An electrocardiosignal is amplified, detected, and processed by a microprocessor, and then is outputted with a control signal to control the exposing occasion of the X-ray machine, so that the cardiac X-ray images shooting in different periods are at the same cardiac cycle phase, causing to...
The Z machine at Sandia National Laboratory in Albuquerque, N.M., is the world's most powerful man-made x-ray source. In operation, laser-triggered switches release the charge stored in massive capacitor banks to channel 20 MA through an array of small wires, vaporizing them into a plasma...
A heart attack typically lasts from a few minutes to several hours, depending on how severe the blockage is and how quickly medical treatment is administered. The pain or discomfort can vary in duration, but the longer the blockage persists, the greater the damage to the heart muscle. Immediat...
