Example Embodiment

[0039] Example one

[0040] See figure 1 , figure 1 It is a flow chart of an embodiment of the method of the present invention based on a method of evaluating an ultrasonic probe contact state. like figure 1 As shown, the method includes the steps of:

[0041] S11: Ultrasound information to acquire the morphological response of the subject to different contact states;

[0042] In step S11, the subject refers to any organ that can be imaged in ultrasonic waves. Comparison, biological tissue that can be displayed in ultrasound images or signals include, but not limited to: skin, subcutaneous fat, fascia, ligament, blood vessel, nerve, and muscle, anatomical structure, and bone and specific organs near it. An anatomical structure such as non-soft tissue.

[0043] Wherein, the contact state includes pressure and / or verticality between the ultrasonic probe and the body meter of the subject. When the ultrasonic manner changes from the contact state of the subject, the subject has diff...

Example Embodiment

[0082] Example 2:

[0083] See figure 2 , figure 2 It is a flow chart of the second embodiment of the method of the method of evaluating the contact state of the ultrasonic probe based on the soft tissue form. like figure 2 As shown, the method of the method and the method of the embodiment is also included, further comprising step S27: comparing the forecast value with the preset condition, generates a corresponding instruction based on the instantaneous comparison result. Wherein, step S27 is executed synchronously with step S25.

[0084] The preset condition can be a preset value (ie, single value k), or a preset numerical range (ie, a value of a certain interval k ± K 1constitute). In the specific implementation, according to the relationship between the forecast value calculated by the current frame ultrasound image, the instantaneous comparison result is obtained, determined whether the contact state of the probe satisfies the preset condition, and generates a corresponding ...

[0089] Example three

[0090] See image 3 , image 3 A flow schematic of a third embodiment of the method of the present invention based on a soft tissue format assessed an ultrasonic probe contact state. The application scenario of this embodiment is: the surface of the skin surface is not flat or the object is measured, and the acoustic pad can not only effectively improve the level of the ultrasonic probe and the skin, but also improve the near field resolution. Enhance the quality of imaging. Prior to the implementation of the method of the present embodiment, the operator first places the skin surface of the sonic pad in the subject, and places the hyperpothesis surface of the vocal cushion surface above the subject. like image 3 As shown, the method includes the steps of:

[0091] S31: Ultrasound information to acquire the vocal cushion and the morphological response of the subject to different contact states;

[0092] The difference between step S31 and the embodiment one of...

Abstract

The invention discloses a method and device for evaluating a contact state of an ultrasonic probe based on soft tissue morphology. The method comprises the following steps: S11, acquiring ultrasonic information of a detected object to form responses of different contact states; S12, based on features of the soft tissue in the ultrasonic information and boundary features of the soft tissue, identifying a boundary position of the soft tissue in the ultrasonic information; S13, determining a region of interest and a sampling sub-region in the region of interest based on the boundary position and a preset region division condition; S14, extracting morphological parameters of the soft tissue from the selected region of interest; S15, according to the morphological parameters, calculating a forecast value representing the contact state of the probe by using the at least one soft tissue morphological response; and S16, converting the forecast value into an indication signal which changes along with time. The method and the device are based on an existing ultrasonic imaging equipment, and according to the method and the device, a contact state of a probe can be accurately calculated without changing hardware by adopting a software technical means, and operation of an operator is facilitated.

Description

technical field [0001] The invention relates to the technical field of ultrasonic testing, in particular to a method and device for evaluating the contact state of an ultrasonic probe based on soft tissue morphology. Background technique [0002] Whether it is ultrasonic testing for diagnostic purposes or ultrasonic physical therapy for therapeutic purposes, the contact status of medical ultrasonic probes is an important factor affecting quality control. The contact state usually includes the pressure and perpendicularity between the ultrasonic probe and the surface of the human body. For therapeutic ultrasound, the efficacy depends on the intensity of the ultrasound finally entering the body, which is related to the fit of the probe to the skin. For diagnostic ultrasound, the contact state of the probe can significantly affect the imaging performance and the reliability of the functional measurement results. Especially for quantitative ultrasound, standardized work (ie, m...
