a –pathology in adults,f = 4-7 hz, a = 50 μv delta- at rem sleep f = 1- 4 hz, a = 100 μv ultrasonography- detection of size and shape of foetus in uterus x-ray imaging methods: sciascopy,sciagraphy, classical and computer tomography x-rays: kind of ionizing, non-visible radiation. it is danger for living body. max. harmless exposure is 5 msv/ year -adults source: x-ray tube (diode with - cathode and + ano-de ). electrons are emitted from cathode and flight in vacuum targeting anode. thus, only 1-2% x- ra-ys is produced, 98% is taken away of diode as a heat. there are “hard“ and “soft“types of x-rays. the higher is an anodal voltage (50-150 kv) the har-der (more penetrable) is x-ray radiation and vice versa. x-ray photo is black-white.the bones and air have best contrast, soft tissues have worse or no contrast. the contrast matters must be injected nuclear magnetic …
