PTM3D and gPTM3D

PTM3D is dedicated to interactive retrivial, exploration, and measurement of 3D medical datasets. The system currently runs on standard PC computers and it is used on line in radiology centers. Clinical applications of PTM3D received many awards, including the prestigious "purple ribbon" at RSNA 2004.

PTM3D transfers, archives and visualizes DICOM encoded data

Besides moving independently along the usual three axes, the user is able to view the cross-section of the DICOM image along an arbitrary plane and to move it. demo

PTM3D provides computer-aided generation of three-dimensional representations from TDM, MRI, PET-scan, or echography 3D data. A reconstructed volume (organ, tumor) is displayed inside the 3D view. The reconstruction also provides the volume measurement, required for therapeutic decisions.

PTM3D volume reconstruction is for instance the basis of an augmented reality system for percutaneous nephrolithotomy.

gPTM3D has been demonstrated in various events, including the 3rd EGEE conference, and was selected for the first EU review.

Using the interaction architecture developped in the project, the volume reconstruction module has been coupled with the EGEE grid with the following results

• the overall response time is compatible with user requirements (less than 2 minutes)
• the local interaction scheme (stop, restart, modify) remains unmodified.

A typical grid-added value is surgical planning for percutaneous nephtolithotomy. The planning is a complex process, where the volume reconstruction part is not the most time-consuming, but nevertheless in the order of tens of minutes for sequential (PC-based) execution. Interactive real-time response time for will allow for more accurate measurements, and has thus the potential to improve health care.
