Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, a template measurement system for preoperative imaging includes the following steps: step one, acquiring and importing image data, and selecting related pictures from a picture shooting or equipment picture library; correcting the image, eliminating the deformation of the image and recovering the original size of the image; step three, proportion measurement, namely inputting a known size, converting the magnification of the picture by a system, and locking by the system; determining and measuring anatomical landmarks, namely determining and marking the anatomical landmarks on the picture, measuring data of the picture, and storing and exporting the picture data obtained by system measurement; step five, measuring the template, importing the electronic template, adjusting the magnification of the electronic template to be consistent with the magnification of the picture, locking the electronic template by the system, measuring data of the electronic template, and storing and exporting the electronic template data measured by the system; and step six, forming a measurement report, storing the measurement report and uploading the measurement report to a server. Through the design, the invention provides a template measuring system for preoperative images, and measurement reports are formed through the system in the processes of identifying, correcting, setting proportion, measuring a template and the like of a measurement picture, so that not only can medical staff estimate and plan the size of a prosthesis required to be used in the operation conveniently, the operation precision is improved, the occurrence of complications is reduced, but also the academic communication between patient data management and the medical staff is facilitated.
And step two, identifying four corners of the picture through the system, taking the four corners of the picture as the four corners of the rectangle, and stretching the picture into the rectangle through the system. After the system identifies the four corners of the picture, corner marks are carried out on the four corners of the picture, a user can re-determine the four corners of the picture by modifying the positions of the corner marks, and after the user confirms to click the next step, the picture is stretched into a rectangle through the system.
In the third step, the proportion is measured by placing a marker when the picture is taken or by a scale carried by the picture. Placing a marker when a picture is shot, inputting the known size of the marker by a user, and converting the magnification of the picture by a system; or, the user directly inputs the scale size of the known picture and the magnification of the picture is converted by the system. The picture is locked through the system, so that a user is prevented from modifying or dragging the picture, and the picture is convenient to compare with the electronic template subsequently.
And in the fourth step, determining anatomical landmarks on the picture and forming anatomical landmark marks, wherein the anatomical landmark marks are fixed at corresponding positions of the picture. Anatomical landmark markers include acetabular rotation center, medullary cavity center line, and the like. The points or lines marked by the anatomical landmarks cannot be dragged, so that the subsequent prediction or planning inaccuracy is avoided. The user may cancel the last marked anatomical landmark by a dismissal operation. The user can select the required measurement data through the system according to the anatomical landmark marks, and the system can measure the angle and the size of the bony structure on the picture. The measured picture data comprises a shaft angle, a femoral head eccentricity, a femoral head height, an acetabulum valgus angle and the like.
In the fourth step, when the user performs the hand operation on the picture, the system displays the amplification effect picture of the hand operation area on one side of the hand operation area of the user in real time. For example, the user identifies anatomical landmark markers by hand manipulation. The user can display the finger operation area near the user through the magnifier, so that the finger can be prevented from being shielded to influence the operation.
And step five, after the electronic template corresponding to the picture is imported, the user can adjust the position and the size of the electronic template through dragging and modifying, the comparison with the picture is convenient, the electronic template is locked after the adjustment is finished, and the position of the electronic template is prevented from being dragged again. And the system selects measurement data and measures the angle and the size of the bony structure on the electronic template. The measured data of the electronic template comprises a shaft angle, a femoral head eccentricity, a femoral head height, an acetabulum valgus angle and the like. The image data and the electronic template data are convenient to compare.
And step five, when the user performs hand operation on the electronic template, the system displays the amplification effect picture of the hand operation area on one side of the hand operation area of the user in real time. For example, the user repeatedly determines the anatomical landmark markers matching the positions on the picture by hand manipulation. The user can display the finger operation area near the user through the magnifier, so that the finger can be prevented from being shielded to influence the operation.
And step six, the user sends the measurement report to friends or workgroups in the system for sharing. The user adds friends or participates in the working group in the system to transmit characters, voice and files, and the preoperative planning and the academic communication among medical personnel are facilitated. The user applies for an individual account in the system, and the user can make, upload, view or export a measurement report through the authority of the individual account. Before uploading to the server, the user modifies the privacy state of the measurement report, so that the case privacy is protected or the measurement report is shared by a working group or designated individuals.
Through this design, medical staff has been changed and has been followed to select the prosthesis specification or directly plan before doing on the X-ray film by virtue of the operation experience, discern the measurement picture through this system, correct, the proportion is set for, the template is measured, process such as partial data to bony structure measures, and then make medical staff convenient, accurate, safety, and the efficient predicts and plans the prosthesis size that needs to use in the art, improve the operation precision and reduce the emergence of complication, plan before the accurate art can guarantee to implant suitable prosthesis, guarantee operation effect, reduce the operation time, reduce the collateral damage, and be favorable to patient's postoperative quick recovery.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the invention as defined by the appended claims. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
