surgery. We expect applications can be expanded to other fields in near future.

14:45 - 15:00: Toshiyuki OYAMA - Numerical study of bubble motion in liquid

• My topic is a numerical study of bubble motion in liquid. The key of CFD simulation including bubbles is to capture interfaces of bubbles. By front-tracking method, that tracks explicitly positions of interfaces, bubble motion in liquid has been understood for these 15 years. Bubbles of 1 mm diameter rising in water bounce on a free surface between air and water. Applications of bubble motion are not only power plants or mixing towers but also medical treatment in vessels. Bubbles in vessels react on ultra sound. As a result, bubbles oscillate, produce heat and collapse stone in tissue or burn tumor. In my presentation I will speak mainly about bubble bouncing, this is my theme, but also introduce heating vessels with micro bubble and focused ultra sound.

15:15 - 15:30: Toki SAITO - Deformable-model-based 2-D/3-D registration for fracture surgeries

• My research topic is computer aided surgery. Especially, I focus on reconstruction of 3D shape and position estimation from 2D X-ray images. Its final goal is to reconstruct real-time computer tomography imaging using X-ray images, and it provides accurate and safe surgery. As a first step, we proposed an estimation method of fractured bone position and shape using statistical deformable models and X-ray images in a CT-less environment, and it provides fracture reduction path automatically and reduces surgeons' burden. In my presentation, I'll talk about it.
