    I think this website will be a great reference through out this project. It provides us with a descriptive overview of the current medical technology available to the public, as well as a glimpse of the technological possibilities that may be part of our future. This source appears to be reliable because it is a medical website. The author also includes citations throughout the article to prove the information is correct.

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

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.

CAT Scan (Computed Tomography or CT Scan): Procedure, Preparation, and Results - 0 views

  •  
    "A computed tomography (CT) scan uses X-rays to make detailed pictures of structures inside of the body. During the test, you will lie on a table that is attached to the CT scanner, which is a large doughnut-shaped machine. The CT scanner sends X-rays through the body area being studied. Each rotation of the scanner provides a picture of a thin slice of the organ or area. All of the pictures are saved as a group on a computer. They also can be printed. In some cases, a dye called contrast material may be used. It may be put in a vein (IV) in your arm, or it may be placed into other parts of your body (such as the rectum or a joint) to see those areas better. For some types of CT scans you drink the dye. The dye makes structures and organs easier to see on the CT pictures. A CT scan can be used to study all parts of your body, such as the chest, belly, pelvis, or an arm or leg. It can take pictures of body organs, such as the liver, pancreas, intestines, kidneys, bladder, adrenal glands, lungs, and heart. It also can study blood vessels, bones, and the spinal cord. Fluoroscopy CT is a special test that is not widely available. It uses a steady beam of X-rays to look at movement within the body. It allows the doctor to see your organs move or to guide a biopsy needle or other instrument into the right place inside your body." This talks about the CAT (CT) scan. It tells how it is preformed.
