Abstract

The ap­pli­ca­tion of the two tec­hno­lo­gi­es: re­ver­se en­gi­ne­e­ring and ra­pid pro­totyping is emer­ging ra­pidly in the me­di­cal ap­pli­ca­ti­ons. The­se en­gi­ne­e­ring met­hods ha­ve espe­ci­ally shown fast advan­ce­ment in the fol­lo­wing ap­pli­ca­ti­ons: in very com­plex pre­pa­ra­tion of com­pu­ter aided sur­gery, com­pu­ter gu­i­ded im­plan­to­logy, non-in­va­si­ve di­ag­no­stic from CT and MRI scans, de­sign of cu­sto­mi­zed im­plants, ma­xil­lo­fa­ci­al sur­gery, est­he­tic and re­con­struc­ti­ve pla­stic sur­gery, ort­ho­pe­dic sur­gery, etc. This re­se­arch has a mul­ti­di­sci­pli­nary ap­pro­ach; it re­qu­i­res a te­am work of ex­perts from va­ri­o­us sci­en­ti­fic fi­elds such as CAD de­sign and vir­tual en­gi­ne­e­ring, di­gi­tal ima­ge pro­ces­sing, me­di­ci­ne, im­plan­to­logy. Only a very few ap­pli­ca­ti­ve pi­o­ne­er steps ha­ve been ma­de so far in Re­pu­blic of Srp­ska, Bo­snia and SE Euro­pe in ge­ne­ral.

The aim of this re­se­arch is to ma­ke a con­tri­bu­tion to the op­ti­mi­za­tion of all three pha­ses: pre­pro­ces­sing, pro­ces­sing and post-pro­ces­sing in the pro­cess chain of re­ver­se en­gi­ne­e­ring – ra­pid pro­totyping in the me­di­cal ap­pli­ca­ti­ons. The op­ti­mal pro­cess of ra­pid pro­totyping has been de­fi­ned for dif­fe­rent me­di­cal in­put da­ta and for­mats. The pro­cess in­clu­des in­ter­nal 3d re­con­struc­tion of CT and MRI scan­ning in DI­COM for­mat, such as ap­pli­ca­ti­ons in ort­ho­pe­dic sur­gery, ma­xil­lo­fa­ci­al sur­gery, prost­he­tic den­ti­stry, such as com­plex or to­tal prost­he­sis, as well as  the ex­ter­nal sur­fa­ce re­con­struc­tion by 3d scan­ning, such as est­he­tic sur­gery and re­con­struc­tion pla­stic sur­gery or den­ti­stry ba­sed on 3d scan­ning from ela­stic si­li­co­ne im­pres­sion.

Keywords: op­ti­mi­za­tion, pre­pro­ces­sing and post-pro­ces­sing, re­ver­se en­gi­ne­e­ring, com­pu­ter gu­i­ded im­plan­to­logy.
