    Left knee - Skin model STL file from converted CT scan

    The knee joint is formed by three bones: the femur, the tibia and the patella. the knee joint is the largest synovial joint and provides the flexion and extension movements of the leg as well as relative medial and lateral rotations while in relative flexion.

    The knee joint articulations are two condylar joints between the femur and the tibia as well as a joint between the patella and the femur. Although the fibula is closely related to the knee joint but it doesn't share in articulation.   The knee joint is also formed by some ligaments and cartilage called (mensci) which are best imaged by MRI.   This 3D model was created from the file STS_039   The original CT examination can be reviewed at: The 3D bone model created from this scan can be reviewed at: The 3D muscle model created from this scan can be reviewed at:

    Chest wall - Skin model STL file from converted CT scan

    The chest wall (thoracic cage) is composed by twelve pairs of ribs laterally and the sternum anteriorly. The ribs are attached to the dorsal vertebrae (thoracic spine) posteriorly and along their costal cartilage to the sternum.
      The thoracic cage main function is to protect the vital chest organs such as the heart and lungs.   There are five muscles that make up the thoracic cage; the intercostals (external, internal and innermost), subcostals and transversus thoracis.   This 3D model was created from the file STS_040 for a 57 years old female with breast implants.   The original CT examination can be reviewed at: The 3D bone model created from this scan can be reviewed at: The 3D muscle model created from this scan can be reviewed at:

    Whole Body - Skin model STL file from converted CT scan

    Whole body: chest, abdomen and pelvis
     
    The chest wall (thoracic cage) is composed by twelve pairs of ribs laterally and the sternum anteriorly. The ribs are attached to the dorsal vertebrae (thoracic spine) posteriorly and along their costal cartilage to the sternum. The thoracic cage main function is to protect the vital chest organs such as the heart and lungs.   The cervical spine is the upper most spines forming the spinal column, extending from the skull base to the level of the thoracic vertebra (the spines with attached ribs). The cervical spines are usually seven and the main function is to support the skull and to protect the spinal cord.   The dorsal (thoracic) spine forms the middle portion of the vertebral column extending below the seventh cervical vertebra to above the first lumbar vertebra. The dorsal spine is formed by twelve vertebral bodies.
    The vertebrae forming the dorsal spine are unique in shape as they are the only vertebral bodies articulating with ribs.   The lumbar spine represents the mid-lower segment of the vertebral column and is composed of five adjacent vertebrae. They are convex anteriorly to form a lumbar lordosis. The lumbar spine facet joints allows limited movements and rotation.   The bony pelvis is formed by 4 bones; a pair of hip bones, the sacrum and the coccyx. The bony pelvis supports the pelvic viscera and works to transmit force from the axial skeleton to the lower limbs.
    The two hip bones are related anteriorly by the symphysis pubis and posteriorly to the sacroiliac joints bilaterally.

    Pelvis and Hip - Skin model STL file from converted CT scan

    The bony pelvis is formed by 4 bones; a pair of hip bones, the sacrum and the coccyx. The bony pelvis supports the pelvic viscera and works to transmit force from the axial skeleton to the lower limbs.
    The two hip bones are related anteriorly by the symphysis pubis and posteriorly to the sacroiliac joints bilaterally.
      The hip joint is a large synovial socket and ball joint which is formed by the femoral head (the ball) and the acetabulum (the socket). The acetabulum is formed by pelvic bones; the ilium, the ischium and the pubis. The hip joint represents the articulation between the lower extremity and the axial skeleton and allows a high degree of mobility while being stable.   This model shows parts of the fingers as the patient's hands were set beside the body.   The CT scan is derived from the file STS_037   The original CT examination can be reviewed at: The 3D bone model created from this scan can be reviewed at: The 3D muscle model created from this scan can be reviewed at:

    Left Shoulder - Skin model STL file from converted CT scan

    The shoulder joint is a large and complex ball and socket joint formed by the humerus and the scapula (glenohumeral joint) while the clavicle join the acromion to form the acromioclavicular joint.
      The shoulder joint is the most mobile joint in the human body on cost of instability. Lot of elements share to compensate the instability such as rotator cuff muscles, tendons and ligaments as well as the glenoid labrum.   Muscles of the shoulder joint
    The rotator cuff: supraspinatus, infraspinatus, teres minor and subscapularis
    Posterior muscle group: deltoid, latissimus dorsi and teres major
    Anterior muscle group: pectoralis major and coracobrachialis   This 3D model was created from the file STS_037   The original CT examination can be reviewed at: The 3D bone model created from this scan can be reviewed at: The 3D muscle model created from this scan can be reviewed at:

    Right Shoulder - undifferentiated pleomorphic spindle cell sarcoma - Skin Model STL file from converted CT scan

    This 3D model represents a case of undifferentiated pleomorphic spindle cell sarcoma implicating the right parascapular region of a 61 years old male. The patient represented with lung metastasis and was treated by surgical excision follower by chemotherapy as well as radiotherapy.
    A cross sectional CT image is attached showing the lesion in axial, coronal and sagittal planes.   Unfortunately pleomorphic undifferentiated sarcoma has an aggressive biological behaviour and a poor prognosis.   Pleomorphic undifferentiated sarcomas can occur almost anywhere in the body, they have a predilection for the retroperitoneum and proximal extremities. They are usually confined to the soft tissues, but occasionally may arise in or from bone.   This 3D model was created from the file STS_037   The original CT examination can be reviewed at: The 3D bone model created from this scan can be reviewed at: The 3D muscle model created from this scan can be reviewed at:

    • Hi Mike - starting with Cone beam CT files.  Will play with Hounsfield settings next time.  For this particular case I learned enough on Slicer and Meshmixer to get the job done. 
    • You are diving into the deep topic of medical imaging scans for 3D printing. I wrote a blog article on how to get the most out of your scan here. Take a look as it is very helpful.   3mm is not bad for a CT scan for 3D printing.  In order to understand why the radiology department created 3 mm slices, you need to understand how CT scans work. Modern CT scanners do not acquire data in slices. Rather, the acquisition is helical. The patient moves in the scanner on the Z axis at a fixed speed, while the x-ray tube spins around that axis during acquisition. As a result, relative to the body, the x-ray tube moves around like a helix, i.e. corkscrew. The raw data from this acquisition is stored in memory in the CT scanner. It is then reconstructed into flat slices that can be of any thickness anywhere from 0.5 mm to 5 mm.   Thinner slices are not always better however. There is a fixed number of x-ray photons that were acquired during the scan. When the slices are created after the fact, the data that those photons created is spread among the slices. If you have a lot of very thin slices then there are few photons per slice. Just like with a handheld camera when you shoot in low light, having a low number of photons results in a grainy image. The exact same things happen with a CT scanner. Thin slices tend to be very grainy and it can be difficult to detect abnormalities when the image quality is poor. Thicker slices on the other hand are fewer in number and have more photons per slice and thus are less grainy. Think of a nice photograph from a handheld camera on a bright sunny day. There are so many photons to make the image, the image is crystal clear. Thicker slices, while giving a higher quality image, are also thicker, and very small structures are harder to see.   Therefore, if you had a CT scan and reconstructed 0.5 mm slices, those images would be much grainier and of lower quality than if you had reconstructed with 5 mm slices. When the scan is being taken the radiologist determines what slice thickness is the best for diagnosing the problem at hand. If you're getting a CT scan of the abdomen for appendicitis, you will get 5 mm slices. If you have a problem with your middle tier and are getting a CT scan of the mastoid, you'll probably get 0.5 mm slices.   It should be noted that the raw data from the scan acquisition takes up a lot of memory. While the reconstructed slices are saved in the hospitals radiology system, the raw data from the scan is stored on the physical scanner itself. Typically after a few days that data is purged to make room for new scan data. So, after a few days it is not possible to generate any new slices from the scan, as the raw data has been purged.   My guess is that 3 mm slices is as good as you are ever going to be able to get from your scan. To reduce the stairstep artifact, run a smoothing algorithm on your model. This should reduce that appearance.   I hope this helps   Dr. Mike    
    • 1) Nothing in this forum should be considered medical advice. 2) The scan shows some extent of pectus excavatum. Heart is a bit displaced as a result. 3)  Evaluation of the heart itself is poor because the scan was not protocoled to examine the heart (i.e. no ECG gating). My guess is they were looking for PE, and there is no obvious one.   Good luck
    • If you increase the threshold value (150->250 Hounsfield units), that will tend to include less bone in the model. If decrease it, more bone will be included.    Just want to check -- are you starting with a CT or an MRI. CTs work better.   Hope this helps.   Dr. Mike
    • I use 3D slicer and the segmentation module. It takes a little time to get familiar with the tools, but they can be pretty powerful.   I just did this kidney yesterday, including the kidney tissue, renal collecting system, artery and vein.    FYI, we are building the ability to automatically segment organs into democratiz3D. Right now it only supports creation of bone models, but in the future auto segmentation of organs will be a feature.    Hope this helps,   Dr. Mike
