Abstract
Bolesti dišnog sustava najcešce su bolesti u djetinjstvu, a pregledna i profilna rentgenska snimka pluca i snimka sinusa najcešce su radiološke dijagnosticke metode u svakodnevnoj klinickoj praksi u bolnici koja se bavi dijagnostikom respiratornih oboljenja u djece. Zadnjih godina poceli su se primjenjivati digitalni rentgenski sustavi, koji omogucavaju dobivanje digitalnih rentgenskih slika visoke razlucivosti. Razvojem telemedicine i teleradiologije omogucen je prijenos takvih slika putem Interneta, odnosno intraneta. Kako bi se smanjila kolicina podataka digitalnih rentgenskih slika, na njih se mogu primijeniti postupci kompresije. Pri tome parametri kompresije trebaju biti pažljivo odabrani, kako bi se u potpunosti ocuvala vizualna kvaliteta izvorne slike te kako parametri sustava za kompresiju ne bi imali utjecaja na tocnost postavljanja dijagnoze. Buduci da postupak odabira parametara sustava za kompresiju ovisi o sadržaju slike, u radu su obradeni digitalni radiogrami pluca i sinusa u djece. Nad radiogramima komprimiranim JPEG i JPEG2000 algoritmima kompresije mirnih slika, pri razlicitim stupnjevima kompresije, provedeno je objektivno vrednovanje kvalitete slika odredivanjem srednje kvadratne pogreške i vršne vrijednosti omjera signal/šum te subjektivna ocjena kvalitete u kojoj su sudjelovali lijecnici specijalisti. Prikazani rezultati objektivnog i subjektivnog ispitivanja kvalitete komprimiranih slika obradeni su statisticki radi utvrdivanja stupnja korelacije izmedu objektivnih i subjektivnih mjera kvalitete.
Abstract (english)
Respiratory system diseases are the most frequent diseases among children, and X-ray images of lungs and sinuses are the most common radiological diagnostic methods in daily clinical praxis of children hospitals that diagnose respiratory diseases. During last several years radiologists started using digital X-ray systems, which provide aquisition of high resolution digital X-ray images. Development of telemedicine and teleradiology enabled transmission of those images over Internet and intranet. In order to decrease bandwith used in transmission, different image compression techniques can be applied. Compression parameters have to be chosen very carefuly, so that visual quality of the original image is entirely maintained, and that they don't affect final diagnostic accuracy. Due to the fact that selection of image compression parameters depend on the image contents, digital X-ray images of children lungs and sinuses were treated in the paper. Picture quality of those images compressed using JPEG and JPEG2000 algorithms with different compression ratios was evaluated using usual means of objective (Mean Square Error and Peak Signal-to-Noise Ratio) and subjective (conducted by physicians) measures of quality. Presented results of objective and subjective quality of compressed images were treated statistically to determine correlation ratio between objective and subjective quality measures.
