[0046] The embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0047] Firstly, fluorescence imaging equipment undergoes changes depending on the use of the fluorescence excitation device, light guide device, and camera device. These changes alter the quality of the fluorescence image, thus affecting the surgery. Therefore, it is necessary to conduct regular and irregular testing and calibration of continuously used fluorescence imaging equipment to ensure that the imaging quality of the camera device is within the specified requirements.
[0048] The existing testing method involves preparing different concentrations of developer at any time and placing them into different test fixtures for different test contents. Due to limitations in personnel and processes, this method cannot complete the test quickly and conveniently, nor can it guarantee the stability and consistency of the test results.
[0049] To address the aforementioned technical problems, this application provides a testing method for fluorescence image quality detection. In this method, a fluorescent reagent is first determined. Based on a specified model, the mixing ratio of the corresponding all-solid-state fluorescent simulation material is calculated. Based on this mixing ratio, the corresponding all-solid-state fluorescent simulation material is prepared and added to grooves of corresponding shapes in a substrate. Fluorescence testing is then performed on the substrate with the added all-solid-state fluorescent simulation material. This method utilizes an all-solid-state fluorescent simulation material, enabling long-term use of the substrate and allowing for rapid, simple, and standardized fluorescence image quality detection in all fluorescence imaging systems.
[0050] Reference Figure 1 The diagram shows a flowchart of a fluorescence image quality detection test method provided in this application, the method comprising:
[0051] S1, determine the fluorescent reagent, and calculate the mixing ratio of the all-solid-state fluorescent simulation material corresponding to the fluorescent reagent based on the specified model;
[0052] Firstly, in this embodiment of the application, for the fluorescence detection project, a set of all-solid-state fluorescent simulation materials is required. By changing the composition ratio of the all-solid-state fluorescent simulation materials, for example, an indocyanine green IGC solution of a certain concentration of an all-solid-state simulation material, the proportions of the all-solid-state fluorescent simulation materials used are shown in Table 1:
[0053] A(nM) B(ug / g) C(mg / g) D(mL) 20 20 1.33 0.6
[0054] Table 1
[0055] In Table 1, A represents the photosensitive substance, B represents heme, C represents reflective coating, and D represents the mixed gel. The approximate mixing ratios for practical use are: A: 5–200 nM, B: 10–80 ug / g, C: 0.2–10 mg / g, and D: the volume is determined by the shape, generally 0.4–4 mL.
[0056] All-solid-state fluorescent simulants exhibit stimulated fluorescence emission characteristics similar to the fluorescent reagents they simulate, meaning they exhibit the characteristic of emitting fluorescence at the same wavelength when stimulated to emit light of a specific wavelength. Furthermore, by changing the concentration of the fluorescent simulant in the mixture, a concentration-stimulated emission luminous flux curve similar to that of the simulated fluorescent reagent can be obtained.
[0057] Substances B and C are mainly used to simulate human tissue, possessing optical transmittance, absorption, and scattering rates similar to those of human tissue. Substance D is a binder and molding agent, primarily serving to bond and shape the material.
[0058] In the actual production process, various substances are mixed together in the required proportions and stirred according to certain environmental and process requirements. Under certain conditions, the mixture is poured into a molding mold of the corresponding shape and cooled to solidify, thus obtaining a fully solid fluorescent simulation material.
[0059] In the embodiments of this application, the mixing ratio of all-solid-state fluorescent simulation materials can be determined by establishing a specified model.
[0060] Specifically, the process involves obtaining the correspondence between various mixing ratios of all-solid-state fluorescent simulation materials and real-world image parameters; based on this correspondence, obtaining a first curve relating fluorescence emission flux to the molar mass of the excited light-emitting material; calculating a second curve relating heme, reflective coating concentration, and fluorescence transmittance; determining a first mapping relationship between the first curve and indocyanine green (IGC), and using the second curve to determine a second mapping relationship between IGC and heme and reflective coating concentration; and obtaining the specified model based on the first mapping relationship, the second mapping relationship, and the curves relating fluorescence flux to screen grayscale.
[0061] For example, in the embodiments of this application, the luminance of stimulated fluorescence emission of different fluorescent reagents, concentrations, and tissue depths can be simulated, and these data can be collected to establish corresponding mathematical models. Specifically, through a large number of well-designed experiments with different substance ratios, including but not limited to the ratio of different amounts of substances, changes in display image parameters (such as brightness, grayscale, etc.), the corresponding linear or nonlinear relationships between various parameters, and confidence analysis of experimental data, numerical curves 1 (molar mass of substance A - stimulated fluorescence emission luminous flux), 2 (concentration of B and C - fluorescence transmittance), and 3 (fluorescence luminous flux - screen grayscale) can be established, etc.
[0062] It's important to clarify that all numerical curves are obtained by setting different independent variables (e.g., molar mass of substance A, concentrations of substances B and C, fluorescence flux), and then experimentally measuring the corresponding strain values (e.g., fluorescence emission flux, fluorescence transmittance curve, screen grayscale). Based on these experimental data, several data points can be determined in a two-dimensional coordinate system. Then, software such as Matlab is used to fit the data to obtain a fitting formula, and the confidence level is verified. Once the data reliability is acceptable, the numerical curve can be confirmed as acceptable.
[0063] By using the numerical correspondence curves obtained from these experiments, an empirical mathematical model based on the experimental results can be established. One implementation scheme is as follows:
[0064] In this mathematical model, since ICG emits fluorescence when excited at different concentrations, curve 1 reflects the ICG concentration (hereinafter referred to as xICG) onto the molar mass (Ma) of substance A. Because substances B and C, at different concentrations, simulate the optical absorption and scattering properties of human tissue, curve 2 establishes a mapping relationship between the depth of ICG in the human body (distance h from the surface of the observed human tissue) and the concentrations of substances B and C (Cb, Cc). Combining these two mapping relationships, it can be derived that the solution of the fluorescent reagent (ICG) and its depth in the human body (distance from the surface of the observed human tissue) can be mapped to the mixing ratio of solid substances (xICG, h) → f(Ma, Cb, Cc). The volume and mass of substance D can then be determined based on the required volume.
[0065] Thus, when it is necessary to simulate the fabrication of a test phantom of a certain concentration of ICG at a specific depth in human tissue, the volume and mass of D can be calculated first, and Ma, Cb, and Cc can be obtained through the refractive relation. Then, Ma is multiplied by the molecular weight of A to obtain the mass of A; B and C are obtained by multiplying the total mass by the depth to obtain their respective required masses. A high-precision electronic scale can then be used to weigh the materials and fabricate them into the required shape according to a specific process.
[0066] Finally, after A, B, C, and D are determined and manufactured, they can be tested and verified using optical detection via curve 3.
[0067] Secondly, prepare the fluorescent reagents for testing. Select a specific fluorescent agent, such as ICG solution, according to the testing requirements, and prepare different concentrations of fluorescent agents as needed. Then, based on the previously established mathematical model, select appropriate proportions to mix and prepare the fluorescent agents corresponding to different concentrations. After preparation, calibrate each agent individually, and input the calibration data into the testing software. Finally, determine the mixing ratio of the all-solid-state fluorescent simulation material using the testing software.
[0068] S2, based on the mixing ratio, produces the corresponding all-solid-state fluorescent simulation material;
[0069] In the actual production process, based on the determined mixing ratio of the all-solid-state fluorescent simulation material, the mass of the excited light material, the mass of the heme, the mass of the reflective coating, and the mass of the mixed gel are determined.
[0070] According to the mass of each substance, the various substances are mixed together and stirred according to certain environmental and process requirements. Under certain conditions, the mixture is poured into a molding mold of the corresponding shape and cooled to solidify, thus obtaining a fully solid fluorescent simulation material.
[0071] S3, add the all-solid-state fluorescent simulation material to the corresponding shaped groove in the matrix;
[0072] After obtaining the all-solid-state fluorescent simulation material according to the mixing ratio, the all-solid-state fluorescent simulation material is added to, for example... Figure 2 The groove in the substrate shown.
[0073] It should be noted that various grooves of different shapes are set in the grooves of the substrate, such as... Figure 2 The substrate shown features circular grooves of different radii, polygonal grooves of different sizes, and rectangular grooves of different lengths. These different groove shapes can meet various testing requirements.
[0074] S4, fluorescence testing was performed on the matrix with added all-solid-state fluorescent simulation material.
[0075] Specifically, in this embodiment, the substrate is made of black opaque plastic material, and the substrate has different proportions depending on the field of view size of the lens being tested, as shown in the reference. Figure 3 The image shows a testing fixture system with an aspect ratio of 16:9. Figure 3 It includes a computer, an image acquisition card, a fluorescence camera system to be tested, an illumination source, a motion controller, and a two-dimensional translation stage.
[0076] The top of the substrate is a transparent cover plate for sealing, which mainly serves to prevent water and moisture, and to give the all-solid fluorescent simulation material in the substrate good long-term stability.
[0077] exist Figure 3 In the middle, there is a two-dimensional translation stage: it carries the fluorescent test phantom and receives instructions to move the phantom to the designated position.
[0078] Z-axis translation stage: This stage can mount and fix the lens of the fluorescence imaging system under test. The stage has a rotating mechanism to fix the lens of the system under test at different viewing angles for testing purposes. The translation stage receives commands and moves the lens of the system under test to a specified height.
[0079] Illumination source: Divided into white light source and fluorescent excitation light source, used for illuminating and exciting fluorescent reagents to produce fluorescent emission light. The brightness and intensity of the light source can be changed according to instructions. Alternatively, the illumination system of the fluorescence imaging system under test can be used for illumination and fluorescence excitation.
[0080] Image acquisition card: Used to connect to and receive images captured by the fluorescence imaging system under test, and transmit them to the monitor and computer. It also receives instructions to save the acquired images, record video, and perform other functions.
[0081] Computer: Responsible for software operation and data analysis and calculation.
[0082] Motion controller: Responsible for sending and receiving instructions for the motion and action system of the entire system.
[0083] pass Figure 3 The test system shown can place the substrate and the fluorescence imaging system under test into the corresponding positions of the test fixture. The operator only needs to follow the software steps to operate and confirm, and the performance test of the fluorescence image can be completed. The test results are calculated by the software in the computer.
[0084] The above-described testing methods can not only test the imaging quality of the current fluorescence camera system, but also show the long-term changing trend of the fluorescence camera system by plotting test curves, so as to make plans for replacing spare parts.
