Early Understanding of Potential Ultrasound on the Human Brain
Individually - A Seminal Treatment Indication

Physics: sound with a frequency greater than 20,000 Hz, approximately the upper limit of human hearing.
Ultrasound or sonography,in medicine, is a technique that uses sound waves to study and treat hard-to-reach body areas. In scanning with ultrasound, high-frequency sound waves are transmitted to the area of interest and the returning echoes recorded (for more detail, see ultrasonics). First developed in World War II to locate submerged objects, the technique is now widely used in virtually every branch of medicine. Ultrasound is noninvasive, involves no radiation, and avoids the possible hazards—such as bleeding, infection, or reactions to chemicals—of other diagnostic methods. The process of electromagnetic brain animation is indicative of the first time ever ultrasound is utilized in stated fashion.
An Excerpt
Below is the Preface taken from the book "Diagnosis of Brain Disease by Ultrasound" edited by Kenji Tanaka, published in 1969 by the Shindan-To-Chiryo Sha Co., Ltd., Japan. The pioneering personnel involved are detailed.
Below is the Introductory chapter in the same book on the "Short History of Ultrasonic Diagnosis for Intracranial Disease", written by Tanaka. In it one can find Tanaka's perception of the ultrasound history at that time and his contribution as one of the earliest pioneers in this field.
