Thermal Cameras in Modern Medicine

Mammography vs Thermography

The Truth About Breast Thermography Breast thermography is a clinical diagnostic procedure which uses highly specialized infra red cameras to measure the heat coming from the body, in this case, the breast. Thermography has been approved for this purpose for many years by the US FDA (United States Food and Drug Administration) and in the past two years (2001-2002) many new doctors and technicians have entered the field.

Thermal Imaging Cameras in Airports After the outbreak of SARS flu outbreak a few years ago, several major airports in Asia discovered the benefits of utilizing infrared thermal imaging camera technology. The Thermal cameras are an effective way to implicate infrared surveillance and virus monitoring in order to control the spread by travelers of the new H1N1 virus- commonly known as the swine flu.

Health Care Reform? According to recent health care reform news, Congress is still miles away from agreeing on a comprehensive health care reform bill. Although Senators and members of the House of Representatives are proposing bills and debating many aspects of the final proposal, bipartisan politics and differing agendas are making agreement nearly impossible.

Thermal Cameras in Modern Medicine Cancer is said to be a dangerous disease; however it is not necessary that all cancer patients die, as with the timely detection and treatment it is possible to survive from cancer. Today medical science has turned to technology to help them detect cancer cells and prevent its spread which is made possible through infrared cameras. Read the Full Story

Mammography vs Thermography According to the CDC, breast cancer is the second most common cancer among women and is one of the top ten causes of death among women in the United States. These numbers are frightening and early and accurate detection is vital in order to catch the disease in its early stages and begin lifesaving treatment. There are different methods that are used to detect breast cancer but not all of these methods can give the early detection that is required in order to save lives. Read more.

As global fears regarding swine flu increase, world governments are seeking ways to curb the spread of this potential pandemic. In today's complex and struggling economy, recommending travel restrictions is politically difficult. Vice President Joe Biden of the United States recently backpedaled on his recommendation to avoid all unnecessary travel to Mexico.

Governments are leery of any action which could potentially bankrupt the travel industry, especially when they are struggling to stimulate their economies, not weaken them. Yet the H1N1 virus is a serious threat, and while travel restrictions might be an over-reaction, health officials and political leaders know action must be taken to slow the spread of this virus.

Many world leaders are therefore turning to technology. Thermal imaging scanners have been installed at airports around the globe in an attempt to prevent individuals who have contracted the virus from entering their home countries. These thermal scanners, when trained on incoming passengers, alert airport officials when a passenger with a high fever passes. This allows health officials to approach the patient, who is then isolated from the general population until the cause of his illness is determined.

Typical Thermal Imaging for Disease Monitoring Most of Asia already has these thermal imaging scanners in place from the 2003 SARS crisis. Other countries are moving quickly to install thermal imaging technology in their own airports. In the United States, however, most airports do not have thermal technology in place. In Houston, which receives more passengers arriving from Mexico than any other American airport, airport officials have been offered scanners from the Houston fire department but the CDC has refused them. Critics of thermal imaging argue that these scanners do not detect illness in individuals who are in the latency period of the virus, when individuals display no symptoms but are still contagious. Now, health leaders are fighting against a wildly spreading virus. If airport thermal imaging had been in place, swine flu might have been detected sooner and been better contained. If government officials are unwilling to take aggressive action against the spread of the virus by imposing economically-problematic travel bans, they must seek other solutions, including thermal imaging scanners. If an ounce of prevention is worth indeed a pound of cure, then if thermal imaging scanners had already been in place in border airports, health officials might have prevented a pandemic. Even now, if the government acts quickly and decisively, thermal scanners still might mitigate the rapid spread of the swine flu.
