Introduction
Kitaro is a senior engineer in Hitachi Healthcare Business Unit. He has unique careers at Brigham and Women's Hospital and at Tokyo Women’s Medical University as a medical engineer where he could have experiences for research and development of medical devices and software collaborating clinical teams. And now he is working for producing novel products with unmet ideas for human healthcare. Kitaro has the ability to “produce something from nothing.” This means he experienced the "total product life cycle for medical equipment. Start from designing the concept ideas of medical application, make prototypes both of hardware and software. Evaluating them through clinical trials, applications to be approved, manufacturing , and marketing.

Article
Background: When brain tumors are located near the language area, a test to assess language function is required. During the test, it is practical to display combined information obtained from all the equipment so that the surgeon can confirm the patient's response to the tasks. We developed the intraoperative examination monitor for awake surgery...

Contemporary technological developments revolutionized surgical management of intraaxial brain tumors. The intraoperative MRI (iMRI) and updated neuronavigation permitted for neurosurgeons to perform tumor resection under precise guidance. Neurophysiological monitoring and brain mapping allows precise localization of the cerebral functions and pres...
Conference Paper
Current methods of needle insertion during percutaneous CT and MRI guided procedures lack precision in needle depth sensing. The depth of the needle insertion is currently monitored through depth markers drawn on the needle and later confirmed by intra-procedural imaging; until this confirmation, the physicians’ judgment that the target is reached...

Robotic catheters have been proposed to increase the efficacy and safety of the radio-frequency ablation treatment. The robotized motion of current robotic catheters mimics the motion of manual ones-namely, deflection in one direction and rotation around the catheter. With the expectation that the higher dexterity may achieve further efficacy and s...
Article
During surgery, various images as well as other relevant visual information are usually shown upon request with the help of operating staff. However, the lack of direct control over the display may represent a source of stress for surgeons, particularly when fast decision-making is needed. To present the development and initial clinical testing of...

The objective of this paper is to provide an overview of advanced information-guided surgical management technology of intracranial gliomas implemented in Japan, represented by the Intelligent Operating Theater at the Tokyo Women's Medical University, established in 2000, where more than 1000 patients with various intracranial pathology have receiv...
Article
High Intensity Focused Ultrasound (HIFU) has been becoming a major therapy which is used representing for uterine fibroid treatment. We have been developed HIFU system as well and its feature is that the position of focusing probe can be hand-operated by an operator flexibly so that a focus can be burned effectively. However, accuracy is not stable...
Article
A strange danger exists in a new medical technology. The Ministry of Health, Labour and Welfare and an expert can not judge the strange danger. Regulatory science has a side having to do with a social science how to put compromise with a society.It evaluates an effectivity, a safety and a quality which becomes necessary to a coming to practical use...
Chapter
MRI is used not only for anatomical location and characterization but also for 3D views of sulci and gyri. T1WI-MRI captured with 3D-volume acquired 3D-views of sulci and gyri on fifty healthy volunteers and two patients. The software that we developed analyzed and labeled sulcal patterns of cerebral cortex automatically comparing to a standard bra...
Article
Innovative concept of SCOT (Smart Cyber Operating Theater) presumes development of the computer-assisted system based on dedicated information technology for guidance of the complex neurosurgical procedures and easy assessment of their results by the independent observers. It is based on constant monitoring, recording, co-registration and archiving...
Chapter
As the boundary between glioblastoma and normal tissue is unclear, precise resection is required to reduce the risk of post-operative adverse event such as aphasia and to elongate residual life of the patient by resecting tumor region completely. Surgeons use various information such as preoperative and intraoperative image, surgical navigation, pa...

Contemporary technological developments revolutionized management of brain tumors. The experience with information-guided surgery of gliomas, based on the integration of the various intraoperative anatomical, functional, and histological data, is reported. From 2000 to 2009, 574 surgeries for intracranial gliomas were performed in our clinic with t...
Article
The dedicated intraoperative examination monitor for awake surgery (IEMAS) was originally developed by us to facilitate the process of brain mapping during awake craniotomy and successfully used in 186 neurosurgical procedures. This information-sharing device provides the opportunity for all members of the surgical team to visualize a wide spectrum...
Article
The shortage of nurses who assist operating surgeons exchange surgical instruments has been chronically severe. To compensate for this shortage, we have been proposing and developed three versions of the Scrub Nurse Robot (SNR) system that is capable of functioning as a skilled human scrub nurse in endoscopic and laparoscopic surgery. In this paper...
Article
This study firstly describes current status of surgical robot development and various social barriers for clinical application such as pre-clinical evaluation study, governmental authorization, and commercialization. And then a novel experimental platform as an evaluation environment of newly developed medical devices is proposed. As model cases of...
Article
Identification, analysis, and treatment of potential risk in surgical workflow are the key to decrease medical errors in operating room. For the automatic analysis of recorded surgical information, this study reports multichannel audio visual recording system, and its review and analysis system. Motion in operating room is quantified using video fi...
Article
Gliomas represent the most frequent type of primary intracranial tumors, which originate from the brain tissue itself, have infiltrative growth, unclear borders, and usually affect functionally-important cerebral structures. From March 2000 till March 2010, 839 neurosurgical procedures directed on resection of such neoplasms were performed in the i...
Conference Paper
To compensate for severe shortage of scrub nurses, we have been developing the scrub nurse robot (SNR) system that is capable of functioning as a skilled human scrub nurse, who is able to accurately predict which surgical instrument a surgeon will request next and to give it to the surgeon without any delay. In order to achieve this accurate predic...
