Embodiment 1
[0031] The embodiment of the present invention provides a DICOM image classification method, such as figure 2 Shown, including:
[0032] S201. Acquire a group of DICOM image files, where each DICOM image file in the group of DICOM image files contains a patient identification, image location information, acquisition time, and serial number corresponding to the DICOM image file.
[0033] S202: Classify the group of DICOM image files according to the patient identification to obtain m first sets, where m is a positive integer.
[0034] S203. For each first set in the m first sets, classify the DICOM image files in each first set according to the serial number, and obtain l s The second set.
[0035] Where l s Represents the number of DICOM image file sets obtained after classifying the DICOM image files in the sth set in the m first sets, 1≤s≤m.
[0036] S204. For the l s For each second set in the second set, according to the image location information, determine the slice type and slic...
Embodiment 2
[0097] The embodiment of the present invention provides a DICOM image classification device 50, such as Figure 5 As shown, the classification device 50 includes: an acquisition unit 501, a classification unit 502, and a determination unit 503.
[0098] The acquiring unit 501 is configured to acquire a set of DICOM image files, wherein each DICOM image file in the set of DICOM image files contains the patient identification, image location information, acquisition time and series corresponding to the DICOM image file number.
[0099] The classification unit 502 is configured to classify the group of DICOM image files according to the patient identification to obtain m first sets, where m is a positive integer.
[0100] The classification unit 502 is further configured to classify the DICOM image files in each first set according to the serial number for each first set in the m first sets, and obtain l s Second set, l s Represents the number of DICOM image file sets obtained after cl...

Abstract
The invention provides a method for classifying DICOM images to at least solve the problem in the prior art that required image data cannot be quickly found during three-dimensional reconstruction of medical images. The method includes: acquiring a group of DICOM image files; classifying a group of DICOM image files according to the patient identification to obtain m first sets; The DICOM image files in a collection are classified to obtain ls second collections respectively; for each second collection in the ls second collections, according to the image position information, determine the section corresponding to the DICOM image files in each second collection type and slice thickness; according to the slice thickness and section type, the ls second collections are hierarchically classified to obtain f third collections; for each third collection in the f third collections, according to the collection time, determine each The installment type corresponding to each second set in the third set. The invention is applicable to the field of image three-dimensional reconstruction.
Description
Technical field [0001] The present invention relates to the field of image three-dimensional reconstruction, in particular to a method for classifying digital imaging and communications (Digital Imaging and Communications in Medicine, DICOM for short) images. Background technique [0002] Three-dimensional reconstruction of medical images is a technology that converts a set of two-dimensional DICOM image sequences into three-dimensional images. [0003] Three-dimensional reconstruction software generally requires a group of DICOM images of the same patient, the same thickness, the same slice, the same stage and arranged in axial direction. For example, such as figure 1 As shown, in the three-dimensional reconstruction of medical images, patient 1 may be required to have a slice thickness of 0.6, an axial plane, and a group of DICOM images in the arterial phase. The group of DICOM images are arranged in axial order. However, since there is no unified classification standard in the ...
