Latar Belakang : Fraktur tulang merupakan kondisi yang membutuhkan penanganan yang cepat. Penegakan diagnosisnya membutuhkan pemeriksaan penunjang foto polos, tapi persebaran spesialis radiologi di Indonesia tidak memadai, maka muncul gagasan penggunaan teleradiologi. Teleradiologi harus menggunakan perangkat pencitraan yang baik sehingga gambar yang dihasilkan tidak nantinya menimbulkan kesalahan interpretasi. Tujuan : Mengetahui perbedaan kualitas citra dan kesesuaian diagnosis antara film hard copy dengan soft copy hasil digitizer dan soft copy hasil kamera saku pada foto polos trauma tulang ekstremitas atas. Metode dan Material : Penelitian observasional pada foto polos trauma tulang ekstremitas atas. Data digital work station di print menggunakan laser printer menghasilkan hard copy yang kemudian didigitalisasi menggunakan digitizer dan kamera saku. Kualitas citra hard copy dibandingkan dengan kualitas citra soft copy hasil digitalisasi menggunakan digitizer dan kamera saku. Hasil : Kualitas citra soft copy hasil digitizer tidak memiliki perbedaan bermakna dibanding hard copy (p=1.000) sedangkan soft copy kamera saku berbeda bermakna dibanding hard copy (p=0.000). Kesesuaian diagnosis antara hard copy dengan soft copy hasil digitizer maupun soft copy hasil kamera saku tidak menunjukkan perbedaan yang bermakna secara statistik (p=1.000). Kesimpulan : Kualitas citra soft copy digitizer setara dengan hard copy, namun kualitas citra hard copy lebih baik dari soft copy kamera saku. Terdapat kesesuaian diagnosis pada ketiga kelompok sampel.

Background : Fracture of upper extremity is an emergency situation which need a quick treatment. The diagnose could be done by running a supporting examination, which is radiology. Indonesia only have for about 700 radiologist which distributed unevenly, therefore teleradiology is needed. Teleradiology needs an imaging device which could produce a good quality image, so there will be no misinterpretation on the reading process. Objective : Understanding the quality differences and diagnose of hard copy film and soft copy file of digitizer and pocket camera of plain upper extremity fracture x-ray. Method and Material : This is an observational research, using 34 samples of plain upper extremity fracture x-ray. The digital data from work station is being printed using a laser printer into hard copy form, then the hard copy film is being digitalized using digitizer and pocket camera. The image quality of soft copy files of digitizer and pocket camera are being compared with the hard copy. Result : There were no significant differences of image quality among hard copy film and soft copy file of digitizer (p=1.000), buat there were significant differences among hard copy film and soft copy file of pocket camera (p=0.000). There were no significant differences of diagnose among hard copy film and soft copy file of digitizer and pocket camera (p=1.000). Conclusion : Image quality of soft copy file of digitizer is equal with hard copy film quality, and hard copy film image quality is better than soft copy file of pocket camera. The diagnose of the three sample groups have uniformity.
