Abstract
An apparatus and method for aligning and imaging a body part which immobilizes the body part within a stereotactic body localization system having an imaging resolver fiducial localizer for precise imaging and localization of the body parts within the apparatus. Both anterior and posterior immobilization methods can be used. A continuous array of coupled fiducials is employed with at least one pair formed in a π/2 horizontal linked sine and cosine wave fiducial pattern.
Claims21
A whole body stereotactic localization and immobilization system comprising:
- a patient elongated support frame having a longitudinal axis including at least two fiducials, two of said at least two fiducials positioned generally parallel with the longitudinal axis, said two fiducials each comprising a repetitive trigonometric waveform, the position of the first one of said two fiducials being longitudinally offset from the position of the second one of said two fiducials;
- and
- a body immobilizing device for maintaining the patient's body in fixed relationship to the fiducials at least during imaging, of said two fiducials having trigonometric waveforms, one of said waveforms is sinusoidal and the second is cosinusoidal.
A whole body stereotactic localization and immobilization system comprising:
- a patient elongated support frame including an imaging resolver having at least two fiducials each of which has a repetitive trigonometric waveform, one of said repetitive waveform fiducials offset from a second repetitive waveform fiducial, of said two fiducials having trigonometric waveforms, one of said waveforms is sinusoidal and the second is cosinusoidal;
- and
- means for temporarily immobilizing the patient's body in relation to the imaging resolver.
A method for stereotactic localization of a portion of a human body comprising:
- placing the patient's human body including a lesion on a support frame;
- temporarily immobilizing the patient's body during imaging by a scanning device such as computed tomography or magnetic resonance imaging;
- providing a fiducial pattern on said frame for creating markers on the patient image to create a reference system;
- configuring the fiducial pattern so as to include at least two fiducials each of said fiducials having a repetitive trigonometric waveform one of said repetitive waveform fiducials offset from a second repetitive waveform fiducials, of said two fiducials having trigonometric waveforms, one of said waveforms is sinusoidal and the second is cosinusoidal;
- providing a computer system for displaying said images, including said markers, and a software program for utilizing said fiducial markers for accurate stereotactic positioning information;
- creating a radiation therapy plan for treatment of a lesion the position of which is determined based on the images and computer program;
- immobilizing the patient's body in a radiation therapy delivery device;
- and
- delivering radiation therapy to the applicable portion of the patient's body so as to treat the lesion.
