Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an ultrasonic diagnostic device that performs diagnosis by transmitting ultrasonic waves into a subject and processing the obtained echo signals, particularly a card reading device. The present invention relates to an ultrasonic diagnostic device equipped with the above-mentioned ultrasonic diagnostic equipment.

[Prior Art] In an ultrasonic diagnostic apparatus, the depth from the surface, the type of image desired to be obtained, the gain adjustment value, etc. differ for each subject. For this reason, these data are entered in a medical record or the like, and the knobs of the diagnostic device are adjusted each time the diagnosis is made. Examples of conditions to be adjusted include the following.

■In B-mode ultrasound diagnosis that obtains two-dimensional tomographic images, STC adjusts the echo reception gain, selectively extracts only echoes above a certain value, adjusts the direction, and adjusts the gain according to the depth of the detection position. (sens it 1
adjustment of contrast, adjustment of contrast, etc.

■Adjustment in FTC (fast time constant) processing to clearly extract contours in M-mode ultrasound diagnosis, which displays changes in the distance direction of reflected echoes as a curve.

■Adjustment of pulse repetition frequency (PRF), detection depth (DEPTH), etc. in D mode using pulsed Doppler method.

Conventionally, such conditions are adjusted for each subject and then diagnosed.

[Problems to be Solved by the Invention] In the conventional apparatus, diagnosis can only be performed after adjusting the conditions for each subject using a knob each time. Therefore, the operation is very complicated, it takes a long time to start the diagnosis, and furthermore, if an adjustment is made incorrectly, the adjustment must be made again while checking the result.

[Means for Solving the Problems] In the ultrasonic diagnostic apparatus of the present invention, a card in which setting conditions of the diagnostic apparatus necessary for diagnosis are recorded in advance is inserted, and the data recorded on the card is read. It has a reading device and a control device that automatically sets the conditions of the device according to this data.

[Operation] When making a diagnosis using the ultrasonic diagnostic apparatus of the present invention, first, a card is inserted into the reading device of the ultrasonic diagnostic apparatus. The reader reads the data recorded on the card and sends it to the control device. The control device automatically sets various setting conditions of the ultrasonic diagnostic apparatus using this data. This eliminates the need for the person performing the diagnosis to read the setting conditions from the description in the medical record or the like and adjust the knobs, etc., making the operation easier, faster to start, and more accurate diagnosis.

[Example] Similar to a normal medical examination card, the IC card 10 contains the subject (patient) name, etc., as well as data on how to adjust the ultrasonic diagnostic device when making a diagnosis using the ultrasonic diagnostic device. recorded. For example, B-mode diagnosis, gain value, rejection value, STC processing adjustment value, contrast, etc. are recorded. A card reader 12, which is a reading device, reads data recorded on the IC card 10 when it is inserted.

The device control section 14, which is a control device, receives data read by the card reader 12, processes the data, and supplies a control signal to the device circuit section 16.

The device circuit section is set to each value by this signal, and diagnosis by the diagnostic device 18 is performed.

Here, the keyboard 20 is used for inputting responses to setting values displayed on the CRT 22 as necessary.

Note that the card reader 12 also has a function of writing data to the IC card 10 in response to a signal from the device control section 14.

Next, the operation of this ultrasonic diagnostic apparatus will be explained.

When diagnosing a subject (patient) using an ultrasound diagnostic device, first the IC card 1 for that subject is
0 into the card reader 12 of the diagnostic device 18. Then, the card reader 12 reads the data recorded on the IC card 10.

The read data is sent to the device control section 14, where it is processed and used as operation signals for setting each set value. Then, various setting values of the device circuit section 16 are set by this signal. The diagnostic device 18 then diagnoses the subject.

Here, some of the contents of the IC card 10 are first transferred to the CR.
Displayed on T22. In other words, it includes general information such as subject (patient) name, date of birth, gender, disease name, medical history, and medical history, as well as a list of device settings for previous (and previous) ultrasound diagnoses. If the set value is the same as the previous set value, that effect is input from the keyboard 20, and a signal is output from the device control unit 14. If the user wishes to change the set value, the user inputs a new set value using the keyboard 20 or directly operates the knob to change the set value.

When the diagnosis is completed, the setting values at that time are sent to the IC card using the card reader 12 along with the date of diagnosis, etc.
Write on card 10. This allows the current data to be used during the next diagnosis.

In the above embodiment, only an IC card is used as the card, but the present invention is not limited to this, and other cards such as a barcode card, a punch card, a magnetic card, an optical card, etc. may also be used.

[Effects of the Invention] As described above, according to the ultrasonic diagnostic apparatus of the present invention, data necessary for ultrasonic diagnosis of a subject is recorded on the card, so that the card is not inserted into the apparatus at the time of diagnosis. Simply insert the device and the device will automatically adjust, allowing for quick and accurate diagnosis.
