Imaging fixation and localization system with respiratory feedback device
First Claim
1. A stereotaxic localization system for use in conjunction with an imaging system, comprising:
- a. A respiratory feedback device in which respiratory volume is directly measured to define a phase of respiration of a patient, said phase of respiration providing an indication of the position of internal organs of the patient, said respiratory feedback device comprising;
i. A chamber, said chamber comprising a respiration port for respirative connection with the patient;
ii. A volume sensor means in communicative connection with said chamber; and
iii. A display means for displaying respiratory volume to the patient, said display means being in operative connection with said volume sensor means, whereby respiratory volume at a particular time is displayed to the patient to allow the patient to actively control respiratory volume and thereby the position of the patients internal organs; and
b. A stereotaxic localization means for placing a probe at a desired location within a body during a known phase of respiration as determined by said respiratory feedback device.

Abstract
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.
