Abstract: Imaging systems and methods compensate for wigwag movement of a C-arm fluoroscope to refine camera pose estimates. The methods involve computing a primary movement axis from samples of markers in fluoroscopic images of a fluoroscopic sweep of a structure of markers and processing the primary movement axis to obtain a secondary movement axis. The methods further involve aligning two-dimensional samples of each marker with the primary and secondary movement axes to obtain an aligned signal and determining a difference signal for a secondary component of the aligned signal. The difference signal is then converted to a rotation axis translation signal. The method further involves estimating a 3D position of the rotation axis. The estimated pose of the C-arm fluoroscope is then refined to compensate for the wigwag movement using the rotation axis translation signal and the estimated 3D position of the rotation axis.

Abstract: A mammography system includes a biopsy guidance system that employs a simplified robot arm support, to enable previously unusable locations for the mounting of the biopsy device directly to the mammography system, such as on a compression paddle, combined with a vision guidance and control system. The vision system operates to determine the position of the biopsy device and the biopsy needle tip, as well as to control the movement/operation of the biopsy guidance system, such as movement to the final end-pose or pre-firing position of the biopsy device to perform the biopsy procedure. The vision system utilizes one or more cameras to visually determine the position the biopsy device relative to a region of interest being biopsied within the required tolerances for the biopsy procedure without the need for precise positional information to be provided by the biopsy guidance system to the mammography system.
