Automatic Segmentation

Once you open CT image data, mediCAD® 3D Spine performs an automatic segmentation of the 3D model.

During this process, your recording is precisely analyzed and compared to the data repository of the software. This allows for an automatic match and precise allocation of all detected vertebrae and disks in the recording. With the aid of a spine diagram, the detected vertebrae are depicted schematically and can be adjusted manually if necessary.

The automatic segmentation considerably enhances the subsequent planning and after all enables the automatic measurements, automatic insertion and placement of pedicle screws in the correct vertebrae, as well as spondylodesis.

Hybrid Planning 2D & 3D

Innovative hybrid planning solution


Our easy to use, innovative hybrid planning solution is one of the most powerful core functionalities of mediCAD® 3D Spine.

For the very first time it is now possible to load 2D and 3D image data of a patient simultaneously into a planning. By setting just very few reference points, both images are correlated with each other and displayed at the same time.



Due to complex algorithms and elaborate analysis of the loaded image data, the differences in both images (resulting e.g. from being taken in standing or prone position) are automatically taken into consideration and converted. This allows, for example, the assessment of a lordosis under strain or in relief.

All other functionalities of mediCAD® 3D Spine described on the next pages can be automatically performed in 2D as well as 3D thanks to hybrid planning.
No matter if measurements, spondylodesis or complex osteotomies - all performed actions are displayed and updated in real time in all images and views.

 

 

Osteotomy

mediCAD® 3D Spine offers the planning of osteotomies on the vertebrae


In order to adjust short and long range kyphoses, lordoses and scolioses with the purpose of restoring a harmonic spine profile, mediCAD® 3D Spine offers the planning of osteotomies on the vertebrae.

By specifying individual cuts or cut areas, you can perform one or multiple osteotomies. The resected areas can be moved or rotated as required. All measurements are automatically adjusted and reflect the new situation after performing the correction.
This way, various scenarios can be simulated and tried out, finding the ideal result for the patient. Thanks to hybrid planning, all osteotomies performed on the 3D image are automatically transferred to the 2D image, and vice versa.

 



The results of each performed action on the sagittal profile of the patient can be monitored and illustrated in real time. If specified, you can also perform an automatic alignment based on previously measured parameters after performing an osteotomy.
mediCAD® 3D Spine optionally also suggests the optimal resection angle. Hereby, a harmonic spine profile can be automatically restored.

 

Automatic measurements

autom bemassung11 enOn CT images that have already undergone automatic segmentation, you can perform and document a number of conventional measurements automatically:
- Scoliosis using Cobb’s method
- Scoliosis using Ferguson’s method
- Interpedicular distance
- Lordosis
- Kyphosis
- Intervertebral disc height
- Intervertebral disc angle
- Spondylolisthesis
- Instability using van Akkerveeken’s method


The results of the measurements are both displayed directly on the 3D model and recorded in a structured list of results. Where possible, an analysis based on the normal ranges is performed and positive or negative deviations are highlighted with a corresponding colour.

This way, mediCAD® 3D Spine helps save you most of the time that you used to need to spend on these tasks. This gives you significantly more time for consulting with your patient and preparing for any surgery.

Conventional measurements
In addition to the automated measurements, all conventional measurements can still be performed manually. mediCAD® 3D Spine has the option to perform the following measurements in simple and comfortable operation:

Automatic measurements- Distance measurement
- Angle measurement
- Risser’s sign
- Scoliosis using Cobb’s measurement
- Scoliosis using Ferguson’s measurement
- Interpedicular distance
- Spinal canal width
- Spinal canal diameter
- Lordosis
- Kyphosis
- Atlantodental interval
- Dens perpendicular
- Intervertebral disc height
- Intervertebral disc angle
- Spondylolisthesis
- Instability using van Akkerveeken’s method
- Sacral angle

 

Sagittal Balance

Thanks to hybrid planning and the resulting interaction between x-ray and CT images, mediCAD® 3D Spine offers a significant improvement of your usual procedures - as opposed to the sagittal balance measurements usually performed on 2D images only.
Measurements taken on the 2D image can be automatically applied and therefore used as a basis for subsequent planning on the 3D model.

mediCAD® 3D Spine allows the measurement of the sagittal balance in a single function intuitively guiding the user. By placing just a few required designation points, all values are automatically calculated, drawn in and measured. The measuring results are, like with all automatic measurements, logged in a structured list of results and, when applicable, evaluated with regard to the normal values.

The following values known from spine surgery can be measured by using this function:

- Sacral Slope SS
- Pelvic Tilt PT
- Pelvic Thickness SPT
- Pelvic Thickness CS
- Pelvic Angulation PA
- Pelvisacral Angle PSA
- Pelvic Lordosis Angle PLA
- Pelvic Incidence PI

Subsequently, you can also measure and draw in the following additional values.

- T9 Tilt
- C7 Tilt
- C7 Plumb Line

By just a few mouse clicks, mediCAD® 3D Spine provides all important data you need for further planning.

 

Pedicle Screws and Implants

What screw length do I require?
What is the ideal entry angle?
How deep should or may the screw be drilled in?
How long is the required rod and in which way does it have to be bent?
And what implant is suited best for the particular spine situation?

These and many more questions are answered by the convenient possibilities offered with mediCAD® 3D Spine.

The screw tool allows you to select from various screw types and lengths. On a segmented 3D model, you can additionally select the required vertebra and pedicle side. The pedicle screw is now automatically inserted into the 3D model in a standard position. You can now adjust, rotate, move or drill the screw or switch to another screw type or length entirely.

The implant tool allows you to select from various spine implants, such as cages, plates, vertebra and disk prostheses. These can be also placed into the 3D model and further adjusted as needed. While doing so, you can use the implant tool to filter the implants based on manufacturer, type, material and size. You can also list your personal favorites only, or those used in your hospital.

In case of multiple views (e.g. 3D model and 2D slices), each adjustment is automatically displayed in all views. When working in hybrid planning mode, an automatically adjusted depiction is displayed. This allows you to try out multiple alternative versions, finding the ideal position for the individual situation of the patient and assessing it with regard to various aspects.

All selected and inserted implants are logged in the structured result list, including all relevant parameters, and can be used for further planning and pre-operative preparations.
Thanks to more than 15 years of cooperation with a great number of international spine manufacturers, mediCAD® 3D Spine contains the most up-to-date know how and a monthly updated and extended implant database.

 

Spondylodesis

spondy1 1

mediCAD® 3D Spine offers a convenient, innovative and easy to use solution for spondylodesis planning.

You are guided by an automatic tool and - optionally with the interaction of sagittal balance and previously performed osteotomies - can simulate the restoration of a healthy patient anatomy.

After selecting all required vertebrae and pedicle sides, you can automatically insert all required screws and rods.
Within the hybrid planning mode, all results are automatically converted and displayed in the respectively other image.

 

All screws and rods inserted with this function are logged in the structured result list, including all relevant parameters, and can be used for further planning and pre-operative preparations.

Visualization

Each recording and every planning is different and and pursues a different purpose or requires another approach. It is therefore sometimes required to display the image data from a different point of view.

mediCAD® 3D Spine offers a variety of different visualization settings.
Besides the all around viewable 3D model, you can also view individual 2D slices in axial, sagittal or coronal plane. Additionally, you can display and view the 3D model in several different perspectives at the same time.

Organs and tissue can be displayed and hidden, you can view into the inside of the patient and consider the pathways of blood vessels and muscles for your planning. Surfaces can be displayed with various filters and parameters.
Individual vertebrae can be displayed or hidden. You can directly focus the view on them or display them as a clipped selection and highlight them with a color.
