- ItemDigital imaging in pathology: the case for standardization.(2005-05-19) Yagi, Yukako; Gilbertson, John RThe process of digital imaging in microscopy is a series of operations each contributing to the quality of the final image that is displayed on the computer monitor The operations include sample preparation and staining by histology optical image formation by the microscope digital image sampling by the camera sensor postprocessing and compression transmission across the network and display on the monitor There is an extensive literature about digital imaging and each step of the process is fairly well understood However the complete process is very hard to standardize or even to understand fully The important concepts for pathology imaging standards are 1 systems should be able to share image files 2 the standards should allow the transmission of information on baseline colours and recommended display parameters 3 the images should be useful to the pathologist not necessarily better or worse than direct examination of a slide under the microscope 4 a mechanism to evaluate image quality objectively should be present 5 a mechanism to adjust and correct the minor errors of tissue processing should be developed 6 a public organization should support pathologists in the development of standards
- ItemWebcasting pathology department conferences in a geographically distributed medical center.(2004-07-16) Yagi, Yukako; Ahmed, Ishtiaque; Gross, William; Becich, Michael J; Demetris, Anthony J; Wells, Alan; Wiley, Clayton A; Michalopoulos, George K; Yousem, Samuel A; Barnes, Barbara; Gilbertson, John RAs academic pathology departments have become increasingly based in large regional medical systems spread across hundreds of square miles new methods are needed to tie these increasingly distributed departments together as integrated units An important part of that integration is the ability to share academic and teaching conferences across long distances In this article we present an effective low cost webcasting system that has evolved at the University of Pittsburgh Medical Center Department of Pathology over the past several years based on inexpensive widely available software To date the system has broadcast and archived more than 400 conferences and currently serves approximately 80 to 100 requests each week Important factors in the success of the program include the creation of a faculty steering committee to control resources and manage growth the availability of informatics faculty and support for technical staff and the decision to operate the service as part of the core information technology infrastructure of the department Webcasting will likely become an even more important academic and operational tool in the future as more of the department s conferences seminars and even working meetings are communicated through the webcasting infrastructure
