  16. Planmeca ProMax 3D ProFace • The first CBVT unit integrated 3D surface scan • CBVT volume and 3D photo in one scan • 3D photo acquisition can be acquired separately • Totally radiation-free process

  17. Planmeca ProMax 3D ProFace • Lasers scan face geometry • Digital cameras capture colourtexture • Software calculates information into a 3D photo • No additional equipment required; all components are integrated to sensor housing

  18. SmartPan system • Images are taken with the same flat panel 3D sensor • Work flow is the same as in 2D imaging programs • Same patient positioning • Same image processing parameters • Frames grabbed with slit beam and narrow sensor area • Tomosynthesis applied to calculate the panoramic images

  19. SmartPan system • ~2000 frames, snap shots, are taken during the panoramic scan • 9 different panoramic layers with 2 mm shift are calculated from the frames • +1 panoramic image in which the layer is optimised automatically

  20. SmartPan system • 10 panoramic images are saved as a stack • You can browse the images and select the best

  21. 3D Mid optimized SmartPan Optimized SmartPan takes the panoramic image only from teeth area • Reduces the patient dose

  22. 3D Mid optimized SmartPan + TMJ TMJ’s can be imagined separately • Optimal imaging angle for TMJ’s • Images are save in a study in Romexis

  23. Planmeca Romexis • 2D Imaging • 2D Implant Planning • 3D Imaging • 3D Explorer • 3D Cross Sections • 3D Implant Planning • 3D TMJ • 3D ProFace • Exporting and distributing images • Printing & Reporting • Patient & User Management • Radiology Module • Integration / Compatibility

  25. Planmeca ProMax 3D Mid and cephalometry • Digital cephalostat is ideal for cephalometry • all information for orthodontic planning • lower radiation dose • faster procedure • 3D to be used for detailed e.g. occlusion views, impacted teeth etc. if needed • Same Promax unit for both studies • Optimum for orthodontic imaging

  26. Cone beam 3D technology Flat panel detector axis of rotation object X-ray source Line detector Movement of translation and axis of rotation object X-ray source • Planmeca ProMax 3D works with cone beam computed tomography (CBCT) principle. • CBCT uses wide conical or pyramid shaped x-ray beam instead of narrow fan beam. • The 3D image is one 3-dimensional volume, not a pile of narrow slices. • CBCT scan is only one rotation around the patient. Medical CT needs several rounds around the patient. • CBCT: • is faster • has lower dose • has better resolution

  27. 3D Technology • Snap shot images taken with synchronized X-ray pulses • Stroboscopic effect for maximum clarity of the images • Accumulated X-ray exposure time is 2.8 – 18s – reduced dose • Proprietary 3D reconstruction algorithm • Voxel size 100, 200 or 400 µm depending on resolution mode and volume size • Resolution up to 5 lp/mm (Nyquist)‏

  28. ProMax 3D Mid Scanning • Symmetric scanning • C-ram rotates • Magnification 1.8x • Scan angle 210° • 300 - 500 frames • Max. volume Ø70 x 70 mm • Asymmetric off-set scanning • Elbow arm rotates • Magnification 1.44x • Scan angle 360 deg • 450 - 600 frames • Max. volume Ø160 x 90 mm

  29. Asymmetric off-set scanning • Sensor shift changes the acquisition geometry and reduces the final image quality • The shift of whole c-arm keeps the acquisition geometry constant and produces better final image SCARA!

  30. Isotropic voxel • CBCT has always an isotropic voxel • The reconstruction can produce any size of voxel • The voxel is always perfect cube • The measurements are exact • Voxel size is typically 0.1 – 0.5 mm • CT has an anisotropic voxel • The voxel is always a “brick” • The pitch (= distance between spiral rounds = layer thickness) varies and causes distortion in the 3D measurements. • The layer thickness is typically 0.5 – 0.8 mm

  31. 3D Technology • Pulsed X-ray produces sharp images with less dose.

  32. 3D Technology – Flat Panel • Planmeca ProMax 3D flat panel imaging chain • Conventional imaging chainwith Image Intensifier X-ray Tube – Patient – Flat Panel - Digital Image X-ray Tube – Patient – Image Intensifier – TV Camera – Digital Image Modern Flat Panel Technology for maximum performance

  33. 3D Technology – Flat Panel • Image intensifier has both distortion and brightness non-uniformity which is absent from the flat panel detector • Image intensifier needs periodical maintenance. It has limited life span 3-6 years. • It is sensitive to magnetic or electrical fields. • It is over 60 years old technology.

  34. Flat Panel vs Image Intensifier • Image intensifier image quality decreases sharply over time. Flat panel’s life time is longer.

  35. 3D technology – Tube Current Modulation less more • Different attenuation properties across and along the patient's head • Tube current (mAs) can be dynamically adjusted • Reduces patient dose and improves image quality

  36. Radiation dose • Modern low dose medical CT: 685 - 1400 µSv (ICRP 2008) • Radiation dose of CBCT: 20 - 1000 µSv • ProMax 3D: 28 - 122 µSv • Panoramic image 3 – 23 µSv • ProMax pan: 10 – 23 µSv • ProMax SmartPan: 12.5 – 30 µSv • Intraoral image <8 µSv
