Wani sabon binciken ya nuna ingantaccen algorithm wanda zai iya ingantawa sosai yadda masu aikin rediyo ke kamawa da fassara MRI na cikakken jiki, musamman a cikin yankin ciki.

Abubuwan motsi na motsi a cikin MRIs, irin su motsin haƙuri, sau da yawa suna bayyana a matsayin kayan aikin fatalwa waɗanda zasu iya ɓoye bayanan asibiti in ji Dokta Candice Bookwalter, mai gabatar da marubuci don binciken. "Kusan duk abin da aka samu a lokacin jarrabawar ciki na MR yana buƙatar ɗaukar numfashi don iyakance motsi. Misali, jarrabawar hanta ta yau da kullum ta ƙunshi akalla numfashi tara. Ko da tare da fasahar hoto mai sauri, waɗannan numfashin suna da tsawo da wuya ga marasa lafiya, kuma sun kasa. Kusan kusan koyaushe ana gano abubuwan riƙe numfashi ne kawai bayan siyan hoto. Wannan yana da matsala musamman a lokacin daukar hoto bayan bambance-bambancen lokaci, "in ji ta.

Ita da tawagarta sun haɓaka Motion Artifact Removal by Retrospective Resolution Reduction (MARs) algorithm don gano sauye-sauye tsakanin riƙewar numfashi da numfashi kyauta don ba da damar ingantattun sake dubawa na hoton da kuma rage buƙatar ƙarin hoto. Dokta Bookwalter ya ce, "MARs sun gano kuma sun cire bayanan da suka lalace ta atomatik a cikin masu aikin sa kai na mu da marasa lafiya, wanda ya inganta ingancin hoto gaba ɗaya."

A cikin binciken da aka yi a Asibitin Jami'ar a Case Medical Center, Case Western Reserve University, Dokta Bookwalter da abokan aikinta sun yi nasarar nuna yadda fasahar MARs ta ba da damar masu aikin rediyo da masu fasaha don ƙirƙirar hotuna masu amfani da asibiti, ko da a gaban motsi. Tana da tabbacin cewa wannan algorithm zai zama kayan aiki mai amfani don fassarar hoto. Ta ce, "Algorithm na MARs yana buƙatar canji kaɗan na ka'idar MR na asibiti. Muna tsammanin aikace-aikacen ƙarshe na wannan dabarar ta kasance gaba ɗaya ta atomatik kuma mai yuwuwar amfani da fasahar fasaha ta asibiti kafin gabatarwa ga likitan rediyo."

Dr. Bookwalter zai gabatar da gabatarwa akan wannan binciken a ranar Alhamis, Mayu 5, 2011 a taron shekara-shekara na 2011 ARRS a Hyatt Regency Chicago.
