Medical imaging technologies such as magnetic resonance imaging (MRI) and computerized tomographic (CT) are used to diagnose a wide range of medical diseases. Medical images are generated by detecting density differences between different tissues in the body. Multiple medical image visualization is of critical importance to diagnosis. This paper introduces a dual-view medical image visualization prototype based on spatial-temporal psychovisual modulation (STPVM). Temporal psychovisual modulation (TPVM) enables a single display to generate multiple visual content for different viewers. Spatial psychovisual modulation (SPVM) extends the idea of TPVM to spatial domain. STPVM combines TPVM and SPVM by exploiting both temporal and spatial redundancy of modern displays. Based on STPVM technology, one display can present even more images simultaneously. In this demo, two kinds of medical images e.g. T1 and T2 weighted MRI images, are presented simultaneously. Physicians can switch between either image by just moving the eye fixations. Since T1 and T2 are shown simultaneously and are aligned on the screen, it is more convenient for the physicians to get different information of the same spot from the T1 and T2 images. The developed demo is useful for physicians during surgery navigation and effectively reduces the burden of mental transfer.
