    1. Computer Technology in the Medical Field Trixie Francisco

    2. PURPOSE AND USES • Diagnosis • CT scan • X-ray generator • Ultrasound • ’Telemedicine’ • Surgery http://comps.fotosearch.com/comp/BDX/BDX107/ medical-technology_~bxp25992.jpg

    3. http://www.dmg.net/image/ct-image.jpg CT Scan • Computerised (Axial) Tomography scan.  • takes a series of X-rays and uses a computer to put them together.  • takes pictures of your body from different angles and gives a series of cross sections or 'slices' through the part of the body being scanned http://www.phedhex.com/images/dcsr/cat_scan.gif

    4. CT Scans Advantages Disadvantages • Provides a very detailed picture of the inside of the body. • give a very accurate picture of where a tumor is and how big it is.  • They also show how close major body organs are to the area that needs to be treated or operated on. • radiation exposure • Possible allergic reaction to the contrast injection. • Results and reports often take a few weeks to arrive

    5. X-Ray Generators • The two main fields in which x-ray machines are used in medicine are radiography and dentistry. • Radiography is used for areas with a high bone content • Radiotherapy — the use of x-ray radiation to treat malignant cancer cells http://upload.wikimedia.org/wikipedia/commons/f/f0/Mobile_X-ray_machine.jpg

    6. X-Ray Generators Advantages Disadvantages • Produces fast images • Can be used eliminate tumors • Can treat cancer • High doses of radiation could cause health abnormalities • Hair loss • Damaged brain cells • Damaged Thyroid gland • Etc. https://vic.pvhs.org/webpix/radiology/xray300.jpg

    7. Ultrasonography (Ultrasound) • diagnostic imaging technique used to visualize subcutaneous body structures • Common tool for Obstetrics http://msnbcmedia1.msn.com/j/msnbc/Components/Photos/ 060503/060503_ultrasoundMachine_hmed_2p.hmedium.jpg

    8. Ultrasonography Advantages Disadvantages • Does not emit radiation. • Much easier and faster than X-rays or other radiographic techniques. • Produces 2D or 3D image • Inability to penetrate gas and bone • Many cancers cannot be detected http://www.eng.cam.ac.uk/admissions/images/3d_ultrasound.jpg

    9. “TELEMEDICINE” • Telecommunication between doctors and patients or other doctors. • “store and forward” • transferring digital images from one location to another • Teleradiology • Telepathology • face-to-face consultation via Interactive Television (IATV) • Two-way video conference • Internet/web diagnosis http://www.blogcdn.com/www.telemedicineinsider.com/media/2005/11/Telemedicine.jpg

    10. “TELEMEDICINE” Advantages Disadvantages • Cuts costs • Easier to find and organize patient file, unlimited access • With IATV, doctors can conduct consultations without having to be physically with patient. • Quick and easy diagnosis • lack of hands-on interaction with patients may result in wrong diagnosis • Expensive technology • Technological problems • Limited access in rural areas

    11. Computer-assisted Surgery • a surgical concept and set of methods, that use computer technology for pre-surgical planning, and for guiding or performing surgical interventions. • Robotics that help perform surgeries. http://ftp.qucis.queensu.ca/mcl/CAS.jpg

    12. Computer Assisted Surgery Advantages Disadvantages • decreases the risk of surgical errors • improves the geometrical accuracy of the surgical gestures and also reduce the redundancy of the surgeon’s acts. • reduces the operating time. • Cost: equipments can be very expensive, maintenance • Electricity disconnection • computer malfunctions

    13. Limitations within Developing Countries Limited access of technology in countries like Cambodia Lack of funding Lack of resources No 3G technology or other programs to be able to convey IATV

    14. Future Development and Uses Telesurgery Full robotics operation Rehabilitation – implants Nanotechnology http://www.sciencedaily.com/releases/2009/06/090616080133.htm
