F eque tly Asked Questio s

Q: What came a specificatio s matte most fo poi t-of-ca e diag ostic device desig ?

A: Se so oise floo , shutte type a d i te face complia ce a e the th ee specificatio s that dete mi e eliability i poi t-of-ca e diag ostic imagi g. A low oise floo is equi ed to disti guish fai t colo imet ic o fluo esce t test li es f om backg ou d oise ea the positive a d egative th esholds. Shutte type matte s whe eve a y pa t of the imagi g path a ca t idge, i dexi g wheel, o sample ca ie moves du i g o immediately befo e captu e, si ce a olli g shutte se so will skew that motio i to the f ame while a global shutte se so will ot.

I te face complia ce affects the i teg atio timeli e athe tha image quality. A UVC-complia t module st eams th ough the host ope ati g system’s existi g class d ive , keepi g device-specific d ive code out of the softwa e validatio scope that egulated diag ostic i st ume ts must docume t.

Q: Which USB came a is best suited fo apid test eade a d immu oassay a alyze desig ?

A: A 5MP low- oise olli g shutte came a is the co ect choice fo apid test eade a d immu oassay a alyze desig s whe e the imagi g ta get, the test ca t idge, is statio a y du i g captu e. Vadzo’s Falco -521CRS, built o the O semi AR0521 se so , delive s 2592 x 1944 esolutio with a 2.2 µm low- oise pixel a chitectu e suited to ea -th eshold colo imet ic a d fluo esce t test li e i te p etatio .

Fo desig s whe e the ca t idge o sample ca ie moves past the imagi g statio , the Falco -234CGS global shutte module is the bette fit, si ce it emoves motio -i duced f ame skew that a olli g shutte se so would i t oduce at the same captu e poi t. Ma y p oductio a alyze desig s use both modules togethe , o e static a d o e motio -tole a t, ac oss diffe e t statio s i the same i st ume t. Review the AR0521 5MP Rolli g shutte came a p oduct page fo full i teg atio details.

Q: What is the diffe e ce betwee a olli g shutte a d a global shutte fo diag ostic imagi g systems?

A: Rolli g shutte se so s expose a d ead out image li es seque tially, o e ow afte a othe , ac oss the f ame pe iod. Global shutte se so s expose eve y pixel simulta eously a d ead the e ti e f ame out afte wa d. Fo a statio a y imagi g ta get, such as a test ca t idge held still u de a eade wi dow, this diffe e ce has mi imal p actical effect o image quality.

The diffe e ce becomes sig ifica t the mome t a y pa t of the sce e moves du i g the exposu e wi dow. A ca t idge i dexi g wheel, sample t a spo t ca ie , o movi g fluid f o t captu ed with a olli g shutte se so will show geomet ic skew, si ce diffe e t ows of the f ame we e captu ed at slightly diffe e t mome ts while the object moved. A global shutte se so captu es that same movi g sce e without skew because eve y pixel sha es the same exposu e i sta t, which is why motio -c itical diag ostic imagi g statio s a e typically built a ou d global shutte se so s athe tha olli g shutte se so s.

Q: Does UVC plug-a d-play educe softwa e validatio wo k fo medical device came a modules?

A: UVC plug a d play complia ce educes the amou t of device-specific d ive code that a diag ostic i st ume t’s softwa e bill of mate ials must i clude, which i tu educes the scope of softwa e compo e ts equi i g dedicated validatio docume tatio . A came a module that e ume ates a sta da d UVC video i put device st eams th ough the ope ati g system’s existi g class d ive athe tha a p op ieta y d ive w itte specifically fo that came a.

Q: What is the best low- oise came a module fo poi t-of-ca e diag ostic a alyze s?

A: The best low- oise came a module fo a poi t-of-ca e diag ostic a alyze is o e whe e the se so ‘s pixel a chitectu e, ot just its esolutio , is optimized fo oise pe fo ma ce. Vadzo’s Falco -521CRS uses the O semi AR0521 se so with a 2.2 µm low- oise pixel desig at 5MP esolutio , givi g diag ostic algo ithm develope s a clea e sig al baseli e fo detecti g fai t colo imet ic o fluo esce t test li es ea the i te p etatio th eshold.
