Additionally, in embodiments of the present invention, the term "exemplary" is used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs, unless expressly stated otherwise. Rather, the term using examples is intended to present concepts in a concrete fashion.

In the embodiments of the present invention, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that the intended meaning is consistent when the difference is not emphasized.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order.

First, the terms of art to which the present invention relates will be described:

computed Tomography (CT). CT imaging uses a precisely collimated X-ray beam, gamma rays, ultrasound, etc. and cooperates with a highly sensitive detector to perform cross-sectional scanning around a certain part of the human body and generate a CT image of the cross-section. CT images tend to provide a sharp display of the bone.

Nuclear Magnetic Resonance Imaging (NMRI) is also called spin Imaging, Magnetic Resonance Imaging (MRI), taiwan is also called Magnetic Resonance Imaging, hong kong is also called Magnetic Resonance Imaging, or Nuclear Magnetic Imaging. Nuclear Magnetic Resonance (NMR) imaging is a method of obtaining the position and type of nuclei constituting an object by detecting emitted electromagnetic waves through an external gradient magnetic field according to different attenuations of released energy in different structural environments inside the object by using the NMR principle, and thus, a structural image inside the object can be drawn. The use of this technique for imaging internal structures of the human body has resulted in a revolutionary medical diagnostic tool. The application of the rapidly changing gradient magnetic field greatly accelerates the speed of nuclear magnetic resonance imaging, realizes the application of the technology in clinical diagnosis and scientific research, and greatly promotes the rapid development of medicine, neurophysiology and cognitive neuroscience. Hereinafter, the image of the human body structure drawn by the nuclear magnetic imaging will be referred to as a nuclear magnetic image.

The inventive principle of the present invention is described below:

at present, before a patient is subjected to radiotherapy, in order to determine the position of a lesion and the tissue structure around the lesion, the patient is generally subjected to CT imaging and nuclear magnetic imaging, and then the CT image and the nuclear magnetic image are registered and fused to confirm the soft tissue and the bone structure around the lesion tissue. However, because the imaging principles of the CT image and the nuclear magnetic image are different, the display modes of the generated images are also different, the CT image displays the skeleton clearly, and the nuclear magnetic image displays the soft tissue clearly, so when the tissue around the tumor is determined by using the CT image and the nuclear magnetic image, the CT image and the nuclear magnetic image need to be compared by using the tumor as a reference point through the experience of a doctor, so as to determine the tissue structure around the tumor.

Based on the prior art, according to the technical scheme, the marker is fixed at the preset position on the patient body, so that the position of the marker is displayed on a CT image and a nuclear magnetic image during CT imaging and nuclear magnetic imaging, and then the tissue structures on the CT image and the nuclear magnetic image can be corresponding and overlapped by utilizing the position of the marker on the image, and the fusion and registration accuracy of the image is improved. Further, it is considered that if the marker is fixed to the surface of the human body by means of, for example, adhesion, the problem of the marker being not firmly fixed may occur, which may affect the inspection effect. Because the head of a human body only can move rigidly, the technical scheme provided by the application places the earplug containing the marker in the ear hole by utilizing the ear hole of the human body, so that the position of the marker is shown on a CT image and a nuclear magnetic image during CT imaging and nuclear magnetic imaging. Thus, the ear hole of the human body is a long and narrow channel, so the position of the earplug and the head is easy to fix, and the situation that the marker falls off due to the movement of the patient can be avoided as much as possible in the ear of the earplug, so the earplug is easy to use.

The first embodiment is as follows:

based on the inventive principles described above, an earplug 1 according to an embodiment of the invention includes an earplug body 11 and a tag 12, as shown in fig. 1. Wherein the marker 12 is disposed at a preset position of the earplug body 11. The earplug body 11 can be made of a material with good compatibility with human skin to improve the comfort of users and ensure that the earplug is not easy to move when in use.

As shown in fig. 2, due to the different imaging principles of CT images and nuclear magnetic images, the markers 12 include at least two types of CT markers 12a (shown in fig. 2a) and nuclear magnetic markers 12b (shown in fig. 2 b). Wherein the CT marker 12a is capable of forming a first marker pattern in a CT image and the nuclear magnetic marker 12b is capable of forming a second marker pattern in a nuclear magnetic image.

Specifically, in practice, one type of marker may be fixedly placed at a predetermined position of the earplug body 11, for example, the CT marker 12a is fixedly placed in one set of earplugs, and the nuclear magnetic marker 12b is fixedly placed in the other set of earplugs. In use, one of the two sets of earplugs may be selected for wearing based on whether a magnetic resonance examination or a CT examination is being performed by a user to form a pattern of indicia in an examination image. In addition, a replaceable marker can be arranged at a preset position in the same earplug, and a user can directly replace the marker in the earplug according to different examinations without replacing the earplug.

Specifically, in one implementation, the marker 12 is fixedly disposed at a predetermined position of the earplug body 11. So that the user forms a pattern of marks in different inspection images by wearing different earplugs.

Further, when the markers 12 are fixedly disposed at the preset positions of the earplug body 11, in order to ensure that the positions of the different types of markers are the same in the ear canal of the user, in the embodiment of the present invention: the earplug bodies provided with the different types of markers have the same shape, and the different types of markers are respectively provided at the same positions of the corresponding earplug bodies.

In another implementation, if the same earplug body is used to form the mark patterns on the CT image and the nuclear magnetic image, the possibility of the position of the mark being changed due to earplug replacement can be avoided as much as possible, and the convenience of use can be improved. In the embodiment of the present invention, as shown in fig. 3, the outer end of the earplug body 11 is further provided with an opening 111, and the marker 12 can be taken out from the preset position of the earplug body 11 through the opening 111, or the marker 12 can be placed at the preset position of the earplug body 11 through the opening 111. In embodiments of the invention, the tag may be removed or placed in the earplug body through an opening provided in the earplug body. Thereby effecting replacement of the marker.

In another implementation, the marker 12 in embodiments of the present invention may be configured as a sphere to facilitate the placement and placement of the marker 12.

In another implementation, as shown in FIG. 4, to ensure that the marker 12 does not move within the earplug body 11, the earplug body 11 in the present embodiment further includes an auxiliary structure 112 for fixing the marker 12 at a predetermined position. It should be noted that fig. 4 only shows an exemplary structural schematic diagram of the auxiliary structure 112, and those skilled in the art may also adopt other structural forms of auxiliary structures according to specific needs in practical application, so as not to limit the present invention.

In another implementation, as shown in FIG. 5, to facilitate removal of the tag 12 from the earplug body 11, the tag 12 includes a pull wire 121 thereon.

In another implementation, the CT markers 12a may be a high density material for forming a marker pattern on a CT image during CT examination. For example, the CT marker 12a may be made of a metallic material. The nuclear magnetic marker 12b may be a substance containing H ions and arranged in a predetermined direction under a magnetic field, and is used to form a marker pattern on a nuclear magnetic image during nuclear magnetic examination. For example, water or an aqueous substance such as copper sulfate may be used.

In another implementation, the outer end of the earplug body 11 is thicker than the inner end of the earplug body, and the outer end of the earplug body 11 may be configured to conform to the pinna of a human body, as shown in fig. 1-5, for comfort of wearing and robustness of the earplug.

In the embodiment of the invention, the outer end of the earplug main body is thicker and is attached to the auricle of a human body, so that the length of the earplug entering the ear canal can be fixed, and the phenomenon that the comfort degree of a user is influenced when the earplug excessively enters the ear canal can be avoided.

It should be noted that, for convenience of description in the embodiments of the present invention, one end of the earplug body entering the ear canal of a human body is referred to as "inner end", and the other end is referred to as "outer end", and the terms are only used for describing the structure of the earplug and do not limit the function of the earplug body.

Fig. 6 is a schematic view of an earplug 1 according to an embodiment of the invention, wherein one end of the earplug body entering the ear canal of a human body is referred to as an "inner end" and the other end is referred to as an "outer end". The outer end of the earplug body 11 is thicker than the inner end of the earplug body and the outer end of the earplug body is arranged to be attached to the auricle of a human body.

Example two:

an embodiment of the present invention further provides an image processing method, as shown in fig. 7, the method includes:

s201, a CT image including the first mark pattern generated when the user wears the earplug provided in the first embodiment is obtained.

Wherein the marker comprised by the earplug is a CT marker. The first marker pattern refers to a marker pattern formed by a CT marker in a CT image.

Specifically, in an implementation manner, in order to ensure fusion and registration of the CT image and the nuclear magnetic image, an earplug including a CT marker may be worn in each of the left and right ears by a user during a CT examination, and then CT images including two first marker patterns generated when the left and right ears of the user wear the earplugs are obtained.

S202, a nuclear magnetic image including the second mark pattern generated when the user wears the earplug provided in the first embodiment is obtained.

Wherein the tag included in the earplug is a nuclear magnetic tag. The second marker pattern refers to a marker pattern formed by the nuclear magnetic marker in the nuclear magnetic image.

Specifically, in a similar way to the above CT image acquisition, in an implementation manner, when performing nuclear magnetic examination, a user can wear one earplug including a nuclear magnetic marker in each of the left and right ears, and then nuclear magnetic images including two second marker patterns generated when the left and right ears of the user wear the earplugs respectively are acquired.

And S203, registering the CT image and the nuclear magnetic image according to the position of the first marker pattern in the CT image and the position of the second marker pattern in the nuclear magnetic image.

The registration may be to overlap the CT image and the nuclear magnetic image, and the treatment physician may confirm the positional relationship between the tumor and the surrounding tissue according to the registered display image by adjusting the transparency or adjusting different regions to display different types of images.

Of course, the registered images may also be derived and combined into one image. In one implementation manner, the method provided by the embodiment of the present invention further includes: and synthesizing the CT image and the nuclear magnetic image into a body structure image. The body structure image includes both the information in the CT image and the information in the nuclear magnetic image. The specific form and manner of image registration are not limited in the present application, and the above example is only used for illustration.

Specifically, for example, as described in the above steps S201 and S202, CT images and nuclear magnetic images generated when the left and right ears of the user are both worn with the ear plugs are acquired. The CT image may be registered with the nuclear magnetic image using the locations of the two first marker patterns in the CT image and the locations of the two second marker patterns in the nuclear magnetic image.

Of course, the image fusion registration by the marking pattern on one side may be performed by only one ear, and the fusion accuracy may be inferior compared with the case of wearing both ears.

The image processing method provided by the embodiment of the invention can fuse the CT image and the nuclear magnetic image by utilizing the marking patterns formed on the CT image and the nuclear magnetic image by the marker in the earplug so as to accurately position the position of the focal tissue.
