Abstract
A long-length imaging method based on digital radiography, a digital radiography device, an image processing system and a computer-readable memory medium to implement the method. The long-length imaging method comprises the following steps: A. determining a part of interest of an anatomy of an object; B. determining imaging parameters of digital radiography based on the part of interest, the imaging parameters at least including a plurality of specified positions of imaging components, wherein the plurality of specified positions are configured to capture X-ray images including the part of interest of the anatomy of the object; and C. generating a long-length image in relation to the part of interest of the anatomy of the object based on the captured X-ray images.
Core Innovation
The invention relates to a long-length imaging method based on digital radiography. A part of interest of an anatomy of an object is determined, and a body pose image is generated from an image of the object captured by a camera. The body pose image is suitable to depict the anatomy and highlights key nodes and line segments between the key nodes, where the key nodes indicate bone joints of the anatomy.
The method determines which of the line segments in the body pose image have relevance to the part of interest. Imaging parameters of digital radiography are then determined based on the part of interest and the relevant line segments. The imaging parameters include a plurality of specified positions of an X-ray source and a digital X-ray detector, configured to capture X-ray images of the part of interest at the plurality of specified positions.
A long-length image is generated of the part of interest by stitching together the captured X-ray images from the plurality of specified positions. In the device implementation, an imaging unit including an X-ray source, a camera, and a radiation detector is controlled by a control unit based on the imaging parameters derived by an image processing unit.
Claims Coverage
The partial content includes two independent claims, one covering a long-length imaging method based on digital radiography and one covering a digital radiography device. Both independent claims share the same core sequence of determining a part of interest, generating a body pose image with key nodes and line segments, selecting relevant line segments, deriving imaging parameters with a plurality of specified positions, and stitching captured X-ray images into a long-length image.
Body pose image from captured object image with key nodes and line segments
Generating, from an image of the object captured by the camera, a body pose image suitable to depict the anatomy of the object, the body pose image highlighting key nodes of the anatomy and highlighting line segments between the key nodes of the anatomy, the key nodes of the anatomy indicating bone joints of the anatomy.
Relevance determination of pose line segments for part of interest
Determining which of the line segments in the body pose image have relevance to the part of interest of the anatomy of the object.
Digital radiography imaging parameters with multiple specified X-ray source/detector positions
Determining imaging parameters of digital radiography based on the part of interest and the relevant line segments, the imaging parameters including a plurality of specified positions of an X-ray source and a digital X-ray detector, wherein the plurality of specified positions are configured to capture X-ray images including the part of interest of the anatomy of the object.
Long-length image generation by stitching X-ray images captured at specified positions
Generating a long-length image of the part of interest of the anatomy of the object including stitching together the captured X-ray images captured at the plurality of specified positions.
Device architecture with imaging unit controlled by imaging parameters
A digital radiography device, comprising an imaging unit, comprising an X-ray source, a camera, and a radiation detector as imaging components; a control unit, configured to control an imaging process of the imaging unit based on imaging parameters; and an image processing unit configured to determine a part of interest, generate the body pose image, determine relevance of line segments, determine imaging parameters including a plurality of specified positions, and generate a long length image by stitching the X-ray images.
Across the independent claims, the inventive concept centers on using a body pose image with key nodes and line segments to determine relevant segments for a part of interest, deriving digital radiography imaging parameters that include a plurality of specified positions of X-ray source and detector, capturing X-ray images at those positions, and stitching the captured images into a long-length image.
