Claim 8
Dependent Claim
78 words
A pelvimetry phantom comprising a replica of at least part of the anterior section of the bony pelvis and a replica of at least part of the posterior section of the bony pelvis, said sections being separably connected to form a complete replica of the bony pelvis of a pure or mixed anatomical type, where the posterior section further comprises separably connectable blocks replicating (a) the sacrum and coccyx, (b) the right ilium, and (c) the left ilium.

A pelvimetry phantom comprising a replica of at least part of the anterior section of the bony pelvis and a replica of at least part of the posterior section of the bony pelvis, said sections being separably connected to form a complete replica of the bony pelvis of a pure or mixed anatomical type, where the posterior section further comprises separably connectable blocks replicating (a) the sacrum and coccyx, (b) the right ilium, and (c) the left ilium, and the anterior section further comprises separably connectable blocks replicating (d) the right ischium and pubes and (e) the left ischium and pubes.
Claim 11
Dependent Claim
101 words
A pelvimetry phantom comprising a replica of at least part of the anterior section of the bony pelvis and a replica of at least part of the posterior section of the bony pelvis, said sections being separably connected to form a complete replica of the bony pelvis of a pure or mixed anatomical type, where the posterior section further comprises separably connectable blocks replicating (a) the sacrum and coccyx, (b) the right ilium, and (c) the left ilium, and the anterior section further comprises separably connectable blocks replicating (d) the right ischium and pubes and (e) the left ischium and pubes.
