Uses For Scientific Digital Imaging
Science and medicine are changing our understanding of the world around us with Scientific Digital Imaging. At the smallest and the largest setting, we can view the world through much more precise lenses and capture pictures we have never seen before. Insolvable puzzles, in fields as diverse as philosophy and astrophysics, are succumbing to analysis. With digital imaging and sophisticated computer programs, the sciences, including medicine, are changing our view of the world in which we live.
Micro imagining has allowed the smallest things to leap into focus. Cellular studies in biology and medicine can now be captured digitally and recorded for analysis. The ability to peer into the underlying structure of cells has opened the door to scientific discovery of how cells split, grow and die.
Underwater cameras can probe the depths in ways never dreamed of before. Scientists recently discovered a submerged mountain range under an arctic glacier than was previously unknown and unsuspected. Using motion detectors in the wild, scientists have been able to record highly endangered species without disturbing their natural habitats. This might one day contribute to efforts for conservation of these disappearing species.
Scientists who look at the stars, astrophysicists, use digital imaging to capture light that is outside the visual spectrum for humans. They can capture this data, and with the help of advanced computer applications, analyze light as old as thirteen billion years, possibly leftover from the Big Bang itself. Microwave radiation and the detection of gamma waves are now possible via digital imaging, though they have remained invisible to detection for all the generations that humans have looked to the night sky.
Our universe is expanding, not static, as was believed as recently as a hundred years ago. We know this now because the light from far away galaxies is red shifted. This means the galaxy is moving away from us in space. If the light from a galaxy is blue shifted, it means it is moving towards us in space.
Even philosophy has bee impacted by advances in digital imaging. Rene Descartes in his book titled Meditations in the year 1641 proposed that consciousness existed separately from the human brain and interacted with it via the pineal gland. Digital images of the brain in action have cast doubts that this is the true origin of consciousness.
Doctors now use digital imagining to examine their patients. This is used by surgeons to determine when to operate. Neonatal imagining can help doctors diagnose medical conditions while a child is still in the uterus. Dentists also use sophisticated images to evaluate the health of the bones for the jaw.
So, from outer galaxies to the chair in the dentist office, Scientific Digital Imaging is changing the way science understands the universe around us. Life can now be examined at a cellular level, contributing to our understanding of medicine and genetics. The inaccessible place on the planet have come into view. With advances continuing, this may be just the tip of the iceberg of discovery.
