<p>Holography is a method of creating three-dimensional images
called holograms. They are made by superimposing a second wavefront - usually
defined as reference beam - on the wavefront of interest, thereby producing an
interference pattern which is then recorded on a physical medium (1).</p>
<p>Holograms are used in many fields like logistics, search and
rescue operations, military missions and biomedicine, in particular surgery. At
pre-operative level, 3D holograms can be used to maximize information on
patient’s anatomy and help planning of the best surgical strategy. The surgeon
can use 3D holographic models to assess tumor location and extension as well as
its relation with closer structures. Moreover, from a cognitive point of view,
3D holographic preoperative assessment provides surgeons with a valuable
support both in spatial imagination and mental rotation (2).</p>
<p>Here we report a preoperative holographic assessment - from
a standard preoperative CT scan – of a patient undergoing left upper lobectomy
for cancer. The left upper lobe usually presents the higher variability grade
in terms of vascular anatomy, thus maximally benefitting from preoprative 3D
holographic evaluation.</p><p><br></p><p></p><p>References</p><p><br></p>
