Detection of Defects of BGA by Tomography Imaging
Autor: Tetsuhiro SUMIMOTO, Toshinori MARUYAMA, Yoshiharu AZUMA, Sachiko GOTO, Munehiro MONDOU, Noboru FURUKAWA, Saburo OKADA
Publikováno v: Journal of Systemics, Cybernetics and Informatics, Vol 3, Iss 4, Pp 10-14 (2005)
To improve a cost performance and the reliability of PC boards, an inspection of BGA is required in the surface mount process. Types of defects at BGA solder joints are solder bridges, missing connections, solder voids, open connections and miss-regi

Positioning Training Tool for Radiography
Autor: Toshinori Maruyama, Hideki Yamamoto
Publikováno v: Positioning. :289-300
Accurate positioning reduces the X-ray exposure of the subject and produces a valuable X-ray image for diagnosis. This paper describes the development of a positioning training tool that supports those studying to be radiological technologists in lea

Reconstruction of knee joint image from CT data using positioning doll
Autor: Toshinori Maruyama, Hideki Yamamoto
Publikováno v: 2015 IEEE International Conference on Imaging Systems and Techniques (IST).
Instead of a phantom with a fixed joint, a positioning doll that is the size of an actual adult and has movable joints can be used to practice positioning for radiography. This paper describes the image processing of a knee joint image created from c

Development of image analysis for detection of defects of BGA by using X-ray images
Autor: N. Furukawa, Saburo Okada, Tetsuhiro Sumimoto, M. Mondou, Yoshiharu Azuma, Sachiko Goto, Toshinori Maruyama
Publikováno v: Instrumentation and Measurement Technology Conference. 2:1131-1136
In the surface mount technology, Ball Grid Array (BGA) has been used in a production of PC boards, because of their excellent characters such as high density of the lead pin pitch, better lead rigidity and self-alignment during re-flow processing. Th

Imaging techniques for positioning training in radiography
Autor: Hideki Yamamoto, Toshinori Maruyama
Publikováno v: 2012 IEEE International Conference on Imaging Systems and Techniques Proceedings.
The positioning skill of the radiological technologist is essential for obtaining accurate diagnostic information of an organ and for reducing X-ray exposure in radiography. We previously reported on the development of a computed tomography (CT) imag
