Po desetilet\u00ed jsme se omezovali na ultrazvuk. \u010ctvrt stolet\u00ed. Tak dlouho dominovala kosmick\u00e9 medic\u00edn\u011b ultrazvukov\u00e1 diagnostika.

Hmotnost. Tepl\u00fd. Z\u00e1\u0159en\u00ed. Nestabilita. V\u0161echno let\u00ed. V\u0161echno vibruje.

Na sc\u00e9nu p\u0159ich\u00e1z\u00ed MinXray TR90B. Je kompaktn\u00ed. Velikost asi jako n\u00e1doba na led. Komer\u010dn\u00ed stupe\u0148. Cenov\u011b dostupn\u00e9 \u0159e\u0161en\u00ed.

Fotografie se uk\u00e1zaly b\u00fdt vysoce kvalitn\u00ed. <\/p>\n

Ale testy na Zemi jsou jen pohodln\u00e1 le\u017e. Vesm\u00edr je skute\u010dn\u00fd test. <\/p>\n

Zde je ale hlavn\u00ed detail: astronauti neabsolvovali m\u011bs\u00edc l\u00e9ka\u0159sk\u00e9ho v\u00fdcviku. <\/p>\n

\u010dty\u0159i hodiny. <\/p>\n

P\u0159edstartovn\u00ed sn\u00edmky zahrnovaly pa\u017ee, p\u0159edlokt\u00ed, hrudn\u00edk, b\u0159icho a p\u00e1nev. Z\u00e1kladn\u00ed ukazatele na Zemi. <\/p>\n

Na ob\u011b\u017en\u00e9 dr\u00e1ze se postup opakoval. Sn\u00edmek kalibrace. Ruka. P\u0159edlokt\u00ed. \u017debra. \u017daludek. Taz. <\/p>\n

Po\u010dkejte. Pro\u010d sundali hodinky? <\/p>\n

Ud\u011blali tak\u00e9 rentgen chytr\u00fdch hodinek. Dok\u00e1zat, \u017ee syst\u00e9m funguje nejen s lidskou tk\u00e1n\u00ed, ale tak\u00e9 s elektronikou. D\u016fle\u017eit\u00e1 je elektronika.

Je pot\u0159eba vid\u011bt zevnit\u0159 \u2013 bez rozeb\u00edr\u00e1n\u00ed. <\/p>\n

Bylo to \u00fasp\u011b\u0161n\u00e9?<\/h3>\n

T\u0159i nez\u00e1visl\u00ed radiologov\u00e9 p\u0159ezkoumali sn\u00edmky po\u0159\u00edzen\u00e9 na ob\u011b\u017en\u00e9 dr\u00e1ze pot\u00e9, co byly p\u0159eneseny na Zemi. <\/p>\n
