26 The Future is Full of Possibilities u Optical Biopsy u Laser Computed Tomography u 3D Ultrasound u Laser Fluorescence u Computer-based FOTI

27 Computer Aided Diagnosis (CAD) u Observational Errors u Misinterpretation Errors u Integration of Data Errors u Most Beneficial in Observational Errors

28 “CAD systems do not necessarily have to be better than the clinician, just help him not miss obvious lesions.”

29 Computer Aided Diagnosis (CAD) u PAP Cytology & Oral Brush Biopsy u Mammography u Chest X-ray Screening u Periodontal Disease u Dental Caries

32 Digital Dental Imaging u Intra-oral Radiography u Panoramic Radiography u Cephalometric Radiography u Tomography u Intra-oral Photography u Extra-oral Photography u Histology & Surgical Microscopy

33 Interoperability ????????

34 The DICOM Standard The Digital Imaging and Communications in Medicine (DICOM) Standard is a detailed specification that describes semantics and syntax for exchanging images and associated information. The standard applies to the operation of the interface which is used to transfer data in and out of an imaging device.

35 DICOM Workflow DICOM Archive Storage, Query/Retrieve, Study Component Query/Retrieve, Patient & Study Query/Retrieve Results Management Print Management LiteBox DICOM Display Workstation Media Exchange DICOM Acquisition

36 What is DICOM u Digital Imaging and Communication in Medicine u Standard for communication of images and image related information between devices u International in scope u All biomedical imaging u Voluntary standard

37 DICOM is Biomedcial Informatics u “the storage, retrieval, sharing, and optimal use of biomedical information, data, and knowledge for problem solving and decision making.” Edward Shortliffe u “model formation, implementation of the model, application of implementaion to the real world, evaluation of the implementation” Titus Schleyer

38 DICOM, Informatics, Research u Digital X-ray u Visible Light u Clinical Trials u Structured Reporting

39 The Future is Full of Possibilities
