Medical 3D Prints are drastically changing how Doctors interact with their patients, as we begin to see just how useful a true 3D model is in getting across information to patients and other doctors. Jason Kirk, a Drexel University student, recently completed his Master’s Thesis on the topic, demonstrating the potential of 3D printed models in doctor’s office. Jason published his findings in a video, entitled 3D Printed Cardiac Imaging Data. You can watch the video below:

Objex Unlimited not only offers the service of printing 3D medical models from CT Scans or CAD files (see our 3D Printed CT scan of a human heart below), but we’ve also been working to improve the methods to deliver effective 3D Printed medical models. If you are interested in hearing more about our 3D printing services and to see some samples of our work please don’t hesitate to contact us.

For further reading, below is an excerpt from the article published about the thesis project on 3Dprint.com by Michael Moody called How Patient Specific 3D Printed Organ Replicas Help Patients Reach Informed Decisions.

“The basic question that he tackled was “is there value for surgeons and their patients in reviewing 3D printed anatomy replicas?” Kirk notes that in the past, surgeons used such things as X-rays, drawings, CT imaging and computer animation when communicating with their patients regarding anatomy issues. Today, however, most surgeons agreed that those methods limit the discussion to basic two dimensional representations, “which frequently confused complex spatial relationships.”

3D Model of Human Heart Use for Printing

During the video Kirk provides insight into the process of preparing 3D anatomy replicas. Initially, the healthcare professional begins with patient specific CT scan data which serves as the basis for developing the 3D replica. He indicates that patient specific data is then used in conjunction with a software program called “MiMiC.” By using the software program, he is able to prepare the model and isolate the area of interest, in this case the heart muscle.

The software allows the computer to save the graphic details of the model. It is then ready to complete using a polyjet 3D printer. This type of printer works by depositing layer after layer of liquid resin. This portion of the model is allowed to cure for 24 hours. The model is then removed from the printer and inspected for any errors. Once complete, a digital model can be used, as is, or with further editing to create a 3D stylized physical object. It is printed in two sections so it can provide a visual representation of the heart that allows for internal and external views without compromising either.

Additionally, Kirk obtained input from a panel of cardiac experts, including cardiovascular surgeons, radiologists, and researchers from the Mayo Clinic, Hahnemann University Hospital as well as Drexel University College of Medicine. The goal of the interviews was to determine if a 3D printed cardiac anatomy replica could be used to facilitate doctor-patient communications by providing a supplemental decision making aid.

3D Printed Heart Model

His research indicated “Cardiac anatomy replicas can be used to facilitate Doctor/Patient communication and supplement contemporary visualization techniques by providing accurate three dimensional data which offers additional haptic and spatial feedback specific to the patient’s anatomy and pathology.”

Or stated another way, Kirk determined that in order to overcome the limitations of two dimensional presentations, one needs to combine patient centered healthcare, patient specific imaging data, and additive manufacturing techniques such as 3D printing; to assist empowered doctors to better communicate with their patients. Ultimately, this should lead to better, and more informed decisions.

Kirk’s thesis would appear to offer additional support for the idea that patients who have the ability to observe 3D anatomy replicas of affected organs gain a better understanding of the issues involved. Replicas that are based on patient specific data afford the best opportunity for meaningful dialog.”
