Synapse 3D, Synapse 3D Base Tools v6.1

Synapse 3D Base Tools v6.1 is advanced medical imaging software intended to provide trained professionals with comprehensive tools for interpreting diverse DICOM medical images, aiding in diagnosis and treatment planning through enhanced visualization, image processing, and analysis. The system utilizes a Windows-based platform and incorporates various algorithms, including deep learning for segmentation and specialized functions for CT and MR image analysis, to improve clinical decision-making and workflow efficiency.

Synapse 3D Base Tools v6.1 is medical imaging software designed for trained medical professionals to aid in the reading, interpretation, reporting, and treatment planning processes. It accepts and processes DICOM compliant medical images from a variety of imaging modalities, including CT, MR, CR, US, NM, PT, and XA, among others, although it is not intended for the primary diagnostic interpretation of mammography images. The software operates on Windows server/client configurations, can be integrated with Fujifilm’s Synapse PACS, and serves as a basic software module that works with other cleared clinical applications in the Synapse 3D product family. Its core functionalities encompass a broad range of tools such as 2D viewing, volume rendering, 3D and 4D volume viewing, orthogonal, oblique, and curved Multi-Planar Reconstructions (MPR), Maximum/Average/Minimum Intensity Projections (MIP/RaySum/MinIP), image fusion, image subtraction, surface rendering, time-density distribution analysis, basic image processing, CINE, measurements, annotations, reporting, printing, storing, distribution, and general image management tools. Version 6.1 of Synapse 3D Base Tools introduces updated and new features, notably in advanced image analysis. These include tools for regional segmentation of anatomical structures, path definition through vascular and tubular structures, and boundary detection, with some segmentation applications implemented using deep learning methods like 'Fully Convolutional Networks' alongside existing algorithms such as 'graph cuts'. New modality-specific imaging tools have been added, including virtual endoscopic viewing for CT images, and for MR images, capabilities for ADC image viewing, delayed enhancement image viewing, and diffusion-weighted MRI data analysis. The software underwent extensive nonclinical testing, including verification and validation of system functionality, component performance, integration, usability, and risk mitigation. Benchmark performance testing using actual clinical images was conducted to demonstrate that the semi-automatic or automatic segmentation, detection, and registration functions achieved expected accuracy performance.
