Hepatica (Hepatica v1) is a post-processing medical device software that presents quantified metrics which may contribute to the assessment of a patient’s liver health.Hepatica (Hepatica v1) uses image visualisation and analysis tools to process DICOM 3.0 compliant magnetic resonance image datasets to produce semi-automatic segmented 3D models of the liver based on the work of Couinaud and the Brisbane 2000 terminology. For each identified Couinaud segment, volumetric data is determined and reported. Hepatica (Hepatica v1) may also report iron corrected-T1 (cT1) and PDFF calculated using the IDEAL methodfrom multi-slice acquisitions, on a per segment basis, over the whole liver. Both metrics present numerical values of different fundamental liver tissue characteristics that can be used as measures of liver tissue health.Hepatica (Hepatica v1) provides trained clinicians with additional information to evaluate the volume and health of a patient’s liver on a segmental basis. It is not intended to replace the established procedures for the assessment of a patient’s liver health. However, information gathered through existing diagnostic tests, clinical evaluation of the patient, as well Hepatica(Hepatica v1), may support surgical decision making.

CoverScan is a medical image management and processing software package that allows the display, analysis and post-processing of DICOM compliant medical images and MR data.CoverScan provides both viewing and analysis capabilities to ascertain quantified metrics of multiple organs such as the heart, lungs, liver, spleen, pancreas and kidney.CoverScan provides measurements in different organs to be used for the assessment of longitudinal and transversal relaxation time and rate (T1, SR-T1, cT1, T2), fat content (proton density fat fraction or PDFF) and metrics of organ function (e.g., left ventricular ejection fraction and lung fractional area change on deep inspiration).These metrics derived from the images, when interpreted by a licensed physician, yield information that may assist in diagnosis, clinical management and monitoring of patients.CoverScan is not intended for asymptomatic screening. This device is intended for use with Siemens 1.5T MRI scanners.

SyMRI is a post-processing software medical device intended for use in visualization of the brain. SyMRI analyzes input data from MR imaging systems. SyMRI utilizes data from a multi-delay, multi-echo acquisition (MDME) to generate parametric maps of R1, R2 relaxation rates, and proton density (PD). SyMRI can generate multiple image contrasts from the parametric maps. SyMRI enables post-acquisition image contrast adjustment. SyMRI is indicated for head imaging.SyMRI is also intended for automatic labeling, visualization and volumetric quantification of segmentable brain tissues from a set of MR images. Brain tissue volumes are determined based on modeling of parametric maps from MDME images. When interpreted by a trained physician, SyMRI images can provide information useful in determining diagnosis. SyMRI should always be used in combination with at least one other, conventional MR acquisition (e.g. T2-FLAIR).
