In Ian Pearson's book, he points out the possibility of being able to create a digital self in the future that based on neurological information. It means we can upload ourselves onto a computer and live in a digital form. As Google hired Ray Kurzweil to create the ultimate artificial intelligence controlled brain, the time of using this technology wont take too long. But, we might have been looking for the secret of immortality in the wrong places. In addition, a game called "SOMA" is the game that describe a future that everybody lives as a digital form, and character we controlled is the only human remains, this is kinda creepy, but deserves us to think carefully, do we really want to live like that?

It is a non-invasive diagnostic procedure which helps to diagnose the disease and confirm the pregnancy. It also helps to detect the any abnormalities before giving delivery to baby. There are different types of ultrasound. They are Abdominal ultrasounds, Pelvic ultrasound Imaging, Transabdominal, Transvaginal, Transrectal, Obstetric Ultrasound Imaging and Carotid and Abdominal Aorta Ultrasound Imaging. There are some advantages and disadvantages of ultrasound. It helps to detect blood flow through vessels, it is quick and painless procedure, it is allowed to use to pregnant women and it is widely available and less expensive also. However, many cancers can not be detected by ultrasound, to do this procedure stomach need to be empty and it is hard to stay without food for a long hours and sometimes it is unable to determine whether or not a mass is malignant, and a biopsy will be recommended. Hence , ultrasound is  one of the important medical technology.

With HD imaging and Df² technology, this small VeinViewer model is the brightest and only handheld vein illuminator that provides benefits for all patients during the entire Pre-, During- and Post- vascular access procedure. It is ideal for alternate care facilities, such as surgery and blood/plasma centers, as well as home healthcare and Emergency Medical Services (EMS), VeinViewer Flex is designed for durability and maximum portability. Flex is also suited for hospital departments such as the Emergency Department and NICU where space requirements and speed of assessment demand an ultra-portable and reliable vein finder.
FUNCTIONS:
With HD imaging and exclusive Df2 (digital full field) technology, VeinViewer is the only vein illuminator that provides benefits for all patients during the entire Pre, During and Post vascular access procedure.

Projected near-infrared light is absorbed by blood and reflected by surrounding tissue. The information is captured, processed and projected digitally in real time directly onto the surface of the skin. It provides a real time accurate image of the patient’s blood pattern.

VeinViewer patented technology, using AVIN™ (Active Vascular Imaging Navigation), allows you to see blood patterns up to 15mm deep and clinically relevant veins up to 10mm. With VeinViewer clinicians can see peripheral veins, bifurcations and valves and assess in real time the refill/flushing of veins. With visualization Pre-, During- and Post-procedure, clinicians can potentially avoid complications from accidental puncture. Improving the total vascular access procedure, not just the stick.

There are many different techniques or types of MRI scans that can be carried out. Each one offers the radiologist (specialist doctor) specific information, to best show what the problem might be. The information gained using MRI should help to diagnose the medical condition you might have.

Microscope is an optical instrument having a magnifying lens or a combination of lenses for inspecting objects too small to be seen or too small to be seen distinctly and in detail by the unaided eye. 

·Microscopes help the scientists to study the microorganisms, the cells, the crystalline structures and the molecular structures; they are one of the most important diagnostic tools when the doctors examine the tissue samples.

· Microscopes has opened up a whole new dimension in science ,  By using Microscopes scientists were able to discover the existence of the microorganisms , study the structure of cells , and see the smallest parts of plants , animals , and fungi.

·  Electron microscopes help create the very tiny electrical circuits found on Silicon microchips ,  Scanning microscopes are much more sophisticated , and they have higher magnifications than light-refracting microscopes .

·Microscopes are used to diagnosis the illness in the hospitals and the clinics all over the world, Microscopes magnify the blood samples, and so, the doctors can see the malaria parasites attacking the red blood cells.

· Helps you to see things that you can't with just your naked eyes. 

· Helps microbiologists with their work. 

· Compared to other scientific means of viewing minute organisms or things, it's less expensive and readily available. 

·Compared to magnifying glasses, it can have higher magnification.
