Emerging Trends in Transmission Electron Microscopy for Medical Applications
This paper is an overview of imaging methods used for research and diagnosis that appear in the literature. There are several types of scientific research and imaging modalities, including photography, microscopy, ultrasound, Xray, computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). The type of images used will depend on the part of the body the researcher wants to see in the image and the types of images readily available to the patient. For many years, medical imaging has played an important role in the early detection, diagnosis, and treatment of cancer and other diseases. In some cases, medical imaging tests are the first step in preventing the spread of cancer by detecting it early, and in many cases the cancer can be cured or eliminated. CT scans, MRIs, ultrasounds and X-ray imaging are very important tools in fighting various diseases. Medical imaging is also used to create accurate computer models of body systems, organs, tissues, and cells used in anatomy and physiology classes in medical school.
Advances in Medical Physics for Regenerative Medicine
Globally, the cost of hard tissue repair and regeneration is in the hundreds of billions of dollars every year, and as the population ages, this demand has grown significantly. Structures made of calcium phosphate minerals, such as bone and teeth, are considered to be hard tissues. Techniques for regenerative medicine and smart biomaterialbased tissue engineering have the exciting potential to fill this critical need. By engineering the material's responsiveness to internal or external stimuli, smart biomaterials and constructs can have instructive/inductive, triggering/stimulating, or stimulating effects on cells and tissues. They can also have intelligently tailored properties and functions that can encourage tissue repair and regeneration. Smart scaffolds and stem cell constructs for bone tissue engineering, intelligent medication delivery systems to improve bone regeneration and intelligent dental resins.
SEM Imaging for Advanced Bio Materials
Scanning electron microscopy (SEM) is one of the popular methods for imaging the microstructure and morphology of materials. In an SEM, a low-energy electron beam hits the material and scans the surface of the sample. As the beam reaches and enters the material, various interactions occur that result in the emission of photons and electrons from or near the sample surface. To produce an image, the received signal produced by the electron-sample interaction is detected with different types of detectors, depending on the her SEM mode used. There are various his SEM modes for characterization of materials including biomaterials. B.
