Embodiment 1

[0048] This embodiment provides an internal body interventional sector scan probe 1 with rotational positioning, such as figure 1 As shown, an ultrasonic mechanism 11 and a calibration mechanism 12 are included.

[0049] Such as figure 1 and figure 2 As shown, the ultrasonic mechanism 11 includes a housing 111 , a servo motor 112 and an ultrasonic transducer 113 . The casing 111 is a tubular shell with one end closed, and the cavity formed by the tubular shell is used to accommodate the ultrasonic transducer 113 .

[0050] In order to avoid the error caused by the servo motor in the prior art when the ultrasonic transducer is driven by a flexible shaft, the hardness of the transmission material and the transmission distance can be improved. For example, the servo motor 112 and the ultrasonic transducer 113 are transmitted through a hard material. , such as shortening the transmission distance between the two, etc., can effectively eliminate the transmission error. Specifi...

Embodiment 2

[0070] This embodiment provides an imaging system, such as Figure 9 As shown, the internal body interventional sector scan probe 1 and the imaging host 2 provided by Embodiment 1 are included.

[0071] The imaging host 2 is provided with a control module, which is respectively connected to the servo motor 112, the ultrasonic transducer 113, the sensor 121, and the sensor 122 through wired or wireless communication to provide power supply, data collection and other functions; in this embodiment, wired way of communication.

[0072] The control module is also connected to the display of the imaging host 2 by wired or wireless means, displays the information collected by the ultrasonic transducer 113 in the form of an image, and calibrates the information collected by the sensor 121 and the sensor 122 before synthesizing the image. Judging the actual direction switching position and sector scanning angle of the ultrasonic transducer 113 will not cause image distortion during im...

Abstract

The invention belongs to the technical field of ultrasonic imaging, and particularly relates to an in-vivo intervention fan-shaped scanning probe with a rotary positioning function and an ultrasonic imaging system comprising the in-vivo intervention fan-shaped scanning probe. The in-vivo intervention fan-shaped scanning probe comprises an ultrasonic mechanism and a calibration mechanism; the ultrasonic mechanism comprises a shell, an ultrasonic transducer and a servo motor, wherein the shell is provided with a containing cavity, and the ultrasonic transducer and the servo motor are arranged inthe containing cavity together; and the calibration mechanism comprises a sensor and an inductor which are oppositely arranged on the shell and the ultrasonic transducer. When the ultrasonic transducer performs fan-shaped scanning motion relative to the shell, the inductor or the sensor can be used as an interval calibration unit to acquire signals or give signals, and accordingly the angle of the ultrasonic transducer performing fan-shaped scanning motion relative to the shell and the position of the ultrasonic transducer during direction switching are obtained. An imaging host can realize fan-shaped scanning motion positioning of the ultrasonic transducer through the position and the angle acquired by the calibration mechanism, so that the problem of distortion during image synthesis isavoided.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic imaging, and in particular relates to an in vivo interventional sector-scan probe with rotational positioning and an ultrasonic imaging system comprising the same. Background technique [0002] When diagnosing body cavity lesions, there are certain subjectivity and limitations in inferring purely from the changes in tissue surface morphology. In vivo interventional ultrasound imaging technology uses ultrasonic probes to intervene in the body to scan blood vessels, digestive tract, bronchus, heart and other tissues in the body, and can obtain relatively clear and accurate tomographic images of internal tissues, providing doctors with an objective basis for symptomatic treatment. in accordance with. [0003] An in vivo interventional ultrasound imaging device generally includes an imaging host, an in vivo interventional ultrasound probe, and an external drive control unit. The rotational motion ...
