POTS to broadband ... cable modems.

There have been 3 columns talking about broadband communications and now at the very end when it's time to compare using a telco or cableco, I'm asking does it really matter? So what if I can actually get the whole 30 Mbps with a cable network when the website I'm connecting to is running on an ISDN line at 128 Kbps? Broadband offers a lot more bandwidth than the connections many Internet servers have today. Except for the biggest websites, many servers connect to the Internet with a switched 56-Kbps, ISDN, or fractional T1 line. Even with the big websites, my home network only runs a 10 Mbps Ethernet connection to my cable modem. Maybe it doesn't matter that the cable lines are shared or that I can only get 8 Mbps from an ADSL line. Maybe the ISP that I use has a T1 line connection to the Internet so my new ADSL modem has a fatter pipe than my provider! (See table 1). It all makes me wonder what's in store for us in the future. PC technology has increased exponentially in the last 10 years with super fast processor speeds, hard disks of hundreds of gigabytes, and amazing video and audio. Internet connection speeds have failed to keep the same pace. Instead of hundreds of times better or faster--modem speeds are barely 10 times faster. Broadband connections offer some additional speed but still not comparable growth as broadband connections are still in their infancy. Rather than trying to make use of existing communication paths, maybe we need a massive infrastructure makeover of something new. How about national wireless access points so we can connect anywhere, anytime? To use the latest and fastest wireless technology you will simply need to buy another $9.95 WLAN card or download the latest super slick WLAN compression/encryption software. Perhaps it is time for a massive infra-restructuring. Consider the past massive infrastructure efforts. The telcos needed to put in their wiring infrastructure starting in the 1870s before telephones were useful to the masses. CATV was a minor player in the TV broadcast business before they installed their cabling infrastructure and went national. Even automobiles were fairly useless until roads were paved and the highway infrastructure was built!

DICOM: key concepts--part I.

In this issue and next, we're investigating different sections of the DICOM Standard to get a grip on what it's all about. The bottom line is to facilitate communication and DICOM addresses all the technical aspects to allow complying OEMs to talk to one another. In part 2, IT World completes its overview on DICOM by exploring UID, networking with DICOM, conformance, and conformance statements.

DICOM: key concepts--part II.

The objective of these two installments of IT World was to give a general overview of DICOM and to take a look at different parts of the standard to get a sense of its main themes. We found that the standard provides a common reference for all developers but does not impose a single type of implementation. This allows for innovation. The standard is also built for flexibility, able to adapt to new modalities that have a need to communicate. The speedy acceptance of DICOM by the medical imaging industry is opening new possibilities for healthcare organizations to increase the quality while decreasing the cost of patient care. All of the DICOM networked supporting medical equipment as well as the organization's computer systems made by multiple original equipment manufacturers and located at one site or many sites can communicate by means of DICOM. This gives us the opportunity for medical images to be captured and communicated quicker. The result enables physicians to make diagnoses and treatment decisions sooner. It's all good stuff and even more reason why we should endeavor to understand the basics of DICOM. DICOM is here to stay!
