—One pill, a glass of water, and about 8 hours is all it takes to
produce nearly 60,000 high-resolution digital photos. And patients are finding that
the latest in high-tech, digital photography is very easy to swallow. Using this new
non-invasive technology, known as a capsule endoscopy system, physicians at the
UMHS now have the ability to explore uncharted, and often unseen, territory
within a patient’s small intestines.
Capsule endoscopy is providing physicians with a clear view of obscure
gastrointestinal disorders such as bleeding or Crohn’s disease, which were
previously difficult to visually detect.
The tiny capsule records its entire journey through the digestive tract while
closely examining the 15–18 feet of the small bowel. The capsule sends two images
per second to sensors attached to a Walkman-sized digital recording device
strapped to the patient’s waist. The stored images are transformed into a digital
movie. It takes gastroenterologists about 45 minutes to review the series of images .
2.1.4 Disruptive Technologies—Will the World be Changed?
Disruptive technologies—a phrase coined by C.M. Christensen

—refer to any new
emerging technology that gradually replaces an established, matured technology in
the same basic application. Examples include the transistor that replaced the vacuum
tube, the digital camera that replaced the conventional film camera, cell phones that
are replacing the wired phone, as well as capsule and virtual colonoscopy, which may
eventually replace the real colonoscopy. Fuel cells in the automotive industry, which
may 1 day replace the internal combustion engi ne, the personal digital assistant (PDA)
or i-Phone that may take a significant market share from laptops and cell phones, may
also be defined as disruptive technologies.
In many cases, an innovative replacement technolog y may emerge at a time when
an established company struggles to improve the performance of their current
product. If the company ignores the new technology, it may eventually lose its entire
share of the market. The transistor came into use in the late 1950s, but its early
performance was poorer than that of vacuum tubes that had equivalent functions (e.g.,
in radios). RCA, Philips, and General Electric controlled the vacuum tube market in
the 1960s. RCA does not exist today, and GE is not making microprocessors, the
industry that evolved from the transistor industry.
Early digital cameras suffered from poor picture quality and low resolution.
Kodak, with more than 60% of the photographic materials industry, did not believe
that digital photography performance could improve to a degree that it would replace
conventional photography. Therefore, Kodak entered the digital camera business too
late, and consequently fell from its pre-eminent position at the top of the photographic
industry in 2003.
