View Edit Delete	TOY-1	However, during a surgical procedure obtaining the same level of precision and information about internal structures of the patient is not readily available. Typically, if a surgeon wants to confirm the location and/or orientation of unexposed structures of the patient during a procedure the surgeon may rely on medical imaging technologies available in an operating room during the procedure. However, access to such medical imaging technologies in the operating room during the procedure may not be practical or feasible due to the high costs of such equipment. In addition, stopping a surgical procedure to take intraoperative images of the patient interrupts the surgical procedure, can require reconfiguration of the surgical field, and extends the duration of the procedure. Extended procedures can require a patient to remain sedated with can increase risks of complications with the success of the procedure.	3	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	"Cortical bone" refers to a type of bone tissue. Cortical bone is a type of bone tissue typically found between an external surface of a bone and an interior area of the bone. Cortical bone is more dense and typically stronger structurally than other types of bone tissue.	34	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	The present disclosure discloses an intraoperative angle measurement apparatus, system, and/or method of use. Conventional medical imaging technologies enable a surgeon to gather accurate information about body parts and structures of a patient. This information can enable a surgeon to preoperatively plan the surgery and determine a desired set of steps, equipment and/or timing for the surgery.	46	Added by DJM 1 2022	1/19/22, 12:00 AM
