In order to make the technical scheme and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
For simplicity and clarity of description, the invention will be described below by describing several representative embodiments. Numerous details of the embodiments are set forth to provide an understanding of the principles of the invention. It will be apparent, however, that the invention may be practiced without these specific details. Some embodiments are not described in detail, but rather are merely provided as frameworks, in order to avoid unnecessarily obscuring aspects of the invention. Hereinafter, "including" means "including but not limited to", "according to … …" means "at least according to … …, but not limited to … … only". In view of the language convention of chinese, the following description, when it does not specifically state the number of a component, means that the component may be one or more, or may be understood as at least one.
In view of the defect that the medical image in the prior art cannot provide more information, the embodiment of the invention provides a technical scheme for generating a novel medical combined image, wherein the medical combined image comprises a medical image generated by performing medical imaging on an imaging object and a two-dimensional image converted from a three-dimensional image of an imaging object shot by a shooting component, so that the information content in the image can be enriched, and a reader can conveniently grasp a plurality of pieces of information of the imaging object in a multi-dimension manner.
Fig. 1 is a flowchart of a method of generating a medical composite image according to an embodiment of the present invention. Preferably, the method of fig. 1 may be performed by a controller. Wherein the controller may be implemented as or integrated into a control host of the medical imaging system, and may also be implemented as a control unit separate from the control host.
As shown in fig. 1, the method includes:
step 101: a medical image generated by performing medical imaging of an imaging subject with a medical imaging system is acquired.
A medical imaging system performs medical imaging on an imaging subject and may generate a medical image. For example, a medical imaging system may include: a projection X-ray imaging system; an X-ray computed tomography system; a radionuclide imaging system; an ultrasound imaging system; magnetic resonance imaging systems, and the like. Accordingly, the medical image comprises: an X-ray image; a radionuclide image; an ultrasound image; magnetic resonance images, etc.
Step 102: a three-dimensional image generated by photographing an imaging object with a camera assembly is acquired.
In one embodiment, the capture assembly includes at least one three-dimensional camera. The three-dimensional camera photographs an imaging subject using a three-dimensional imaging technique to generate a three-dimensional image of the imaging subject. The three-dimensional camera may be arranged in an examination room in which the imaging subject is located, at any location suitable for photographing the imaging subject, such as on a ceiling, on a floor, or on various components in a medical imaging system, etc.
In one embodiment, the photographing assembly includes at least two-dimensional cameras, wherein each two-dimensional camera is respectively disposed at a predetermined position. In practice, a person skilled in the art can select an appropriate position as a predetermined position to arrange the two-dimensional cameras as necessary. The capture assembly may further include a processor. The processor synthesizes the two-dimensional images captured by the respective two-dimensional cameras into a three-dimensional image of the imaging object, wherein the depth of field adopted by the processor in the synthesis may be the depth of field of any two-dimensional image. Alternatively, each two-dimensional camera may send the respective captured two-dimensional image to a processor outside the capturing component, so that the processor outside the capturing component synthesizes the two-dimensional images captured by the respective two-dimensional cameras into a three-dimensional image of the imaging object, wherein the depth of field adopted by the processor outside the capturing component in the synthesizing process may also be the depth of field of any two-dimensional image. In particular, the processor outside the shooting assembly can be implemented as a control host in the medical imaging system, and can also be implemented as an independent control unit separated from the medical imaging system. Each two-dimensional camera may be arranged in an examination room in which the imaging subject is located, at any location suitable for photographing the imaging subject, such as on a ceiling, on a floor, or on various components in a medical imaging system, etc.
In one embodiment, the photographing assembly may include: at least one two-dimensional camera and at least one depth of field sensor. At least one two-dimensional camera and at least one depth of field sensor are mounted at the same location. The capture assembly may further include a processor. The processor utilizes the depth of field provided by the depth of field sensor in conjunction with the two-dimensional picture provided by the two-dimensional camera to generate a three-dimensional image of the imaged object. Optionally, the two-dimensional camera sends the shot two-dimensional image of the imaging object to a processor outside the shooting assembly, and the depth sensor sends the collected depth of field to the processor outside the shooting assembly, so that the processor outside the shooting assembly generates a three-dimensional image of the imaging object by using the depth of field together with the two-dimensional picture. Preferably, the processor outside the shooting assembly can be implemented as a control host in the medical imaging system, and can also be implemented as an independent control unit separated from the medical imaging system. The two-dimensional camera may be arranged in an examination room in which the imaging subject is located, at any location suitable for photographing the imaging subject, such as on a ceiling, on a floor, or on various components in a medical imaging system, etc.
The above exemplary description describes a typical example in which the image pickup assembly picks up an imaging object to generate a three-dimensional image, and those skilled in the art will appreciate that this description is merely exemplary and is not intended to limit the scope of the embodiments of the present invention.
Preferably, the three-dimensional image may be acquired from the camera assembly in a wired communication manner or a wireless communication manner.
Here, there is no particular requirement on the execution order of step 101 and step 102. For example, step 102 may be performed before step 101, step 102 may be performed after step 101, or step 101 and step 102 may be performed simultaneously.
In step 103: a two-dimensional image of the imaging subject transformed to a predetermined angle is generated based on the three-dimensional image.
Here, with the three-dimensional image acquired in step 102, a two-dimensional image in which the imaging subject is transformed to a predetermined angle is acquired. Wherein the angle is preferably settable. For example, the user may edit the angle via a human-machine interface.
In one embodiment, generating a two-dimensional image of the imaging subject transformed to the predetermined angle based on the three-dimensional image comprises: displaying a three-dimensional image; rotating (for example, rotating along an arbitrary axis in a three-dimensional coordinate system of the three-dimensional image) the imaging object by a predetermined angle in the three-dimensional image; the rotated three-dimensional image is projected onto a predetermined projection plane, thereby forming a two-dimensional image. Preferably, the projected two-dimensional image is a color image. Preferably, the projection surface is configurable. For example, the user may set the projection surface via the interactive interface.
The above exemplary descriptions have been given of typical examples of generating a two-dimensional map of an imaging object transformed to a predetermined angle based on a three-dimensional image, and those skilled in the art will appreciate that such descriptions are merely exemplary and are not intended to limit the scope of embodiments of the present invention.
Step 104: a medically combined image is generated that includes the medical image and the two-dimensional image.
Here, generating the medical combined image including the medical image and the two-dimensional image includes at least one of:
(1) and splicing the medical image and the two-dimensional image into a medical combined image without overlapping.
In such an embodiment, the complete medical image and the complete two-dimensional image together constitute a medical combined image.
(2) And splicing the medical image and the two-dimensional image into a medical combined image in a partially overlapped mode.
In such an embodiment, the complete or partial medical image together with the complete or partial two-dimensional image form a medical combined image.
(3) And adjusting the size of the two-dimensional image, and superposing the two-dimensional image after size adjustment to a region which does not contain the imaging object in the medical image.
In such an embodiment, the two-dimensional image is resized such that the resized two-dimensional image fits into a region of the medical image that does not contain the imaging subject, and therefore the two-dimensional image does not occlude the imaging subject in the medical image.
(4) Cutting out an interested area from the two-dimensional image; and superposing the cut-out region of interest into a region which does not contain the imaging object in the medical image.
In such an embodiment, the cropped region of interest may be highlighted without the region of interest obscuring the imaging subject in the medical image.
In one embodiment, the method further comprises: determining label information; tag information is attached in a region not containing an imaging subject included in a two-dimensional image of the medically combined image.
Therefore, the medical combined image further comprises label information, so that the information content is further enriched. Further, since the label information is added to the two-dimensional image, which is usually in a color format, a distinctive cue effect is also provided. In addition, tag information is attached to a region not containing an imaging subject, and does not interfere with the presentation of the imaging subject. Preferably, the tag information includes: identity information of the imaging subject; imaging information of an imaging subject; shooting information of the medical image; shooting information of the three-dimensional image; a predetermined angle; parameter information of a region of interest of the imaging subject, etc. As can be seen, in the embodiment of the present invention, the label information included in the medical combined image has a variety of rich contents. In particular, by including a predetermined angle in the label information, it is convenient for a reader to quickly understand the two-dimensional image.
The medically combined images of embodiments of the present invention may be packaged in Digital Imaging and Communications in Medicine (DICOM) files that facilitate the exchange of medical image information. For example, a DICOM file may be sent to a picture management and communication system (PACS) for various process analyses.
The following will illustrate embodiments of the present invention by taking X-ray imaging as an example.
X-ray imaging systems typically include: an X-ray generation assembly, a flat panel detector, a chest frame (BWS) assembly and/or a Table assembly and a workstation. The subject stands near the chest frame assembly or lies on the examination table assembly and may be subjected to X-ray radiography of various parts of the skull, chest, abdomen, joints, etc.
Fig. 2 is a first exemplary schematic diagram of generating a medically combined image comprising an X-ray image according to an embodiment of the present invention.
In fig. 2, the X-ray generation assembly, including the X-ray tube 71 and the beam splitter 72, is connected via a support with a telescopic socket 78, the telescopic socket 78 being connected to the ceiling 70. Also, two-dimensional cameras, a two-dimensional camera 73 and a two-dimensional camera 74, are fixed at different positions on the ceiling 70, wherein the shooting directions of the two- dimensional cameras 73 and 74 are both directed toward the imaging subject 75 on the couch assembly 76.
The X-ray generating assembly emits X-rays that are transmitted through the imaging subject 75 and forms X-ray imaging data of the subject on the flat panel detector 90. The flat panel detector 90 sends X-ray imaging data of the imaging subject 75 to the control host via the access point. The control host can be a control host arranged in a local control room, and can also be a remote control host, such as a control host in a cloud. The control host can be a control host arranged in a local control room, and can also be a remote control host, such as a control host in a cloud. The X-ray imaging data is a raw image of the imaging subject 75. In general, such an original image cannot obtain an ideal visual effect, and a variety of image processing methods are required to be performed on the original image to improve the visual effect. For example, the control host performs image processing (e.g., adjusting image contrast, global equalization, and local detail) on the X-ray imaging data (raw image) provided by the flat panel detector 90 to generate an X-ray image suitable for presentation to a user.
The two-dimensional camera 73 and the two-dimensional camera 74 respectively photograph the imaging subject 75 to acquire respective photographed images.
