摘要： PURPOSE: To improve signal strength by matching the position of a focus where ultrasonic waves transmitted and received from an ultrasonic converter are gathered inside an acoustic propagation medium by the action of an acoustic lens with the position of the boundary of a viable tissue and the acoustic propagation medium in the range of a focal depth. CONSTITUTION: The ultrasonic waves transmitted from the vibrator 4 of the ultrasonic converter are propagated inside a substrate 3, then converged by the acoustic lens 2 and made incident on the viable tissue 50 and the ultrasonic waves reflected from the viable tissue 50 are received by the vibrator 4. The ultrasonic converter is mounted to the internal needle 10 of this needle-like ultrasonic probe and the scanning of the ultrasonic converter to the surrounding viable tissues 50 is realized by operating the internal needle 10. The liquid acoustic propagation medium 40 supplied by an acoustic propagation medium inlet/outlet tube 30 is interposed between the acoustic lens 2 and the viable tissue 50, the inlet/outlet device of the acoustic propagation medium 40 is attached on the opposite end of the acoustic propagation medium inlet/outlet tube 30 and the position of the boundary of the viable tissue 50 and the liquid acoustic propagation medium 40 is finely adjusted and matched with the position of the focus of the acoustic lens 2 by changing a hydrostatic pressure.

摘要： PURPOSE: To obtain a needle ultrasonic probe which is ideal for the diagnosis of the nature of a tissue and higher resolution photographing thereof at a deep part within a specimen by a method wherein a part having an ultrasonic converter of an inner needle is exposed from the tip of an outer needle during the transmitting or receiving of an ultrasonic wave and the inner needle is moved with respect to the outer needle to scan the ultrasonic converter. CONSTITUTION: An hollow intermediate cylinder 2 for holding is formed inside an hollow outer needle 1 with a puncture needle-shaped tip and moreover, an inner needle 3 carrying an ultrasonic converter 10 is fitted inside. The inner needle is pierced by a signal line 30 to transmit a signal transmitted or received by the ultrasonic converter and a tube 4 to supply or discharge an ultrasonic transmission medium. A driver 31 and a drive controller 32 are attached on an end part opposite to the sharp tip of the outer needle 1 and the inner needle 3 is turned and driven in translation. When the tip of a probe reaches an interest part in the puncturing of the probe into a human body, the outer needle 1 is pulled slightly so that a non-stretching film is broken to expose the intermediate cylinder 2 and the inner needle 3. Thus, the transmission medium is supplied into an organic tissue through a tube 4 in the inner needle to transmit or receive an ultrasonic wave driving the inner needle 3.

摘要： PURPOSE:To protect the secret of investigated data and that of individual data and to safely control picture data by controlling the reference of picture data for medical use and character data which is displayed at the same time as picture data depending on the qualification of a person who refers. CONSTITUTION:Reference control information are independently given to picture data for medical use and character information which is displayed at the same time as picture data for medical use and a device can refer to picture data for medical use 61 and character information 62 which is displayed at the same time as picture data for medical use. A person who controls a work station for medical picture display can register a reference right apart from the registration of the ID and the password of a user. Since picture data for medical use can be controlled in the units of an individual and a group, individual secret information and data for investigation can easily be secured by the individual and the group by comparing reference control information of character information which is displayed at the same time as picture data and picture data for medical use with the reference right of the registered user.

摘要： PURPOSE:To enhance the efficiency of recording an enlarged image, by performing a calculation for enlarging data for the next line while a one-line amount of data already subjected to a calculation for enlargement is recorded on a recording medium. CONSTITUTION:An original image consisting of 1000X1000 pixels is stored in an image memory 2 of an image processor 1. Image data for the first line is calculated for enlargement into 3000 pixels X1 line by a high-speed calculating circuit 3, and the enlarged image data thus obtained is stored into a buffer memory 6. The enlarged image data is read from the memory 6, is transmitted through a signal line 10 to a laser printer 7, and is stored into a buffer memory 11. The printer 7 reads the enlarged image data from the memory 11, and outputs the data to a laser light controller 12, whereby the first line constituted of enlarged images is recorded at a predetermined line position on a recording medium 14. During the recording, the image processor 1 performs a calculation for enlarging data for the second line. Then, the second line is recorded on the medium 14. Thereafter, the above procedure is repeated.

摘要： PURPOSE:To facilitate the input operation without requiring skill, by inspecting a character by a knowledge base, while inputting the character one after another by an input device, inferring a word related to already inputted information, and displaying it as an input candidate word. CONSTITUTION:A knowledge data base 6 in which information is collected at every knowledge of high relativity is prepared in advance, and while inputting a character one after another by an input device 1, it is inspected by the knowledge data base 6, and a word related to already inputted information is inferred and displayed as an input candidate word. In accordance with whether this candidate word coincides with a word which is inputted in the next time or does not coincide, a regular input can be continued by adopting said candidate word as an input word or without adopting it. In such a way, it will suffice that an operator only inputs a character whose input is desired, one after another, and the input operation of a document can be executed easily and quickly.
