The HeartView system is an internet-based application intended for use by nuclear medicine or radiology practitioners and referring physicians for the automated processing, review, quantification, and multidimensional review of nuclear medicine cardiology medical images, and specifically, radionuclides distributed in the body using planar and tomographic short axis images. HeartView may be used in various clinical settings including a hospital, clinic, imaging center, physician office, or remote locations. The HeartView system implements algorithms for automatic quantification of myocardial perfusion single photon emission computerized tomography (SPECT) as well as quantification of ejection fraction, wall motion, and thickening from gated myocardial perfusion SPECT images. Gated results are presented as 3D plots that can be used to depict, localize, and/or quantify the distribution of radionuclide tracers and anatomical structures in scanned body tissue for clinical diagnostic purposes, including quantitative assessments of cardiac function (e.g., systolic and diastolic function, regional wall thickening, wall motion, transient ischemic dilation, and phase analysis).

The HeartView platform is a comprehensive internet-based application designed to process, review, and automatically perform quantitative analysis of cardiac nuclear medicine procedures. HeartView implements algorithms for automatic quantification of myocardial perfusion SPECT, as well as quantification of ejection fraction, wall motion, and thickening from gated myocardial perfusion SPECT. The algorithm takes short axis slices reconstructed from raw datasets of gated and averaged acquisitions in rest and stress, and operates in multi-dimension (3D), rather than processing individual slices separately. For gated datasets, it processes the dataset as a whole rather than processing each frame separately, which adds additional knowledge to the algorithm for its computations, and allows enforcement of the constraint that the mid-myocardium volume is constant during the whole heart beat cycle.

The VidiStar PACS & DICOM Viewer Software system is a picture archiving and communications system (PACS) intended to be used as a networked Digital Imaging and Communications in Medicine (DICOM) and non-DICOM information and data management system. The VidiStar PACS & DICOM Viewer Software is comprised of modular software programs that run on standard "off-the-shelf" personal computers, business computers, and servers running standard operating systems. VidiStar PACS & DICOM Viewer Software system is an image, data storage and display software that accepts DICOM data from laboratories, which support DICOM standard imaging data and structured reporting transfer(s). The system provides the capability to: organize images generated by OEM vendor equipment, perform digital manipulation, create graphical representations of anatomical areas, perform quantitative measurements, and create DICOM structure reports, all over the Internet. All quantitative data ranges are derived from the clinical experience of laboratories and are included in observation libraries for VidiStar users. VidiStar strongly recommends that users review these ranges with their individual diagnostic needs in mind prior to using the VidiStar PACS & DICOM Viewer Software system for clinical reporting. The VidiStar PACS & DICOM Viewer Software system should not be used for reviewing full-field digital mammograms.

The VidiStar PACS & DICOM Viewer Software System is a picture archiving and communications system software used to process, display, transfer, enable reports, communicate, store and archive digital medical images using Transmission Control Protocol/Internet Protocol (TCP/IP). It supports DICOM structured reports for creating, rendering, storage and archiving.
