42 AI Research Medical images are used for medical diagnosis and treatment. Medical images can be acquired by various modalities, such as computed tomography (CT), ultrasound, X-ray radiography, MR imaging (MRI), Positron emission tomography-computed tomography (PET-CT), pathology fundus images and Optical coherence tomography (OCT). The images acquired from these modalities are shown in the figure below with more details about these image modalities in the following section. In the previous figure clockwise: chest X-Rays, brain MRIs, fundus image on the rear eye for detection and grading of hypertensive retinopathy and liver ultrasound imaging techniques are shown. In the next figure brain CTs, such as those used to detect lesions tumors or clots, OCT images to diagnose retinal disease , whole slide images (WSI) used in computational pathology and PET-CT scans which are mainly used for cancer patients. I will follow with a short description of each of those imaging modalities. X-rays are non-invasive imaging techniques. X-rays are mostly used for diagnosing bone fracture. X-rays are also used by mammograms for breast cancer detection. Other most
