Indications for Use

InterView XP is an advanced medical image visualization and post-processing Software as Medical Device (SaMD) for clinical applications. InterView XP is specialized for Nuclear Medicine applications focusing on planar, whole body and SPECT evaluations. InterView XP supports SPECT reconstruction. The process of quantitative evaluation is guided through standardized evaluation steps and supported by specialized viewers and automated algorithms. A wide range of function-specialized tools enable measurement, manipulation, enhancement and analysis of medical images. Data from Mediso or third party manufacturer's devices may be passed to the application from the integrated database or other PACS systems. Data handling includes images transfer, storage and printing capabilities of DICOM images. InterView XP is a stand-alone medical software which can operate on dedicated workstations provided by the manufacturer. InterView XP is NOT intended to be used as a replacement for visual interpretation nor as a diagnostic tool without other clinical and laboratory information. It is not intended to treat the patient, to monitor vital signs or to give a direct diagnosis of disease.

Device Story

InterView XP is a standalone DICOM-compatible SaMD for nuclear medicine image visualization and post-processing. It processes planar and tomographic (SPECT) scans acquired by gamma cameras. The software provides tools for image display, manipulation, enhancement, analysis, and quantification. It operates on Windows-based workstations. Clinicians and technicians use the software to review images and perform quantitative evaluations guided by standardized steps and automated algorithms. The device provides diagnostic information to support clinical decision-making but is not a replacement for visual interpretation or a standalone diagnostic tool. It does not control image-generating hardware. Benefits include standardized analysis workflows and flexible tools for measuring and manipulating nuclear medicine data.

Clinical Evidence

No clinical testing was performed. Evidence consists of bench-only software validation, including functional design validation and usability validation, confirming that all user needs and system requirements were met.

Technological Characteristics

Standalone software operating on Windows 10/Server 2019. DICOM 3.0 compatible. Implements 3D iterative OSEM reconstruction, filtering, and registration algorithms. Complies with IEC 62304 (software lifecycle), IEC 62366-1 (usability), and ISO 12052/NEMA PS3 (DICOM).

Indications for Use

Indicated for reviewing medical images including planar scans (Static, Whole Body, Dynamic, Multi-Gated) and tomographic scans (SPECT, Gated SPECT) acquired by gamma cameras. Intended for use by trained medical professionals (clinicians, technicians) in hospitals or imaging centers. No specific target population. Not indicated for mammography or dental diagnostics.
