Summary of Física Médica, Aplicaciones de la Física en la Medicina

00:00:00 - 00:35:00

This video discusses the use of medical physics in medicine, with applications including segmentation and visualization of three-dimensional body structures, co-registration of images, and determination of special transformation requirements for Correspondence Imaging between images of the same or different modality, or between images and the real world.

• 00:00:00 This video explains how medical physics works, and how it is used in medicine. By the end of the presentation, the presenter will discuss some of the applications of medical physics in the past, and what is happening currently. Medical physics is a field of medical research that deals with the physics of medical imaging and diagnosis. There are very few medical physics programs in the world, and those that do exist usually have a master's or doctorate degree in the field. A medical physicist is typically responsible for overseeing the use of medical imaging equipment in a hospital.
• 00:05:00 The video explains the use of radiation therapy in medical imaging, and reviews the history of radiation therapy. It also covers the use of computed tomography (CT) and magnetic resonance imaging (MRI). The video explains the advantages and disadvantages of each method, and reviews the uses of each in various medical situations.
• 00:10:00 This video explains the use of tomography (a type of imaging that uses a beams of x-rays) to see inside the body. It covers how to perform a standard tomography, how to perform a PET (positron emission tomography) tomography, and how to use a magnetic resonance imaging (MRI) scan. The video also discusses how tomography can be used to diagnose cancer, and how it can be used to measure levels of oxygen in the blood.
• 00:15:00 This video discusses the use of physics in medicine, with applications such as ultrasound and MRI. It covers the basic principles of each technology, and discusses how they can be used to diagnose and treat medical conditions.
• 00:20:00 The video discusses the use of medical physics in medicine, with applications including segmentation and visualization of three-dimensional body structures, co-registration of images, and determination of special transformation requirements for Correspondence Imaging between images of the same or different modality, or between images and the real world. This means that instead of seeing images, a registered image provides point-to-point correspondence between structures represented in the image, which is what co-registration means. There are two techniques that can be used at the same time, but cannot be observed together; one uses an intermodal registration in which a magnetic resonance image has been registered, while the other uses an atlas to visualize radiographic image quality. In addition, computer-assisted surgery using images from medical scans is discussed. The segmentation technique is explained, and then an interactive atlas is shown that allows for precise reconstruction of three-dimensional body structures. Finally, injury is discussed, and the use of segmentation and atlas technology in reconstructing injuries is highlighted. It is noted that, with the development of powerful tools, most of this information is now automated, and much is included in common medical image software.
• 00:25:00 The video discusses the advantages of an automatic medical procedure, which is independent of the operator and allows quantitative temporal tracking. It is very important in cases of cerebral atrophy, as the brain is just one part of the human body. This segmentation is done with a machine and is automated. There are also filters to produce static images, which are used to show the different areas of the body. This is done with the help of resonance. One example is the visualization of a three-dimensional skeleton. This is a multidisciplinary field which is constantly gaining knowledge. There are still many things that we do not know about medicine, and physics is one of the fields that help us to understand it.
• 00:30:00 The video discusses the dangers of magnetic resonance imaging (MRI), which is a medical procedure that uses strong magnetic fields to produce images of the body. Some people may experience negative side effects from MRI, such as nausea or headaches. However, there are also no known negative side effects from using MRI in the presence of a magnetic field, which is different from x-rays. Some people have experienced temporary muscle spasms after being exposed to MRI.
• 00:35:00 This video discusses the medical applications of physics in medicine. Francisco participates and provides a brief summary of what they discuss.
