Title
Unsupervised lesion detection on lung CTs with deep learning

Summary
The aim of this project is to detect unhealthy lesions of any size at their locations. It shall help the physicians to recognize locations where tumour lesions could be.

The architecture of the project is an adversarial autoencoder which is trained on healthy subjects. The autoencoder will then reconstruct the input at the output. Healthy images are correct reconstructed, unhealthy images have differences at the locations of the lesions. To recognized a tumour lesion the output is subtracted from the input.

Aims

- detect tumour lesions of any kind and size
- show the locations of the tumour lesions
- reach a sensitivity rate of 95%
