In the previous paper, we proposed a liver deformation model based on the beam of structural mechanics for medical training systems using virtual-reality techniques. In this beam model, a liver deformation is approximated by a single-beam deformation. The calculation cost of the single-beam model is much less than that of the FEM since the beam consists of one-dimensional elements. However, the single-beam model takes into account only one point-contact. In this paper, we propose a multi-beam model under the consideration of two point-contacts for laparoscopic training system by expending the single-beam model.

Collision response is an important component in a virtual surgery system, due to the requirements of realtime response and simulation realism. In this paper, we propose a novel hybrid collision response algorithm for generating a smooth feedback force. This algorithm takes the advantages of three traditional methods as well as gets rids of drawbacks of them. It also provides an approach to generate a reasonable feedback force. After collision response processing the variance of feedback force has been reduced from 30026 to 0.0003, form 39095 to 0.06 and from 5455 to 0.008 in x, y and z dimension respectively. The result shows that our methods can be used in a real-time response and simulation realism required haptic surgery simulator.

We developed a new home health care network system called the Home Healthcare Model Verification Project in Japan. In this Project we collected 240 subjects' home healthcare data for 24 months with 10 different monitoring devices, and in this session introduce the Home Healthcare Network in Japan briefly and some findings of gathered filed test data. Finally we suggest some unregulated problems for data analysis.

The increase in the number of medical exams, the need to store images resulting for those exams at a very high quality, and the introduction of teleradiology result in an overwhelm increase in storage and distribution costs of medical images. In this paper we propose a method using JPEG 2000 in the lossless or near lossless modes to encode medical images, in order to reduce image storage costs and in the same time store a very high image quality needed for medical applications. We use JPEG 2000 interactive protocols (JPIP) to allow interactive access to medical images in a way that minimizes the transmission bit rate by first displaying a reduced resolution or quality of the image, then allowing lossless display of regions of interest interactively specified by the image viewer. Our method secures medical images by applying JPEG 2000 specific security tools and is implemented in a way compliant to DICOM standard to ensure interoperability. Simulations and results verify the efficiency of the proposed method.

Picture archiving and communications system (PACS) is widely used in hospitals to bring high efficiency in a medical process. Recently, PACS is required to evolve into a more sophisticated system that can communicate with other medical systems. The existing PACS was designed to be used in a local area network (LAN) of a hospital and DICOM, the standard used in PACS, doesn't have any QoS for file transmission or security functions for an open network. Therefore, we propose a PACS system over Policy Quorum based Resource Management (PQRM) system, which manages storage resources and computing resources in Grid environment to provide satisfying advanced medical services with guaranteed QoS. Finally, we test the real situation medical scenario to prove the advanced functions our system provides and do several experiments to show the superiority of our novel system to existing PACS systems. The results indicate that while PQRM-based PACS providing the ability for advanced medical services it guarantees the transmission, provides best resource selection and disaster recovery capability.

In the analysis of digital or digitized mammographic images, a requirement is to learn to separate benign abnormalities from malignant ones. Such an activity could form part of a computer-aided diagnosis (CAD) tool. We present a CAD study of mass and calcification lesions found in digital database of screening mammography (DDSM) using BI-RADS-based features to demonstrate the performance of feature elimination-based support vector machines as the classification technique. It is shown that using only a subset of the available set of features is shown to significantly better classify abnormalities. Furthermore, it is also shown that CAD of same-institutional mammograms produces higher classification accuracy in general compared to that of cross-institutional mammograms.

Neuroinformatics is a new discipline which combines neuroscience with information technology. The Japan-Node of INCF was established at NIJC at RIKEN Brain Science Institute to address the task of integrating outstanding neuroscience researches in Japan. Each platform subcommittee from selected research areas develops their platform on the base-platform XooNIps. NIJC operates the J-Node portal to make platform resources open accessible in public. We introduce our concepts and the scheme of J-Node including several platforms toward understanding the brain.

In aging societies such as Japan's, the number of elderly person living alone increases. Since the incidence of disease and injury increases with aging, remotely located family members become anxious about the safety of their elderly parent. The elderly parent is conversely eager for information about the remotely located family. To improve smooth communication between the elderly parent and the remotely located family, we developed an inexpensive telemonitoring system of the television's operating state (TVOS). The system is comprised of sensors and a PC with an Internet connection. The TVOS is detected by a current sensor attached to the power line of the television (TV). The PC acquires the TVOS via a USB/PIO unit. The PC at the family's end requires the TVOS from the PC at the elderly person's end to be transmitted via the Internet once a minute. A feasibility test, over one year, was performed in two pairs of parent-child families, Le. four households, living apart. The results showed that (1) a different pattern of TVOS was obtained for each family, and (2) the pattern of TVOS differed between business days and non-business days in the same family.

This study investigates the leg crossing effect originated from meditation. We use pulse transit time as index for this study. Pulse transit time is measured form the time interval between ECG R peak position and the corresponding pulse peak. There are 14 subjects participated in this study and two half lotus leg crossing postures and one free leg stretch posture are required. The PTT results indicate that distance between heart and the limbs is one major factor, and the other factor is the leg crossing postures that hinder the blood flow rate.
