Multi-axis specimen imaging device with embedded orientation markers
A specimen holding and positioning apparatus operable to substantially non-movably maintain a specimen (e.g., an excised tissue specimen) in a fixed or stable orientation with respect to the apparatus during imaging operations (e.g., x-ray imaging), transport (e.g., from a surgery room to a pathologist's laboratory), and the like for use in facilitating accurate detection and diagnosis of cancers and/or other abnormalities of the specimen.

providing a tissue specimen retaining apparatus having a body that includes a retention surface, a first orientation marker, a second orientation marker, and at least one indicator;
positioning the tissue specimen on the retention surface and relative to the at least one indicator such that the position of the tissue specimen on the retention surface corresponds to an excision location of the tissue specimen on a patient's breast, wherein the at least one indicator conveys a location of the first orientation marker;
generating a first image of the tissue specimen at an imaging system, wherein the tissue specimen retaining apparatus is orientated such that the retention surface is orthogonal to an imaging axis of the imaging system, wherein the first orientation marker, the second orientation marker, and the at least one indicator appear in the first image, and wherein the first orientation marker is spaced from the tissue specimen in the first image and indicates either a left breast or a right breast excision location and the second orientation marker is fully encompassed within the tissue specimen in the first image;
generating a second image of the tissue specimen at the imaging system, wherein the tissue specimen retaining apparatus is oriented such that the retention surface is not orthogonal to the imaging axis of the imaging system, wherein at least the first orientation marker and the second orientation marker appear in the second image, and wherein the first orientation marker is spaced from the tissue specimen in the second image and indicates either the left breast or the right breast excision location and the second orientation marker is also spaced from the tissue specimen in the second image and indicates an approximate location of a front or a nipple of the breast; and
determining, based on the position of the tissue specimen relative to the first orientation marker and the second orientation marker, the excision location of the tissue specimen on the patient's breast in the first image and the second image such that at least one of the first and second images are oriented relative to a corresponding original mammogram image.
2. The method of claim 1 , wherein the at least one indicator includes a graphic or a design.
3. A method of imaging a tissue specimen, the method comprising:
providing a tissue specimen retaining apparatus having a body that includes a retention surface and at least a first orientation marker and a second orientation marker;
positioning the tissue specimen on the retention surface and relative to at least one of the first and second orientation markers such that the position of the tissue specimen on the retention surface corresponds to an excision location of the tissue specimen on a patient's breast;
generating a first image of the tissue specimen at an imaging system, wherein the tissue specimen retaining apparatus is orientated such that the retention surface is orthogonal to an imaging axis of the imaging system, wherein the first orientation marker and the second orientation marker appear in the first image, and wherein the first orientation marker is spaced from the tissue specimen in the first image and indicates either a left breast or a right breast excision location and the second orientation marker is fully encompassed within the tissue specimen in the first image;
generating a second image of the tissue specimen at the imaging system, wherein the tissue specimen retaining apparatus is oriented such that the retention surface is not orthogonal to the imaging axis of the imaging system, wherein the first orientation marker and the second orientation marker appear in the second image, and wherein the first orientation marker is spaced from the tissue specimen in the second image and indicates either the left breast or the right breast excision location and the second orientation marker is also spaced from the tissue specimen in the second image and indicates an approximate location of a front or a nipple of the breast;
determining, based on the position of the tissue specimen relative to the first and second orientation markers, the excision location of the tissue specimen on the patient's breast in the first image and the second image; and
orienting the first image and the second image relative to at least one corresponding image of the patient's breast containing the tissue specimen prior to excision.
4. The method of claim 3 , further comprising overlaying the first image on the at least one corresponding image of the patient's breast.
5. The method of claim 3 , wherein the body of the tissue specimen retaining apparatus includes a first retention member having the first orientation marker and a second retention member having the second orientation marker, the method further comprising securing the tissue specimen at least partially between the first retention member and the second retention member.
6. The method of claim 3 , wherein the body of the tissue specimen retaining apparatus has at least one indicator readable in the first image, wherein the determination of the excision location of the tissue specimen on the patient's breast in the first image is also based on the at least one indicator.
7. The method of claim 6 , wherein the at least one indicator includes a graphic or a design.
8. A method of imaging a tissue specimen, the method comprising:
providing a tissue specimen retaining apparatus having a body that includes a retention surface, a first orientation marker, and a second orientation marker;
positioning the tissue specimen on the retention surface and relative to the first and second orientation markers;
generating a first image of the tissue specimen at an imaging system, wherein the tissue specimen retaining apparatus is orientated such that the retention surface is orthogonal to an imaging axis of the imaging system, wherein at least the first orientation marker and the second orientation marker appear in the first image, and wherein the first orientation marker is spaced from the tissue specimen in the first image and indicates either a left breast or a right breast excision location and the second orientation marker is fully encompassed within the tissue specimen in the first image;
generating a second image of the tissue specimen at the imaging system, wherein the tissue specimen retaining apparatus is orientated such that the retention surface is not orthogonal to the imaging axis of the imaging system, wherein the first orientation marker and the second orientation marker appear in the second image, and wherein the first orientation marker is spaced from the tissue specimen in the second image and indicates either the left breast or the right breast excision location and the second orientation marker is also spaced from the tissue specimen in the second image and indicates an approximate location of a front or a nipple of the breast;
generating a third image of the tissue specimen at the imaging system, wherein the tissue specimen retaining apparatus is orientated at a different orientation than the first image and the second image, wherein the first orientation marker and the second orientation marker appear in the third image, and wherein the second orientation marker is spaced from the tissue specimen in the third image and indicates the approximate location of the front or the nipple of the breast;
determining an excision location of the tissue specimen on a patient's breast based on the relative position of the first and second orientation markers relative to the tissue specimen in the first, second, and third images; and
orienting at least one of the first image, the second image, and the third image relative to at least one corresponding image of the patient's breast containing the tissue specimen prior to excision.
9. The method of claim 8 , further comprising overlaying at least one of the first image, the second image, and the third image on the at least one corresponding image of the patient's breast.
