Ultrasonic diagnosis equipment for medical purpose

Abstract

A kind of medical ultrasonic diagnosis device, comprises at least the computer and the ultrasonic detecting device; and the local interface is fixed in the ultrasonic detecting device to connect and interact to the computer. The computer transfers control message and exchange the data to the ultrasonic detecting device through the standard interface. The invention has following characteristics: the computer is the main control unit, according to the conjunction of the standard interface and the ultrasonic detecting device, it realizes the high-performance calculation and convenient parameter allocation; the data memories which are used to store the arrangement parameters are fixed in the ejector and the receiver, once the parameters need to change, we can do corresponding set in the computer. set and change the parameters flexible, and adapt to the random change of the probe. The data interface adopts serial design, and the increase number of the probe will not change the whole device, so it realizes the probe's flexible allocation.

Description

technical field [0001] The invention relates to a diagnostic device, in particular to a medical ultrasonic diagnostic device which has a standard bus interface, can be conveniently connected to a computer, and can flexibly set parameters and change the number of probes. Background technique [0002] Acoustic imaging in ultrasound diagnostic equipment is based on the detection of the area of ​​interest in the human body using focused ultrasound pulses. In order to be able to transmit and receive ultrasonic waves, a dedicated ultrasonic probe is required, which can focus the transmitted and received ultrasonic signals at the same time. The area of ​​the body to be studied is scanned within the focal area of ​​this probe. In this case, the ultrasound beams lie in the same plane, either forming a set of parallel lines or forming a fan. [0003] During the detection process, the reflected ultrasonic echo signals are recorded due to the non-uniform internal structure of the rese...

[0015] 2. When the connected probe changes, the delay parameters of the transmitter and receiver should also be changed accordingly; while the parameter settings of the transmitter and receiver of the existing detection equipment are fixed and cannot be changed; and, the existing The transmitter and receiver correspond to the fixed multi-channel circuit one by one, and once the probe is changed, it cannot adapt

[0016] 3. The data interface of the existing ultrasonic detection equipment is usually designed in parallel. Therefore, when the probe is added, the corresponding circuit will be greatly changed, and the flexible configuration of the probe cannot be realized.
