  2. 2. A Brief History of CT Computed Tomography (CT) has its roots in the early part of this century. In 1917, the Austrian mathematician, Johann Radon (1887-1956) described a mathematically rigorous inversion formula for reconstruction of an object from its projections. Although Radon’s work fell into obscurity after the First World War, the problems of image reconstruction were tackled by Ronald N. Bracewell (1956) in the field of astronomy and William H. Oldendorf (1961), an American neurologist frustrated by the inadequacy of X-ray images, devised an electronic apparatus designed to overcome existing technical and computational difficulties. In the late 1950s, Allen McLeod Cormack (a physicist) proposed that if sufficient X-ray views were taken at different angles, a cross-sectional matrix of mathematical coefficients could be calculated. These coefficients could then each be given a value of intensity on a grey scale from which an image of the internal structure or anatomy of the object or body being studied could be constructed. His early studies led to a mathematically accurate way of quantitatively reconstructing cross-sectional images from x-ray projections. In the late 1960s, the British scientist Godfrey Hounsfield was independently developing his ideas that mathematical techniques could be used to reconstruct the internal structure of the body from a number of x-ray measurements. He concluded that quantitative tomographic techniques could produce up to 100 times more accurate measurements than conventional radiographic methods. This realization motivated the construction and testing of several prototype scanners in the Central Research Laboratories of Elector- Musical Instruments Ltd. (EMI). These efforts eventually resulted in the construction of the first clinical X-ray CT scanner of the head, called the EMI brain scanner, which was installed at Atkinson Morleys Hospital, Wimbledon, England, in 1971. With the successful introduction of the EMI brain scanner into the clinical arena, an explosive development and marketing of CT scanners started with an increasing accumulation of published data in the early 1980s. The potential utilization of 3D imaging in biomedical research is now being explored. During its 25-year history, CT has made great improvements in speed, patient comfort, and resolution. As CT scan times have gotten faster, more anatomy can be scanned in less time. Faster scanning helps to eliminate artifacts from patient motion such as breathing or peristalsis. CT exams are now quicker and more patient friendly than ever before. Tremendous research and development has been made to provide excellent image quality for diagnostic confidence at the lowest possible x-ray dose.

  3. 3. In March 2013, International Atomic Energy Agency (IAEA) has organized regional training course hosted by Centre for Applications of Nuclear Technique in Industry (CANTI), Vietnam Atomic Energy Agency (VAEA). This course is a part of the IAEA technical cooperation activities for knowledge and technology transfer to the ASEAN developing country on Industrial Process Single Photon Emission Computed Tomography (INSPECT). The course took place at the Best Western Dalat Hotel, Dalat, Vietnam, from 11-15 March 2013 and attended by 20 participants from Bangladesh, China, India, Indonesia, Malaysia, Korea, Myanmar, Pakistan, Philippines, Sri Lanka, Thailand, and Vietnam. Mr. Mohd Amirul Syafiq Mohd Yunos and Mr. Roslan Yahya who is MyCT’s member from Malaysia was elected and has been invited to participate the course. Malaysian Society for Computed Tomography and Imaging Technology (MyCT) IAEA/RCA Regional Training Course on INSPECT at Vietnam. 1st MyCT Members Meeting at Sama Sama Hotel KLIA 1st CTiG Board Meeting in 2013 was held at Sama Sama Hotel, KLIA. The one day meeting took place on 15th January 2013 and attended by top management of CTiG. This meeting was organized by Malaysian Nuclear Agency together with University Kebangsaan Malaysia (UKM). The main purpose of this meeting was to create a new society which based on Computed Tomography and Imaging Technology. This idea was proposed by our Chairman, Dr. Jaafar Abdullah since CTiG was established from 2012, it was attracted many researchers, practitioners and expertise from various organizations to participated. The new name proposed for this society is “Malaysia Society for Computed Tomography and Imaging Technology (MyCT)”. One of the main objective of this society is to organised and shall be exclusively operated for the purpose of advancing scientific, engineering and technical knowledge in the field of computed tomography and imaging technology through education, R&D and the compilation and dissemination of relevant information useful to members and beneficial to the general public. Moreover it is also the purpose of the society to establish linkage with other technical and scientific organisations in the dissemination and exchange of information in enhancing the promotion of the advancement and recognition of computed tomography and imaging technology practice in Malaysia. Under this society also will be create a new sub-committee such as committee of Technical & Training, Publication & Promotion, Research & Development (R&D) and Human Capital. The 2nd meeting in this year will be held in Universiti Teknologi Petronas (UTP), Tronoh, Perak on 30th May 2013.
  4. 4. The introduction of open source software in computer imaging, with its source code made available and licensed with an open source license, has given some light in medical imaging research . Open source software is normally developed by the higher learning institutions or research centres which later shared their codes in the internet for other researchers to use. Examples of open source software that are normally used to interpret CT images and published in academic journals are 3D Slicer (www.slicer.org), Osirix (www.osirix-viewer.com), and MITK (www.mitk.org) (Fig. 1 and 2). These open source software are freely available and could be downloaded from the internet anytime and from anywhere. Not only this software could analyse CT images and produce results similar to commercial software, their application or framework is flexible and extensible. In other word, the application could be modified and tailored to the researchers’ needs by extending the available source code. The question of validity and reliability of the open source software is essential in analysing CT images for clinical investigation and assessment. The open source software has been tested in several studies and the authors suggested that they are valid and reliable. Therefore, open source software is appropriate and relevant for processing and analysing CT images in clinical applications. Fig. 1.

Computed tomography (CT) scan is a procedure used to capture images of the inside of the human body. These images are used in diagnostics, as teaching tools, and in routine healthcare for a variety of conditions. With the growth of computers and imaging technologies, medical imaging has greatly influenced the medical field. It is possible to extract quantifiable information from slices taken through different parts of the ‘living’ human body. Structures in the CT slices are directly comparable to physical slices, which may be quantified to extract useful three-dimensional (3D) information. Analyze (Mayo Clinic, USA) and Mimics (Materiliase NV, Belgium) are two examples of commercial software that are widely used for medical image analyses. The software is comprehensive and renowned among medical practitioners and researchers. However, they are expensive to purchase and maintain, which may be a limitation for small research institution planning to start up an imaging department facility.
