Claim 17:
18. A system comprising:
a first target configured to attach to a pelvis of a patient, the first target configured to provide positional information in up to six degrees of freedom to the optical sensor;
a second target configured to attach in a known positional relationship to an object, the second target configured to provide positional information in up to six degrees of freedom to the optical sensor, the object comprising a femur, a surgical tool or an implant;
a handheld registration device configured to define at least one axis of an anatomy of the patient;
a handheld sensor comprising an optical sensor configured to provide optical information and a measuring sensor configured to provide measurements for determining a direction of gravity; and
an intra-operative computing unit configured to:
receive, from the handheld sensor, first optical information for the first target and second target, and first measurements for determining the direction of gravity, the first optical information and the first measurements received for a registration step to perform a registration, the first optical information comprising information for the second target attached to the registration device to determine at least one axis relative to the anatomy;
receive, from the handheld sensor, second optical information for the first target and second target for a subsequent step of a surgical procedure, the second optical information comprising information for the second target attached to the femur of the patient, the surgical tool comprising an implant tool for a THA procedure or the implant for the THA procedure; and
determine and present measurements relative to the anatomy for the surgical procedure, wherein the measurements relative to the anatomy are determined from the second optical information, and in relation to the registration of the anatomy of the patient.
