PUKKA-J TEAMS UP WITH IMAGE FUSION COMPANY TO MARKET UNIQUE PACKAGE QUANTIVATM FOR PET/CT

Pukka-j recently concluded an agreement to distribute QuantivaTM software in the UK and Europe. This unique package provides the user with the ability to co-register CT and PET patient data using both rigid and non-rigid body transformations and to display the resulting fused PET/CT images.

Often a Trust or region will acquire just one PET/CT scanner, sited at a major hospital, and this facility will have multiple referring hospitals, cancer clinics and therapy planning facilities sharing the same resource. At the sites, there is often a mixture of equipment available to accept and review the PET/CT data. Some sites have no PET/CT workstations, and some do, but the workstation may be from a different manufacturer and will not be interoperable with the PET/CT scanner data. This need for new image display and navigation software often exceeds the capacity of commercial software manufacturers to rapidly adapt and provide new tools that are needed by clinical and academic communities. Typically, the tools required to manipulate rapidly the large sets of 3-D and 4-D data are hard to find and are only available on very high-end expensive workstations. In addition, they usually lack some specialised sets of tools that are specific for a certain number of applications and diagnostic or therapeutic tasks.

While hybrid PET/CT scanners provide rigid-body fusion capabilities, non-rigid fusion is required to correct for respiration and different body position artefacts. QuantivaTM extends the protocols available beyond shallow-breathing PET and shallow-inspiration breath-hold CT. Full-inspiration breath-hold CT fusion with PET capability enhances lung tumour diagnosis. CT arms-up and arbitrary PET arm-position co-registration capability eliminates CT streaking artefacts and enhances patient comfort. The QuantivaTM PET/CT image fusion software performs rapid "one-click" non-rigid PET/CT image fusion both automatically and rapidly.

Two images, CT-only and user-adjustable PET/CT fusion mixture, are displayed in each 2D axial, sagittal and coronal fusion viewer. Linked cross-hairs display the same position in both for easy comparison and one click on a point-of-interest in the 3D MIP triangulates the same point the 2D views. The non-rigid coregistration may also be applied instead to the cross-hairs which then map to the corresponding point in the original PET and CT images. In addition, double-clicking on a point of interest, a "hot spot", in the 3D MIP image, or in any of the 2D views will automatically create a 3D volume of interest (VOI) with an enclosing isosurface of constant SUV.

Kevin Wilson, Managing Director of Pukka-j commented,

With the growth in the PET/CT sales we anticipate QuantivaTM to be the right product at the right time for the market.
Quantiva for PET CT
Diagnosis of a patient presenting with widespread metastatic tumours. The PET (arms-down with normal respiration) and CT arms-up with full inspiration breath-hold) images were acquired separately on independent scanners and were imported into the QuantivaTM workstation where non-rigid PET/CT image coregistration and fusion were automatically performed. Note the correct matching between the active and necrotic regions of the large metastatic liver tumour.
