  • Los avances tecnológicos acercan la Anatomía Patológica a la US y a la Telemedicina.
    España debe estar presentes en esta innovación.
  • http://www.nanotech-now.com/utility-fog.htm
    Nanotechnology is based on the concept of tiny, self-replicating robots.
    The Utility Fog is a very simple extension of the idea: Suppose, instead of building the object you want atom by atom , the tiny robots linked their arms together to form a solid mass in the shape of the object you wanted? Then, when you got tired of that avant-garde coffeetable, the robots could simply shift around a little and you'd have an elegant Queen Anne piece instead.
    Here's a short list of the powers you'd have or appear to have if embedded in fog:
    Creation--causing objects to appear and disappear on command.
    Levitation--causing objects to hover and fly around.
    Manipulation--causing forces (squeezing, hitting, pulling) on objects (real ones) at a distance.
    Teleportation--nearly any combination of telepresence and virtual reality between fog-filled locations
    Utility Fog: The Stuff that Dreams Are Made Of By J. Storrs Hall. He discusses the technical details and feasibility of how a swarm of nanobots ("Foglets") that can take the shape of virtually anything. Also covered are some of the possibilities. "Imagine a microscopic robot. It has a body about the size of a human cell and 12 arms sticking out in all directions. A bucketfull of such robots might form a 'robot crystal' by linking their arms up into a lattice structure. Now take a room, with people, furniture, and other objects in it -- it's still mostly empty air. Fill the air completely full of robots. The robots are called Foglets and the substance they form is Utility Fog, which may have many useful medical applications. And when a number of utility foglets hold hands with their neighbors, they form a reconfigurable array of 'smart matter.'" Dr. J. Storrs Hall Research Fellow of the Institute for Molecular Manufacturing.

    Royal Philips Electronics is not only providing time-lapsed images of the baby in the mother's womb, but is developing an environment in which you can enjoy this experience. The space is intended to emulate that of a spa and will allow you to view images of your baby on a bubble-like screen.
    A 4-D time-lapse ultrasound image like this may elicit warm emotions as parents distinguish their unborn baby's facial features and fingers for the first time, but the same cannot usually be said about the clinical environment in which such images are created.
  • The LUMA™ Cervical Imaging System shines a light on the cervix and analyzes how different areas of the cervix respond to this light. The LUMA System assigns a score to tiny areas of the cervix and produces a color map that helps the doctor decide where to biopsy. The colors and patterns on the map help the doctor distinguish between healthy tissue, potentially diseased tissue, and areas that cannot be interpreted (e.g. tissue at the edge of the screen).

    We have demonstrated the multiscale imaging capability of PAM in vivo with optical absorption contrast (see Figure 1). Our initial 50MHz photoacoustic microscope probes to a depth of 3mm—filling the penetration void of ballistic imaging—at 15μm in axial resolution and 45μm in lateral resolution: see Figure 1(b).
    We have also been able to scale the spatial resolution down to 5μm by focusing a light beam to less than the depth of one optical transport mean free path. This resolution allows in vivo imaging of capillaries, which are the smallest blood vessels: see Figure 1(a).2 The ultimate lateral resolution is optically diffraction limited, potentially yielding submicron resolution.
    We have also scaled the penetration limit up to centimeters, extending photoacoustic microscopy to macroscopy. For example, by employing a 5MHz ultrasonic transducer and an 804nm light source, we were able to increase the penetration to 3cm: see Figure 1(c).4

  • OCT delivers high resolution because it is based on light, rather than sound or radio frequency
    OCT, an interferometric technique, is able to penetrate significantly deeper into the scattering medium, for example ~3× deeper than its nearest competitor, Confocal microscopy.
    OCT is based on low-coherence interferometry.[8][9][10] In conventional interferometry with long coherence length (laser interferometry), interference of light occurs over a distance of meters. In OCT, this interference is shortened to a distance of micrometres, thanks to the use of broadband light sources (sources that can emit light over a broad range of frequencies). Light with broad bandwidths can be generated by using superluminescent diodes (superbright LEDs) or lasers with extremely short pulses (femtosecond lasers). White light is also a broadband source with lower powers.
    Depending on the use of high-brightness and wide-spectrum light sources such as superluminescent diodes or ultrashort pulse lasers, OCT has achieved sub-micrometre resolution (with very wide-spectrum sources emitting over a ~100 nm wavelength range).
    OCT delivers high resolution because it is based on light, rather than sound or radio frequency. An optical beam is directed at the tissue, and a small portion of this light that reflects from sub-surface features is collected. Note that most light is not reflected but, rather, scatters. The scattered light has lost its original direction and does not contribute to forming an image but rather contributes to glare. The glare of scattered light causes optically scattering materials (e.g., biological tissue, candle wax, or certain plastics) to appear opaque or translucent even while they do not strongly absorb light (as can be ascertained through a simple experiment — e.g., shining a red laser pointer through one's finger). Using the OCT technique, scattered light can be filtered out, completely removing the glare. Even the very tiny proportion of reflected light that is not scattered can then be detected and used to form the image in, e.g., a scanning OCT system employing a microscope.
    The physics principle allowing the filtering of scattered light is optical coherence. Only the reflected (non-scattered) light is coherent (i.e., retains the optical phase that causes light rays to propagate in one or another direction). In the OCT instrument, an optical interferometer is used in such a manner as to detect only coherent light.

  • Gloucestershire Royal Hospital and University College London Hospital (UCLH) are to trial MDL’s Optical Coherence Tomography (OCT) scanner for research into rapid in-vivo identification of cancers affecting the cervix, oesophagus, skin, lung and other organs.
    ‘Optical Coherence Tomography’ (OCT) to detect non-scattered light from a scanned Near-IR laser, from up to 2 mm deep into translucent or semi-opaque material. Subsequent image processing of the OCT signal enables real-time display of the sub-surface image to the user.
    Images 6 mm wide x 2 mm deep are provided at an optical resolution < 10 μm.
