LINEAR ACCELERATOR (LINAC)
2008-04-30 16:37:00 A linear particle accelerator (also called a linac) is an electrical device for the acceleration of subatomic particles. This sort of particle accelerator has many applications, from the generation of X-Rays in a hospital environment, to an injector into a higher energy synchrotron at a dedicated experimental particle physics laboratory. The design of a linac depends on the type of particle that is being accelerated: electron, proton or ion. They range in size from a cathode ray tube to the 2-mile long Stanford Linear Accelerator Center in California.CONSTRUCTION & OPERATIONA linear particle accelerator consists of the following elements:1.)The particle source. The design of the source depends on the particle that is being accelerated. Electrons are generated by a cold cathode, a hot cathode, a photocathode, or RF ion sources. Protons are generated in an ion source, which can have many different designs. If heavier particles are to be accelerated, (e.g. uranium ions), a specialized ...

UAE STUDENT DEVELOPED LOW-COST PROSTHETIC ARM
2008-04-26 08:33:00 An united arab emirates (UAE) engineering student has developed an artificial hand known as the Myoelectric Hand Prosthesis. The prosthetic hand costs just 500 Dirhams whereas a similar device would cost 30,000 Dirhams in Europe. Abdul Hafidh Al Zubaidi, who is in his twenties and set to complete his senior Bio-Medical Engineering project, was inspired to design a prosthetic hand after seeing some of his friends who lost their limbs in car accidents."The prosthetic hand I created is available in the UAE but it is mass produced in Europe, and commands a high price.""The good thing about my robotic hand is that it is affordable. I would love to help many poor people out there who need a myoelectric arm. If I can manage mass production of these devices it would cost me less than Dh500 and I would not charge people more than that," said Al Zubaidi.The prosthetic hand allows amputees to have independent, easy, efficient and natural-like control of the artificial fingers. The myoelectric ... More About: Student , Cost , Low cost
WORKING PRINCIPLE OF FIRST BIONIC ARTIFICIAL ARM
2008-04-26 08:31:00 (CLICK PICTURE TO ENLARGE)A woman fitted with the world's first "bionic arm" controlled by thought alone has been given back a sense of feeling. Claudia Mitchell, 26, a former US marine, regained the ability to carry out simple tasks such as cutting up food when she was fitted with the prosthetic arm last year.Now doctors have re-routed the ends of arm nerves to a patch of skin on her chest — allowing her to regain the sensation of having her lost hand touched.A new study of her wrist, hand and elbow function found she could use the artificial limb intuitively and could perform tasks four times quicker than with a conventional prosthesis.Ms Mitchell, who had her left arm amputated after a motorcycle accident, told doctors: "I just think about moving my hand and elbow, and they move. I think, 'I want my hand open' and it happens. My original prosthesis wasn't worth wearing — this one is."In a commentary published in The Lancet medical journal, Dr Leigh Hochberg, a neurologis...

CONNECTING BRAINS TO ARTIFICIAL BRAIN
2008-04-26 08:26:00 Northwestern University researchers of washington have pioneered a technique called targeted muscle reinnervation (TMR), which allows an artificial limb to respond directly to the brain’s signals, making it much easier to use than traditional motorized body parts.The technique, which is still under development, allows wearers to open and close their artificial hands and bend and straighten their artificial elbows nearly as naturally as their own arms.“The idea is that when you lose your arm, you lose the motors, the muscles and the structural elements of the bones. But the control information should still be there in the residual nerves,” said Dr Todd A Kuiken, a physiatrist at the Rehabilitation Institute of Chicago and professor at Northwestern University.He conceived the idea of taking the residual nerves that once carried the commands from the brain to produce arm, wrist and hand movements, and of connecting them to the chest muscles so that the signals can be used to move...

GAMMA KNIFE
2008-04-26 08:20:00 Gamma Knife is a neurosurgical device used to treat brain tumors with radiation therapy. The device was invented by Lars Leksell, a Swedish neurosurgeon, in 1967 at the Karolinska Institute in Sweden.The Leksell Gamma Knife device contains 201 cobalt-60 sources of approximately 30 curies (1.1 TBq) each, placed in a circular array in a heavily shielded assembly. The device aims gamma radiation through a target point in the patient's brain. The patient wears a specialized helmet that is surgically fixed to their skull so that the brain tumor remains stationary at target point of the gamma rays. A killing dose of radiation is thereby sent through the tumor in one treatment session, while all surrounding brain tissues receive less than a killing dose.FEATURES OF GAMMA KNIFERadiosurgery uses high doses of radiation to kill cancer cells and shrink tumors, delivered with surgical precision to avoid damaging healthy brain tissue. The key to the success of Gamma Knife surgery is its ability...
TEMPERATURE PILL
2008-04-25 15:20:00 The radio pill relies on a temperature-sensitive quartz crystal oscillator whose vibration frequencies are well known for temperatures ranging from 60 °C to 150 °C. For instance, the crystal oscillates at 262.25 kilohertz at the normal body temperature of 37 °C. The electronic components calculate the temperature and transmit the data as a digital signal. Power comes from a silver oxide hearing aid battery that holds enough energy for nine days of temperature readings. The capsule remains in the body for only 24 to 36 hours before it is eliminated.The temperature readings are transmitted wirelessly to a handheld receiverdata recorder. As the digital signal induces a voltage on the pill's communication coils, this voltage creates a quasistatic magnetic field with a radius of about a meter. When a doctor holds the receiver to the small of a patient's back, a magnetic coupling between the pill and the receiver induces a voltage in the handheld device's antenna, which is...

SCHOLARSHIP TIPS FOR PhD APPLICATION
2008-03-24 17:20:00 ScholarshipsA surprising number of students fail to see that identifying scholarships can be one of the most important parts of the successful scholarship search. There are thousands and thousands of scholarships available to students through internet searches and scholarship guides, but no one student will ever qualify for all of them. Even if one person were to qualify for all of them, most students probably would not have the time to apply for each and every one. For this reason, a well-defined scholarship search can be invaluable to students looking for some extra money to fund their education.The best and cheapest way to run a scholarship search is to find a good, reliable scholarship search engine (like fastweb.com or srnexpress.com). Internet searches are free (do not ever pay a fee for scholarship searches, instead use that money towards your education), and unlike scholarship guides that simply list awards, even when they are sorted by subject matter, the internet can h...

Calibration of an orientation sensor for freehand 3D ultrasound and its use
2008-01-24 15:25:00 AUTHORS : James Housden , Graham M Treece , Andrew H Gee and Richard W Prager Abstract (provisional)BackgroundFreehand 3D ultrasound is a powerful imaging modality with many potential applications. However, its reliance on add-on position sensors, which can be expensive, obtrusive and difficult to calibrate, is a major drawback. Alternatively, freehand 3D ultrasound can be acquired without a position sensor using image-based techniques. Sensor less reconstructions exhibit good fine scale detail but are prone to tracking drift, resulting in large scale geometrical distortions.MethodWe investigate an alternative position sensor, the Xsens MT9-B, which is relatively unobtrusive but measures orientation only. We describe a straightforward approach to calibrating the sensor, and we measure the calibration precision (by repeated calibrations) and the orientation accuracy (using independent orientation measurements). We introduce algorithms that allow the MT9-B potentially to correct bot... More About: Orientation

CONFOCAL LASER SCANNING MICROSCOPY
2008-01-22 11:55:00 Confocal laser scanning microscopy (CLSM or LSCM) is a technique for obtaining high-resolution optical images. The key feature of confocal microscopy is its ability to produce in-focus images of thick specimens, a process known as optical sectioning. Images are acquired point-by-point and reconstructed with a computer, allowing three-dimensional reconstructions of topologically-complex objects.DESCRIPTIONIn a confocal laser scanning microscope, a laser beam passes through a light source aperture and then is focused by an objective lens into a small (ideally diffraction limited) focal volume within a fluorescent specimen. A mixture of emitted fluorescent light as well as reflected laser light from the illuminated spot is then recollected by the objective lens. A beam splitter separates the light mixture by allowing only the laser light to pass through and reflecting the fluorescent light into the detection apparatus. After passing a pinhole, the fluorescent light is detected by a pho... More About: Laser , Scanning , Microscopy
