MedNuc Plugin collections

 

A few intro notes....

The following plugins were developed by a group of researchers at the Department of Physiopathology, University at Florence, and the Department of Computer Science, University at Genoa, Italy.

Most of them were designed for PET/SPECT tomographic images, acquired both by whole body and brain scanners; however they can easily be applied to other kind of (medical) images as well.

The interested reader can find a full description of the underlying project, as well as motivations, goals and purposes, in the references listed below.

This work is still in progress and more plugins might be coming soon.

 

The plugins

MIP computes a sequence of lateral projections of a volume - usually consisting of transaxial planes - according to the Maximum Intensity Projection (MIP) method. Each lateral component can be weight corrected according to its distance from the front plane. A variant of the alghorithm allows to compute the Total Intensity Projections. The resulting images are inserted into a new stack to which a pseudo color map is applied, and that can be regularly displayed from within ImageJ.

OrtView offers an alternative way to display an image stack: given a volume and the coordinates of a point within that volume, the three orthogonal planes passing through that very point are shown, both separately or combined together. The user can interact with the image window by changing the focus location and applying some processing to the volume such as axial smoothing, interpolation, rotation, and contrast correction.

GePetOp loads a DICOM study acquired by a PET GE. A study consist of a collection of .dcm files, one for each transaxial slice, with all files related to the same data being located in a common directory and having a name that fulfills specific simple rules.
The plugin is deprecated. See GePetReorder for a more efficient version.

GePetReorder has been designed as a replacement of GePetOp, to deal also with whole body PET data. It opens a 3D Dicom study loading the slices in the correct order as according to the Dicom header. Hereafter the whole volume can be normalized in a single step using the maximum of the entire stack for the normalization factor (rather than normalizing each single slice, thus leading to images which are not axially smooth).

GeCardPetOp is similar to GePetOp. It loads a tomographic, sequential, usually cardiological, DICOM studies acquired by a General Electric PET device. In order to be loaded into ImageJ, such datasets need a renaming of all filenames they consist of, according to either a spatial or a temporal order, as chosen by the user.

CardProfile computes and displays the maximum values along the rays passing through a point of a (usually cardiological) volume selected by the user. On the basis of the results it computes and plots some statistical values.

RenalConv reads and displays a sequential, renal study acquired by a Picker Gamma Camera, and saves it into the proprietary format of the Cure imaging package used for a quantitative processing of renal scintigraphies at the Niguarda Hospital at Milan.

StackExtend linearly interpolates the slices of a stack, thus doubling the size (i.e. the number of slices) of the stack itself.
