[0003] ECT imaging systems use a wide variety of radionuclides, but the built-in radionuclide library of these systems is limited. For radionuclides not included in the factory specifications, medical personnel need to add new radionuclides to the ECT imaging system to meet different diagnostic needs.

However, medical staff often need to spend a lot of time consulting literature to determine the key parameters for configuration. This configuration method is inefficient, error-prone, and may lead to decreased image quality and reduced diagnostic accuracy. Summary of the Invention

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0055] The nuclide information configuration method for an ECT imaging system provided in this application can automatically configure new nuclides in the ECT imaging system, improving configuration efficiency and accuracy. ECT imaging systems include, but are not limited to, SPECT imaging systems and PET imaging systems. The method includes, as follows: Figure 1 The steps shown are as follows:

[0056] Step S101: Obtain basic information about the target nuclide.

[0057] The new nuclide that the user wishes to configure in the ECT imaging system can be called the target nuclide. It can be displayed on the screen as follows: Figure 2 The interface for creating a new nuclide is shown. Users can enter basic information about the target nuclide on this interface, including its name and half-life. Figure 2 In the example shown, the target nuclide is named In-111 and has a half-life of 2419200 s.

[0058] Step S102: Based on the nuclide name and half-life, control the detector in the ECT imaging system to collect data for a set acquisition time to obtain the energy spectrum distribution data of the target nuclide at the set acquisition time.

[0059] After obtaining the nuclide name and half-life of the target nuclide, it can be determined whether the user has issued an automatic detection command. Specifically, refer to... Figure 2 Automatic detection controls (such as...) can be provided in the new nuclide interface. Figure 2 As shown in 201), if the user does not click the auto-detection control, it is determined that the user has not issued an auto-detection command; if the user clicks the auto-detection control, it is determined that the user has issued an auto-detection command.

[0060] Once the user issues an automatic detection command, the detector in the ECT imaging system can be controlled to collect data for the set acquisition time, thereby obtaining the energy spectrum distribution data of the target nuclide at the set acquisition time.

[0061] For example, if the acquisition time is set to 10 minutes, the detector can be controlled to continuously acquire data for 10 minutes to obtain the energy spectrum distribution data of the target nuclide corresponding to 10 minutes. As another example, if the acquisition time is set to 15 minutes, the detector can be controlled to continuously acquire data for 15 minutes to obtain the energy spectrum distribution data of the target nuclide corresponding to 15 minutes.

[0062] Step S103: Based on the energy spectrum distribution data, obtain the parameter configuration information of the target nuclide.

[0063] After obtaining the energy spectrum distribution data, the data can be analyzed to obtain the parameter configuration information of the target nuclide. This parameter configuration information may include at least one of the following: energy peak, energy window, scattering window, and branching ratio. The scattering window may include a left scattering window and a right scattering window.

[0064] Step S104: Configure the target nuclide in the ECT imaging system according to the parameter configuration information.

[0065] After obtaining the parameter configuration information of the target nuclide, the target nuclide can be configured in the ECT imaging system according to the parameter configuration information.

[0066] In the aforementioned method for configuring nuclide information in an ECT imaging system, basic information about the target nuclide is obtained, including its name and half-life. Based on the nuclide name and half-life, the detector in the ECT imaging system is controlled to acquire data for a set acquisition duration, obtaining energy spectrum distribution data of the target nuclide at the set acquisition duration. Based on the energy spectrum distribution data, parameter configuration information for the target nuclide is obtained. The target nuclide is then configured in the ECT imaging system according to the parameter configuration information. The solution provided in this application can automatically configure the parameters of a new nuclide in the ECT imaging system without requiring medical personnel to consult reference materials or perform manual configuration, thus improving the configuration efficiency of new nuclides and avoiding image quality degradation and reduced diagnostic accuracy due to configuration errors. Furthermore, based on the real-time acquired energy spectrum distribution data, this application can obtain more objective and accurate parameter configuration information, reducing interference from subjective human factors.

[0067] In one embodiment, based on energy spectrum distribution data, parameter configuration information of the target nuclide is obtained, including:

[0068] Analyze the energy spectrum distribution data to obtain at least one of the following information: energy peak, energy window, scattering window, and branching ratio; based on at least one of the following information, obtain the parameter configuration information of the target nuclide.

[0069] A preset algorithm can be invoked to analyze the energy spectrum distribution data and obtain at least one of the following information: energy peak, energy window, scattering window, and branching ratio; at least one of the following information can be used as the parameter configuration information of the target nuclide.

[0070] Taking parameter configuration information including: energy peak, branching ratio, energy window, left scattering window, and right scattering window as an example:

[0071] Reference Figure 2 The newly created nuclide interface includes a parameter configuration information display area. After obtaining the target nuclide's energy peak, branching ratio, energy window, left scattering window, and right scattering window, the specific values ​​of the energy peak, branching ratio, energy window, left scattering window, and right scattering window can be displayed in the parameter configuration information display area.

[0072] Some target nuclides include multiple energy peaks, multiple branching ratios, multiple energy windows, multiple left scattering windows, and multiple right scattering windows. Therefore, the parameter configuration information display area can include multiple sub-display areas, which can be in the form of rows. Figure 2 In the example shown, the parameter configuration information display area displays three sub-display areas, referred to as the first sub-display area, the second sub-display area, and the third sub-display area, with each sub-display area displayed on a single line.

[0073] Refer again Figure 2 Furthermore, new controls for sub-display areas can be added to the new nuclide interface (such as...). Figure 2 The 202 shown) and delete control (such as Figure 2 (See 203). If the user clicks "Add Control", a sub-display area can be added to the parameter configuration information display area; if the user clicks "Delete Control", a sub-display area can be deleted from the parameter configuration information display area.

[0074] Help controls can be set in the new nuclide interface (such as...) Figure 2 (As shown in 204); if the user clicks the help control, relevant instructions for creating a new nuclide can be displayed to help the user understand how to automatically create a new nuclide.

[0075] You can set a sliding control (such as...) in the new nuclide interface. Figure 2 As shown in 205), if the user triggers the sliding control, the displayed sub-display area can be scrolled.

[0076] In one embodiment, after configuring the target nuclide in the ECT imaging system according to the parameter configuration information, the method provided in this application further includes:

[0077] Display a list of drugs; respond to the user's drug selection action in the drug list, determine the selected drug; associate the selected drug with the target nuclide.

[0078] It is possible Figure 2 The newly created radionuclide interface shown displays a list of drugs. Figure 2 In the example shown, the drug list includes drug a, drug b, drug c, drug d, drug e, drug f, and drug g. A user can select at least one drug from the drug list; the selected drug is referred to as the user-selected drug. If the user selects both drug a and drug c, drug a can be associated with the target nuclide, and drug c can be associated with the target nuclide; correspondingly, drug a and drug c are displayed in the associated drug table.

[0079] If the user confirms that the drug associated with the target nuclide is correct, they can click the "Confirm" control on the "Create Nuclide" interface (e.g., ...). Figure 2 (As shown in 206); In response to the user's confirmation operation, it can be determined that the target nuclide has been successfully configured in the ECT imaging system, and the target nuclide configuration process can be exited. If the user does not want to continue configuring the target nuclide, they can click the cancel control on the new nuclide interface (e.g., Figure 2 As shown in 207), at this point, the target nuclide will not be configured in the ECT imaging system, and the target nuclide configuration process can be exited.

[0080] In one embodiment, the method provided in this application further includes:

[0081] In a coordinate system showing the change of count rate with energy, the energy spectrum distribution curve corresponding to the energy spectrum distribution data is displayed, and at least one of the energy peak, energy window and scattering window is shown.

[0082] After obtaining the energy spectrum distribution data, an energy spectrum distribution curve can be generated; additionally, a coordinate system showing the count rate as a function of energy can be generated, with energy on the horizontal axis and the count rate on the vertical axis; the energy spectrum distribution curve can be displayed in this coordinate system, such as... Figure 3 As shown.

[0083] Furthermore, after obtaining the energy peak, energy window, left scattering window, and right scattering window from the energy spectrum distribution data, these can also be displayed in the aforementioned coordinate system, such as... Figure 3 As shown.

[0084] Users can click on the automatic analysis control (such as...) Figure 3 As shown in 301), in response to this operation, specific values ​​for the energy peak, energy window, branching ratio, left scattering window, and right scattering window can be displayed. Figure 4 In the example shown, with the acquisition time set to 10 minutes and 5 seconds, the specific values ​​of the energy peak are 88 keV, the specific values ​​of the branching ratio are 95%, the specific values ​​of the energy window are 80 keV to 98 keV, the specific values ​​of the left scattering window are 70 keV to 90 keV, and the specific values ​​of the right scattering window are 95 keV to 105 keV.

[0085] After viewing the specific values ​​of the energy peak, energy window, branching ratio, left scattering window, and right scattering window, if the user is concerned about the accuracy of the results and needs to continue data acquisition, they can click the "Continue Data Acquisition" control (e.g., ...). Figure 4 As shown in 302), at this point, the detector can be controlled to collect data for the originally set collection duration or another set collection duration; if the user confirms that the results are correct and no further collection is needed, the user can click the application control (such as...). Figure 4 As shown in 303), the results of this acquisition are used as the parameter configuration information for the target nuclide, and the results are displayed in the sub-display area of ​​the new nuclide interface. If the user clicks the "Confirm" control on the new nuclide interface (such as...), Figure 2 As shown in 206), it can be determined that the target nuclide has been successfully configured in the ECT imaging system, the target nuclide is saved in the nuclide library of the ECT imaging system, and the configuration process of the target nuclide is exited.

[0086] In one embodiment, the detector in the ECT imaging system is controlled to acquire data for a set acquisition duration to obtain energy spectrum distribution data of the target nuclide at the set acquisition duration, including:

[0087] Multiple preset acquisition durations are sorted in ascending order to obtain a sequence of preset acquisition durations. Preset acquisition durations are then selected sequentially from this sequence. For each preset acquisition duration, the detector in the ECT imaging system is controlled to acquire data according to that duration, obtaining the initial energy spectrum distribution data of the target nuclide at that specified acquisition duration. Based on the changes in the initial energy spectrum distribution data of the target nuclide from at least the previous preset acquisition duration to the current preset acquisition duration, it is determined whether the initial energy spectrum distribution data has stabilized. If the initial energy spectrum distribution data has not stabilized, the next preset acquisition duration is acquired sequentially. If the initial energy spectrum distribution data has stabilized, the acquisition of the next preset acquisition duration is stopped, and the energy spectrum distribution data is obtained based on the initial energy spectrum distribution data of the target nuclide at the selected preset acquisition durations.

[0088] For example, multiple set collection durations are 10 minutes, 11 minutes, 12 minutes, 13 minutes, 14 minutes, and 15 minutes. The multiple set collection durations are sorted in ascending order, resulting in a set collection duration sequence of {10 minutes, 11 minutes, 12 minutes, 13 minutes, 14 minutes, 15 minutes}.

[0089] In ascending order, the first set acquisition duration selected from the set acquisition duration sequence is 10 minutes; the detector can be controlled to continuously acquire data for 10 minutes to obtain the energy spectrum distribution data of the target nuclide at 10 minutes. This energy spectrum distribution data is called the initial energy spectrum distribution data. The second set acquisition duration selected from the set acquisition duration sequence is 11 minutes; the detector can be controlled to continuously acquire data for 11 minutes to obtain the initial energy spectrum distribution data of the target nuclide at 11 minutes.

[0090] It allows for comparison of the changes in the initial energy spectrum distribution data of the target nuclide from 10 minutes to 11 minutes.

[0091] If the change in the initial energy spectrum distribution data of the target nuclide from 10 minutes to 11 minutes is not significant, it indicates that the initial energy spectrum distribution data is stabilizing, and the acquisition of the next set acquisition time can be stopped in the set acquisition time sequence. The energy spectrum distribution data is determined from the initial energy spectrum distribution data of the target nuclide at 10 minutes and the initial energy spectrum distribution data of the target nuclide at 11 minutes.

[0092] If the change indicates a significant change in the initial energy spectrum distribution data of the target nuclide from 10 minutes to 11 minutes, it means that the initial energy spectrum distribution data has not stabilized. In this case, a third set acquisition time, i.e. 12 minutes, can be obtained in the set acquisition time sequence. The detector can be controlled to continuously acquire data for 12 minutes to obtain the initial energy spectrum distribution data of the target nuclide at 12 minutes.

[0093] Based on the initial energy spectrum distribution data of the target nuclide at 10 minutes, 11 minutes, and 12 minutes, the changes in the initial energy spectrum distribution data of the target nuclide from 10 minutes to 12 minutes can be obtained.

[0094] If the changes in the initial energy spectrum distribution data of the target nuclide from 10 minutes to 12 minutes are not significant, it indicates that the initial energy spectrum distribution data is stabilizing, and the acquisition of the next set acquisition time can be stopped in the set acquisition time sequence. The energy spectrum distribution data is determined from the initial energy spectrum distribution data of the target nuclide at 10 minutes, 11 minutes, and 12 minutes.

[0095] If the change indicates a significant change in the initial energy spectrum distribution data of the target nuclide from 10 minutes to 12 minutes, it means that the initial energy spectrum distribution data has not stabilized. In this case, the fourth set acquisition time, i.e. 13 minutes, can be obtained in the set acquisition time sequence. The detector can be controlled to continuously acquire data for 13 minutes to obtain the initial energy spectrum distribution data of the target nuclide at 13 minutes.

[0096] Based on the initial energy spectrum distribution data of the target nuclide at 11 minutes, 12 minutes, and 13 minutes, the changes in the initial energy spectrum distribution data of the target nuclide from 10 minutes to 13 minutes can be obtained.

[0097] If the changes in the initial energy spectrum distribution data of the target nuclide from 11 minutes to 13 minutes are not significant, it indicates that the initial energy spectrum distribution data is stabilizing, and the acquisition of the next set acquisition duration can be stopped in the set acquisition duration sequence. The energy spectrum distribution data is determined from the initial energy spectrum distribution data of the target nuclide at 11 minutes, 12 minutes, and 13 minutes.

[0098] If the change indicates a significant variation in the initial energy spectrum distribution data of the target nuclide from 11 minutes to 13 minutes, it means that the initial energy spectrum distribution data has not stabilized. In this case, the fourth set acquisition time, i.e. 14 minutes, can be obtained in the set acquisition time sequence. The detector can be controlled to continuously acquire data for 14 minutes to obtain the initial energy spectrum distribution data of the target nuclide at 14 minutes.

[0099] Based on the initial energy spectrum distribution data of the target nuclide at 12 minutes, 13 minutes, and 14 minutes, the changes in the initial energy spectrum distribution data of the target nuclide from 12 minutes to 14 minutes can be obtained.

[0100] If the changes in the initial energy spectrum distribution data of the target nuclide from 12 minutes to 14 minutes are not significant, it indicates that the initial energy spectrum distribution data is stabilizing, and the acquisition of the next set acquisition duration can be stopped in the set acquisition duration sequence. The energy spectrum distribution data is determined from the initial energy spectrum distribution data of the target nuclide at 12 minutes, 13 minutes, and 14 minutes.

[0101] If the change indicates a significant change in the initial energy spectrum distribution data of the target nuclide from 12 minutes to 14 minutes, it means that the initial energy spectrum distribution data has not stabilized. In this case, the fifth set acquisition time, i.e. 15 minutes, can be obtained in the set acquisition time sequence. The detector can be controlled to continuously acquire data for 15 minutes to obtain the initial energy spectrum distribution data of the target nuclide at 15 minutes.

[0102] Based on the initial energy spectrum distribution data of the target nuclide at 13 minutes, 14 minutes, and 15 minutes, the changes in the initial energy spectrum distribution data of the target nuclide from 13 minutes to 15 minutes can be obtained.

[0103] If the changes in the initial energy spectrum distribution data of the target nuclide from 13 minutes to 15 minutes are not significant, it indicates that the initial energy spectrum distribution data is stabilizing, and the acquisition of the next set acquisition duration can be stopped in the set acquisition duration sequence. The energy spectrum distribution data is determined from the initial energy spectrum distribution data of the target nuclide at 13 minutes, 14 minutes, and 15 minutes.

[0104] If the changes in the initial energy spectrum distribution data of the target nuclide from 13 minutes to 15 minutes indicate significant variations, it suggests that the initial energy spectrum distribution data has not stabilized. In this case, a longer set acquisition duration, such as 16 minutes, can be added to the set acquisition duration sequence. The detector can be controlled to continuously acquire data for 16 minutes to obtain the initial energy spectrum distribution data of the target nuclide at 16 minutes. This process is repeated until the initial energy spectrum distribution data of the target nuclide from the previous two set acquisition durations to the currently selected set acquisition duration shows minimal variation. Finally, the energy spectrum distribution data can be determined from the initial energy spectrum distribution data of the previous two set acquisition durations and the currently selected set acquisition duration.

[0105] In one embodiment, energy spectrum distribution data is obtained based on the initial energy spectrum distribution data of the target nuclide at a selected set acquisition time, including:

[0106] From the initial energy spectrum distribution data of the target nuclide at the selected set acquisition time, determine the initial energy spectrum distribution data of the target nuclide at the last selected set acquisition time; use the initial energy spectrum distribution data of the target nuclide at the last selected set acquisition time as the energy spectrum distribution data.

[0107] For example, based on the initial energy spectrum distribution data of the target nuclide at 12 minutes, the initial energy spectrum distribution data of the target nuclide at 13 minutes, and the initial energy spectrum distribution data of the target nuclide at 14 minutes, the change of the initial energy spectrum distribution data of the target nuclide from 12 minutes to 14 minutes is obtained.

[0108] If the change in the initial energy spectrum distribution data of the target nuclide from 12 minutes to 14 minutes is not significant, it indicates that the initial energy spectrum distribution data is stabilizing, and the acquisition of the next set acquisition duration can be stopped in the set acquisition duration sequence. Since 14 minutes is the last selected set acquisition duration, the initial energy spectrum distribution data of the target nuclide at 14 minutes can be determined as the energy spectrum distribution data.

[0109] Another example is that, based on the initial energy spectrum distribution data of the target nuclide at 13 minutes, 14 minutes, and 15 minutes, the change in the initial energy spectrum distribution data of the target nuclide from 13 minutes to 15 minutes is obtained.

[0110] If the change in the initial energy spectrum distribution data of the target nuclide from 13 minutes to 15 minutes is not significant, it indicates that the initial energy spectrum distribution data is stabilizing, and the acquisition of the next set acquisition duration can be stopped in the set acquisition duration sequence. Since 15 minutes is the last selected set acquisition duration, the initial energy spectrum distribution data of the target nuclide at 15 minutes can be determined as the energy spectrum distribution data.

[0111] The solution provided in this application achieves a high degree of standardization and normalization in its operational procedures; it offers an intuitive and user-friendly interface; and it employs a visualization approach to data presentation, significantly reducing the technical barrier to configuring new nuclides in ECT imaging systems. This not only improves the efficiency of nuclide creation but also ensures operational consistency and accuracy. With the solution provided in this application, even operators lacking extensive experience can quickly and accurately create new nuclides by following standard procedures. The solution provided in this application automatically analyzes energy spectrum distribution data, reducing manual operation and improving efficiency. Furthermore, it enhances parameter accuracy by analyzing energy spectrum distribution data acquired in real-time by the detector.

[0112] This application provides a method for configuring radionuclide information in an ECT imaging system, the method comprising the following steps:

[0113] Step S110: In response to the user's command to create a new nuclide, obtain the basic information of the target nuclide.

[0114] The new nuclide that the user wishes to configure in the ECT imaging system can be called the target nuclide. The user can trigger a new nuclide command on the screen; in response to the user's new nuclide command, the screen can display something like... Figure 2 The interface for creating a new nuclide is shown. Users can enter basic information about the target nuclide on this interface, including its name and half-life. Figure 2 In the example shown, the target nuclide is named In-111 and has a half-life of 2419200 s.

[0115] Step S111: Based on the nuclide name and half-life, control the detector in the ECT imaging system to acquire data and display the acquired energy spectrum distribution curve on the screen.

[0116] After obtaining the nuclide name and half-life of the target nuclide, it can be determined whether the user has issued an automatic detection command. Specifically, refer to... Figure 2 Automatic detection controls (such as...) can be provided in the new nuclide interface. Figure 2 As shown in 201), if the user does not click the auto-detection control, it is determined that the user has not issued an auto-detection command; if the user clicks the auto-detection control, it is determined that the user has issued an auto-detection command.

[0117] After confirming that the user has issued an automatic detection command, the detector in the ECT imaging system can be controlled to collect data for a set acquisition duration, obtaining the energy spectrum distribution data of the target nuclide at that set acquisition duration. Based on the energy spectrum distribution data of the target nuclide at the set acquisition duration, an energy spectrum distribution curve corresponding to that set acquisition duration is formed. In the coordinate system containing this energy spectrum distribution curve, the horizontal axis represents energy, and the vertical axis represents the count rate. The energy spectrum distribution curve and its coordinate system are displayed together on the screen, such as... Figure 3 As shown.

[0118] Step S112: In response to the user's automatic analysis command, the energy spectrum distribution curve is analyzed to obtain the recommended parameter configuration information of the target nuclide.

[0119] Users can click on the automatic analysis control (such as...) Figure 3 (As shown in 301); if the user clicks the automatic analysis control, it is confirmed that the user has issued an automatic analysis command. In response to the user's automatic analysis command, the energy spectrum distribution curve can be analyzed to obtain the recommended parameter configuration information of the target nuclide; the recommended parameter configuration information may include the specific values ​​of energy peak, energy window, branching ratio, left scattering window and right scattering window.

[0120] Recommended parameter configuration information can be displayed on the screen, specifically showing the values ​​for the energy peak, energy window, branching ratio, left scattering window, and right scattering window. For example... Figure 4 In the example shown, with the acquisition time set to 10 minutes and 5 seconds, the specific values ​​of the energy peak are 88 keV, the specific values ​​of the branching ratio are 95%, the specific values ​​of the energy window are 80 keV to 98 keV, the specific values ​​of the left scattering window are 70 keV to 90 keV, and the specific values ​​of the right scattering window are 95 keV to 105 keV.

[0121] Step S113: Based on the user's input of the recommended parameter configuration information, determine the parameter configuration information of the target nuclide.

[0122] Users can view the recommended parameter configuration information displayed on the screen to determine if the recommended parameter configuration information is correct; if it is correct, the recommended parameter configuration information can be used as the parameter configuration information for the target nuclide.

[0123] like Figure 4 The example shown is for users to view. Figure 4 After displaying the specific values ​​for the energy peak, energy window, branching ratio, left scattering window, and right scattering window, if you confirm that these values ​​are correct, you can click the application control (such as...). Figure 4 (As shown in 303); at this time, the recommended parameter configuration information is used as the parameter configuration information of the target nuclide, and the parameter configuration information of the target nuclide is displayed in the sub-display area of ​​the newly created nuclide interface.

[0124] Step S114: Configure the drug information related to the target nuclide based on the parameter configuration information and basic information.

[0125] It is possible Figure 2 The newly created radionuclide interface shown displays a list of drugs. Figure 2 In the example shown, the drug list includes drug a, drug b, drug c, drug d, drug e, drug f, and drug g. A user can select at least one drug from the drug list; the selected drug is referred to as the user-selected drug. If the user selects both drug a and drug c, drug a can be associated with the target nuclide, and drug c can be associated with the target nuclide; correspondingly, drug a and drug c are displayed in the associated drug table.

[0126] If the user confirms that the drug associated with the target nuclide, the parameter configuration information of the target nuclide, and the basic information of the target nuclide are correct, then the user can click the "Confirm" control on the "Create Nuclide" interface (e.g., ...). Figure 2 (As shown in 206); in response to the user's confirmation operation, it can be determined that the target nuclide has been successfully configured in the ECT imaging system and associated with the corresponding drug; at this point, the target nuclide configuration process can be exited.

[0127] The solution provided in this application can automatically configure the parameters of new nuclides in the ECT imaging system without requiring medical staff to consult materials or perform manual configuration, thereby improving the configuration efficiency of new nuclides and avoiding the decline in imaging quality and diagnostic accuracy due to configuration errors. Furthermore, based on the real-time acquired energy spectrum distribution data, this application can obtain more objective and accurate parameter configuration information, reducing the interference of human subjective factors.

[0128] In one embodiment, determining the parameter configuration information of the target nuclide based on user input regarding recommended parameter configuration information includes:

[0129] In response to the user's command to continue acquisition, the detector is controlled to continue acquisition, and the energy spectrum distribution curve obtained from the continued acquisition is displayed on the interface; in response to the user's command to automatically analyze, the energy spectrum distribution curve obtained from the continued acquisition is analyzed, and the parameter configuration information of the target nuclide is obtained based on the analysis results and the user's adjustment results.

[0130] Users can click on the automatic analysis control (such as...) Figure 3 (As shown in 301); if the user clicks the automatic analysis control, it is confirmed that the user has issued an automatic analysis command. In response to the user's automatic analysis command, the energy spectrum distribution curve can be analyzed to obtain the recommended parameter configuration information of the target nuclide; the recommended parameter configuration information may include the specific values ​​of energy peak, energy window, branching ratio, left scattering window and right scattering window.

[0131] Recommended parameter configuration information can be displayed on the screen, specifically showing the values ​​for the energy peak, energy window, branching ratio, left scattering window, and right scattering window. For example... Figure 4 In the example shown, with the acquisition time set to 10 minutes and 5 seconds, the specific values ​​of the energy peak are 88 keV, the specific values ​​of the branching ratio are 95%, the specific values ​​of the energy window are 80 keV to 98 keV, the specific values ​​of the left scattering window are 70 keV to 90 keV, and the specific values ​​of the right scattering window are 95 keV to 105 keV.

[0132] Users can view the recommended parameter configuration information displayed on the screen to determine if the information is correct; if it is incorrect and data collection needs to continue, they can click the "Continue Data Collection" control (e.g., ...). Figure 4 As shown in 302), at this time, the detector can be controlled to continue collecting data according to the original set collection time or another set collection time, so as to obtain the energy spectrum distribution curve obtained by the continued collection, and the energy spectrum distribution curve obtained by the continued collection will be displayed on the screen.

[0133] Users can click the automatic analysis control again (such as...) Figure 3(As shown in 301); if the user clicks the automatic analysis control, it is confirmed that the user has issued an automatic analysis command. In response to the user's automatic analysis command, the energy spectrum distribution curves obtained from the continued acquisition can be analyzed to obtain analysis results; these analysis results include another recommended parameter configuration information for the target nuclide.

[0134] If the user confirms that another recommended parameter configuration information included in the analysis results is incorrect, they can adjust that other recommended parameter configuration information to obtain the parameter configuration information for the target nuclide. If the user confirms that the other recommended parameter configuration information included in the analysis results is correct, they can use that other recommended parameter configuration information as the parameter configuration information for the target nuclide.

Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.
