Image alignment devices and associated methods

A surgical kit comprising:

• an instrument guide including one or more apertures dimensioned to guide a surgical device, the instrument guide adapted to contact an anatomical surface of a patient based on a surgical plan;
• and
• an alignment guide securable to the instrument guide at one or more interfaces, the alignment guide comprising:
• a guide body including a cavity, a foreground sight and a background sight on opposite sides of the cavity, and first and second alignment openings interconnected by the cavity;
• wherein the first and second alignment openings extend along respective reference planes that intersect at the foreground and background sights to establish respective pathways for a set of laser beams projectable onto the background sight;
• and
• wherein the foreground and background sights are visually alignable with each other to indicate an orientation of the instrument guide relative to a field of view of an imaging device.

A system for surgical imaging comprising:

• an imaging device including a set of lasers operable to emit laser beams along respective paths oblique to a field of view of the imaging device such that the laser beams intersect each other adjacent to an optical center of the field of view;
• and
• an alignment guide comprising:
• a radiopaque guide body;
• a foreground sight and a background sight visually alignable with each other to indicate an orientation of the guide body relative to the field of view of the imaging device;
• and
• a set of alignment openings along an exterior of the guide body;
• wherein the alignment openings extend along respective reference planes that intersect the foreground sight and the background sight, and the alignment openings are dimensioned to permit a projection of the respective laser beams onto the background sight.
