Abstract

An ultrasonic diagnostic apparatus for ophthalmology according to the present invention includes a card connector into and from which a memory card is to be inserted and removed, a microcomputer incorporated in the apparatus, and a card interface for data transfer between the memory card and the microcomputer therethrough. Diagnosis data is obtained based on data of the memory card and data in the microcomputer, whereby even when a new program or data necessary for diagnosis is developed, the apparatus can immediately used the new program or data while eliminating the need for being modified. The apparatus thus can readily reproduce patient data and efficiently diagnose many patients.

Claims

1. An ultrasonic diagnostic apparatus for ophthalmology for diagnostic transmitting and receiving of ultrasonic waves and for outputting a plurality of ultrasonic reflection echo images therefrom, said apparatus comprising:

a card connector into and from which a memory card is to be inserted and removed;

a memory card for storing ophthalmalogy data, said memory card being removably connected with said card connector;

a microcomputer electrically connected to said memory card for controlling an ultrasonic probe and for obtaining data based on transmission of ultrasonic waves;

memory means for storing the data of said memory card in said microcomputer, said memory means further comprises means for facilitating insertion of another memory card with data to be read out and/or written into said card connector; and

a card interface for data transfer between said memory card and said microcomputer,

wherein diagnosis data is obtained based on both the data from said memory card and the data obtained by the microcomputer.

2. An ultrasonic diagnostic apparatus for ophthalmology as set forth in claim 1, wherein the data of said memory card includes a program and processing data necessary for diagnosis.

3. An ultrasonic apparatus for ophthalmology as set froth in claim 1, wherein the data of the memory card includes measurement data specific to individual patients.

4. An ultrasonic diagnostic method for ophthalmology for transmitting and receiving ultrasonic waves and for outputting a plurality of ultrasonic reflection echo images therefrom, said method comprising the steps of:

inserting and removing a memory card into and from a card connector connected to a microcomputer;

transferring data between the memory card and the microcomputer through the card connector and storing the data of the memory card in memory of the microcomputer so as to facilitate inserting another memory card with data to be read out and/or written; and

obtaining diagnosis data based on data of the memory card and data of the memory of the microcomputer.

5. An ultrasonic diagnostic method for ophthalmology as set forth in claim 4, wherein the data of the memory card includes a program and processing data necessary for diagnosis.

6. An ultrasonic diagnostic method for ophthalmology as set forth in claim 4, wherein the data of the memory card includes measurement data specific to individual patients.
