Segmenting the left ventricle

Segmentation of the left ventricle (LV) is achieved after applying the “Red cluster” option within the blood pool. The cluster threshold level is initially automatically set to the best possible value and subsequently optimized by manual adjustment.


The segmentation results accurate and time efficient.


End-diastolic and end-systolic frames are displayed in real time for the user to easily identify the bigger and smaller volume. Ejection fraction (EF), end-diastolic (EDV), end-systolic (ESV), stroke volume (SV), cardiac output (CO).


All the volume and area values computed for each slice and frame can easily be exported for further data analysis.


In the same way, the segmentation can be applied to the right ventricle (RV).

Segmenting ischemia


Segmenting ischemia


Ischemic areas are segmented out from similar tissues using Clinical Volumes options.


In the heart example reported, the “Blue cluster” option is utilized to segment the ischemic area while the “Orange cluster” option to segment the valuable myocardium.


In the brain example, an “Orange cluster” is used to differentiate brain ischemic areas.


When segmenting ischemia areas, the user can customize segmentation by the use of the several options available. This represents one of the added value of the Clinical Volumes software.


Similar segmentations can be applied to all those image areas which, although not ischemic, present signal intensities dissimilar from neighborhood tissues.

Segmenting the brain

Segmenting brain areas can represent a tedious task. Clinical Volumes can help in making the segmentation process easyer and quicker. Utilizing the several features that the software offers, the analysis time is usually reduced maintaining excellent accuracy.


Gray and white matter can be segmented by a click of the mouse.

Segmenting tumors

Tumors, such that those in brain, can be segmented utilizing Clinical Volumes options. The “Red cluster” or the “Orange cluster” can be used for such image analysis.


Tumor total volumes and single slice areas are easily accessible from the data file.

Segmenting adipose tissues

 Segmenting adipose tissues

Adipose tissues usually present higher signal intensity than surrounding tissues making them a good target for the Clinical Volumes segmentation.


Using the “Orange cluster” option and propagating it through the entire data set, adipose tissues are therefore identified and the total volume obtained. In order to estimate its mass in mg, the total volume can be multiplied by a density factor.

 Segmenting vessel walls

Vessel wall segmentation is easily achieved by the Clinical Volumes software in transversal sections of the aortic arch. The signal intensity of the wall is boosted by the accumulation of a gadolinium contrast agent used to characterize the latter from the remaining tissues.


This kind of segmentation can be performed anywhere in the body whenever experiencing similar enhancing effects. A typical example is that of arteriosclerosis disease where plaques can be enhanced and distinguished from the remaining vessel.
