Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular, to a data acquisition method and system. Background Art

[0002] During the operation of the optical coherence tomography (OCT) scanner, the scanning galvanometer controller controls the deflection of the scanning galvanometer so that the emitted laser beam scans different positions of the eye. The detector collects the light signal returned by the eye, and the data acquisition card obtains the output signal of the detector. The host computer then reads and analyzes the output signal of the data acquisition card, thereby realizing eye detection.

[0003] The scanning of the eyes is done by sending scanning sequences to the scanning galvanometer controller through the host computer, so that the scanning galvanometer executes scanning sequences to scan different positions of the human eye, and the data acquisition card obtains the scanning data corresponding to each scanning sequence. If the eye moves during the scanning process, it needs to be rescanned. Since there is no strict synchronization mechanism between the scanning galvanometer controller and the data acquisition card, the host computer can only reset the scanning galvanometer controller and the data acquisition card, and both sides remain in the initial state, and then the host computer sends new scanning sequences to the scanning galvanometer controller, and at the same time starts the data acquisition card, in order to maintain data synchronization. This method requires interrupting the current data acquisition and resetting the scanning galvanometer controller, and the scanning efficiency is low. Summary of the invention

[0046] The present disclosure is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present disclosure, but are not intended to limit the present disclosure in any form. It should be noted that, for those of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present disclosure. These all fall within the scope of protection of the present disclosure.

[0047] Figure 1 The figure is a flow chart of a data acquisition method according to an exemplary embodiment. Figure 2 The figure is a schematic diagram of a data acquisition process according to an exemplary embodiment.

[0048] like Figure 1 , Figure 2 As shown, the present disclosure provides a data acquisition method, comprising:

[0049] S11, obtaining a scanning protocol for scanning the object to be measured.

[0050] The scanning protocol includes a scanning sequence set, and each scanning sequence in the scanning sequence set has a corresponding scanning sequence number.

[0051] like Figure 2 As shown, in the present disclosure, PC (Personal Computer) represents a host computer, Lineparameter represents a scan sequence, Sn represents a scan sequence number, Btrig represents a scan control signal, and Atrig represents a sub-scan control signal.

[0052] For example, a scanning protocol for scanning the object to be detected can be obtained from a PC, wherein the scanning protocol includes a scanning sequence set, and a unique scanning sequence number is encoded for each scanning sequence to form a scanning protocol for scanning the object to be detected.

[0053] During the operation of an optical coherence tomography (OCT) device, a PC sends a scanning protocol to the OCT, specifically, to a scanning galvanometer controller of the OCT. Each scanning sequence in a scanning sequence set in the scanning protocol corresponds to a scanning sequence number.

[0054] S12, taking the scanning sequence set as a target scanning sequence set, scanning the object to be measured according to the target scanning sequence set, and determining scanning data.

[0055] Continuing with the above example, according to the target scanning sequence set sent by the PC, the OCT performs an operation of scanning the object to be measured to obtain scanning data.

[0056] S13, obtaining a scan data packet corresponding to each scan sequence in the target scan sequence set.

[0057] The scanning data packet includes a scanning sequence number corresponding to the scanning sequence and scanning data.

[0058] Continuing with the above example, the data acquisition card obtains the scan data packet through sampling operation.

[0059] Through the above technical solution, a scanning sequence number is set in the scanning sequence set, and each scanning sequence has a unique corresponding scanning sequence number. In the process of the scanning galvanometer controller performing scanning according to the scanning sequence, since the scanning sequence has a corresponding scanning sequence number, the scanning data packets sampled and packaged by the data acquisition card have a one-to-one correspondence with the scanning sequence and the scanning sequence number, thereby improving the stability and reliability of the control process.

[0060] In a possible embodiment, S12, taking the scanning sequence set as the target scanning sequence set, scanning the object to be measured according to the target scanning sequence set to determine the scanning data, may also include S21 to S23.

[0061] S21, performing update processing on the scanning sequence set according to a preset rule to determine an updated scanning sequence set.

[0062] In the present disclosure, the preset rule is: when the object to be detected moves, the scanning sequence set is updated; or when a lesion area is found during scanning, the scanning sequence set is updated.

[0063] In a possible embodiment, if the object to be detected moves, the scan sequence in the scan sequence set is updated to determine a new scan sequence, each new scan sequence having a corresponding new scan sequence number; an updated scan sequence set is determined based on the new scan sequence and the new scan sequence number.

[0064] The situation where the object to be detected moves may include: during the eye scanning process, the eyeball or the head moves.

[0065] The scan sequence with the updated scan sequence number is a new scan sequence.

[0066] In another possible embodiment, when a lesion area is found during the scanning process, each scanning sequence in the scanning sequence set is updated to a new scanning sequence, and the scanning sequence number corresponding to each scanning sequence is updated to the new scanning sequence number to determine an updated scanning sequence set.

[0067] S22: Use the updated scanning sequence set as the target scanning sequence set.

[0068] Each new scanning sequence in the updated scanning sequence set has a corresponding new scanning sequence number.

[0069] S23, scanning the object to be measured according to the target scanning sequence set to determine scanning data.

[0070] Continuing with the above example, if the object to be measured moves, for example, the eyeball moves when scanning the eyes, the updated scanning sequence set is used as the target scanning sequence set to scan the object to be measured, and the latest scanning data of the object to be measured is obtained to prevent the scanning data from being less accurate due to the movement of the object to be measured, thereby affecting subsequent data processing.

[0071] Continuing with the above example, when a lesion area is found during the scanning process, the updated scanning sequence set is used as the target scanning sequence set to scan the lesion area again, and the two scanning data of the lesion area are obtained and compared to determine whether the area is a lesion area, thereby improving the accuracy of the scanning data and providing more scanning data for the lesion area to help diagnose the lesion.

[0072] Through the above technical solution, when the object to be measured moves or a lesion area is found, there is no need to reset the scanning galvanometer controller and the data acquisition card, and there is no need to interrupt the data acquisition work. By updating the scanning sequence set to a new scanning sequence and a new scanning sequence number, and using the updated scanning sequence set as the target scanning sequence set, the scanning data packet is obtained, and the scanning data is filtered according to the scanning sequence number to obtain valid data, thereby improving the operating efficiency of the scanning equipment.

[0073] In a possible embodiment, the method for determining whether the object to be detected has moved may include S31 to S33.

[0074] S31, acquiring a target image and a reference image obtained after scanning the object to be measured.

[0075] As an example, at least one of a pupil camera, a fundus camera, an optical coherence tomography scanner, and a confocal scanning system ophthalmoscope (CSSO) can be used to image the object to be measured to determine a reference image and a target image.

[0076] The imaging time of the reference image is earlier than the imaging time of the target image.

[0077] The reference image may be an image of the object to be measured at an initial moment, or an image of a historical moment separated from the current moment by a preset time threshold, or an image of any historical moment earlier than the imaging time of the target image.

[0078] S32, determining the displacement of the object to be measured according to the target image and the reference image.

[0079] As an example, the target image and the reference image are compared to determine the displacement of the object to be measured. This embodiment does not limit the method for calculating the displacement, and methods such as template matching, feature matching, scale-invariant feature transform (SIFT), and fast nearest neighbor search algorithm (FLANN) can be used to determine the displacement of the object to be measured.

[0080] S33, determining whether the object to be detected moves according to the displacement and a preset displacement threshold.

[0081] As an example, if the displacement is less than a preset displacement threshold, it is determined that the object to be detected has not moved.

[0082] As another example, if the displacement is not less than a preset displacement threshold, it is determined that the object to be detected has moved.

[0083] In a possible embodiment, if the object to be measured moves, the target scanning position is determined according to the displacement and the current scanning position.

[0084] As an example, if the displacement of the object to be measured is -0.1mm and the current scanning position is 1mm, the target scanning position is 1+(-0.1)=0.9mm. The scanning sequence set is updated according to the target scanning position, and the starting scanning position of the updated scanning sequence set is 0.9mm. The scanning galvanometer controller continues to scan the object to be measured from the starting scanning position of 0.9mm according to the updated scanning sequence set.

[0085] Through the above technical solution, by comparing the reference image and the target image, it is determined whether the object to be measured has moved, and a judgment is made as to whether the scanned data set is updated, thereby improving the accuracy of data scanning and data processing.

[0086] In a possible embodiment, scanning the object to be detected according to the target scanning sequence set to determine the scanning data may include:

[0087] According to each scanning sequence in the target scanning sequence set and the scanning sequence number corresponding to each scanning sequence, a scanning control signal encoded with the scanning sequence number is generated.

[0088] The object to be measured is scanned according to the scanning control signal encoded with the scanning sequence number to determine the scanning data.

[0089] As an example, a corresponding initial scan control signal is generated according to each scan sequence in the target scan sequence set sent by the PC, wherein the initial scan signal represents an uncoded scan control signal.

[0090] Each scanning sequence includes a group of scanning line beams, and within the effective acquisition time of the initial scanning control signal, a group of scanning line beams completes scanning of the object to be measured.

[0091] Specifically, the OCT scans the object to be measured according to the initial scanning control signal. During the scanning process, the scanning sequence number corresponding to each scanning sequence is encoded into the initial scanning control signal to generate a corresponding scanning control signal encoded with the scanning sequence number. The OCT then continues to scan the object to be measured according to the scanning control signal encoded with the scanning sequence number to obtain scanning data.

[0092] The effective acquisition time of the initial scanning control signal and the scanning control signal encoded with the scanning sequence number is the same, and the effective acquisition time is the time for scanning the object to be measured.

[0093] As another example, before scanning the object to be measured, a scanning control signal encoded with a scanning sequence number is generated according to each scanning sequence and the corresponding scanning sequence number in the target scanning sequence set sent by the PC. The OCT scans the object to be measured according to the scanning control signal encoded with the scanning sequence number to obtain scanning data.

[0094] In the present disclosure, the scanning galvanometer controller performs scanning of the object to be measured according to a scanning control signal encoded with a scanning sequence number.

[0095] In a possible embodiment, generating a scanning control signal encoded with a scanning sequence number includes:

[0096] Within the effective acquisition time of all sub-scanning control signals corresponding to each scanning sequence, all bytes of the scanning sequence number are encoded onto the initial scanning control signal to generate a scanning control signal encoded with the scanning sequence number.

[0097] Each scanning sequence corresponds to a plurality of sub-scanning control signals.

[0098] Specifically, each scanning sequence includes a group of scanning line beams, and each scanning line beam is controlled by each sub-scanning control signal. Within the effective acquisition time of each sub-scanning control signal, each corresponding scanning line beam completes the scanning of the object to be tested, and encodes at least one byte of the scanning sequence number into the initial scanning control signal; within the effective acquisition time of all sub-scanning control signals, all bytes of the scanning sequence number are encoded into the initial scanning control signal to generate a scanning control signal encoded with the scanning sequence number.

[0099] The number of bytes of the scan sequence number is determined according to the number of sub-scan control signals, ensuring that all bytes of the scan sequence number are encoded on the initial scan control signal within the effective acquisition time of all sub-scan control signals corresponding to each scan sequence.

[0100] Figure 3 The diagram is a level diagram of a scanning control signal and a sub-scanning control signal encoded with a scanning sequence number according to an embodiment.

[0101] like Figure 3 As shown, as an example, the scan sequence number may include 16 bytes, such as bit15, bit14, bit13...bit1, bit0.

[0102] The effective acquisition time of the sub-scan control signal is expressed as the time when the sub-scan control signal displays a high level, and the high level duration of the initial scan control signal is expressed as a scan cycle, or the time interval between the high level starting moment of the scan control signal encoded with the scan sequence number and the low level starting moment of the scan control signal encoded with the scan sequence number obtained after a preset time represents a scan cycle.

[0103] In the present disclosure, the time during which the initial scanning control signal is at a high level when scanning starts is greater than the time during which a complete sub-scanning control signal is at a high level.

[0104] like Figure 3 As shown, when scanning starts, the initial scanning control signal is at a high level, the first sub-scanning control signal is at a high level, and the sub-scanning control signal corresponding to each scanning sequence begins to be sent down. The first high level of the initial scanning control signal indicates that the OCT starts scanning and the scanning galvanometer controller starts working.

[0105] In the process of sending the sub-scan control signal, starting from the second sub-scan control signal outputting a high level, the first byte bit15 of the scan sequence number is encoded into the initial scan control signal, and the above process is repeated to gradually encode the 16 bytes of the scan sequence number into the initial scan control signal. When the high level of the 17th sub-scan control signal ends, the last byte bit0 of the scan sequence number is encoded into the initial scan control signal, thereby completing the entire encoding of the scan sequence number.

[0106] During the time when each sub-scanning control signal outputs a high level, at least one byte of a scanning sequence number is encoded onto the initial scanning control signal.

[0107] There is no limit to the time from when the scanning sequence number starts to be encoded to the initial scanning control signal, and the encoding may start when the nth sub-scanning control signal outputs a high level, where n is an integer of 2, 3, 4, etc.

[0108] After the scanning of 17 sub-scanning control signals is completed, a scanning cycle ends when the scanning control signal encoded with the scanning sequence number displays a low level for the first time. Therefore, in this embodiment, a scanning cycle starts when the initial scanning control signal displays a high level for the first time, and ends when the scanning control signal encoded with the scanning sequence number outputs a low level after the scanning sequence number encoding is completed.

[0109] like Figure 3 As shown, the scanning control signal encoded with the scanning sequence number carries the level information of 0001001110000000, where 0 represents a low level and 1 represents a high level, and 0001001110000000 is the encoding result corresponding to the scanning sequence number.

[0110] In the scanning process of the optical coherence tomography (OTC) device, the number of sub-scanning control signals is relatively large, and it is possible to ensure that all bytes of the scanning sequence number can be encoded into the scanning control signal.

[0111] The object to be measured is scanned according to the scanning control signal encoded with the scanning sequence number to determine the scanning data.

[0112] The scanning data acquired by the OCT according to the scanning control signal encoded with the scanning sequence number is line scanning data, which can be used to reconstruct a B-scan image, that is, a tomographic image.

[0113] Through the above technical solution, the scanning sequence number is encoded into the scanning control signal, so that the scanning data obtained by the scanning galvanometer through the scanning operation corresponds to the scanning sequence number one by one, thereby improving the reliability and stability of the control process.

[0114] In a possible embodiment, S13, obtaining a scan data packet corresponding to each scan sequence in the target scan sequence set, includes S41 to S42.

[0115] S41, decoding the scanning control signal encoded with the scanning sequence number to determine the scanning sequence number.

[0116] like Figure 2 As shown, specifically, the data acquisition card acquires scan data within the effective acquisition time corresponding to each scan sequence, and decodes the scan control signal encoded with the scan sequence number to decode the scan sequence number.

[0117] S42, generating a scan data packet according to the scan sequence number and the scan data.

[0118] Continuing with the above example, the data acquisition card packages the decoded scanning sequence number and the corresponding scanning data to generate a scanning data packet, so that each scanning data has a corresponding scanning sequence number.

[0119] In a possible embodiment, a data acquisition method may further include S14 to S15.

[0120] S14, determining a target scanning data packet according to a scanning sequence number corresponding to the scanning data packet.

[0121] S15, performing image reconstruction or data analysis according to the scan data corresponding to the target scan data packet.

[0122] Specifically, the PC reads the scanning data packet from the data acquisition card, and filters the scanning data according to the scanning sequence number to obtain a valid scanning data packet, i.e., a target scanning data packet, and performs data analysis or image reconstruction based on the scanning data in the valid scanning data packet, thereby improving the screening efficiency of valid data, being able to obtain valid data during one OCT scanning process, and improving the operating efficiency of the equipment.

[0123] Through the above technical solution, by setting the scanning sequence number in the scanning sequence, each scanning data and each scanning sequence have a one-to-one correspondence with the scanning sequence number, thereby improving the stability and reliability of the control process. In addition, during the control process, there is no need to reset the scanning galvanometer and the data acquisition card, and there is no need to interrupt the data acquisition work, thereby improving the operating efficiency of the scanning equipment and the data processing efficiency.

[0125] Based on the same concept, the present disclosure also provides a data acquisition system 100, such as Figure 4 As shown, it includes: a first acquisition module 110, a scanning module 120, and a second acquisition module 130.

In the process of the scanning galvanometer controller performing scanning according to the scanning sequence, since the scanning sequence has a corresponding scanning sequence number, the scanning data packets sampled and packaged by the data acquisition card have a one-to-one correspondence with the scanning sequence and the scanning sequence number, thereby improving the stability and reliability of the control process.
