[0033] Figure 1 This is an application scenario diagram of the cell smear scanning method provided by one embodiment of the present application. Figure 1 As shown, data can be transmitted between the scanning device 101 and the processing device 102 through the network, and the processing device 102 controls the scanning device 101 to use a ×1 lens to shoot the cell smear to obtain a global cell image of the cell smear; the processing device 102 displays the global cell image in full and provides a selection interface for the scanning mode of the global cell image; the scanning mode includes a dilution scanning mode and a normal scanning mode, and the scanning accuracy of the dilution scanning mode is lower than that of the normal scanning mode; the processing device 102 controls the scanning device 101 to use a high-magnification magnification lens and use a preset scanning method corresponding to the dilution scanning mode to scan the cell smear in response to the selection operation of the dilution scanning mode; the magnification of the high-magnification lens exceeds 40 times; the processing device 102 also controls the scanning device 101 to use a high-magnification magnification lens and use a preset scanning method corresponding to the normal scanning mode to scan the cell smear in response to the selection operation of the normal scanning mode.

[0034] The present application embodiment provides a cell smear scanning method, such as Figure 2 As shown, the method comprises the following steps:

[0035] Step S201, controlling the ×1 lens to photograph the cell smear to obtain a global cell image of the cell smear.

[0036] It is understandable that the global cell image obtained by photographing the cell smear based on the ×1 lens has a fast shooting speed. Although the accuracy is not enough, it is sufficient for the user to see the cell distribution of the cell smear.

[0037] Step S202, the global cell image is fully displayed, and a selection interface for a scanning mode of the global cell image is provided; the scanning mode includes a dilution scanning mode and a normal scanning mode, and the scanning accuracy of the dilution scanning mode is lower than that of the normal scanning mode.

[0038] By displaying the global cell image in full, the user can observe the cell distribution of the cell smear, and then the user can select which scanning mode to use to scan the cell smear in the scanning mode selection interface according to the cell distribution of the cell smear. If the number of cells in the cell smear is small based on the global cell image, the user can select the dilution scanning mode to scan and detect the cell smear, avoiding the use of high-precision scanning methods when the number of cells in the cell smear is small, effectively improving the scanning speed; if the number of cells in the cell smear is large based on the global cell image, the normal scanning mode is selected to scan and detect the cell smear, avoiding the use of high-precision scanning methods when the number of cells in the cell smear is large, effectively ensuring the scanning accuracy. Through this setting, the scanning speed and scanning accuracy of the cell smear are effectively taken into account.

[0039] In actual use, since the nucleated cells in the bone marrow tissue are densely distributed, a high-precision scanning method is usually required for the bone marrow cell smear, so the normal scanning mode can be selected to scan the bone marrow cell smear. In addition, the nucleated cells in the peripheral blood are sparsely distributed, so a high-precision scanning method is usually not required for the peripheral blood smear, so the dilution scanning mode can be selected to scan the peripheral blood smear.

[0040] Step S203, in response to the selection operation of the dilution scanning mode, controlling the high-magnification magnification lens to scan the cell smear using a preset scanning method corresponding to the dilution scanning mode; the magnification of the high-magnification magnification lens exceeds 40 times;

[0041] Step S204, in response to the selection operation of the normal scanning mode, the high-magnification magnification lens is controlled to scan the cell smear using a preset scanning method corresponding to the normal scanning mode.

[0042] Specifically, the scanning accuracy can be controlled by controlling the number of scanning fields of the same area by the high-magnification magnification lens. For example, if the dilution scanning mode is selected, the high-magnification magnification lens is controlled to scan the cell smear in a manner of scanning fields of 1 in the same area; if the normal scanning mode is selected, the high-magnification magnification lens is controlled to scan the cell smear in a manner of scanning fields of 4 in the same area. Of course, the purpose of controlling the scanning accuracy of the dilution scanning mode and the scanning accuracy of the normal scanning mode can also be achieved by controlling other scanning parameters, which are all within the protection scope of this patent.

[0043] In the prior art, most of the cell morphology tests on cell smears are performed by automated scanning. However, in the automated scanning process, a unified scanning method is used for all cell smears, which cannot take into account both the scanning speed and the scanning accuracy of the cell smears.

[0044] In order to solve the above problems, the present application provides a cell smear scanning method, which controls a ×1 lens to shoot a cell smear to obtain a global cell image of the cell smear; displays the global cell image in its entirety, and provides a selection interface for the scanning mode of the global cell image; the scanning mode includes a dilution scanning mode and a normal scanning mode, and the scanning accuracy of the dilution scanning mode is lower than that of the normal scanning mode; in response to the selection operation of the dilution scanning mode, controls the high-magnification magnification lens to scan the cell smear using a preset scanning method corresponding to the dilution scanning mode; the magnification of the high-magnification magnification lens exceeds 40 times; in response to the selection operation of the normal scanning mode, controls the high-magnification magnification lens to scan the cell smear using a preset scanning method corresponding to the normal scanning mode. The present application provides a scanning mode selection interface for users to select a corresponding scanning mode based on a global cell image obtained by roughly photographing a cell smear. If the number of cells in the cell smear shown based on the global cell image is small, the high-magnification magnification lens is controlled to use a dilution scanning mode to scan and detect the cell smear, thereby effectively improving the scanning speed; if the number of cells in the cell smear shown based on the global cell image is large, the high-magnification magnification lens is controlled to use a normal scanning mode to scan and detect the cell smear, thereby effectively ensuring the scanning accuracy. Through this setting, the scanning speed and scanning accuracy of the cell smear are effectively taken into account.

[0053] The second scanning module 34 is used for controlling the high-magnification magnification lens to scan the cell smear using a preset scanning mode relative to the normal scanning mode in response to the selection operation of the normal scanning mode.

[0054] The above-mentioned cell smear scanning device 30 controls the ×1 lens to shoot the cell smear to obtain the global cell image of the cell smear; displays the global cell image in full and provides a selection interface for the scanning mode of the global cell image; the scanning mode includes a dilution scanning mode and a normal scanning mode, and the scanning accuracy of the dilution scanning mode is lower than that of the normal scanning mode; in response to the selection operation of the dilution scanning mode, the high-magnification magnification lens is controlled to scan the cell smear using a preset scanning method corresponding to the dilution scanning mode; the magnification of the high-magnification magnification lens exceeds 40 times; in response to the selection operation of the normal scanning mode, the high-magnification magnification lens is controlled to scan the cell smear using a preset scanning method corresponding to the normal scanning mode.
