Abstract
PICS (portable imaging computer software), is a software system designed for handling and processing a variety of types of medical image. It has been designed to satisfy the following criteria: (a) the software should be portable between different items of hardware with minimal alteration: (b) there should be a simple operator interface to enable use by inexperienced users, while avoiding the need for experienced users to be directed through tedious menu trees; (c) the programming environment should enable simple integration of new data handling protocols. To meet these requirements the software was written in FORTRAN using structured subroutine organization. The software has basic image handling and processing facilities and contains a comprehensive set of nuclear medicine clinical protocols. Other facilities include alignment of images from different modalities with display of superimposed images and ability to handle, analyse and display three-dimensional data sets. Data transfer programs have been written to capture data from gamma camera, CT, AMI, ultrasound and radiographs by converting the images to a common data format. The system provides a hospital with a central digital image handling resource, enabling investigation of the value of digital image processing in potential clinical applications.
