Imaging fixation and localization system with respiratory feedback device

Image Number 7 for United States Patent #5464410.

The present invention relates to a method and apparatus for lesion localization and stereotactic placement of probes into the body utilizing an imaging system. Localization of the probe with reference to the device itself is accomplished by providing a base which includes a base localization grid and at least one localizing side member which includes a side localization grid. Extremely accurate placement of the probe within the body is accomplished by providing a spanning member to which a probe holder is attached. The spanning member is designed so as to be attachable to the base at any angle in the sagittal plane with respect to the base. The stereotactic device also includes a precompression device to compress soft tissue in the area of the probe entry point before penetration. A respiration feedback device which directly measures respiratory volume is also provided to enable a patient to control the patient's degree of respiration. The feedback device can thus ensure that each scan is taken in the same phase of respiration.
