    ABSTRACT​
    ​
    • Computer Aided Design (CAD) is not only used in the manufacturing field, but it can also
    use in the medical field.​

    • Today CAD tools are tools being employed to bring about exciting new advances
    in biological and medical progress, as they are tackling challenges that in the past decades
    could only been dreamed of being conquered.​

    • CAD has been traditionally used to assist in engineering design and modelling
    for representation, analysis and manufacturing.

    • I​ n Information Technology and in Biomedicine have created new uses for CAD
    with many novel and important biomedical applications, particularly tissue engineering
    in which CAD based bio-tissue informatics model provides critical information of
    tissue biological, biophysical, and biochemical properties for modelling, design, and fabrication of
    complex tissue substitutes. In this presentation we will present some advances of bio-CAD
    modelling and application in computer-aided tissue engineering.​
    INTRODUCTION

    • The medical field is currently using the Information Technology application


    especially in communications and imagining of scanned images such as x-ray and
    Computerized Tomography Scans (CT Scans ).
    • In other areas such as industries involved in the design of product
    development uses the CAD for designing the medical images.
    • Three dimensional models are necessary for the realistic finite element
    analysis of joints and implants. Interfacing directly medical data to CAD
    environment can improve the biomedical analysis of joints and give very useful
    geometric information.
    • With advanced CAD tools, biological models of tissues that are fully immersive,
    virtual reality experiences are now being created.
    What is CAD/CAE..?

    Computer-Aided Design (CAD)


    Computer aided design is the use of computer to aid the creation, modification, analysis, or optimization
    of a design. CAD software is used to increase the productivity of designer, improve the quality of design,
    improve the communications and create a database for manufacturing.

    Computer-Aided Engineering (CAE) Computer-aided engineering (CAE) is the broad usage


    of computer software to aid in engineering analysis tasks. It includes finite element
    analysis (FEA), computational fluid dynamics (CFD), multibody
    dynamics (MBD), durability and optimization.

    Computer aided engineering primarily uses Computer Aided Design (CAD) software, which are
    sometimes called CAE tools. CAE tools are being used, for example, to analyse the robustness and
    performance of design elements.

    The term encompasses simulation, validation, and optimisation of products and manufacturing tools. In
    the future, CAE systems will be major providers of information to help support design teams in decision
    making.
    CAD/CAE on Biomedical Applications

    1. Model Creation from Medical Imaging Data


             It is now technically feasible and relatively easy to use the data generated from medical
    imaging techniques such as Computer Tomography (CT) scans or Magnetic Resonance
    Imaging (MRI) to generate a CAD model.  This technique is now increasingly being used to
    pre-plan surgeries, specifically ones where some piece of medical equipment or prosthetic is
    to be implanted into interfacing tissues, bones, or organs.  The idea is that a patient’s unique
    and complex bone structure can be modelled in a CAD environment from the real-time scan
    data.  At this point in the workflow, it is then feasible within the CAD environment to design
    the prosthetic and even digitally perform the surgery.

    during the insertion of the guide wire and the vascular sheath.
    2. Image Processing And Tissue Identification

                    Wide ranges of tools give us the power to enhance the image data generated by the CT OR
    MRI scanner. it is possible to enhance contrast; perform a fully automatic tissue selection; draw or erase
    tissues on each image as well as localize tissue selection; display the original scanned data along with two
    reconstructed views in the orthogonal planes and move images in each view in real time.

    3. Image Format Recognition And Interface

             A wide range of formats can be recognized and utilized (Philips, GE, Hitachi, Picker,
    Siemens, Toshiba, Elscint). Software tools allow the recognition of almost all image data,
    including technical scan data. The format of the data is automatically detected and images are
    stored as a dataset. Interface problems of transferring data between various medical and
    engineering software packages and formats can be solved. Medical imaging data can be
    interfaced to various software environments as required.

    4. Three Dimensional Reconstruction

      Three-dimensional computer models of selected anatomical structures can be


    automatically developed within minutes  utilizing data of various scanners (GE, Siemens, Phillips,
    etc.). The reconstruction can be viewed from any angle. Real  time rotation along with the ability
    to apply transparency to the model is available. Advanced visualization methods  also allow the
    combination of the model or the images with Computer Aided Design (CAD) objects. For
    example, an  implant design can be visualized in two-dimensional cross sections along with the
    original CT/MRI data to verify  interaction with the relevant tissue and correct positioning.

    5. Anatomical Modeling:-
    CAD Modeling of Anatomical Structures

    Computer Aided Design (CAD) is now a day used for the design of all kind of medical
    devices. Introducing  geometrical information of anatomical structures within a CAD
    environment facilitates the design of any standard or  custom made implants, prostheses or
    relevant components. CAD objects, such as implants, can be imported within the medical data, 
    facilitating their design. The CAD environment serves also as a tool for further modeling of
    the anatomical structures.  Using such an interface, image-based medical design becomes a
    reality.

    CONCLUSION

    • As per the data framed from this interface it is possible to achieve an artificial joint i.e. replacing
    the worn out one accurately by the computer aided design and finite element analysis techniques
    with the output obtained by technique which has shown an accuracy of 0.1mm which is rapid
    prototyping. 

    • This is an amazing fact because if a part is worn out in a convectional machine with the help of
    design of experiments it is replaced but if in a human machine if the part gets worn out it leads to
    miseries and unhappiness.

    •  By the application of these techniques the worn out part such as hip, knee & shoulder joints in
    the human machine can be replaced.
