Independent Navigation System for a Surgical Colonoscope
Lilia A. Ochoa-Luna, Carlos Avilés-Cruz, Tanneguy Redance
Pages: 1-6
ABSTRACT:
This paper provides a novel algorithm to attain the independent navigation of a colonoscopy surgical endoscope. First, it introduces a brief description of this issue through the scientist advance for medical robotics. It then makes a quickly count of the existent methods and at the end it provides the basis in order to propose a new alternative solution with help from vision-guidance. That means that images will be processed and interpreted with the purpose of maintaining the endoscope always at the intestine center. All this considered will help us to reduce colonoscopy surgeries consequences and the most important advantage of this new method proposed is that surgeons will accomplish their work easier and more efficiently.


Effect of Magnetic Field on Adhesion of Muscle Cells to Culture Plate
Shigehiro Hashimoto, Keiji Tachibana
Pages: 7-12
ABSTRACT:
The effect of a magnetic field on adhesion of cultured muscle cells to the culture plate has been studied in vitro. An experimental system was manufactured to apply a magnetic field to muscle cell culture. The system consists of a couple of solenoid coils, a culture dish of 52 mm internal diameter, and an inverted phase-contrast microscope. The solenoid coil generates the alternating magnetic field of 13 mT of the effective value at a period of 0.01 s with the electric current of the rectangular pulses. C2C12 (Mouse myoblast cell line originated with cross-striated muscle of C3H mouse) cells were suspended in Dulbecco’s Modified Eagle’s Medium. The suspension was poured into the plastic dish placed on the stage of the microscope. The culture dish was exposed to the magnetic field between the solenoid coils at 29 degrees Celsius. For comparative study, a part of the suspension was poured into the same kind of dish without exposure to the magnetic field at 29 degrees Celsius. The number of cells, which adhered to the bottom of the culture dish, was traced according to the time (<130 min) during exposure to the alternating magnetic field. The experimental results show that adhesion is accelerated with alternating magnetic field of 13 mT.


A Vein Map Biometric System
Felix Fuentes, Dulal C. Kar
Pages: 13-18
ABSTRACT:
There is increasing demand world-wide, from government agencies and the private sector for cutting-edge biometric security technology that is difficult to breach but userfriendly at the same time. Some of the older tools, such as fingerprint, retina and iris scanning, and facial recognition software have all been found to have flaws and often viewed negatively because of many cultural and hygienic issues associated with them. Comparatively, mapping veins as a human barcode, a new technology, has many advantages over older technologies. Specifically, reproducing a three-dimensional model of a human vein system is impossible to replicate. Vein map technology is distinctive because of its state-of-the-art sensors are only able to recognize vein patterns if hemoglobin is actively flowing through the person


Enzyme Computation - Computing the Way Proteins Do
Jaime-Alberto Parra-Plaza, Jaime Velasco-Medina, Eduardo Caicedo-Bravo
Pages: 19-24
ABSTRACT:
It is presented enzyme computation, a computational paradigm based on the molecular activity inside the biological cells, particularly in the capacity of proteins to represent information, of enzymes to transform that information, and of genes to produce both elements according to the dynamic requirements of a given system. The paradigm explodes the rich computational possibilities offered by metabolic pathways and genetic regulatory networks and translates those possibilities into a distributed computational space made up of active agents which communicate through the mechanism of message passing. Enzyme computation has been tested in diverse problems, such as image processing, species classification, symbolic regression, and constraints satisfaction. Also, given its distributed nature, an implementation in dynamical reconfigurable hardware has been possible.

Michael Protogerakis, Arno Gramatke, Klaus Henning
Pages: 25-28
ABSTRACT:
The presented system is part of the research project Medon-@ ix for the safe application of information technology in preclinical emergency health care. It aims at supporting members of the emergency medical services (EMS) at the incident location from a remote Competence Centre. In this paper cases in which a telematic support system can be used will be outlined. This includes the assistance of medical and non-medical staff in emergency incidents. The functional and non-functional requirements for the on site medical devices, the documentation system and the medical decision support system in the Competence Centre will be outlined. This paper also presents a possible hardware and software system architecture approach to a telematic support system.


Simulation of Cell Group Formation Regulated by Coordination Number, Cell Cycle and Duplication Frequency
Shigehiro Hashimoto, Motofumi Toda, Masa Mizobuchi, Takashi Kuromitsu
Pages: 29-33
ABSTRACT:
The effects of coordination number, a cell cycle and duplication frequency on cell-group formation have been investigated in a computer simulation. In the simulation, multiplication occurs in the last three steps of a cell cycle with a probability function to give variations in the interval. Each cell has a constant coordination number: four or six. When a cell gets surrounded by adjacent cells, its status changes from an active stage to a resting stage. Each cell repeats multiplication, and disappears when the times of multiplication reach to the limit. Variation was made in the coordination number, in the interval of multiplication and in the limited times of multiplication. The cells of the colony, which have the larger number of coordination, have reached the larger maximum population and disappeared earlier.


Person Recognition Method using Sequential Walking Footprints via Overlapped Foot Shape and Center-Of-Pressure Trajectory
Jin-Woo Jung, Sang-Wan Lee, Zeungnam Bien, Tomomasa Sato
Pages: 34-39
ABSTRACT:
One emerging biometric identification method is the use of human footprint. However, in the previous research, there were some limitations resulting from the spatial resolution of sensors. One possible method to overcome this limitation is through the use additional information such as dynamic walking information in sequential walking footprint. In this study, we suggest a new person recognition scheme based on both overlapped foot shape and COP (Center Of Pressure) trajectory during one-step walking. And, we show the usefulness of the suggested method, obtaining a 98.6% recognition rate in our experiment with eleven people. In addition, we show an application of the suggested method, automatic door-opening system for intelligent residential space.



A New Approach for Designing Biodegradable Bone Tissue Augmentation Devices by Using Degradation Topology Optimization
Chia-Ying Lin, Chengyu Lin, Scott J. Hollister
Pages: 40-45
ABSTRACT:
The current study proposed a topology optimization method accounting for base material degradation and create a degradable device that retains sufficient stiffness through the degradation process to provide load bearings for tissue regeneration in orthopaedic applications. Degradable materials are less stiff than permanent materials and suffer further stiffness reduction through time when considering those as substitutes to replace permanent materials for many reconstruction applications. Merely replacing the permanent material with a degradable material in the same design may lead to early device failure. Since many degradable materials lose material through bulk erosion without shape change, the proposed optimization method creates a density distribution map for selected time points during degradation. These different density distributions are then linearly superposed using both time and degraded base stiffness weighting factors. In this paper, the method is applied to design a degradable spine interbody fusion cage device from poly(propylene fumarate)/beta-tricalcium phosphate (PPF/β-TCP). The weighted optimization study successfully produced designs that maintained device stiffness better than either non-weighted or conventional designs. Any bulk degrading material can be designed using this process for any skeletal reconstruction application.


Biologically-inspired Adaptive Movement Control for a Quadrupedal Robot
Haojun Zheng, Xiuli Zhang
Pages: 46-50
ABSTRACT:
Biologically-inspired robot motion control has attracted a lot of interests because of its potential to make a robot perform better and the value of such study to understand animals’ behaviors. This paper presented a quadrupedal robot, Biosbot, with variety of motion abilities and adaptability to its environment. We employed biological neural mechanisms, such as central pattern generator, flexor reflex and postural reflex as Biosbot’s control system, meanwhile designed its acts after its animal counterpart, a cat. Biosbot can walk in different gaits, transfer from one gait to another, turn, clear obstacles and walk up and down hill autonomously, to adapt to its environment. The successful walking experiments with Biosbot prove the approach and control model has the ability to improve legged robot’s performances.


Iris Recognition Using Wavelet
Khaliq Masood, Muhammad Younus Javed, Abdul Basit
Pages: 51-55
ABSTRACT:
Biometric systems are getting more attention in the present era. Iris recognition is one of the most secure and authentic among the other biometrics and this field demands more authentic, reliable and fast algorithms to implement these biometric systems in real time. In this paper, an efficient localization technique is presented to identify pupil and iris boundaries using histogram of the iris image. Two small portions of iris have been used for polar transformation to reduce computational time and to increase the efficiency of the system. Wavelet transform is used for feature vector generation. Rotation of iris is compensated without shifts in the iris code. System is tested on Multimedia University Iris Database and results show that proposed system has encouraging performance.


Towards the Use of Super-Resolution in Biomedical Systems-on-Chip
Gustavo M. Callico, Sebastian López, Félix Tobajas, Valentin De Armas, José F. López, Antonio Núñez, Roberto Sarmiento
Pages: 56-61
ABSTRACT:
Super-resolution is a smart process capable of generating images with a higher resolution than the resolution of the sensor used to acquire the images. Due to this reason, it has acquired a significant relevance within the medical community during the last years, especially for those specialties closely related with the medical imaging field. However, the super-resolution algorithms used in this field are normally extremely complex and thus, they tend to be slow and difficult to be implemented in hardware. This paper proposes a new super-resolution algorithm for video sequences that, while maintaining excellent levels in the objective and subjective visual quality of the processed images, presents a reduced computational cost due to its non-iterative nature and the use of fast motion estimation techniques. Additionally, the algorithm has been successfully implemented in a low-cost hardware platform, which guarantees the viability of the proposed solution for real-time biomedical systems-on-chip.

ABSTRACT:
In this research, we constructed functions that are necessary for the operation simulation system which assists medical students to inhibit brain aneurysm from exploding. The system reported in this paper is “detection of blood vessels”, “detection of brain aneurysm” and “route planning to brain aneurysm”. Not only the detection method but also the method to reduce the miss detection is realized for the detection of blood vessel. Finally, the future work will be shown including construction of head model consisting of artery, vein, brain and cranium.


An Introduction to Micro/Nano-Bubbles and their Applications
Tomohiro Marui
Pages: 68-73
ABSTRACT:
Micro-bubbles gradually decrease in size due to the dissolution of interior gases by the surrounding liquid and eventually disappear, leaving some Nano-Bubbles. It has been proved that free radicals are generated during the collapsing of Micro-bubbles. The present introduction focuses on the biological application of Micro/Nano-bubbles, whose practical bioapplications, development of cell-level biological treatment, and concept of cell manipulating device in the next stage of the development are introduced. In addition, the future application of Micro/Nano-bubbles to Bio-computing systems is also discussed.
