Pler radar software system to measure the patient's breathing, for a precise, gated (targeted) radiation delivery. viagra original kaufen viagra online The patient’s ct scan is used to calibrate the device and guide the linear accelerator (linac) that delivers x-rays to the tumor. The beam is fixed, delivers a high density radiation dose to the tumor as it moves, and minimizes exposure of healthy tissue and the associated severe radiation side effects of current treatments. generic viagra viagra 10 mg canada This radar respiration monitor overcomes the risks and challenges of current respiration-gated, radiation treatments that require invasive implanted reference markers or infrared cameras, and aren't accuracy because of the motion of a floating tumor and the patient's breathing. low price viagra canada buy viagra online Lung tumors can move significantly, making it very difficult for these techniques to deliver a sufficient radiation dose without damaging the surrounding healthy lung tissue. viagra buy cheap viagra Test results showed that the radar-based system was able to supply reliable breathing motions and accurate gating signals for treatment of mobile tumors. viagra for sale cheap buy cheap viagra The wireless radar signal that sends the tumor information back to a computer proved to be more sensitive and more accurate than current treatments that rely on reference markers inserted inside or near the tumor. buy generic viagra   applications cancers that present with floating tumors radiation treatment that needs to account for a patient's respiration advantages this software-defined radar respiration monitor for respiratory-gated radiotherapy: offers a unique software method for live accurate tracking of mobile tumors, specifically in lung cancer, using a non-contact doppler radar avoids the invasive implantation procedure that can cause various side effects such as pneumothorax, bleeding/lung collapse, infections, respiratory failure requiring ventilator support, vasovagal reaction causing cardiac arrhythmias, and even death guides the linac to deliver high-energy x-rays to a patient’s tumor, no matter where it is in the body does not employ any kind of marker, so there is no discomfort at all and it is totally non-invasive is built with commercial integrated-circuit chips at a low cost of approximatley $100 is the most accurate method for tracking tumors penetrates through clothing and tracks muscle movement and bones additional information     categories engineering & physical sciences life sciences software & information technology engineering & physical sciences sensors & controls life sciences diagnostics / imaging life sciences medical devices software & information technology algorithms software & information technology health it inventors changzhi li, professor electrical and computer engineering managers ryan reber ryan.
