Skin reference grid, especially useful in needle-biopsy and/or TC-guided acupuncture exams, and/or for nuclear magnetic resonance exams

摘要

When used for needle-biopsy and/or TC-guided acupuncture exams, the grill comprises longitudinal C and transverse 3-3' radio-opaque elements that are spread out on the body of the patient, in the zone corresponding to the internal pathology L being biopsied and/or treated. Said radio-opaque elements of the grill appear on the frontal and axial scans of the TC as luminous or opaque references, spaced out in familiar manner. Once the radio- opaque references of interest are identified to reach the pathology in nontraumatic fashion, a collimation point P is made on the skin of the patient, at the ideal intersection of said references, from which the biopsy and/or therapy needle will be introduced, with the inclination and the depth as determined from the preceding combined use of the same grill used with the TC scans. The grill, made of nonmagnetic and radio frequency- passive materials, can also be used in NMR exams for the targeted study of internal pathologies. IMAGE
