Kazunori Baba, M.D., Ph.D. was born in 1952. He graduated Bachelor of Engineering from the University of Electro-Communications in 1975. He entered Medical school at the Osaka University and graduated M.D. in 1979. He became Instructor at the Department of Obstetrics and Gynecology, University of Tokyo in 1985. He is presently Associate Professor at the Department of Biomedical Engineering, Graduate School of Medicine, University of Tokyo. He is also Obstetrician and Gynecologist at the Department of Obstetrics and Gynecology, Saitama Medical Center, Saitama Medical School and the Department of Obstetrics and Gynecology, Tokyo Women's Medical University.

Baba first reported on a 3D ultrasound system in 1984 and succeeded in obtaining 3D ultrasound fetal images by using a mini-computer in 1986. This was reported in the Acta Obstetrica et Gynaecologica Japonica. He also applied this system to placental blood flow and breast disorders in 1990 to 1991. Baba wrote a comprehensive book on diagnostic ultrasound in obstetrics and gynecology including 3D ultrasound in 1992 and edited "Three-dimensional ultrasound in obstetrics and gynecology" (Parthenon Publishing), the first book devoted entirely to 3D ultrasound, in collaboration with Davor Jurkovic in London in 1996. In the mid 1990s, Baba collaboration with ALOKA on technology developed at the Biomedical Engineering Department of the Tokyo University and was a driving force in the development of commercial 3-D ultrasound equipments in Japan, and indeed worldwide. In November 1996, with technical assistance from Takashi Okai and Shiro Kozuma from ALOKA®, Baba published in the Lancet initial experience with real-time processible 3-D, which was a procedure simpler than conventional 3D ultrasound rendering basing on the method of 'accoustic impedance thresholding' to identify fetal surfaces in the amniotic fluid. Image quality was very high and required less expensive computers to make the calculations. Baba was invited to speak at the first World Congress on 3D Ultrasound in Obstetrics and Gynecology in Mainz in 1997 and the second congress in Las Vegas in 1999.

Baba was also heavily involved with teaching of ultrasonography. He was active in promoting conventional 2D ultrasound and Doppler ultrasound in obstetrics and gynecology. He gave many educational lectures and made 11 videos and wrote many articles in book chapters and magazines. In 1993 he published: A manual of diagnostic ultrasound in obstetrics and gynecology which was a 7-parts video series.

He also developed a control system for an artificial uterus and succeeded in incubating a goat fetus in the artificial uterus for 3 weeks and is also involved in the development of an artificial heart.

Dr. Baba is a member of the editorial board of "Ultrasound in Obstetrics and Gynecology" and "The Ultrasound Review of Obstetrics and Gynecology".
