Ophthalmology ultrasonic bio-measurement method

Abstract

The invention discloses an ophthalmology ultrasonic bio-measurement method and relates to the technical field of medical ultrasonic measurement. The method comprises the following steps: storing a digital signal in a programmable logic component; carrying out original code to complementary code calculation on the digital signal to obtain complementary code data; carrying out odd number line frequency reduction, filtering and odd number line frequency rising on an odd number line in the complementary code data successively to obtain processed odd number line data; carrying out even number linefrequency reduction, filtering and even number line frequency rising on an even number line in the complementary code data successively to obtain processed even number line data; carrying out selection, post-filtering, wave detection, logarithm amplification and secondary sampling process on the odd number line data and the even number line data by using an alternative selector; and connecting the selector with a terminal through a USB (universal serial bus) and a periphery circuit so as to display the final image and data. With the adoption of the ophthalmology ultrasonic bio-measurement method, an ultrasonic pulse transmitting voltage is reduced to 12V, so that instantaneous energy output is reduced, omnidirectional imaging of a human body eye tissue is obtained in a lower ultrasonic pulse transmitting voltage is reduced, and precise measurement of a biological tissue is obtained.

Description

technical field [0001] The invention relates to the technical field of medical ultrasonic measurement, in particular to an ophthalmic ultrasonic biological measurement method. Background technique [0002] Clinically, in order to prevent the possible damage to the human body caused by the cavitation effect and thermal effect of ultrasound, the acoustic output power of the medical ultrasound imaging system is strictly limited. parameter requirements. [0003] [0004] * Abdominal, Intraoperative, Pediatric, Small Organ (breast, thyroid, testes, etc.), Neonatal Cephalic, Adult Cephali [0005] It can be seen from the above table that, compared with other tissues and organs of the human body, the special ophthalmic ultrasound imaging equipment has a greater impact on the time-average sound intensity (I SPTA.3 ), pulse average sound intensity (I SPPA.3 ) and mechanical index (MI) and other acoustic output parameters are more stringent. Since the probe of the ultrasonic b...

Problems solved by technology

[0007] In order to achieve lower acoustic output parameters, if the ultrasonic pulse emission voltage is simply reduced, the echo information of the deep orbital tissue will be lost, and the role of panoramic imaging will be lost, which will greatly affect its application in ophthalmology clinical diagnosis value, unable to meet the needs of practical applications
