Lesion detection is a research area within medical imaging that focuses on developing algorithms and technologies to identify and locate abnormalities, such as tumors or other abnormalities, in medical images such as X-rays, MRIs, or CT scans. This research area aims to assist healthcare professionals in early and accurate diagnosis of diseases, thus improving patient outcomes and treatment options. Various machine learning and deep learning techniques are often employed in lesion detection research to automate the process and improve the detection accuracy.
