InterView™ XP processing software

Planar, Whole Body & SPECT processing software

InterView™ XP is an organ-specific dedicated planar, whole-body, and SPECT evaluation software. Procedures are implemented in correspondence with the guidelines of the most acknowledged nuclear medicine societies. The evaluation process is guided through standardized evaluation steps, and supported by specialized viewers and automated algorithms. A wide range of function-specific tools enable the measurement, manipulation, enhancement, and analysis of gamma camera images. User-defined procedure variants allow customization of the workflow. InterView™ XP features 2D and 3D iterative reconstruction of SPECT images, including Mediso-developed Tera-Tomo^TM reconstruction incorporating a full scale of corrections.
