Paper Abstract

A series of studies were carried out to determine the accuracy of transcribing feature locations in a 'reference’ mammogram to a scaled, and sometimes simplified 'copy’ of the same image. A computer monitor displayed two images of a mammogram. The reference image of the mammogram was presented at 256 colors (greyscale) and, adjacent to this, the copy image was presented with height and width scaled to 0.25, 0.50 or 0.75 of the original, and in one of four forms: blank image, outline, 16 colour palette, and 256 color palette. Participants were required to locate a target on the reference image and indicate its location on the copy image. Results demonstrated accuracy in transcription of target location increased with enhanced image detail and scale. Consequently, it is possible to determine which image characteristics are important in situations where a small representational image is used to record patient information, such as the user interface for a tablet device used to record breast screening decisions.
