ViewDex

ViewDEX (Viewer for Digital Evaluation of X-ray images) utvecklas i ett samarbete mellan Södra Älvsborgs Sjukhus, Sahlgrenska Universitetssjukhuset och Göteborgs universitet. Arbetet startade med syfte att ta fram en mjukvara som enkelt kunde användas för att genomföra granskningsstudier inom bild- och funktionsmedicin. Idag hanterar ViewDEX merparten av alla DICOM-datatyper och registrerar under en studies utförande givna svar och data (ex granskningstid, valfritt DICOM-element och fönstersättningar).

Programmet är utvecklat i Java (Sun Microsystems, Santa Clara, CA, USA). Bildhanteringen baseras på grafik- och bildhanteringsbiblioteken Java 2D och Java Advanced Imaging (JAI). Programmet kan köras från hårddisk, usb-minne eller annan extern hårddisk.

ViewDEX administreras och konfigureras genom att editera de olika textfiler som styr enskilda studier och användare (så kallade property-filer). I dessa definierar man uppgifter (frågor och svarsalternativ) och funktionalitet (zoom, interpoleringstyp, cineloop, etc). ViewDEX läser de flesta DICOM-datatyperna och bilder kan lagras på godtyckligt datamedium anslutet till datorn. För varje studie lagras resultaten från respektive granskare i en log-fil. Denna fil används sedan som indata för vidare analys av resultaten (ex i excel). ViewDEX hanterar free-response ROC, standard ROC och visual grading-studier, liksom kombinationer av dessa. Utöver detta kan programmet också användas i undervisningssyfte och för benchmarking.

Tillgång till ViewDEX
Programmet är fritt att använda för icke-kommersiellt bruk. Referera till Svalkvist et al. (Radiat. Prot. Dosimetry 2016), Håkansson et al. (Radiat. Prot. Dosimetry 2010) och Börjesson et al.
