Why We Really Have Digital Imaging

By Adriana Noton

In the 1960's and 1970's, the scientific community and the military, needed to develop a way to capture images in a way that was far less fragile than using ordinary film. Ordinary film is susceptible to extreme heat and cold, and other things of that nature. Hence, a new imaging technique was born. In time, it became far less expensive and was more affordable to the public. More people seem to now prefer digital to classic film. Read on and find out why we really have digital imaging.

Digital image acquisition actually means to create an image from a physical view. The term either relates to or includes all or one of the following, processing, compression, storage, printing, and the actual display of the image. This creation is done by a camera or another that acquires images like a camera.

When you obtain one image from another, it is called digitizing. Digitizing involves sampling and the quality of sound in order to process the image. Scanners and sonar are two examples of this type of imaging. Creating an image from a mathematical formula or a geometric model in known as rendering.

Forensic science has come a long way in the past several years in being able to prove the accuracy of digital images. This is extremely important to law enforcement and the health care industry who required a greater deal of accuracy.

Molecular imaging was first used in radio pharmacology so that the molecular pathway structures inside organisms could be studied, without them knowing we were studying them, and disturbing their patterns. This was a major breakthrough in being able to diagnose diseases like cancer, neurological and heart problems.

Medical imaging biomarkers allow this type of molecular study to go even farther. Biomarkers are made to interact with whatever goes on around them, and so whenever there is a noticeable change in the molecules, the biomarkers change. This allows researchers to identify if new medications are working, and it also can help detect diseases early.

There are different image resolutions for digital images and they can be expressed in a lot of different ways. One of which is pixel, which is basically like a count of width by height. Spatial refers to how closely lines can be resolved. Spectral distinguishes color images. Temporal resolves points in time like a movie camera, and radiometric distinguishes intensity.

When referring to all types of images, both digital and film, high resolution is the detail that the image holds. The more detail that you see in the image, then you know that the resolution is higher. The resolution can also be affiliated with size like, line per mm, or lines per in. With relation to the entire image.

Well, now that you know a little more about the history of a digital imaging system, does it make you want to get out there, buy a new camera and start making your own images? Think of what you can create. One of the great benefits of digital, is that you can enhance and edit your photos, you do not have the opportunity to do that with regular film. Look at the advantages that digital has brought to our lives. Happy snapping, now that you know the inside story of imaging station.
