Leps : Revolution in the Field of Imaging Appliances

In 1897, German physicist Carl Ferdinand Brown invented CRT. So far, it is still everywhere, but it is bulky, consumes electricity and is expensive. Researchers have come up with an alternative called a liquid crystal display (LCD). LCD is predicted to be the savior of the display industry, and has been quite successful in the computer application industry. However, even today, liquid crystal displays are far from universal ones. This is because in addition to being thinner than the CRT, it has little advantage and therefore can not meet the wide range of needs of the imaging equipment industry.

In recent years, the field of computer vision has revolutionized. The deep learning technology accompanying the increase of data and the improvement of computing capacity has made dramatic progress in tasks such as image classification (Krizhevsky et al., 2012) and face recognition (Taigman et al., 2014) We are penetrating our daily lives. These increasingly ubiquitous advances are just beginning to touch the pathologist's microscope. Histopathology is a microscopic study of diseased cells and tissues and provides unique opportunities to apply deep learning meaningfully. Every day, innumerable tissue samples should be visually inspected to diagnose and characterize various diseases, including nearly all types of cancer (Gurcan et al., 2009). In addition, the development of full-slide imaging technology has promoted the development of digital pathology in recent years.

Medical image processing has always been a revolution. Various techniques for medical imaging include radiology, nuclear medicine, optical imaging, and image-guided intervention. Talking about radiology, especially medical imaging, the method of determining diagnostic information changes. MRI plays a pivotal role in clinical diagnosis, treatment and disease monitoring. This technique helps you create and visualize body parts, tissues or organs for clinical analysis, medical intervention and visual performance. Ultrasound, computed tomography (CT), x-ray and magnetic resonance imaging (MRI) techniques make it easy to track and monitor disease. Compared with ultrasound, CT and X-ray, MRI is one step ahead of the league. The reason is that MRI creates a very detailed image that is suitable for identifying soft tissue lesions.

Magnetic Resonance Imaging (MRI) is a noninvasive diagnostic test that takes a detailed image of the soft tissue of the body. Unlike X-ray and CT, images are created using magnetic field, radio waves, computer. It just allows your doctor to see your spine and brain within the slice as if it were a layer slice and a picture of each slice. This test is useful for the diagnosis of tumors, stroke and disc herniation. MRI scans use powerful magnets, radio waves, computers to create detailed images. Your body is made up of millions of hydrogen atoms (the body is 80% of the water). And it is magnetic. When the body is placed in a magnetic field, these atoms align with the magnetic field, as the compass points to the North Pole. Radio waves "knock down" atoms and destroy those polarities. The sensor detects the time it takes for the atom to return to its original array
