Mudzidzi mutsva akabata uye akatanga chirongwa chekugadzira anatomical 3D modhi zvakananga kubva kuX-ray komputa tomographic data seti, izvo zvinogona kubatsira vadzidzi nenyanzvi dzekurapa kuti vanzwisise zvakaomarara bhonzo uye nhengo dzenhengo, uye zvakare kuongorora nekutsvaga zvirwere. Pepa uye zvakare vhidhiyo inoenderana nevatsvaguri, yakanzi "3D Kudhindwa kwePreclinical X-ray Computed Tomographic Data Sets," yakaburitswa muJournal yeVisualized Experiments (JoVE) svondo rino, ichipa yakadzama nhanho-nhanho maitiro ekuita. uchishandisa nhevedzano yemasoftware mapakeji kugadzira nekugadzirisa iwo e3D modhi kubva kuCT scans uye kuratidza zvakabuda 3D-akadhindwa modhi. JoVE inonakidza pachayo sezvo iri yakanakisa PubMed-yakanyorwa sainzi vhidhiyo magazini, inopa mahara-kuwana kune emhando yepamusoro mavhidhiyo anoratidza uye anotsanangura tsvakiridzo mhedzisiro.

Maturusi esoftware uye 3D-madhindi anodiwa kuita iyi maitiro ari kuramba achidhura uye ari nyore kushandisa.

Pfungwa yepurojekiti, iyo yakatangwa mukutanga kwe2012, yakabva panguva iyoyo-mutsva mudzidzi Evan Doney, aishanda parabhoritari yaW. Matthew Leevy, purofesa mubatsiri wekutsvakurudza paNotre Dame Integrated Imaging Facility. "Izano rakangwara," Leevy anodaro. "Akaita zvakawanda akazvimiririra. Akafunga kuti angashandura sei tomographic data kumepu yepamusoro yekugadzirisa uye kudhindwa kwe3D."

Pepa racho rinopedzisa kuti nekuunganidza kwakaringana data, kupa pamusoro, uye stereolithographic editing, zvave kuitika uye zvisingadhure kukurumidza kuburitsa yakadzama skeletal uye yakapfava zvimiro zvetishu kubva kuX-ray CT data. Dudziro yepre-kiriniki ye3D data kuchinhu chinobatika chiri kopi chaiyo yechidzidzo chebvunzo chishandiso chine simba chekuona nekutaurirana, kunyanya chine chekuita nekutsvaga kwekufungidzira kuvadzidzi, kana avo vari mune mamwe mativi.

Mwedzi wapera chete takaputsa nyaya yekuvhiyiwa kwekutanga muU.S. tichishandisa 3D-yakadhindwa dehenya implant, iyo yakagadzirwa nekushandisa data kubva chaiyo X-ray CT scans. Iyo nzira inoratidzwa mubepa razvino haizi pfungwa nyowani kana maitiro, asi yakatogadzirwa uye kushandiswa kubva makore akati wandei, uye padanho repamusoro yakatokura zvekusvika FDA inotenderwa kugadzirwa kwetsika-yakagadzirwa vanhu kudyara, senge. iyo cranial implant yakagadzirwa nekambani Oxford Performance Materials vachishandisa yavo yepamusoro-inoshanda polymer zvinhu PEKK uye EOS laser sintering muchina. Chii chitsva asi ndechekuti maturusi esoftware uye 3D-madhindi anodiwa kuita chirongwa ichi ari kuramba achidhura uye ari nyore kushandisa, kusvika padanho rekuti vadzidzi vari munzvimbo yakajairwa yekutsvagisa vanogona ikozvino kuzvidzidzisa uye kushandisa zvishandiso zviripo kuzviita.

Mirayiridzo yeHOWTO yekushandisa mapakeji esoftware angori mashoma mapeji akareba, ayo anoratidza kuti zvakave nyore sei kuita zvepamberi zvekurapa nekugadzira maitiro - iro basa chairo rekudzokorora zvimiro zveanatomical raitora nguva uye richidhura kusvika zvino. Sezvo maitiro aya achizowedzera hunyanzvi huripo, kuderedza mitengo uye kutungamira mukutsvagisa kwepamusoro uye kubuda kwebudiriro - zvichinyatso kutsanangura kugadzirwa kwepamusoro munzvimbo ino nedzimwe dzakawanda -- chinogona kungove chinhu chakanaka!

3D yakadhindwa modhi yemapapu uye skeletal maficha egonzo X-ray CT data set. Zvinhu zvakadhindwa pachishandiswa ProJet HD 3000 (kuruboshwe), Shapeways Inc. (Center) kana Makerbot Replicator (kurudyi). Chiyero bhaa chinoreva 2 cm. Ziva kuti bhara mupanera C idiki pane iro reA uye B, izvo zvinoratidza kuti mune dzimwe nguva Mugadziri anofanira kudhinda chinhu chakakurisa kuti abudise zvakakwana.

"Chirongwa chedu chine 3-D kudhindwa chikamu chenyaya yakafararira nezve 3-D kudhindwa kwakawanda," Leevy anodaro, achiwedzera kuti basa iri rakaburitsa mamwe mazano nemikana yakawanda, sekupa mhando dzisingadhure dzevadzidzi veanatomy. "Kune musika wemapfupa aya, kubva kumhuka uye kubva kuvanhu, uye tinogona kuasika nemutengo wakaderera zvinoshamisa. Tichaongorora yakawanda yemisika iyi."

Mumwe mubatsiri wekiriniki, Dr. Douglas Liepert kubva kuAllied Physicians of Michiana, ari kugonesa vatsvakurudzi kudhinda data yevanhu vasingazivikanwe, kuwedzera mikana. "Hatisi chete isu tinogona kudhinda chimiro chemapfupa, asi isu tave kutanga kuunganidza data revarwere uye kudhinda chimiro cheanatomical yevarwere vane chirwere chakasiyana nyika kubatsira vanachiremba mukugadzirira kuvhiya," Leevy anodaro.

Chirongwa chekutanga chakashandisa X-ray CT data seti kubva kuLobund-Wistar mhenyu uye kubva padehenya rakachengetedzwa reNew Zealand White Rabbit.
