Abstract

The invention discloses a mechanical linear scanning high-frequency ultrasonic diagnosis device, and relates to medical ultrasonic imaging equipment. The mechanical linear scanning high-frequency ultrasonic diagnosis device comprises a mechanical linear scanning probe and a main machine. The mechanical linear scanning probe scans a check part by dragging a high-frequency transducer to do linear reciprocating motion by a stepping motor in the mechanical linear scanning probe through a transmission mechanism; the main machine comprises a control unit, a digital signal processing circuit, an AD array, a high-voltage pulse generating emitter, a transmit-receive switch, a signal amplification circuit, a power drive of the stepping motor in the probe and the like, the control unit enables all parts to work cooperatively, and interaction with an external device is achieved. The effective stroke is long and can reach 70 percent of the external dimension of the probe.

Description

technical field [0001] The invention relates to medical ultrasonic imaging equipment, specifically a mechanical linear scanning high-frequency ultrasonic diagnostic device, which is mainly suitable for superficial organs such as Achilles tendon, breast, skin, and some small organs such as ophthalmology, thyroid, peripheral blood vessels, and testis. , and ultrasound guidance for anesthesia. Background technique [0002] Ultrasonic diagnosis of superficial organs such as animal Achilles tendon, breast, skin, and small organs such as ophthalmology, thyroid, peripheral blood vessels, and testis, as well as ultrasonic guidance of anesthesia are often completed with high-frequency linear array probes. There are high requirements for the detail resolution of the image, but the frame rate of the imaging is not high. The factors affecting the horizontal resolution of the image are related to the spacing of the scanning line beams, that is, to the array element spacing of the probe....
