Tsiku lililonse mumagwiritsa ntchito zinthu zomwe zimagwiritsa ntchito mawonekedwe a wavelengths osiyanasiyana kuchokera ku magetsi a magetsi . Zonsezi zapakati pazitsulo zimapereka mphamvu monga mawonekedwe a electromagnetic radiation (EMR). Timagwiritsa ntchito mphamvu izi tsiku lililonse kuphatikizapo (kuyambira mafunde otalika kufikira mafunde ofupika):
- Mafunde a Radiyo - Ma wailesi a FM / FM
- Microwave - yambitseni chakudya kuchokera usiku watha kapena pangani mapulogalamu
- Kusokoneza - njira zambiri zakutali, magetsi otentha
- Zowoneka - zimatithandiza kuona mitundu yosiyanasiyana
- Ultraviolet - kumbuyo kwa dzuwa ku nthawi yachilimwe
- X-ray - zothandiza pa zamankhwala kuti muwone mkati mwa thupi
- Gamma-ray - imathandizanso pa kujambula kwachipatala
X-ray ndi imodzi mwa mawonekedwe a magetsi opangira magetsi omwe angagwiritsidwe ntchito kutenga chithunzi cha mkati mwa thupi. Makina a X-ray amatumiza tizilombo tating'onoting'ono, zomwe zimadutsa mwa zonse koma zinthu zolimba kwambiri monga mafupa ndi chitsulo, kupanga chithunzi chapadera chotchedwa radiograph . Mitsinje ndi zinthu zina zitsulo zidzawoneka zoyera pa radiograph. Minofu, madzimadzi, ndi mafuta zidzawoneka ngati imvi pa chithunzi, pamene mpweya udzawoneka wakuda. Chithunzi choda ndi choyera chomwe chimalengedwa chimapanga chithunzi chomwe chingathandize kwambiri madokotala pakuthandizira kudziwa momwe mukugwiritsira ntchito mankhwala.
Mavuto Ogwirizana ndi X-Ray
Kukhala ndi x-ray sikumvetsa chisoni, koma ngati kachitidwe kawirikawiri, kukhoza kukhala ndi chiopsezo chokhala ndi khansara kenaka m'moyo.
Zowopsazi ndizochepa kwambiri ndipo ziyenera kuyesedwa phindu lokhala ndi zithunzi. Ndikofunika kwambiri kuti udziwitse akatswiri a x-ray ngati uli ndi pakati.
Zomwe zimagwiritsidwa ntchito pangozi chifukwa cha kuwala kwa dzuwa zimakhala zowerengeka kuchokera ku opulumuka mabomba a atomiki ku Japan kuchokera mu 1945. Kuti mumvetse bwino izi, mau awiri ndi ofunika kwambiri.
Roentgens ndi mawu omwe amagwiritsidwa ntchito kufotokoza kuchuluka kwake kwa mphamvu ya mpweya mu mpweya. Dzinali limatchulidwa ndi amene anayambitsa x ray, Wilhelm Roentgen, mu 1895. Mlingo woyenera umayesedwa mu sieverts (Sv) yomwe imatanthauzira mozizwitsa thupi lonse la miyezi. Kupitirira chiwerengerocho, pamene mumalandira ma radiation kwambiri.
Pali kusiyana kwakukulu kwa momwe chiopsezo chachikulu chokhalira ndi khansa chimawonekera chifukwa cha kutuluka kwa dzuwa, komabe, kuyerekezera kwa CT kukuwoneka kuti ndi kotheka kwambiri. X-ray imodzi imakhala ndi mafunde ochepa ndipo nthawi zambiri imakhala yozungulira miyandamiyanda 200 (mSv). Kansalu ya CT imatha kuchokera ku 2 mSv (Head CT) kufika pa 16 mSv (Coronary CT Angiogram), yomwe ili yofanana ndi 100 mpaka 800 x-ray.
Zimene muyenera kuyembekezera X-Ray
Mungapemphedwe kuvala chovala chachipatala ndikuchotsa zodzikongoletsera zomwe mukuvala chifukwa zidzasonyezedwa pa x-ray. Malingana ndi dera limene mukuganiza kuti mukhoza kujambula mungapemphedwe kuti azikhala m'malo osiyanasiyana, ena mwa iwo angakhale ovuta. Komabe, zimangotenga kachiwiri kuti mutenge x-ray, kotero izi ndi zosakhalitsa. Ndiponso, malingana ndi malo omwe mukujambula nawo, wothandizira angatenge ma shoti angapo kuchokera kumbali zosiyanasiyana. Zithunzizo kawirikawiri zimamasuliridwa ndi dokotala wotchedwa radiologist, yemwe amadziwika bwino pofufuza mayesero awa.
Zotsatira zimatumizidwa kwa dokotala wanu.
Kodi Ngoziyi Ndi Wofunika Kwambiri?
Ndikofunika kuti mukambirane ndi dokotala wanu . Muyenera kufunsa nthawi zonse, "Kodi kufufuza kwa x-ray kapena ct kumathandiza bwanji?" Ngati phunziro la kujambula silikutha kusintha zinthu, mwinamwake ndibwino kuti muyambe kuyesa. Komabe, ngati mankhwala angasinthe malinga ndi zotsatira za x-ray kapena CT, ndiye kuti ziyenera kukhala zochepa.
