GAN‐LSTM‐3D: An efficient method for lung tumour 3D reconstruction enhanced by attention‐based LSTM

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Three‐dimensional (3D) image reconstruction of tumours can visualise their structures with precision and high resolution. In this article, GAN‐LSTM‐3D method is proposed for 3D reconstruction of lung cancer tumours from 2D CT images. Our method consists of three phases: lung segmentation, tumour segmentation, and tumour 3D reconstruction. Lung

CBCT in orthodontics

International journal of health sciences, 2022
Most orthodontic patients, unlike those having implants or endodontic treatment, are children who are particularly vulnerable to ionising radiation. In orthodontics, cone-beam computed tomography (CBCT) has both hazards and benefits. Ionizing radiation, the existence of artefacts, higher costs, limited accessibility, and the need for additional ...
