Medical physics in 2020: will we ... [Australas Phys Eng Sci Med. 2008] - PubMed - NCBI - 1 views

  • From the time when Roentgen and other physicists made the discoveries which led to the development of radiology, radiotherapy and nuclear medicine, medical physicists have played a pivotal role in the development of new technologies that have revolutionized the way medicine is practiced today. Medical physicists have been transforming scientific advances in the research laboratories to improving the quality of life for patients; indeed innovations such as computed tomography, positron emission tomography and linear accelerators which collectively have improved the medical outcomes for millions of people. In order for radiation-delivery techniques to improve in targeting accuracy, optimal dose distribution and clinical outcome, convergence of imaging and therapy is the key. It is timely for these two specialties to work closer again. This can be achieved by means of cross-disciplinary research, common conferences and workshops, and collaboration in education and training for all. The current emphasis is on enhancing the specific skill development and competency of a medical physicist at the expense of their future roles and opportunities. This emphasis is largely driven by financial and political pressures for optimizing limited resources in health care.

ASIMO - Wikipedia, the free encyclopedia - 0 views

    ASIMO The robot "Honda began developing humanoid robots in the 1980s, including several prototypes that preceded ASIMO. It was the company's goal to create a walking robot which could not only adapt and interact in human situations, but also improve the quality of life. The E0 was the first bipedal (two-legged) model produced as part of the Honda E series, which was an early experimental line of humanoid robots created between 1986 and 1993. This was followed by the Honda P series of robots produced from 1993 through 1997, which included the first self-regulating, humanoid walking robot with wireless movements.[6][7]"

How Technology Has Changed Our Lives in the Last Five Years - The Center of Technology - 0 views

  •  
    "Over the last five years, technology has been rapidly changing and expanding in every field imaginable. Smart phones are now capable of acting as standalone computer devices that can take pictures, search the Internet, send emails and text messages and yes, they even make phone calls. While it might seem that the technology of today has reached its limits, it is still actually spreading its proverbial wings. Only twenty or so years ago, personal computers were becoming small enough and affordable enough for families to buy them for home use. Since then, the world of technology has shown no signs of slowing down and practically every device available today is somehow tied to computer technology. It seems hard these days to fathom the original size of computers and how small they have become in the last ten years, but within the last five years they have become even smaller and somehow more powerful and faster than ever before! The Internet allows people to connect with family, friends, and work colleagues from across the globe in the push of a button. Communication options have literally exploded in the instant avenues of text and video based chat as well as the near instantaneous method of email. Gone are the days where one had to post a letter and wait a week or more for a response and long distance phone calls are unnecessary for anyone with a computer, a webcam, and a speedy Internet connection. Automobiles are now being manufactured with standard GPS and emergency call features for the convenience and safety of drivers and their passengers, making the days of carrying a map completely unnecessary and improving the peace of mind of anyone who must travel the roads alone or at night. Computerized cars are now potentially at risk in much the same fashion as a personal computer as a moderately skilled hacker can theoretically take over basic functions of a vehicle - including its engine. Yes, technological advancement has changed our lives completely, and not al

    "However, it is fast becoming time to reckon with what the future holds for our computers - and technology in general." This site is useful to me because it leaves open any possibility about computers of the future. It talks about how computer technology can only improve. I will use this website to help improve my predictions. This website is reliable because it goes along with a lot of predictions about future computing devices.

Medical uses expand for human tissue from 3-D printers | The Portland Press Herald / Ma... - 0 views

    "SAN FRANCISCO - 3-D printing, used to construct everything from art to toys to spare parts for the space station, may one day produce human organs at a hospital near you. click image to enlarge A 3-D printed prosthetic nose and ear are displayed at an industry show in London in November. The technology may eventually help reduce organ shortages. Bloomberg News photo by Chris Ratcliffe Select images available for purchase in the Maine Today Photo Store The 20-year-old technology uses liquid materials that become hard as they print out three-dimensional objects in layers, based on a digital model. Current medical uses are in dentistry, for hard-material crowns, caps and bridges, as well as prosthetics. Last year, a 3-D printer was used to create a structure from moldable polymer that replaced more than 75 percent of a patient's skull. Now, Organovo Holdings Inc. is using 3-D printers to create living tissue that may one day look and act like a human liver, able to cleanse the body of toxins. Drugmakers and cosmetic companies already plan to use 3-D printed human tissue to test new products. Eventually, the technology may help reduce organ shortages and cut transplant rejections as patients receive new organs constructed from their own cells. "3-D printing is like a new tool set," said Organovo Chief Executive Officer Keith Murphy. "You can make a living tissue you can grow outside the body. That's the core of our technology. How can you be smart about doing that?" Organovo already is preparing to sell strips of liver tissue to drugmakers this year to be used to test toxicity of potential treatments, Murphy said in a telephone interview. The San Diego-based company's five- and 10-year goals are first to use a patient's own cells to print tissue strips that can be used to patch failing organs, and finally to be able to create entire new organs. The first 3-D printer was produced in 1992. Since then, a variety of materials have been used as the t

What could be the Post Silicon Era? | Technologically Insane - 0 views

  •  
    "The "nanowires" is another alternative of the post silicon era, but there are many issues such as connecting them to the rest of the transistor, improving the semiconductor property, and ensuring the nanotubes are sized and positioned correctly. " Nanowires might be one of the alternatives of replacing silicon.

The Dawn of the Age of Artificial Intelligence - Erik Brynjolfsson and Andrew McAfee - ... - 0 views

  •  
    "We're going to see artificial intelligence do more and more, and as this happens costs will go down, outcomes will improve, and our lives will get better. Soon countless pieces of AI will be working on our behalf, often in the background. They'll help us in areas ranging from trivial to substantive to life changing. Trivial uses of AI include recognizing our friends' faces in photos and recommending products. More substantive ones include automatically driving cars on the road, guiding robots in warehouses, and better matching jobs and job seekers. But these remarkable advances pale against the life-changing potential of artificial intelligence."

The Deep-Space Suit - 0 views

  •  
    This article is useful because it explores the profound advantages of modern space technology. Several factors limit the depth of space exploration for humans. Astronauts would be able to travel further if they had better space suits. A single fault in any type of space suit is fatal, as the vast climate of space is so much different from the atmosphere of Earth and therefore completely nonsupporting of a human without full insulation and protection. High-tech space suits could not only provide better comfort to astronauts, but they could also provide more convenience and productivity, resulting in higher overall performance. Not only could improved, futuristic spacesuits enable astronauts to support themselves for an extended period of time, enabling them to travel further distances, newer technology might even be able to bring humans to places that have been far too hostile to travel before-- like Mars.
