Abstract
Abstract A self contained set of imaging apparatus which permit an excised tissue to be handled, inked, imaged in radiology and transported to pathology untouched by human hands. Absolute margins of tissue are inked by solution injected into sealed, disposable bag from syringe attached to the bag. Inked tissue is removed from bag and placed upon fluid-absorbent blotter inscribed with radiographically opaque grid, inside of transparent container. Hinged top and bottom panels of liquid-tight container secure tissue in place. Tissue is visible from outside of container during transport, x-ray imaging, and subsequent pathologic evaluation. Further, the image presented to the pathologist with the inked tissue permits extremely accurate identification of locations of suspect element. The pathologist can easily view the enclosed, undisturbed sample and associated radiograph prior to dissection which can be done within said apparatus if so desired.
