Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
A method, an apparatus, an electronic device, and a storage medium for processing a medical auxiliary image according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a method for processing a medical auxiliary image according to an embodiment of the present invention, and as shown in fig. 1, the method for processing a medical auxiliary image according to an embodiment of the present invention specifically includes the following steps:
s101: a local image of the human body is acquired.
The local image of the human body includes, for example, a local photograph of the human body, a real-time dynamic image of the human body, and a photograph or imaging data of the structure and tissue of the human body, wherein the imaging data of the structure and tissue of the human body may be a DSA (digital assist tomography) image, which includes, but is not limited to, a brain, a liver, a heart, a blood vessel DSA image, and the like. The local part is a part on the human body, such as: head, neck, chest, abdomen, back, buttocks, upper limbs, hands, lower limbs, feet, etc.
The local image of the human body and the real-time dynamic image of the human body can be acquired by a camera of a mobile terminal, and the picture or the imaging data of the structure and the tissue of the human body can be acquired by the camera acquisition or the clinical imaging examination.
S102: and matching a target region corresponding to the local image of the human body in a preset human anatomy model according to the local image of the human body.
As a specific example, for example: firstly, identifying a local image of the human body and key points of the human anatomy model; keypoints in the local image of the human body are then matched with corresponding keypoints in a target region in the human anatomy model.
Specifically, the local image of the human body can be identified by an image identification technology, for example: the identified human body local area is an area surrounded by a rectangular frame. After the human body local area is identified, determining the key points of the body surface anatomical structure of the area, matching the key points with the key points of the corresponding target area of the human body anatomical model so as to match the area corresponding to the human body local area from the human body anatomical model, wherein the area is used as the target area in the human body anatomical model.
In the above description, the human anatomical model includes, but is not limited to: a human anatomical atlas or a human anatomical three-dimensional model. In addition, the preset human anatomy model can be obtained in advance, for example: and acquiring and storing the human anatomy model, wherein the human anatomy model can be obtained by downloading from a server in advance.
S103: the partial image of the human body is mapped with a target region in the human anatomy model, and one of the human anatomy model and the partial image of the human body is displayed on the other of the human anatomy model and the partial image of the human body with a first transparency.
As a specific example, a target region of a human anatomy model is overlaid over a partial image of a human body, and the partial image of the human body is displayed with a first transparency. The first transparency may be preset, and of course, the transparency may also be adjusted according to requirements, for example: the method also includes receiving a transparency adjustment instruction, the transparency adjustment instruction including a target transparency; the first transparency is determined according to the target transparency. Of course, it is also possible to overlay the partial image of the body over the target area of the anatomical model of the body.
That is, according to the matched key points, covering a partial image of a human body on a target area of the human anatomy model, and displaying the partial image of the human body with a first transparency; or according to the matched key points, enabling the target area of the human anatomy model to correspond to the local image of the human body, enabling the human anatomy model to cover the local image of the human body, and displaying the human anatomy model with first transparency.
Wherein the target transparency can be selected from completely transparent to completely opaque, it can be understood that the higher the target transparency setting, the more transparent in the display effect, and conversely, the lower the target transparency setting, the more opaque in the display effect.
For example: the partial image of the human body is set to be semitransparent, so that the partial image of the human body can be displayed on the target area covered on the human anatomy model while the human anatomy model is displayed on the display effect, and the partial image of the human body can be contrasted and referred to.

In one embodiment, as shown in fig. 2, 3 and 4, fig. 2 is a partial color image of a human body with abdominal knife prick, fig. 3 is a schematic diagram of a human anatomy map, and fig. 4 is a schematic diagram of a partial image of a human body with abdominal knife prick displayed in the human anatomy map with a set first transparency after a matched target region in the human anatomy map is mapped to the partial image of the human body with abdominal knife prick. As can be seen from fig. 4, when one patient has pricked the abdomen with a knife and some blood vessel in the abdomen bleeds, it can clearly see which internal organs and blood vessel structures of the patient may be pricked, thereby providing a basis for medical anatomy teaching or clinical diagnosis. If the punctured part of one patient is of a type which is less frequently visited by doctors, the method of the embodiment of the invention can simply and conveniently judge the possibly injured muscles, blood vessels and nerves, thereby providing auxiliary clinical decision for the doctors.
In another embodiment, as shown in fig. 5, 6 and 7, wherein fig. 5 is a DSA image of a blood vessel of an abdomen, fig. 6 is a schematic view of another human anatomy map, and fig. 7 is a schematic view of a DSA image of a blood vessel of an abdomen after mapping the DSA image of a blood vessel of an abdomen on a matching target region in a human anatomy map, and displaying the DSA image of a blood vessel of an abdomen on the human anatomy map with a first transparency set. It is clear from fig. 7 which vascular structures of the patient may be punctured, providing a basis for medical anatomical teaching or clinical diagnosis.
By applying the method of the embodiment of the invention, the camera can be directly aligned to the human body structure, the anatomical structure is presented on the screen, and of course, the presented tissue can be selected, for example, the 'muscle' is selected to be presented, and the muscle appears on the screen, namely: the camera is aimed at the human body, the screen presents local muscle tissues or selects blood vessels, and then the camera presents a blood vessel structure.
According to the medical auxiliary image processing method provided by the embodiment of the invention, not only can students in school doctors be helped to better learn anatomy, but also doctors and the like can simply and conveniently judge structures of possible pathological changes of patients, such as brain, muscle, blood vessels, nerves and the like in clinic, so that reliable auxiliary treatment help is provided for the doctors.
