  • Patent number: 8082023
    Abstract: A method and apparatus for marking a lesion in a body part is provided. The method includes the steps of obtaining a first nuclear-emission image of the body part; determining a position of the lesion from the first image; percutaneously introducing a cannula to the determined position; inserting a wire into the cannula, the wire including radioactive material; retracting the cannula while holding the wire in place; and obtaining a second nuclear-emission image of the body part. The second image includes data relating to a position of the lesion and data relating to a position of the wire.

  • Publication number: 20100280364
    Abstract: An apparatus and a computational method are provided for localizing a positron-emitting source during an intervention using positron emission tomography (PET) imaging. The apparatus is designed to accelerate the image acquisition and reconstruction process such that the resulting image presentation can be used to quickly reposition an interventional device in relation to a lesion. By limiting the processing of data in the acquisition to a focal plane which extends through the localization target, and which is oriented to capture and display motion during the intervention, and then by displaying a persistence image which is frequently refreshed, a user can visualize movement of the positron-emitting source for optimizing the position of the interventional device. The positron-emitting source(s) can be radiolabeled tissue, a radiolabeled interventional device, a radiolabeled fiducial, or any combination thereof.
