PENGEMBANGAN PROGRAM PENGOLAHAN CITRA UNTUK RADIOGRAFI DIGITAL

Telah dikembangkan sebuah program pengolahan citra untuk radiografi digital yang disusun menggunakan perangkat lunak Borland C++ Builder 4 Professional. Untuk melakukan pengolahan terhadap citra radiografi digital,dengan pengolahan terhadap pixel-pixel dari citra. Teknik pengolahan citra, meliputi pengaturan kecerahan citra (image brightness), kontras citra (image contras), pelembutan citra (image smoothing), penajaman citra (image sharpening), deteksi tepi (edge detection), citra negatif (negative image), dan histogram. Hasil pengolahan citra dihasilkan citra radiografi digital yang mudah  diinterprestasi  lebih  teliti  oleh  pengamat.  Tujuan penelitian ini adalah mendesain perangkat lunak pengolahan citra radiografi digital. Perangkat yang telah disusun kemudian digunakan untuk melakukan pengolahan terhadap citra radiografi digital. Hasil penelitian menunjukkan adanya peningkatan kualitas citra radiografi digital, sehingga dapat membantu seorang radiographer dalam mendiagnosa atau menginterprestasikan citra radiografi digital lebih teliti. Citra radiografi awal dan citra hasilnya dapat dilihat pada layar monitor sehingga  kualitas  pengolahan  dapat dibandingkan secara langsung. The image processing program has been developed for digital radiography that is designed by using software Borland C++ Builder 4 Professional to process the radiography digital image with image pixels processing. Image processing technique consists of image brightness, image contrast, image smoothing, image sharpening, edge detection, and negative image and histogram. From the result of image processing it produced radiography image that is easier to interpret by the observer. The purpose of this research is to design the software of image processing for digital radiography. Then the software is used as the image processor for digital radiography. The result shows that there is a quality improvement of digital radiography image, so it can help the radiographer to diagnose or interpret the detail radiography image. We also can see the radiography image and its result in the monitor screen and compare the quality of processing directly.
