Abstract
An external stylus provides an impulse to correct mal-alignments of the Atlas (C1). The placement and direction of the impulse is guided by the analysis of a plurality precisely placed or acquired tomographic images, preferably MRI images.
Claims20
A method of patient treatment comprising the steps of:
- a) obtaining a first plurality of cine MRI images that includes at least a portion of C1-C7,
- b) analyzing the MRI images to determine a potential correlation of misalignment or placement of at least one of C1-C7 with an abnormality in the cine MRI images,
- c) externally adjusting C1 using a corrective impulse to correct the misalignment or placement of at least one of C1-C7,
- d) obtaining a second plurality of cine MRI images that includes at least a portion of C1-C7,
- e) determining if the step of external adjustment has corrected the abnormality detected in step b).

A method of patient treatment comprising the steps of:
- a) obtaining a first plurality of cine phase contrast MRI images to dynamically image a flow of at least one of cerebral spinal fluid (CSF) and blood,
- b) analyzing the cine phase contrast MRI to determine a potential correlation of misalignment or placement of at least one of C1-C7 with a coincident regions of abnormal flow of at least one of cerebral spinal fluid (CSF) and blood,
- c) externally adjusting C1 using a corrective impulse using at least one MRI image to determine the direction of the corrective impulse,
- d) obtaining a second plurality of cine phase contrast MRI images to dynamically image a flow of at least one of cerebral spinal fluid (CSF) and blood,
- e) determining if the step of external adjustment has corrected the abnormal flow of at least one of cerebral spinal fluid (CSF) and blood identified in step b).

A method of patient treatment comprising the steps of:
- a) obtaining a first plurality of cine MRI images to dynamically image the movement of the cervical spine of the patient as the head is moved from a least one of extension and flexion to neutral position while the patient is in an upright posture,
- b) analyzing the cine MRI to determine a potential correlation of misalignment or placement of at least one of C1-C7 and/or connective ligaments during the movement of at least one of extension and flexion,
- c) externally adjusting C1 using a corrective impulse using at least one MRI image to determine the direction of the corrective impulse,
- d) obtaining a second plurality of cine MRI images to dynamically image the movement of the cervical spine of the patient as the head is moved from a least one of extension and flexion to neutral position while the patient is in an upright posture,
- e) determining if the step of external adjustment has corrected the observed misalignment or placement of at least one of C1-C7 and/or connective ligaments observed in the first plurality of cine MRI images.
