Bloch Simulator

Mayelana nalolu hlelo lokusebenza

I-Bloch Simulator yamahhala ikuvumela ukuthi uhlole amasu anhlobonhlobo we-Magnetic Resonance (MR) asetshenziselwa i-NMR ne-MRI (Nuclear Magnetic Resonance and Magnetic Resonance Imaging). Lezi zindlela zibaluleke kakhulu ekucabangeni kwezokwelapha nasekuhlaziyweni ngamakhemikhali. Ziyakwazi ukuzivumelanisa nezimo kepha ziyinkimbinkimbi ngandlela thile. I-simulator yenzelwe ukufundisa nokufunda lezi zihloko ezibandakanya ukuhamba kwe-3D yezindawo zokuphehla amandla enuzi, okuyinselele ukuyiqonda nokuyiqonda. Ukubona kusiza kakhulu, futhi kunezela elinye izinga lobuhle kwi-MRI ngale kwezithombe ezinemininingwane ze-MR uqobo. Amavidiyo wesingeniso atholakala ngekhaya le-simulator angakusiza ukuthi uqalise: http://www.drcmr.dk/bloch (isoftware yathuthukiswa kakhulu selokhu amavidiyo aqoshwa, nokho).

Abasebenzisi bokuqala beBloch Simulator ngabafundi nabafundisi be-MR kuwo wonke amazinga. Ingakhombisa imiqondo esukela kwezisekelo ezidingekayo zabo bonke abasebenzisi, emiqondweni esezingeni eliphakeme edingwa abathuthukisi be-MRI. Ngosuku lokuqala lwemfundo ye-MR, i-CompassMR Simulator iyanconywa, kepha iBloch Simulator izokuthatha ikudlule (i-simulators emibili yenziwa ngumthuthukisi ofanayo).

Ama-simulators atholakala zombili njengezinhlelo zokusebenza namakhasi e-inthanethi asebenzayo (http://drcmr.dk/CompassMR, http://drcmr.dk/BlochSimulator). Kusetshenziswa iBloch Simulator esipheqululini esikwi-PC ejwayelekile kunikeza indawo yokuqala engcono yokuhlola, kanti uhlelo lokusebenza olufanayo lufanelekela izivivinyo zomfundi phakathi nezinkulumo, ngokwesibonelo. Kumadivayisi eselula, izinhlelo zokusebenza zinconywe ngokuqinile ngaphezulu kwezinguqulo zewebhu ngoba zenzelwe izikrini ezincane. Buka kwimodi yokuma komhlaba.

Uhlelo lokusebenza liqanjwe ngemuva kwesishoshovu saseSwitzerland-American Nobel u-Felix Bloch (1905-1983) owethule i-equations ye spin spin ukuthi i-simulator ixazulula futhi ibone ngeso lengqondo ngesikhathi sangempela. Phakathi kwemiqondo eboniswe kahle yi-app kukhona ukucashunwa, ukuthandazelwa, ukuphumula, ukudangala, i-gradients, ama-FID, ozimele besethenjwa, ama-spin kanye nama-grayent grayes, ukufaka isisindo, ukumosha, ukugoqa kwesigaba, ukucabanga, nokunye okuningi. Izibonelo zemiqondo esezingeni eliphakeme emema ukuhlola kwe-simulator kufaka phakathi ama-pulses abunjiwe, ukulandelana kwe-SSFP, ukukhethwa kwe-voxel kanye nezimpawu ezivuselelekile. Ngayinye yalezi ingahlaziywa ngezindlela ezahlukahlukene, ekhombisa ukuguquguquka okukhulu kwe-simulator.

Improved control of relaxation properties, mostly.
