Referring to fig. 1, fig. 1 is a flowchart illustrating a method for creating a three-dimensional model of a target object according to an embodiment of the present invention. As shown in fig. 1, the method 100 of producing a three-dimensional representation of a target object comprises the steps 101 of: shape data or an image of the target object is acquired. In step 101, shape data or an image of the target object may be acquired by the medical detection apparatus. The medical detection device may be an Ultrasound (US) device, a Computed Tomography (CT) system, a Magnetic Resonance Imaging (MRI) system, a Position Emission Tomography (PET) system, or other medical detection devices known in the art. In some embodiments of the present invention, the two-dimensional shape data, or the two-dimensional image, or the three-dimensional shape data, or the three-dimensional image of the target object may be directly acquired through different operation modes of the medical detection device. In other embodiments of the present invention, the medical detection apparatus may first acquire two-dimensional shape data or two-dimensional images of the target object, and then generate three-dimensional shape data or three-dimensional images of the target object based on a suitable three-dimensional reconstruction method. In other embodiments of the present invention, it is also possible to directly acquire three-dimensional shape data of the target object by the medical examination apparatus and then generate a three-dimensional image of the target object based on the acquired three-dimensional shape data. In step 101 of the embodiment of the present invention, an appropriate shape data type or image type of the target object may be obtained according to specific application requirements. In step 101 of an embodiment of the present invention, a suitable medical test device may be selected according to the needs of a particular application.
In one embodiment of the present invention, the target object may be ultrasonically scanned by an ultrasound device to acquire shape data or an image of the target object. Specifically, the target object may be scanned by emitting ultrasonic waves at different angles by an ultrasonic device to acquire three-dimensional shape data of a region of interest of the target object. A three-dimensional image of the target object may then be generated based on the acquired three-dimensional shape data. During the scanning of the ultrasound apparatus, the shape data of different slices of the target object may be acquired by emitting ultrasound waves of different angles, the acquired shape data of the different slices being formed by the processing unit of the ultrasound apparatus into a data array, which typically consists of a plurality of sets of three-dimensional coordinates distributed at the location of the region of interest of the target object. The three-dimensional coordinates may be provided in DICOM format. Thereby, a three-dimensional image scanned by the ultrasonic device can be acquired.
In some embodiments of the invention, shape data of different modalities of a target object may be acquired by an ultrasound device. In actual operation, the ultrasound device may be configured to perform two-dimensional (2D) ultrasound scanning, three-dimensional (3D) ultrasound scanning, and/or four-dimensional ultrasound (4D) acoustic scanning. The target object may be scanned by the ultrasound device in a corresponding scan pattern to directly acquire shape data of the target object, such as two-dimensional shape data, three-dimensional shape data, or four-dimensional shape data. Alternatively, the ultrasound apparatus may generate a two-dimensional (2D) image, a three-dimensional (3D) image, a four-dimensional (4D) image, and the like through the corresponding scan pattern. Alternatively, a corresponding two-dimensional image, three-dimensional image, four-dimensional image, or the like is generated based on the acquired two-dimensional shape data, three-dimensional shape data, or four-dimensional shape data, for example.
In other embodiments of the present invention, the three-dimensional shape data of the target object may be acquired by other medical detection devices, for example, the three-dimensional shape data of the target object may be acquired by an X-ray detection device, an MR detection device, a CT detection device, or the like. In some embodiments of the present invention, the target object may be scanned in three dimensions (3D) by other medical examination devices mentioned above, such as an X-ray examination device, an MR examination device, or a CT examination device, and a three-dimensional image of the target object is generated based on the acquired volume data set of the target object. For example, three-dimensional shape data of a knee joint, an arm, or a brain bag or the like can be acquired by the MR detection apparatus. A three-dimensional image of the target object may then be generated further based on the acquired three-dimensional shape data of the target object.
The method 100 of producing a three-dimensional representation of a target object further comprises the step 102 of: constructing a three-dimensional model representing the three-dimensional shape of the target object based on the shape data or the image. In step 102, the acquired shape data may be directly input into a three-dimensional model building software to build a three-dimensional model representing the three-dimensional shape of the target object. In step 102, the contour of the acquired image may be extracted by an image processing method based on the acquired image, so as to obtain contour feature points of the target object, and then the feature points are input into three-dimensional model building software, so as to obtain a three-dimensional model representing the three-dimensional shape of the target object.
The method 100 of producing a three-dimensional representation of a target object further comprises the step 103 of: and generating a mold of the three-dimensional shape of the target object by a three-dimensional printing method based on the three-dimensional model. In step 103, three-dimensional (3D) data of the three-dimensional model of the target object may be transmitted to a 3D printing apparatus, and the three-dimensional printing apparatus may then print out a mold of a three-dimensional model of the target object based on the three-dimensional (3D) data of the three-dimensional model of the target object. In an embodiment of the present invention, a three-dimensional modeling mold of the target object may be printed by layer-by-layer printing using a suitable three-dimensional (3D) printing material, such as a bondable material, e.g., metal powder, ceramic powder, gypsum powder, resin powder, plastic powder, or the like. The mold is generally referred to as a mold for casting or a mold for pressing powder, and the shape of the mold corresponds to the contour of the three-dimensional shape of the target object. The mold may have a molding or shaping material (e.g., ceramic, plaster, rubber, plastic, etc.) molded therein. The shape of the mold corresponds to the contour of the three-dimensional model of the target object, and the molding material or the modeling material can be directly poured into the mold to generate the three-dimensional model of the target object.
The method 100 of producing a three-dimensional representation of a target object further comprises the step 104 of: and generating a three-dimensional modeling of the target object by using the mold. In step 104, specifically, the three-dimensional model of the target object may be generated by a suitable method using a mold of the target object, for example, a molding material may be directly poured into the mold, and after the molding material is molded in the mold, the mold may be removed, so that the three-dimensional model of the target object may be obtained. In step 104, the end user (generally, people who need to finally obtain the three-dimensional model of the target object) may actually participate in the process of generating the three-dimensional model of the target object by using the mold, for example, the end user may personally participate in the process of pouring the molding material into the mold, and after the three-dimensional model of the target object is molded, the mold is personally removed to obtain the three-dimensional model of the target object. The participation in the process of producing the three-dimensional representation of the target object is of great and special importance to the end user. For example, if the target object is an embryo, parents are particularly commemorative to parents if they can participate in the process of making a three-dimensional model of an embryo. Moreover, the manufactured embryo model with the three-dimensional model can be stored forever as a souvenir.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for creating a three-dimensional model of a target object according to an embodiment of the present invention. The method 200 of producing a three-dimensional representation of a target object comprises the steps of 201: three-dimensional shape data or a three-dimensional image of the target object is acquired. In step 201, some embodiments of the present invention may perform three-dimensional scanning on a target object by an ultrasound apparatus, thereby acquiring three-dimensional shape data or a three-dimensional image of the target object. In step 201, the target object may be scanned three-dimensionally by other medical detection devices to obtain three-dimensional shape data or three-dimensional images of the target object. The other medical examination apparatus may comprise, for example, an X-ray examination apparatus, an MR examination apparatus, or a CT examination apparatus, among other suitable medical examination apparatuses.
The method 200 of creating a three-dimensional representation of a target object comprises the steps 202: constructing a three-dimensional model representing the three-dimensional shape of the target object based on the acquired three-dimensional shape data or three-dimensional image. In step 202, ultrasonic signals of different angles may be emitted to a target object based on an ultrasonic device, thereby acquiring three-dimensional shape data of the target object, and a three-dimensional model representing the three-dimensional shape of the target object may be constructed based on the acquired three-dimensional shape data.
In step 202, a three-dimensional image of the target object may also be generated based on the acquired three-dimensional shape data by a method of volume rendering. The three-dimensional shape data may include a plurality of voxels of the target object. In step 202, three-dimensional shape data of a target object may be volume rendered using a three-dimensional rendering module of an ultrasound device to generate a three-dimensional image of the target object, and then a three-dimensional model representing the three-dimensional shape of the target object may be constructed based on the rendered three-dimensional image.
In particular, the three-dimensional rendering module of the ultrasound device may render the three-dimensional shape data of the target object into a three-dimensional image by using surface rendering, projection, or other volume rendering techniques. Volume rendering is typically used to render each voxel in the three-dimensional shape data of the target object. The volume rendering includes a defined transfer function to assign a color and an opacity to each voxel of the target object. Thereby, the ultrasonic imaging device can generate and display a rendered three-dimensional image of the target object, and a structural overview of the target object can be obtained.
The method 200 of producing a three-dimensional representation of a target object comprises the steps 203: identifying three-dimensional shape data of the target object or a surface representing a contour of the target object in the three-dimensional image, and constructing a three-dimensional model representing a three-dimensional shape of the target object based on the identified surface. In step 203, a surface representing the contour of the target object may be recognized from the three-dimensional image of the target object based on the three-dimensional image of the target object by the self-contained three-dimensional model creation unit of the ultrasound apparatus, and then a three-dimensional model representing the three-dimensional shape of the target object may be constructed based on the recognized surface. In some embodiments of the present invention, the three-dimensional model of the target object may be constructed by a processing module of the ultrasound device (e.g., a three-dimensional model creation unit of the processing module).
In step 205, a customized modification of a three-dimensional model representing the three-dimensional shape of the target object, which is constructed based on the shape data or image of the target object, may also be performed. Specifically, the original three-dimensional model constructed above may be further customized and modified or perfected according to the requirements or requirements of the terminal customer, and some features that the terminal customer wants to join may be added. Specifically, the modification of the original three-dimensional model of the target object may be included, for example, by changing the shape of the target object, changing a portion of the characteristics of the target object, adding a cartoon character to the target object, or any other modification that can satisfy the end-user's requirements. The terminal client can also participate in the process of customizing and modifying the three-dimensional model, so that the participation degree of the terminal client is increased, and the requirements of the terminal client can be better met.
The method 200 of creating a three-dimensional representation of a target object comprises the steps 204: and generating a mold of the three-dimensional shape of the target object by a three-dimensional printing method based on the three-dimensional model. In step 204, three-dimensional data of the three-dimensional model of the target object may be transmitted to a three-dimensional printing device, which then prints out a mold of the target object based on the three-dimensional data. In an embodiment of the present invention, a mold of the three-dimensional model of the target object may be printed out by layer-by-layer printing using a suitable three-dimensional (3D) printing material, such as a bondable material, e.g., metal powder, ceramic powder, gypsum powder, resin powder, plastic powder, etc.
The method 200 of producing a three-dimensional representation of a target object comprises the steps of 205: and generating a three-dimensional modeling of the target object by using the mold. In step 205, a three-dimensional model of the target object may be generated by injection molding using the mold. Specifically, the injection molding material may be directly injected into a mold generated by 3D printing by using an injection molding process, and after the injection molding material is molded, the mold may be removed, and then the three-dimensional model of the target object may be obtained.
In the embodiment of the present invention, in step 205, in addition to the three-dimensional modeling of the target object may be made by using the mold generated by the 3D printing through the injection molding process, the three-dimensional modeling of the target object may be made by using the mold through other methods.
For example, in some embodiments of the present invention, a molding material may be poured into the mold to create a three-dimensional shape of the target object. For example, a suitable molding material, such as gypsum, resin, wax, etc., may be poured into a mold, and after the molding material is fixed and molded, the mold is removed, and the three-dimensional shape of the target object is obtained.
In step 205, in addition to the above-mentioned two molding methods, the mold may be used to make a three-dimensional model of the target object by some other molding method. For example, the three-dimensional model of the target object can be made by baking using the mold.
In the embodiment of the invention, no matter which method is used for manufacturing the three-dimensional modeling of the target object by using the mold, the terminal user or the terminal client who wants to manufacture the target object can participate in the manufacturing process, so that the participation degree and the experience of the terminal user or the terminal client are improved, and the method has better commemorative significance for the terminal user or the terminal user.
In some embodiments of the invention, the target object is a fetus. In particular, to make a three-dimensional figure of a fetus. The method for making the three-dimensional modeling of the fetus, which is related by the invention, specifically comprises the following steps: acquiring three-dimensional shape data or three-dimensional images of a fetus through an ultrasonic device, and constructing a three-dimensional model representing the three-dimensional shape of the fetus based on the three-dimensional shape data or the three-dimensional images of the fetus. In particular, a surface representative of a surface of the fetus in the three-dimensional shape data or three-dimensional image of the fetus may be identified, and a three-dimensional model representative of the three-dimensional shape of the fetus may then be constructed based on the identified surface of the fetus.
In constructing the three-dimensional model of the fetus, some customized modifications may be made to the three-dimensional model representing the three-dimensional shape of the fetus constructed based on the three-dimensional shape data or three-dimensional image. For example, some customized modifications can be made to the original three-dimensional model constructed as described above according to the needs or requirements of the end customer. The specific modification may include, for example, changing the body shape of the fetus, changing part of the facial features of the fetus, adding a cartoon character to the body shape of the fetus, or any other modification to the original three-dimensional model that can meet the needs of the end-user. The terminal client can also participate in the process of customizing and modifying the three-dimensional model, so that the participation degree of the terminal client is increased, and the requirements of the terminal client can be better met.
