Biomedical Instrumentation has been a vibrant and productive area of research at t KMITL over the last three decades. In 1970, Prof.Pairat Thachayaphong, former president of KMITL, developed the first computed tomography (CT) device in Thailand. This research was conducted at Computer Research Center, KMITL, prior to the setting up of the Department of Biomedical Engineering. In 1980, Prof. Manas Sangworasil designed and developed the first commercial Patient Monitor. These units have now been actively employment in Thai hospitals for over 2 decades. Building on this history, the Department of Biomedical Engineering, has joined forces with the Faculty of Medicine at KMITL to design and develop the next generation of medical devices for Thai and international healthcare use.

In conventional x-ray, x-ray exposure parameters are controlled manually. In order to interface with computer, the digital controlled x-ray apparatus was designed and developed. The device can be interfaced with laptop or personal computer to control the operation of x-ray process. The unit can be applied with NDT system, medical imaging system and miniature Computed tomograph.

X-ray Tomography, this project applied the c-arm fluorography to function as computed tomography. The motor control module was installed in the c-arm pivot point to control the rotation of the x-ray source and detector. At one specific rotation angle, an image was captured and used projection data to reconstruct the cross-section image and the 3D model.

Miniature computed tomography was developed to be used in small-animal laboratory. The system uses portable dental x-ray apparatus as x-ray source. Our own-design x-ray detector is a series of a phototransistors coated with x-ray phosphor. The Miniature computed tomography was tested successfully to reconstruct the cross section image of phantom.
