Pixies
Apteryx S.A.R.L., started the Pixies software in 1998 in collaboration with Unit 494 INSERM (French National Institute of Health) and supported by the French Department of Education, Research and Technology (Ministère de l'Education Nationale, de la Recherche et de la Technologie). Recent advances in medical imaging now often yield multidimensional images, such as time series in functional Magnetic Resonance Imaging (fMRI), in dynamic computed tomography (CT), in nuclear medicine (Single Photon Emission Computed Tomography - SPECT - or Positron Emission Tomography - PET) or in contrast Ultrasound. However, the image series resulting from the sophisticated new imaging devices often include hundreds of images. How can we interpret so much data in the most efficient way? So far, the images are usually just interpreted visually, by playing a dynamic series as a movie for instance, to better grab the functional information described by the time series. Such visual analysis is obviously tedious, time-consuming, and non-reproductible. Pixies helps radiologists, physicians and researchers, to deal the most efficiently with large image series, by providing a unique processing method that summarizes the information underlying an image series into a limited number of factor images and associated time curves. Pixies also features tools for exploring image sequences, operators for compensating for patient motion (image registration), and more conventional image processing operators.
The JAI pull model lies at the center of Pixies architecture. The user can build whole processing chains using the numerous JAI standard operators and Pixies-specific operators. JAI remote processing features allow Pixies to be split between a computation server and a lightweight visualization client, and its pluggable architecture is used by users to add their own processing operators to Pixies. Apteryx also provides the DICOM Image I/O plugin for reading, writing, and exchanging medical images using the DICOM standard. This plugin uses the JAI Image I/O tools when they are installed on the system to support a wider range of compression algorithms and benefit from native acceleration.
