Measuring method for touch screen ultrasonic diagnosis instrument and touch screen ultrasonic diagnosis instrument

Abstract

The invention discloses a measuring method for a touch screen ultrasonic diagnosis instrument. The method comprises the following steps of: receiving a first touch screen signal, and determining the corresponding touch screen position according to the first touch screen signal; displaying an image in a preset range on the periphery of a touch screen position in a floating zone on a touch screen in an amplified way, and marking a reference cursor corresponding to the touch screen in position in the amplified displayed image; judging whether the first touch screen signal is interrupted or not, if not, changing a reference cursor position in the amplified displayed image according to a touch screen position relation corresponding to the first touch signal until the interruption of the first touch screen signal, and marking the touch screen position on the touch screen when the first touch screen signal is interrupted; and if yes, directly marking the touch screen position on the touch screen when the first touch screen signal is interrupted. According to the measuring method for the touch screen ultrasonic diagnosis instrument, the problem of lower precision by using fingers as input equipment is solved.

Description

technical field [0001] The invention belongs to the field of ultrasonic diagnosis technology, and in particular relates to a measurement method for a touch-screen ultrasonic diagnostic instrument and a touch-screen ultrasonic diagnostic instrument using the method. Background technique [0002] Ultrasonic Diagnosis (Ultrasonic Diagnosis) is a diagnostic method that applies ultrasonic testing technology to the human body. It detects diseases by measuring the data and morphology of physiological or tissue structures. [0003] In the traditional ultrasonic diagnostic instrument equipped with a single display device, the trackball is the main input device in the image detection process, and the trackball needs to be used for various operations such as selection of the measurement menu, positioning of the measurement point, and tracing of the measurement trajectory when measuring the value. . The input of the trackball is continuous. If multiple continuous positioning and select...

AI Technical Summary

Problems solved by technology

[0005] The stylus can provide high precision, but because the doctor needs to hold the probe with one hand and operate the machine with the other hand during the examination of the patient, the stylus is not convenient enough in actual operation

And the touch pen only needs to be used during measurement, and it is not needed in other links of ultrasonic diagnosis, which may cause unnecessary trouble to users

At the same time, additional configurations add unnecessary burdens to cleaning, disinfection and maintenance

[0006] The main problem of finger as an input control device is the low precision. Since the ultrasonic image where the real touch control point is located is covered by the finger itself, the user cannot directly get accurate visual feedback of the control point, which will lead to large marking errors (the source of the error is the finger Contact area), and it is not easy to think of the trackball after touching the touch screen, how can it easily and accurately make any small movements, which cannot well meet the measurement requirements of the ultrasonic diagnostic instrument
