Изградња прегледача дицома метадата у Ц #: комплетан туториал | File Format Processing Plugins for C# .NET Core

Разумевање садржаја ДИЦОМ датотеке је од суштинског значаја за развој медицинске слике, решавање проблема и осигурање квалитета. Овај туториал вам показује како да изградите свеобухватни прегледач метаданих података у Ц # који извлачи и приказује информације о пацијентима, детаље студије и техничке параметре за слику.

Šta je DICOM Metadata?

ДИКОМ датотеке садрже две главне компоненте: пикселни подаци (реалну слику) и метадане (информације о слици).

Демографија пацијента: име, идентификатор, датум рођења, пол
Информације студије: датум, време, опис, референтни доктор
Детаљи серије: Модалитет, део тела, протокол за сликање
Параметри слике: Димензије, пикселни простор, подешавања прозора / нивоа
Информације о опреми: Произвођач, модел, софтверска верзија

Мета-датови гледач помаже програмерима да инспектирају ове атрибуте за дебагирање, валидацију и анализу података.

Екстракција основних метадата

Почните са екстракцијом уобичајених атрибута Дицома:

Закључак

Изградња ДИЦОМ метада гледаоца вам даје неопходне могућности за развој медицинске слике. Без обзира да ли вам је потребан брз инспектор командне линије, веб АПИ за интеграцију, или алат за извештавање бацх, Аспасе.Медицински за .НЕТ пружа основу за извлачење и анализу атрибута. Ове технике су вредне за решавање проблема, осигурање квалитета и изградњу медицинских апликација за слику.
