Probe self-displacement type vertical B-mode ultrasound machine

Abstract

The present invention relates to a probe self-displacement type vertical B-mode ultrasound machine. The B-mode ultrasound machine comprises the following parts: a digital readout circuit is arranged in the vertical B-mode ultrasound machine, connected with a character memorizer and used for dividing 8-bit codes of the character memorizer into two 4-bit codes and sends the codes to a frame memorizer; a D / A converter is arranged in the vertical B-mode ultrasound machine, connected with the frame memorizer of the vertical B-mode ultrasound machine and used for conducting a D / A conversion processing of received signals; in the frame memorizer, image signals in the frame memorizer are mixed with the two 4-bit codes, and the mixed signals are sent to the D / A converter; and a probe displacement device is used to automatically move to a next detection position according to a preset movement trajectory when receiving a first driving command and also used to stay at a current detection positionwhen receiving a second driving command. The probe self-displacement type vertical B-mode ultrasound machine finishes automatic modification of displacement of B-mode ultrasound machine probes.

Description

technical field [0001] The invention relates to the field of B-ultrasound machines, in particular to a probe self-displacement type vertical B-ultrasound machine. Background technique [0002] B-ultrasound machine examination can obtain the sectional images of the organs to be inspected, and can directly observe the morphology, clearly display the structure of the gallbladder and bile duct, and even see the intrahepatic bile duct with a diameter of only 1-2mm, according to automatic measurement The data character display can provide objective data such as the size of the gallbladder and bile duct caliber, the thickness of the tube wall, and the size of the lesion. Therefore, B-ultrasound examination has a high diagnostic value in biliary tract diseases, and B-ultrasound has become the most commonly used method for clinical examination of biliary tract diseases. This method can be used to diagnose gallbladder stones, gallbladder inflammation, tumors, parasites, etc., and has...

Problems solved by technology

[0003] In order to solve the technical problem that the probe displacement of B-ultrasound machines relies heavily on manual operation in the prior art, the present invention provides a probe self-displacement type vertical B-ultrasound machine, on the basis of targeted image processing, using commands to trigger The device is used to measure the number of isolated points in the edge-enhanced image, and when the number of isolated points is greater than or equal to a preset number threshold, a first driving command is issued, and the probe shifting device is used to, when receiving the first driving command, according to The preset movement trajectory automatically moves to the next detection position, otherwise it stays at the current detection position; and in the specific image processing, the reference depth ratio image is introduced to compare the depth ratio of the image after nonlinear processing, and only for the upper left corner area Compare the dark and shallow ratios to effectively save computing resources and reduce device power consumption
