Classification of Illness

Classification of Illness

The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

To leverage comparative learning for improved distinction between benign and malignant nodules.

Main Methods:

3D lung nodule segmentation using U-Net to isolate nodules.
Contrastive learning within Nodule-CLIP to align image, class, and attribute features.
Optimization of image feature extraction networks using feature similarities and differences.

Main Results:

Achieved a 90.6% benign and malignant classification rate on the LIDC-IDRI dataset.
Obtained a 92.81% recall rate for pulmonary nodule classification.
Demonstrated improved ability to distinguish similar lung nodules.

Conclusions:

The Nodule-CLIP model offers significant advantages in lung nodule classification accuracy.
