Si studente doktorature n\u00eb inxhinieri biomjek\u00ebsore n\u00eb Universitetin e Mi\u00e7iganit n\u00eb SHBA, gjat\u00eb fillimit t\u00eb viteve 2000, Xu po p\u00ebrpiqej t\u00eb gjente nj\u00eb m\u00ebnyr\u00eb q\u00eb mjek\u00ebt t\u00eb shkat\u00ebrronin dhe hiqnin indet e s\u00ebmura pa pasur nevoj\u00eb p\u00ebr kirurgji invazive. Ajo hodhi iden\u00eb e p\u00ebrdorimit t\u00eb val\u00ebve zanore me frekuenc\u00eb t\u00eb lart\u00eb – ultratingujve – p\u00ebr t\u00eb cop\u00ebtuar mekanikisht indet dhe po e testoi teorin\u00eb e saj n\u00eb zemrat e derrave.<\/p>\n
Ultratingujt nuk supozohet t\u00eb jen\u00eb t\u00eb d\u00ebgjuesh\u00ebm p\u00ebr vesh\u00ebt e njeriut, por Xu po p\u00ebrdorte nj\u00eb amplifikator kaq t\u00eb fuqish\u00ebm n\u00eb eksperimentet e saj, saq\u00eb studiues t\u00eb tjer\u00eb me t\u00eb cil\u00ebt ndante laboratorin filluan t\u00eb ankoheshin p\u00ebr zhurm\u00ebn . “Asgj\u00eb nuk kishte funksionuar gjithsesi,” thot\u00eb ajo. K\u00ebshtu q\u00eb vendosi t’i b\u00ebnte humor koleg\u00ebve t\u00eb saj duke rritur shkall\u00ebn e pulseve t\u00eb ultratingujve, gj\u00eb q\u00eb do ta sillte nivelin e z\u00ebrit jasht\u00eb diapazonit t\u00eb d\u00ebgjimit t\u00eb njeriut.<\/p>\n
P\u00ebr habin\u00eb e saj, rritja e numrit t\u00eb pulsimeve n\u00eb sekond\u00eb jo vet\u00ebm q\u00eb ishte m\u00eb pak shqet\u00ebsuese p\u00ebr ata p\u00ebrreth saj, por edhe m\u00eb efektive n\u00eb indet e gjalla sesa qasja q\u00eb kishte provuar m\u00eb par\u00eb. Nd\u00ebrsa shikonte, nj\u00eb vrim\u00eb u shfaq n\u00eb indin e zemr\u00ebs s\u00eb derrit brenda nj\u00eb minute nga aplikimi i ultratingullit. “Mendova se po \u00ebnd\u00ebrroja”, thot\u00eb Xu, e cila sot \u00ebsht\u00eb profesoresh\u00eb e inxhinieris\u00eb biomjek\u00ebsore n\u00eb Universitetin e Mi\u00e7iganit.<\/p>\n
Dekada m\u00eb von\u00eb, zbulimi i rast\u00ebsish\u00ebm i Xu-s\u00eb, i njohur si histotripsi, \u00ebsht\u00eb nj\u00eb nga disa qasje q\u00eb p\u00ebrdorin ultratinguj dhe po sjellin nj\u00eb epok\u00eb t\u00eb re t\u00eb trajtimit t\u00eb avancuar t\u00eb kancerit, duke u ofruar mjek\u00ebve metoda jo invazive p\u00ebr t\u00eb \u00e7liruar pacient\u00ebt nga tumoret kancerogjene duke p\u00ebrdorur tinguj n\u00eb vend t\u00eb kirurgjis\u00eb.<\/p>\n","protected":false},"excerpt":{"rendered":"
