Abstract

Tissue mapping and imaging systems are disclosed along with methods for mapping tissue. The systems can include an image recording and mapping system in communication with a manual image scanning device having an imaging probe. The manual image scanning device can be configured to scan a volume of tissue and output at least one scanned image and to electronically receive and record the at least one scanned image. The image recording and mapping system can be further configured to construct an idealized tissue map from the at least one scanned image. The image recording and mapping system can also include a position tracking system configured to detect and track the position of the imaging probe and provide location identifier information for the at least one scanned image. The idealized tissue map can be an idealized depiction of an anatomy. The idealized tissue map can include references points.

Claims

1. A tissue mapping system for constructing an idealized representation of a patient'"'"'s scanned breast comprising:

a recording system comprising a controller in communication with an imaging probe, the controller configured to electronically receive and record the scanned images from the imaging probe, to correlate recorded position of a region of interest to an idealized position of the region of interest on an idealized depiction of the anatomy and a position tracking system comprising at least one position and orientation sensor configured to provide data corresponding to the position and three-dimensional orientation of the imaging probe by generating position data for the scanned image from a plurality of position sensors providing data about positions of the imaging probe;

electronically communicating the position data from the plurality of position sensors to a tissue map processor, wherein based on the position data the processor identifies a coronal plane for the patient, a first anterior-posterior projection through a tissue reference point to the coronal plane, and a second anterior-posterior projection through a probe reference point to the coronal plane;

computing a relative angle between the first and second projections and medial-lateral vector through the tissue reference point;

computing a distance between the first and second projections;

constructing an idealized breast map based on the relative angle and distance computed;

conforming the geometry of the recorded image to the idealized breast map; and

depicting a recorded tissue feature in the idealized breast map by translating the recorded position of the tissue feature in the scanned image to a corresponding position in the idealized breast map.

2. The system of claim 1, wherein the controller is configured to determine a differential angle of a patient'"'"'s coronal plane with reference to a plane of the floor.

3. The system of claim 1, wherein the controller is configured to append location identifier information to the scanned images from the imaging probe.

4. The system in claim 1, wherein the image recording and mapping system is configured to scale a medial-lateral location of a region of interest to fit the idealized depiction based on information from the position tracking system.

5. The system in claim 1, wherein the controller is configured to scale a superior-inferior location of a region of interest to fit the idealized depiction based on information from the position tracking system during the lateral and medial scans.

6. A method of constructing an idealized representation of a patient'"'"'s scanned breast comprising:

recording a scanned image of the patient'"'"'s breast obtained by an imaging probe;

generating position data for the scanned image from a plurality of position sensors providing data about positions of the imaging probe;

electronically communicating the position data from the plurality of position sensors to a tissue map processor, wherein based on the position data the processor identifies a coronal plane for the patient, a first anterior-posterior projection through a tissue reference point to the coronal plane, and a second anterior-posterior projection through a probe reference point to the coronal plane;

computing a relative angle between the first and second projections and medial-lateral vector through the tissue reference point;

computing a distance between the first and second projections;

constructing an idealized breast map based on the relative angle and distance computed;

conforming the geometry of the recorded image to the idealized breast map; and

depicting a recorded tissue feature in the idealized breast map by translating the recorded position of the tissue feature in the scanned image to a corresponding position in the idealized breast map.

7. The method of claim 6, wherein the processor is configured to identify a relative coronal plane of the breast, a nipple-to-middle-of-chest-wall vector, medial and lateral boundaries, superior and inferior boundaries, a sagittal plane for the patient, a coronal plane for the patient, and a medial-lateral alignment for the patient.

8. The method of claim 6, further comprising scaling the scanned image to the size and shape of the idealized map.

9. The method of claim 6, wherein the processor is configured to apply trigonometric reconstruction to generate the idealized map.

10. The method of claim 6, wherein the processor is configured to apply geometric reconstruction to generate the idealized map.
