SURGICAL SIMULATION

3D printing enables the rapid creation of a range of anatomical models that are ideal for Surgical Simulations. Anatomical models are made to order, either from stock data or from patient specific scans. They are created in a variety of materials to suit the purpose and can include bespoke elements so a range of surgical skills can be assessed. The use of anatomical models for high fidelity surgical simulations is on the rise due to strict animal protection laws and barriers in using cadaveric anatomical models avoid any such issues.

3D PRINTED PHANTOMS FOR CT ANALYSIS

Off-the-shelf phantoms are expensive and non patient specific. Minimising CT scan parameters are especially important for pediatric patients and difficult to accurately plan. Using advanced 3D printing polymer materials, we can create 3D printed patient specific models that are comparable to real bone under CT when measuring with hounsfield units. This enables the clinician to minimise exposure to their patients.

3D PRINTED PHANTOMS FOR THYROID TREATMENT  ANALYSIS

With 3D printed phantoms, we can assist your organisation with Radiodosimetry research, in order to understand exposure of radiation to surrounding tissues to establish correct dosage limits for radiotherapy. This thyroid phantom was 3D printed with radiopaic materials to mimic neck tissue/thyroid gland.

IMPROVING RADIATION THERAPY ACCURACY

The continuing evolution of 3D printing technologies have provided the ability to manufacture re-producible and sophisticated 3D printed biomedical phantom models that accurately recreate areas of human anatomy and mimic human tissue. These models are used by clinicians to enhance the surgical planning process such as allowing for more accurate dosimetry measurements that minimises the impact of often invasive surgical procedures on the patients longer term rehabilitation.

3DLP were asked by an leading NHS Trust Foundation to develop and manufacture a patient specific 3D printed liver for a patient with liver cancer who was about to undergo radiation treatment.There are multiple approaches available for treating patients with liver tumours, including ablation, embolization, targeted therapy, immunotherapy, chemotherapy and radiation therapy. Radiation therapy is one of the most effective methods but comes with its own risks and complexities. Accurate dosage measurements for radiation therapy is critical in providing effective treatment. The normal procedure for pre-assessment and planning prior to the interventional procedure relies on the clinicians looking a variety of patient image data scans. The subsequent procedure uses X-rays to provide the targeted radiation dose for the area of interest. There are currently few options for planning other than CT/MRI scans shown on a 2D screen. The 3D printed phantoms manufactured allowed the surgeons to better understand the patients anatomy and by using the measured dosage and known cavity volume for the patient, the surrounding exposure on the liver could be estimated.
