Early Understanding of Potential Ultrasound on the Human Brain
Individually - A Seminal Treatment Indication
____________________________________________
Ultrasound is acoustic (sound) energy in the form of waves having a frequency above the human hearing range. The highest frequency that the human ear can detect is approximately 20 thousand cycles per second (20,000 Hz). This is where the sonic range ends, and where the ultrasonic range begins. Ultrasound is used in electronic, navigational, industrial, and security applications. It is also used in medicine to view internal organs of the body.
An Excerpt
Back to Behavior Research Institute Inc.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.
