The main panel is the essential tool for viewing and analyzing heterogeneous medical images
(CT, MRI, T0F, DWI) resulting from diagnostic tests and from subsequent processing of the same images.
In fact, the panel allows, thanks to a special function menu, to load the DICOM series relating to
the images, to view them according to the three axial, sagittal and coronal projections, and simultaneously
view the 3D reconstruction of the same loaded images.
By interacting with the interface, it is possible to scroll the volume in the three directions, to change the
display parameters of the 2D images and the 3D model: zoom, point of view, transparency levels.
From the same panel you can access all the features that the software offers for the analysis and processing of medical images.
The images displayed and processed by the TeleMed software are highly informative, as they integrate details detected by heterogeneous imaging (CT, MRI, DWI, TOF) merging them into a single complete and integrated model, useful for both diagnostic and pre-surgical planning purposes. This is possible first of all thanks to the functions related to the import / export of images: the software therefore allows not only to load and display heterogeneous images within it (DICOM Series, STL files, VTK files), but also to write new images relating to the images resulting from image-processing activities (registration, segmentation, tractography).
DICOM Header Reader
DICOM image file constitute the “header.” It stores demographic information about the patient, acquisition parameters for the imaging study, image dimensions, matrix size, color space, and a host of additional nonintensity information required by the computer to correctly display the image. The information within the header is organized as a constant and standardized series of tags. Analyzing the DICOM header may also give valuable information regarding the imaging study itself: such demographic information of the patient and a host of other information about the imaging study is encoded within an image header. TeleMed software allows to analyze the header of each loaded DICOM series. In the interest of patient confidentiality, all information identifying the patient are removed from the DICOM header when a DICOM file is uploaded for such purposes. A simple and easy method of ensuring this “anonymization” whereby all patient information is removed from the DICOM header. This is achieved in XML file user use only.
The measure tool allows the user to interactively trace measurement indicators, both on the images displayed on the main panel
and directly on the 3D model, at points and / or anatomical structures of interest.
Furthermore, the measurements plotted on the 2D slices can also be automatically reported on the 3D model, in the corresponding positions.
Registration is a technique aimed to align two objects using a particular transformation. A typical example of registration is to have two medical images from the same patient taken at different dates. It is very likely that the patient assume a different position during each acquisition. A registration procedure would allow to take both images and find a spatial transformation to find the corresponding pixel from one image into the other. Another typical example of registration is to have a geometrical model of an organ, let's say a bone. This model can be used to find the corresponding structure in a medical image. In this case, a spatial transformation is needed to find the correct location of the structure in the image. This functionality allows the fusion of heterogeneous medical images and, therefore, the generation of a complete anatomical model, integrated and rich in details obtained from multimodal imaging.
Segmentation is a process of partitioning an image into meaningful regions. It is used to obtain a more compact representation, to extract objects
or as a tool for image analysis.
