3D Printable Patient Face and corresponding PET-CT Data for image-guided Therapy

<p>The patient’s face (Face.stl) can be 3D Printed and then used for a marker-less face detection and registration with the CT scan. This is of particular interest for researchers/developers who work in the field of image-guided therapy in the facial area.</p> <div><br></div><div>Please use the following citations if you use them in your work:</div><div><br></div>J.

Results from the evaluation questionnaire for each subject using a six point Likert rating.

<p><i>Median</i> is the median value of the four subjects and <i>Error</i> describes the superimposed standard error. <i>Q11</i> is a <i>yes/no</i> question where <i>no</i> equals a value of <i>zero</i> and <i>yes</i> equals a value of <i>6</i>. The time <i>T</i> is measured in minutes.</p

The patient's skull (white) with an applied baseline (green) are shown on the left side, where the normal vector <i>N</i> and the direction vector <i>D</i> are drawn for the placement of the ring elements.

<p>The ring element itself is shown in the right image, where the normal vector <i>N</i> and direction vector <i>D</i> (red), which have to be aligned with the vectors from the baseline, are illustrated.</p

Bridge building principle with triangulation.

<p>Green crosses mark the corner of the ring element's plane side. To each baseline point (green points) a rectangle (light blue lines) is constructed. Rectangle triangulation, spanned by the two starting nodes (<i>N1</i> and <i>N2</i>) and two opposing nodes of the previous constructed rectangle (<i>N3</i> and <i>N4</i>). Node <i>N1</i>, <i>N3</i> and <i>N4</i> build a triangle <i>T2</i>, and Nodes <i>N1</i>, <i>N2</i> and <i>N3</i> build the second triangle <i>T1</i>.</p

Computer-aided position planning of miniplates to treat facial bone defects - Fig 12

<p>Example result containing all three available implants each located at a position where they generally are applied (left). For better illustration, the single implants are extended portrayed as well on the right side. The plate could easily be positioned according to the underlying bone contours by the used software module.</p

Constructed network using the MeVisLab prototyping environment, including self-implemented modules named <i>CurvatureCalc</i> for baseline calculation and <i>ImplantGen</i> for generating the implant models.

Illustration of the baseline determination.

<p>The direction vector <i>D</i> (green) is set up parallel to the initial point's (red star) direction vector (green). The direction vector is perpendicular to the initial point's normal vector (purple). The origins of the cast rays (brown) are translated along the direction vector and checked for intersections.</p

Image of real patient x-ray data suffering from a mandibular angle fracture (left angle).

<p>Left image shows the untreated defect. The result of the treatment with applied miniplates after bone repositioning is shown on the right part of the figure.</p
