It should be apparent that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and it should be understood that the present application is not limited by the example embodiments described herein.
Lymphedema is a chronic disease that is difficult to cure and its treatment requires long-term and complex assessment. The existing evaluation methods such as a water replacement method have the disadvantages of resource waste, complex operation, low precision and infection risk; lymphoscintigraphy is costly and may cause allergies due to the use of contrast agents. MRI and CT, while imaging clearly, are expensive and unsuitable for patients with metallic implants. Moreover, treatment effect evaluation often depends on subjective judgment of doctors, which may generate deviation due to personal differences of doctors, and lack of quantification tools may cause misjudgment on disease changes.
Therefore, in view of the above problems, the technical idea of the present application is to automatically determine whether there is an abnormality in the volume of the lymphedema limb of the monitored lymphedema limb patient according to the semantic interactive fusion characteristics between the limb volume data and the treatment data by acquiring the time series of the lymphedema limb volume data of the monitored lymphedema limb patient and the treatment data (physical treatment and medication treatment) of the monitored lymphedema limb patient and performing local time sequence feature extraction, semantic reasoning and semantic fusion on the lymphedema limb volume data and the treatment data respectively by adopting the AI-based data analysis and processing technology, and generate corresponding early warning. Therefore, the automatic limb volume abnormality detection and early warning function can be realized, misjudgment caused by subjective experience of doctors is reduced, time sequence information and semantic association in volume data and treatment data are effectively captured, medical staff is helped to comprehensively understand the condition of patients, and more intelligent lymphedema limb volume measurement data management is realized.

It will be appreciated that the time series of lymphedema limb volume data can reflect changes in limb volume over time, and that by analysing trends in limb volume, potential abnormal conditions of limb volume can be identified. While patient physical therapy data and medication data may help to understand the specifics of physical therapy and medication that the patient receives, and thus analyze the effects of these treatments on changes in limb volume. By combining and analyzing the lymphedema limb volume data and the treatment data, a more perfect limb volume abnormality identification model can be constructed, so that the accuracy of limb volume abnormality detection is improved. In particular, in one embodiment of the present application, the acquisition of lymphedema limb volume data and treatment data may be performed by clinical treatment recordings of the patient.
