Description

Technical Field

[0001] The present application relates to the field of image processing technology, and in particular to an image stitching system, method, electronic device and medium. Background Art

[0002] During medical imaging examinations, doctors typically need to enter the scanning room where the imaging equipment resides. They use the control panel to control the scanner's lift, in-and-out position, and activate the external laser light. They then visually observe the location of the laser spot on the patient to achieve initial positioning of the patient. Due to a certain degree of lag in the imaging equipment's response to manual commands, visual positioning accuracy is limited. Furthermore, doctors often rely on experience to estimate the scanning interval during initial positioning, which can lead to problems such as inaccurate positioning, insufficient scanning intervals, and excessive radiation exposure to the patient. Sometimes, doctors must travel back and forth between the operating room and the scanning room several times to complete a series of scans, which is laborious and time-consuming. Lack of hardware support significantly increases the workload of this approach. For example, with some outdated manual displacement microscopes or inconsistent settings of displacement directions and paths between different models of scanning devices, this approach can rely solely on manual sorting, significantly increasing the workload. Furthermore, the stitched images produced by this approach may contain subtle positional discrepancies, affecting image accuracy. Summary of the Invention

[0058] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0059] refer to Figure 1 , Figure 1 1 is a schematic diagram of the framework of an image stitching system provided by an embodiment of the present invention.

[0060] In some embodiments, the diagnostic bed host computer module 100 includes a hand brake switch, and the diagnostic bed host computer module 100 is configured to generate a hand brake switch signal according to a triggering state of the hand brake switch;

[0061] The dynamic flat panel detection module 200 is responsive to the hand brake switch signal to perform image acquisition;

[0062] The high-frequency and high-voltage generator module 300 includes a high-frequency and high-voltage generator and is used to adjust the exposure parameters of the high-frequency and high-voltage generator;

[0063] The image acquisition and processing module 400 is connected to the high-frequency and high-voltage generator module 300, the diagnostic bed host computer module 100 and the dynamic flat-panel detection module 200, and is used to receive stitching instructions, wherein the stitching instructions include a target stitching step number and multiple exposure parameters; perform several image acquisitions according to the stitching instructions until the preset image acquisition conditions are met, and the image acquisition includes: sending one of the exposure parameters to the high-frequency and high-voltage generator module 300, and driving the dynamic flat-panel detection module 200 to perform image acquisition according to the stitching instructions and the hand brake switch signal to obtain a stitched image corresponding to the exposure parameters, wherein the hand brake switch signal is obtained by triggering the hand brake switch in the diagnostic bed host computer module 100; the image acquisition condition is that the current stitching step number reaches the target stitching step number, and the current stitching step number is obtained by counting the number of all image acquisitions that have been performed after each image acquisition; image stitching is performed on all stitched images to generate a target panoramic image, thereby achieving image stitching, improving the accuracy of panoramic image stitching, improving image stitching efficiency, and reducing labor costs.

[0064] In some embodiments, the image stitching system also includes a diagnostic bed lower computer module 500, which is connected to the diagnostic bed upper computer module 100. The diagnostic bed lower computer module 500 is used to drive the diagnostic bed film box to move to a preset stitching position, generate a move-in-place signal, and return the move-in-place signal to the diagnostic bed upper computer module 100, so as to perform the next movement, save manpower operation costs, and achieve precise positioning.

[0065] In some embodiments, the image stitching system also includes a step-by-step photography synchronization module 600, which is connected to the high-frequency and high-voltage generator module 300, the image acquisition and processing module 400, the dynamic flat-panel detection module 200 and the diagnostic bed host module 100. The step-by-step photography synchronization module is used to transmit the hand switch signal, and receive the response signal returned by the dynamic flat-panel detection module 200 and the status signal sent by the high-frequency and high-voltage generator module 300, thereby realizing real-time acquisition and transmission of images and avoiding image delays.

[0066] It should be noted that the status signal is used to indicate the abnormal state of the high-frequency and high-voltage generator module and is used to determine whether the current photographic state is abnormal.

[0067] like Figure 2 As shown, Figure 2 This is a flowchart of an image stitching method of an image stitching system provided by an embodiment of the present invention. The image stitching method is applied to, but not limited to, an image acquisition and processing module in an image stitching system. The image stitching method includes, but is not limited to, step S101 and step S104.

[0068] Step S101: receiving a splicing instruction;

[0069] It should be noted that the stitching instruction includes a target stitching step number and multiple exposure parameters.

[0070] It is understandable that the splicing instruction can be triggered automatically by an operator, an engineer, or the system, wherein the splicing instruction also includes parameters such as splicing direction, operating voltage, and operating mode, which are not specifically limited in this embodiment.

[0071] It is worth noting that the stitching direction can be from head to toe or from toe to head, and the target stitching steps can be set according to the needs of the user. For example, when collecting spine stitching images, the target stitching steps are three steps; when collecting lower limb stitching images, the target stitching steps can be two steps or three steps. This embodiment does not impose any specific restrictions.

[0072] Step S102: performing several image acquisitions according to the stitching instruction. The image acquisition includes: sending one exposure parameter to the high-frequency and high-voltage generator module, and driving the dynamic flat-panel detection module to acquire images according to the stitching instruction and the hand brake switch signal, to obtain a stitched image corresponding to the exposure parameter.

[0073] In some embodiments, image acquisition is performed several times according to the stitching instruction until a preset image acquisition condition is met, thereby obtaining multiple stitched images. In this embodiment, the number of image acquisitions is greater than or equal to two times.

[0074] Step S103: until a preset image acquisition condition is met, the image acquisition condition being that the current number of stitching steps reaches the target number of stitching steps;

[0075] It should be noted that the handbrake switch signal is obtained by triggering the handbrake switch in the diagnostic bed host computer module. The image acquisition condition is that the current stitching step number reaches the target stitching step number. The current stitching step number is obtained by counting the number of all image acquisitions that have been performed after each image acquisition.

[0076] In some embodiments, during the image acquisition process, it is necessary to send an exposure parameter in the stitching instruction to the high-frequency and high-voltage generator module, and drive the dynamic flat-panel detection module to perform image acquisition according to the stitching instruction and the handbrake switch signal, so as to obtain a stitched image corresponding to the exposure parameter, thereby realizing the acquisition of the stitched image.

[0077] It is understandable that the exposure parameters can be set according to the needs of the user. For example, under normal circumstances, the spine splicing program uses the automatic exposure mode of 75-90KV 200ma AEC, and the lower limb splicing uses the exposure parameters of 65-75KV 160ma 80ms.

[0078] It is worth noting that the handbrake switch signal includes a first switch signal and a second switch signal. The first switch signal and the second switch signal stop being sent after the handbrake switch is triggered again, or they also stop being sent during the movement of the diagnostic bed box. Among them, the first switch signal is a signal used to indicate the start of photography, and the second switch signal is a signal used to indicate that exposure is allowed.

[0079] It can be understood that the hand brake switch signal is output by the diagnostic bed host computer module using a relay contact signal after status judgment.

[0080] In some embodiments, if the current number of stitching steps does not reach the target number of stitching steps, step S102 is repeated until the current number of stitching steps reaches the target number of stitching steps, completing the entire image stitching process.

[0081] Step S104: stitching all stitched images to generate a target panoramic image.

[0082] In some embodiments, all the stitched images collected by the dynamic flat-panel detection module are stitched together to generate a target panoramic image, thereby achieving stitching of the entire image step-by-step photography images and improving image stitching accuracy.

[0083] Reference Figure 3 , Figure 3 is a flowchart of an image stitching method provided by another embodiment of the present invention, including but not limited to steps S201 to S202.

[0084] It should be noted that steps S201 to S202 occur before obtaining the stitched image corresponding to the exposure parameters.

[0085] Step S201: sending a splicing instruction to the diagnostic bed host computer module, so that the diagnostic bed host computer module controls the diagnostic bed slave computer module to drive the diagnostic bed slide box to move to a preset splicing position;

[0086] It should be noted that the diagnostic bed host computer module also includes bed control software.

[0087] In some embodiments, before driving the dynamic flat-panel detection module to acquire images, a splicing instruction is sent to the diagnostic bed host module, so that the diagnostic bed host module controls the sending of the splicing instruction to the diagnostic bed lower module, thereby controlling the diagnostic bed lower module to drive the diagnostic bed film box to move to a preset splicing position, and after the diagnostic bed film box moves into place, the diagnostic bed lower module feeds back a moving-in-place signal to the diagnostic bed host module, and the diagnostic bed host module displays the current splicing status through the bed control software. The user or operator can confirm the current splicing status through the bed control software, thereby realizing real-time display of the splicing status, performing positioning confirmation of the patient's position, and avoiding position errors.

[0088] Step S202: receiving a hand switch signal sent by the step-by-step photography synchronization module, and sending the hand switch signal to the dynamic flat panel detection module to switch the working mode of the dynamic flat panel detection module to the photography mode.

[0089] In some embodiments, after triggering the handbrake switch in the diagnostic bed host computer module, the diagnostic bed host computer module will send the handbrake switch signal to the step-by-step photography synchronization module, then receive the handbrake switch signal sent by the step-by-step photography synchronization module, and send the handbrake switch signal to the dynamic flat-panel detection module to switch the working mode of the dynamic flat-panel detection module to the photography mode, thereby facilitating the subsequent image acquisition.

[0090] It should be noted that the working modes of the dynamic flat panel detection module include but are not limited to continuous acquisition mode, photo mode, image playback mode, photography mode, etc., and this embodiment does not impose any specific restrictions.

[0091] Reference Figure 4 In some embodiments, step S102 may include but is not limited to steps S301 to S304:

[0092] Step S301: sending a splicing instruction to the diagnostic bed host computer module, so that the diagnostic bed host computer module sends a hand brake switch signal to the high-frequency high-voltage generator module for presetting and generates a preparation signal;

[0093] In some embodiments, a splicing instruction is sent to the diagnostic bed host computer module so that the diagnostic bed host computer module sends the received handbrake switch signal to the step-by-step photography synchronization module, and the step-by-step photography synchronization module then sends the handbrake switch signal to the high-frequency high-voltage generator module for pre-setting and generates a preparation signal, wherein the pre-setting operations of the high-frequency high-voltage generator module include but are not limited to operations such as anode start-up and filament heating of the high-frequency high-voltage generator, thereby speeding up the speed of image acquisition and improving the efficiency of image acquisition.

[0094] It should be noted that after the step-by-step photography synchronization module receives the hand switch signal, it needs to control the high level or low level to effectively drive the optocoupler to output the signal.

[0095] Step S302: receiving a preparation signal sent by the high-frequency and high-voltage generator module;

[0096] It should be noted that the preparation signal is used to represent the current voltage preparation state and exposure preparation state of the high-frequency and high-voltage generator module.

[0097] In some embodiments, a preparation signal sent by the high-frequency and high-voltage generator module is received, so that the exposure preparation state and voltage preparation state of the high-frequency and high-voltage generator module can be determined, which facilitates subsequent image acquisition.

[0098] Step S303: Sending a preparation signal to the step-by-step photography synchronization module to receive a response signal generated by the dynamic flat panel detection module based on the preparation signal, so that the step-by-step photography synchronization module generates a step-by-step photography exposure signal based on the response signal, controls the high-frequency high-voltage generator module to perform exposure according to the exposure parameters, and controls the dynamic flat panel detection module to perform image acquisition under the exposure parameters to generate a stitched image;

[0099] In some embodiments, a preparation signal is sent to a step-by-step photography synchronization module, so that the preparation signal can be sent to a dynamic flat-panel detection module through the step-by-step photography synchronization module, and a response signal sent by the dynamic flat-panel detection module according to the preparation signal is obtained, and the step-by-step photography synchronization module can generate a step-by-step photography exposure signal according to the response signal, so as to control the high-frequency high-voltage generator module to perform exposure according to the exposure parameters, and control the dynamic flat-panel detection module to perform image acquisition under the exposure parameters, so that images can be acquired under specific exposure parameters and stitching positions, thereby improving the accuracy of image acquisition.

[0100] It should be noted that after the step-by-step photography synchronization module receives the preparation signal, it will send a preparation signal to the dynamic flat-panel detection module. After receiving the preparation signal sent by the step-by-step photography synchronization module, the dynamic flat-panel detection module will first perform operations such as image clearing and cache cleaning, generate a response signal, and send the response signal to the step-by-step photography synchronization module, so that the step-by-step photography synchronization module generates a step-by-step photography exposure signal to control the high-frequency and high-voltage generator module for exposure, and then control the dynamic flat-panel detection module to perform image acquisition under the exposure parameters to generate a stitched image.

[0101] Step S304: receiving the stitched image captured by the dynamic flat panel detection module according to the step-by-step photography exposure signal.

[0102] In some embodiments, the stitched image captured by the dynamic flat panel detection module is received according to the step-by-step photography exposure signal, thereby facilitating subsequent stitching of the stitched image.

[0103] It should be noted that X-ray photons are generated by the high-speed collision of electrons within a high-voltage accelerator tube with the anode target. After penetrating the object being inspected, they undergo a fluorescence effect in the scintillator layer of the dynamic flat-panel detector module and are converted into visible light. The visible light photons are directed by the needle-shaped cesium iodide crystal to the photodiode of the thin-film transistor (TFT) and captured by the electrons therein, generating photoelectrons through the photoelectric effect. The photoelectrons are collected by a collection capacitor and converted into voltage signals by an external electronic circuit, forming a visual digital image. Due to the varying thickness and density of the object being inspected, X-rays undergo a photoelectric effect after passing through the object and are absorbed to varying degrees, forming a latent image. This latent image is ultimately displayed on the digital image as grayscale differences in various parts of the object being inspected. This requires the dynamic flat-panel detector module to perform operations such as image sequence sorting and weighted calibration on the stitched images acquired under the exposure parameters to produce the processed stitched image.

[0104] Reference Figure 5 In some embodiments, step S304 may include but is not limited to steps S401 to S402:

[0105] It should be noted that the image stitching system includes an image receiving module, which is connected to the dynamic flat panel detection module.

[0106] Step S401: receiving an exposure instruction signal sent by a high-frequency and high-voltage generator module;

[0107] It should be noted that the exposure command signal is obtained by the high-frequency and high-voltage generator module by exposing according to the step-by-step photography exposure signal in accordance with preset exposure parameters, wherein the step-by-step photography exposure signal is sent by the step-by-step photography synchronization module to the high-frequency and high-voltage generator module.

[0108] Step S402: The image receiving module is turned on according to the exposure instruction signal, so that the dynamic flat panel detection module uploads the acquired stitched image.

[0109] In steps S401 to S402 of some embodiments, during the process of receiving the stitched image, the exposure instruction signal sent by the high-frequency high-voltage generator module in response to the step-by-step photography exposure signal is first received, and then the image receiving module is turned on according to the exposure instruction signal to prepare for receiving the stitched image captured by the dynamic flat-panel detection module, thereby realizing real-time uploading of the stitched image.

[0110] Reference Figure 6 , Figure 6 4 is a flowchart of an image stitching method provided by another embodiment of the present invention, including but not limited to steps S501 to S502.

[0111] It should be noted that the image stitching system includes a display, and steps S501 to S502 occur before stitching all the stitching images.

[0112] Step S501: performing parameter set processing on the stitched image to obtain a processed stitched image;

[0113] Step S502: Display the stitched image on a display.

[0114] It should be noted that the parameter set processing includes at least one of the following: multi-band local filtering processing; multi-band global filtering processing; contrast processing; background suppression processing; denoising processing; and detail enhancement processing.

[0115] In steps S501 to S502 of some embodiments, after receiving the stitched image sent by the dynamic flat-panel detection module, parameter set processing is performed on the stitched image to improve the clarity of the image, and a processed stitched image is obtained. The stitched image is then displayed on a display and saved in the storage space of a disk to improve the clarity of the image and further improve the accuracy of image stitching.

[0116] It should be noted that, after the current number of splicing steps reaches the target number of splicing steps, this embodiment will also send a splicing end instruction to the diagnostic bed host computer module to end the entire splicing process.

[0117] In order to further illustrate the image stitching method of the above-mentioned image stitching system, a specific example is given below.

[0118] Example 1:

[0119] Example 1 is the specific process of the image stitching method of the image stitching system:

[0120] Step 1: The operator establishes a stitching inspection in the image acquisition and processing module. At this time, the image acquisition and processing module sends a stitching instruction (from head to toe or from toe to head, number of stitching steps, etc.) to the diagnostic bed host module. The diagnostic bed host module sends a stitching movement instruction to the diagnostic bed lower computer module. The diagnostic bed lower computer module controls the diagnostic bed cassette to move to the preset stitching starting position through the diagnostic bed cassette motor. After the diagnostic bed cassette moves into position, it feeds back a moving-in-place signal, and transmits the moving-in-place signal to the diagnostic bed host module through the diagnostic bed lower computer module. The diagnostic bed host module displays the stitching start status through the bed control software for the operator to confirm. At the same time, the image acquisition and processing module sends the first exposure parameter of the step-by-step photography to the high-frequency high-voltage generator, so that the high-frequency high-voltage generator is adjusted to the preset first exposure parameter.

[0121] It is worth noting that the stitching instructions in this example include the target stitching steps, the stitching direction, the first exposure parameter and the second exposure parameter. The target stitching steps are two, and the stitching direction can be stitching from head to toe or from toe to head, etc.

[0122] Step 2: The image acquisition and processing module allows the operator to use the dynamic images captured by the dynamic flat panel to perform step-by-step photography and confirm the patient's position before image stitching begins;

[0123] Step 3: The operator presses the hand switch in the diagnostic bed host module, and the diagnostic bed host module transmits the hand switch signal to the image step-by-step photography synchronization module, wherein the hand switch signal includes a first switch signal Hand I and a second switch signal Hand II. After receiving the first switch signal Hand I, the image step-by-step photography synchronization module transmits the first switch signal Hand I to the image acquisition and processing module in the form of an instruction. The image acquisition and processing module sends a spot mode switching instruction to the dynamic flat panel detection module, instructing the dynamic flat panel detection module to switch from the continuous acquisition mode to the photography mode.

[0124] It should be noted that Hand I means the start of photography, and Hand II means permission for exposure.

[0125] Step 4: The image step-by-step photography synchronization module processes the received handbrake switch signal and transmits it to the high-frequency high-voltage generator. After receiving the handbrake switch signal, the high-frequency high-voltage generator begins preparations for photography.

[0126] It should be noted that the preparation work before photography includes but is not limited to operations such as anode starting and filament heating.

[0127] Step 5: The high-frequency high-voltage generator transmits the current high-voltage preparation state and exposure preparation state to the image acquisition and processing module in the form of instructions. After receiving the preparation signal, the image acquisition and processing module transmits the preparation signal to the image step-by-step photography synchronization module in the form of instructions;

[0128] Step 6: After receiving the preparation signal, the image step-by-step photography synchronization module sends a flat-panel image acquisition request signal to the dynamic flat-panel detection module. After completing image clearing and a series of actions, the dynamic flat-panel detection module returns a response signal of the flat-panel image acquisition request to the image step-by-step photography synchronization module.

[0129] Step 7: After receiving the response signal, the image step-by-step photography synchronization module sends a step-by-step photography exposure signal to the high-frequency high-voltage generator;

[0130] Step 8: After receiving the step-by-step photography exposure signal, the high-frequency high-voltage generator performs exposure according to the preset first exposure parameters and transmits the step-by-step photography exposure signal to the image acquisition and processing module in the form of a command. The image acquisition and processing module opens the image receiving module and begins to prepare to receive the stitched image uploaded by the dynamic flat panel detection module.

[0131] Step 9: The dynamic flat panel detection module sorts, processes, and performs weighted calibration on the spliced ​​images collected by the exposure, and then uploads them to the image acquisition and processing module via the Gigabit network;

[0132] Step 10: After receiving the uploaded stitched image, the image acquisition and processing module processes the stitched image with parameter sets, saves it in the disk storage space, and displays it on the monitor at the same time;

[0133] It should be noted that parameter set processing is to perform multi-band local filtering processing, multi-band global filtering processing, contrast processing, background suppression, denoising, high brightness denoising, high brightness enhancement and detail enhancement on the stitched image.

[0134] Step 11: The image acquisition and processing module sends the second exposure parameter of the second frame of step-by-step photography to the high-frequency high-voltage generator, and at the same time, the image acquisition and processing module transmits the second frame of step-by-step photography instruction to the diagnostic bed host computer module;

[0135] Step 12: The diagnostic bed host module disconnects the hand switch signal transmitted to the image step-by-step photography synchronization module, and at the same time sends a splicing movement instruction to the diagnostic bed lower computer module. The diagnostic bed lower computer module controls the diagnostic bed film box motion system through the motor to move the film box to the preset second splicing position;

[0136] Step 13: After the diagnostic bed cassette motion system detects that the cassette has moved to the preset second splicing position, it stops moving the cassette and returns a motion status instruction to the diagnostic bed host computer module;

[0137] Step 14: The diagnostic bed host computer module transmits the hand switch signal to the image step-by-step photography synchronization module;

[0138] Step 15: Repeat the image stitching method from step 4 to step 10 to capture the second step-stitched image;

[0139] Step 16: Determine whether to perform the third step image stitching according to the stitching step number in the stitching instruction sent by the image acquisition and processing module in the first step;

[0140] Step 17: When it is determined that the current stitching step number reaches the target stitching step number, the acquired stitching images are stitched to obtain the target panoramic image, and the image acquisition and processing module sends an end stitching instruction to the diagnostic bed host computer module to end the entire stitching process.
