2. X-rays are a type of radiation called electromagnetic waves. It is a quick and painless procedure that gives us images of the structures from the inside of our body. The images show the parts of our body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white. Fat and other soft tissues absorb less, and look gray. Air absorbs the least, so lungs look black.
The most familiar use of x-rays is checking for broken bones, but x-rays are also used in other ways. For example, chest x-rays can spot pneumonia. Mammograms use x-rays to look for breast cancer. With current advanced technology, the amount of radiation from an x-ray is relatively small. For example, a chest x-ray gives out a radiation dose similar to the amount of radiation we are naturally exposed to from the environment over 10 days.
X-rays not only used for medical purposes, but also in the industry such as automotive, aerospace, petrochemical, power generation and other industries. It is a non-destructive testing (NDT) method that examines the volume of a specimen. X-rays and gamma-rays used to produce a radiograph of a specimen, showing any changes in thickness, defects (internal and external), and assembly details to ensure optimum quality in the operation.
This is in consistent of MyCT as to promote its members in further research involving interdisciplinary area in medical and industry for the benefit of the society.

MyCT was registered with the Registrar of Society (ROS) on the 23rd of February 2013. Almost a year after registration with ROS, the first MyCT Annual General Meeting (AGM) was held at UTM Skudai on the 6th of February, 2014. About half of members (26 out of 56 members) attended the meeting which complied to the ruling of ROS where at least double of the committee members or half of the members to attend the AGM to meet the quorum. Four sub-committee were established:- (1) Technical & Training Committee headed by Dr. Jaafar Abdullah, (2) Publication & Promotion Committee headed by Assoc. Prof. Dr. Zainul Ahmad Rajion, (3) Research & Development Committee headed by Prof. Dr. Ruzairi Abdul Rahim and (4) Human Capital Committee headed by Prof. Ir. Dr. Mohd Sobri Takriff. All 15 protem committee members were re-elected as MyCT committee members for the term 2014-2016.

1st MyCT Annual General Meeting
IAEA/RCA Training Course on Radioactive Particle Tracking (RPT) and Single Photon Emission Computed Tomography (SPECT) for Multiphase Process Investigations
Date: 14th - 18th April 2014 Time: 9.00 am – 5.00 pm Venue: Agensi Nuklear Malaysia
IAEA/RCA Training Course on Industrial Radioactive Particle Tracking (RPT) and Single Photon Emission Computed Tomography (SPECT) for Multiphase Flow Investigations is one of the main activities of the project of the IAEA / RCA Project RAS-1-012 titled Characterizing and Optimizing Process Dynamics in Complex Industrial Systems Using Radiotracer and Sealed Source Techniques, which has the primary objective to increase the studies and research on the benefits and commercial applications of the technology for tracking radioactive particles and tracer material for industrial use. The organization of this course has enable Malaysia to achieve technology transfer and exchange of knowledge which in turn has contribute to the development of human capital, strengthen expertise and the socio -economic development. In addition, a local researcher has got the opportunity to foster closer ties and establish cooperation with overseas participants from 12 country - Bangladesh, China, India, Indonesia, Korea, Mongolia, Myanmar, Pakistan, Philiphines, Sri Lanka, Thailand, Vietnam and 3 local participant from Malaysia had a good experience and delivered by course expert, Dr. Jong-Bum Kim from Korea Atomic Energy Research Institute (KAERI) and Prof Dr Shantanu Roy from Indian Institute of Technology Delhi (IIT Delhi), India.

A segmented electrical capacitance tomography (ECT) imager for palm oil process monitoring system is constructed and presented in this work.The goal of this study is to use the process monitoring system as an instrument to upkeep the local and foreign palm oil mill. This is to ensure that the monitoring of crude palm oil (CPO) in conveying pipeline during extraction of palm oil mill process flow process is efficiently controlled. The system has the capability to visualize the percentage of liquid that exist within the vessel therefore the data can be utilized to design and create better process equipment in mill process. It will also be used to control some processes in order to boost the quality of crude palm oil and the POME (Palm Oil Mill Effluent) treatment process. Most ECT in earlier research were created rapidly and utilized well in multiphase flow measurement in numerous applications such as in oil and gas industries, gas/solids cyclone, milk flows and fluidized beds. Experimentally, this work investigates the capability of using a twin-plane segmented ECT sensor with 16 portable electrodes using two differential excitation potentials transmitted signal in order to recognize the concentration and velocity profile as well as the phase concentration of crude palm oil related multiphase systems (liquid and gas). The attained concentration profile which is received from the capacitance measurements is capable to provide image of the liquid and gas mixture in the pipeline therefore, the separation process (between oil and liquid waste) becomes much easier and the crude palm oil’s quality can be dependably monitored. The visualization results deliver information regarding the flow regime, superficial velocity and concentration distribution in two-phase flow-rate measurement system incorporating a liquid flow measuring device. The information obtained is able to help in the process equipment designing, verification of existing computational modeling and simulation techniques. It may also assist in process control and monitoring during the palm oil extraction process.
Intracranial volume (ICV) is defined as the volume within the cranium, including the brain, meninges, and cerebrospinal fluid. Several methods of ICV measurement had been established and the manual method is considered the gold standard. However, obtaining the ICV via the manual method by assessing every slice of the computed tomography (CT) images is laborious and time consuming. Therefore, alternative methods which reduced the time in measuring the ICV without sacrificing their accuracy and reliability should be established. The aim of this study was to evaluate techniques of ICV estimation for pre- and post-operative ICV of patients underwent decompressive craniectomy (DC). A cross sectional study design was employed in 55 patients with CT head scans (41 males, 14 females) who were between 15 to 86 years old. All patients were scanned twice, using the Siemens Somatom Definition AS+ 128-slice (Siemens, Erlangen, Germany) at the Radiology Department, Hospital Universiti Sains Malaysia. CT images with a slice thickness of 1 mm and a matrix of 512x512 pixels were retrieved and analysed using open-source MITK 3M3 software. The ICV was first measured by the manual method and then compared with estimated ICV calculated using Cavalieri and shape-based interpolation methods with 1-in-5 and 1- in-10 sampling strategies. The estimation on ICV using the Cavalieri method with 1-in-10 sampling strategy was repeated three times for reliability analysis using intraclass correlations coefficient (ICC). Bland-Altman plot was used to measure agreement between the manual and the Cavalieri method with 1-in-10 sampling strategy. The mean ICV (± SD) were 1341.1 ml ± 122.1 and 1396.4 ml ± 132.4 for pre- and post-operative CT data of DC patients, respectively. A one-way ANOVA analysis was conducted to compare ICV measurements using the different methods. No significant difference was found in ICV measurement using the manual, Cavalieri 1-in-5, Cavalieri 1-in- 10, shape-based interpolation 1-in-5, or shape-based interpolation 1-in-10 methods for both pre- and post- operative ICV measurements; p = .989 and p = .991, respectively. The intrarater ICC showed a significant correlation; ICC = 1.00. Bland-Altman plot showed good agreement between the manual and Cavalieri methods. In conclusion, the Cavalieri and shape-based interpolation methods gave comparable results in estimating ICV compared to the manual segmentation. Thus, these methods could be used in clinical settings for a rapid and reliable ICV estimation.
