Abstrak :
Fotografi merupakan bagian terintegrasi standard prosedur pemeriksaan forensik dan dapat berperan sebagai petunjuk, keterangan pengganti barang bukti maupun sebagai barang bukti itu sendiri. Dokumentasi fotografi forensik memiliki tujuan menghasilkan gambar yang berkualitas dan akurat. Akurasi gambar dapat dinilai dari kesesuaian antara keadaan sebenarnya (atau setidaknya mendekati) saat pengambilan gambar dan pemeriksaan dilakukan oleh dokter pemeriksa dengan interpretasi orang lain yang melihatnya di waktu yang berbeda. Hasil studi observasional potong lintang menggunakan 55 sampel penelitian gambar digital kamera DSLR didapatkan panjang fokal lensa 50mm memiliki hubungan bermakna (p < 0,05). Sedangkan rentang nilai bukaan lensa (f7,1-f8,0), kecepatan rana (1/100 detik-1/125 detik) dan sensitivitas sensor (ISO = 800-1600) dengan penggunaan cahaya tambahan flashlite dapat dijadikan acuan dasar settingan kamera digital pada pemeriksaan genitalia kasus kekerasan seksual pada anak saat ini. Selain itu, didapatkan kesesuaian keseluruhan interpretasi sedang antara dua ahli forensik (k = 0,457), kesesuaian interpretasi pada area labia minor masih dapat diterima (k = 0,238) dan fourchette posterior (k = 0,230), serta kesesuaian interpretasi kuat pada area hymen (k = 0,643). ......Photography is an integrated part of standard forensic examination procedures and can act as a guide, substitute information for evidence as well as evidence itself. Forensic photography documentation aims to produce quality and accurate images. Image accuracy can be assessed from the conformity of the actual situation (or at least approaching) when shooting an image and doctors examinations with the interpretation of other people who see it at different times. The results of a cross-sectional observational study using 55 DSLR camera digital image research samples obtained that 50mm lens focal length had a significant relationship (p <0.05). While the range of lens aperture (f7,1-f8,0), shutter speed (1/100 seconds-1/125 seconds) and sensor sensitivity (ISO = 800-1600) with additional use of flashlite can be used as a basic reference for digital camera settings on child sexual violence cases examination. In addition, it was found that the overall interpretation conformity was moderate between two forensic experts (k = 0.457), interpretation conformity could still be fair in the minor labia (k = 0.238) and posterior fourchette (k = 0.230), also substantial in the hymen (k = 0.643).

Abstrak :
A state-of-the-art review of key topics in medical image perception science and practice, including associated techniques, illustrations and examples. This second edition contains extensive updates and substantial new content. Written by key figures in the field, it covers a wide range of topics including signal detection, image interpretation and advanced image analysis (e.g. deep learning) techniques for interpretive and computational perception. It provides an overview of the key techniques of medical image perception and observer performance research, and includes examples and applications across clinical disciplines including radiology, pathology and oncology. A final chapter discusses the future prospects of medical image perception and assesses upcoming challenges and possibilities, enabling readers to identify new areas for research. Written for both newcomers to the field and experienced researchers and clinicians, this book provides a comprehensive reference for those interested in medical image perception as means to advance knowledge and improve human health.
