The present invention includes a method for targeted isolation, segmentation, and coloring of anatomic images, anatomic maps, points of interest, and regions of interest for dynamic, translated form generation. For example, this invention includes a method whereby a description of anatomy that includes an anatomic site, and optionally laterality and other descriptors, targets and isolates diagrams from an anatomic map library that fits the anatomy description. A point of interest on a layered, hierarchical map is visualized in relation to the borders of each isolated anatomic site above, below, on the same level along with translated human readable descriptions of the pin position relative to each layer. An anatomic region of interest is also visualized in relation to sites above, below, and on the same hierarchical or layer level. Targeted isolation of each layer provides visualization, translation, descriptions, and visual selection points for a visual, translated hierarchical travel method included in this invention. A dynamic anatomy library combines with other data to generate dynamically filled in and fillable forms with relevant visualizations, codes, translations, and data.

A record retrieval engine applies neural networks, computer vision, and artificial intelligence to re-create, analyze, categorize, and serve back record defined data to complete the loop.

Systems and methods for accurate determination of the position of an anatomic part of a subject in robotic assisted image-based surgery, using an inertial measurement unit (IMU) to determine the position and orientation of the anatomical part of the subject. The intrinsic drift of the IMU, which would make the IMU position measurements inaccurate, can be reset to zero regularly, at points of time when the subject's body is stationary. This can be achieved when motion from the subject's breathing and from the heartbeat are essentially zero. Such positions occur respectively when the respiratory signal shows the position of the breathing cycle to be at the end of the expiration phase, and the heartbeat signal represents a time in the diastole period of the subject's electrocardiographic cycle. When these two signal moments coincide, the IMU is essentially stationary, and its drift reset to zero.
