Detailed Description
The following description of the embodiments of the present invention is provided by way of specific examples, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
The first embodiment is as follows:
referring to fig. 1, the present embodiment provides a marker display system for three-dimensional breast ultrasound diagnosis,
comprises a three-dimensional breast ultrasonic diagnosis module and an upper computer;
the three-dimensional breast ultrasonic diagnosis module is used for acquiring an ultrasonic diagnosis image of the breast of a patient, and the ultrasonic diagnosis image comprises a plurality of layers;
the upper computer comprises a layer selection module, a marking module, a mode selection module and a display module;
the display module is used for displaying the ultrasonic diagnostic image;
the layer selecting module is used for selecting a certain layer in the ultrasonic diagnostic image;
the marking module is used for adding marking points on different layers of the ultrasonic diagnostic image;
the mode selection module is used for selecting different image display modes, and when the different image display modes are selected, the display module displays the mark points corresponding to the currently selected image display mode.
Specifically, the method comprises the following steps:
the image display modes selectable by the mode selection module comprise a non-perspective mode, a depth mode, a synchronization mode, a viewpoint forward mode and a viewpoint backward mode.
And under the condition that the mode is not selected, namely under the default condition, the upper computer selects the non-perspective mode.
When the non-perspective mode is selected through the mode selection module, the display module only displays the mark points on the currently selected layer of the layer selection module, and all the mark points of the current layer are displayed as a first pattern. Applicable scenarios: when a doctor needs to specifically observe the mark of a certain layer, the mark of other layers can be filtered by adopting the mode, so that the doctor can concentrate on the diagnosis of the mark of the current layer, the diagnosis efficiency is improved, and the misdiagnosis rate is reduced.
When the perspective mode is selected by the mode selection module, the display module displays the mark points of all the layers, the mark points on the currently selected layer of the layer selection module are all displayed in a first style, and the mark points of the other layers are all displayed in a second style. Applicable scenarios: when a doctor needs to know all the marks under the whole volume in a general way, or when the doctor needs to enter a certain layer quickly, the doctor can enter the layer corresponding to the mark by double-clicking the mark, so that the diagnosis efficiency is improved.
The system also comprises a depth value calculating module which is used for calculating the depth values of all layers, when the depth mode is selected by the mode selecting module, the display module displays all the mark points on the currently selected layer of the layer selecting module, the display module also displays all the mark points on the layer of which the depth value is greater than the depth value of the currently selected layer, and the mark points on different layers are displayed with different display effects according to the depth value of the layer. For example, the following steps are carried out: the display module also displays all the mark points on the layer with the depth value larger than the depth value of the currently selected layer. Further, according to the different depth values of the layers, the display effect of the mark points on each layer of layer will be different, for example, as the depth value is larger, the display of the mark points is smaller; for example, as the depth value is larger, the display color brightness of the mark point is smaller; for example, as the depth value is larger, the mark point display edge generates a fuzzy effect; and so on. It should be noted that the display effect of the mark points on the same layer is the same. Applicable scenarios are: in the diagnosis process, doctors can observe the depth information of the focus in real time, a simple pad is provided for the subsequent treatment scheme, and the diagnosis accuracy is improved.
When the synchronous mode is selected through the mode selection module, the mark points at the same position of the mammary gland of the patient are synchronized in a plurality of ultrasonic diagnostic images of the mammary gland of the same patient, which are acquired through the three-dimensional mammary gland ultrasonic diagnostic module, and are displayed through the display module. That is, if a mark is present at a certain location on one volume, the remaining volumes will also display the mark at the corresponding location, allowing the physician to quickly find a previously marked lesion in another volume in the newly opened volume. In practical operation, although each volume is a scan of a partial region of a unilateral breast, a complete double-breast image can be obtained by mutually overlapping a group of volumes, and all marked lesion information in the volumes is observed in a synchronous mode, so that a diagnosis scene is visual, complete and comprehensive. Applicable scenarios are: when different volumes are observed, the specific shape and size information of the focus can be observed more comprehensively through the mode, and the diagnosis efficiency is improved.
When the viewpoint forward direction mode is selected through the mode selection module, the display module displays the mark points on one surface of the layer relative to the viewpoint forward direction. Applicable scenarios: the method can quickly adjust the direction back to the forward direction of the viewpoint, reduce the operation of adjusting the viewpoint, comprehensively observe the specific shape and size information of the focus, improve the diagnosis efficiency and reduce the misdiagnosis rate.
When the view point reverse mode is selected by the mode selection module, the display module displays the mark points on one side of the layer opposite to the view point reverse direction. Applicable scenarios are: the method can quickly adjust the direction of the focus to the reverse direction, reduce the operation of adjusting the focus, observe the specific shape and size information of the focus more comprehensively, improve the diagnosis efficiency and reduce the misdiagnosis rate.
Referring to fig. 2, each of the modes corresponds to a different algorithm to obtain mark points corresponding to the different modes, and the mark points are displayed by a display module, specifically:
and in the non-perspective mode, a non-perspective algorithm is adopted, the marked data are screened according to the information of the current layer and finally displayed on the image, and only the information of the current layer is displayed on the image.
A perspective mode; and acquiring the information of the current layer by adopting a perspective algorithm, screening the marked data by taking the current layer as a reference, and finally displaying the marked data on an image.
And in the depth mode, a depth algorithm is adopted to obtain the depth values of the whole volume and all layers, the current layer is taken as a reference, the marked data is screened and processed, and finally the marked data is displayed on the image.
A synchronous mode: and (3) filtering all the volumes under the whole inspection by adopting a synchronization algorithm, screening the marked data by taking the current surface as a reference, and finally displaying the marked data on an image.
Viewpoint forward mode: and screening the marked data by adopting a viewpoint forward algorithm and taking the viewpoint forward direction as a reference, and finally displaying the marked data on an image.
View reversal mode: and screening the marked data by adopting a viewpoint reverse algorithm and taking the viewpoint positive direction as a reference, and finally displaying the marked data on an image.
Compared with the prior art, the embodiment selects different modes, and the mark has different presentation effects on the image, as follows:
non-perspective mode: the mutual interference between the vision and the display among the marks of the non-current layers can be eliminated, the influence on the diagnosis is reduced, the diagnosis efficiency is improved, and the misdiagnosis rate is reduced.
Perspective mode: the general situation of all the marks can be known, and the marks of the non-current layer can be selected to quickly enter the corresponding layer, so that the diagnosis efficiency is improved.
Depth mode: the depth information of the mark is known from the image, and the diagnosis efficiency is improved.
