Kujambula kwa Magnetic Resonance Imaging (MRI) ndi ukadaulo wojambula wosasokoneza womwe umapanga zithunzi zatsatanetsatane zamitundu itatu. Nthawi zambiri amagwiritsidwa ntchito pozindikira matenda, kuzindikira, komanso kuyang'anira chithandizo.

Makina ojambulira a MRI ndi oyenerera kwambiri kufanizira ziwalo zopanda mafupa kapena zofewa za thupi. Amasiyana ndi computed tomography (CT), chifukwa sagwiritsa ntchito ma radiation owononga a x-ray. Ubongo, msana ndi mitsempha, komanso minofu, mitsempha, ndi tendon zimawoneka bwino kwambiri ndi MRI kusiyana ndi ma x-ray ndi CT nthawi zonse; Pachifukwa ichi MRI nthawi zambiri imagwiritsidwa ntchito pojambula mawondo ndi mapewa.

Muubongo, MRI imatha kusiyanitsa pakati pa zinthu zoyera ndi imvi komanso ingagwiritsidwe ntchito pozindikira ma aneurysms ndi zotupa. Chifukwa MRI sigwiritsa ntchito ma x-ray kapena ma radiation ena, ndiye njira yojambula yosankha pamene kujambula pafupipafupi kumafunikira kuti adziwe matenda kapena chithandizo, makamaka muubongo.

Ma MRIs amagwiritsa ntchito maginito amphamvu omwe amapanga mphamvu yamaginito yomwe imakakamiza ma protoni m'thupi kuti agwirizane ndi gawolo. Magnet ndiye gawo lalikulu la dongosolo la MRI, ndipo mphamvu yake ya maginito, kukhazikika, komanso kufanana kumakhudza kwambiri zithunzi za MRI.

Maginito okhazikika opangidwa ndi CSJ, omwe angagwiritsidwe ntchito poyang'ana thupi lonse, amatengera zida za maginito zosawerengeka zapadziko lapansi, mawonekedwe oponderezedwa a eddy, amakonza mawonekedwe a maginito, amakhala malo ang'onoang'ono, otsika mtengo, ndipo ali ndi digiri yayikulu. za kutseguka, kukonza dongosolo lochepa komanso ndalama zoyendetsera ntchito.
