About 3D Rendering

What is this service?

This on-line service aims to assist your surgeon by providing 3D visualisation of a complex anatomical problem from your standard CT scan data. An image processing technique known as 3D Volume or Cinematic Rendering (3DVR) is used to combine many individual cross-sectional CT images and create a photo-realistic 3D view of the relevant anatomy (see example below). These ‘volume rendered’ images alter diagnostic perception by showing the standard 2D information from an entirely different perspective, and can be used to supplement the evaluation of any body region. For example, in the context of abdominal hernia repair, 3DVR images can assist the surgeon’s pre-operative understanding to help plan an effective procedure.

An example of 3DVR: The images above are from the same patient, showing a recurrent fatty ventral hernia of moderate size that is nevertheless relatively subtle (green arrows). Compared with the standard CT image (left), the 3DVR image (right) better demonstrates the presence & extent of a widened abdominal midline with numerous complicating ‘swiss cheese’ hernia defects (appreciated as ovoid dark patches) in addition to the palpable hernia. This helps the surgeon to understand the full extent of the hernia ‘field’ and plan an effective hernia repair. Failure to address the additional swiss cheese defects would significantly increase the risk of subsequent hernia recurrence.

What is required?

  1. A formal written medical request from your surgeon that specifies the current clinical context, past surgical history and particular anatomy to be rendered.
  2. Access to the raw imaging data of your CT scan (in medical DICOM format). This can usually be sourced directly on-line if formal consent is provided and the contact details of the radiology practice that performed the scan are known.
  3. Time! The rendering process is a skilled, individualised, largely non-automated, and often time-consuming technique. This service aims for a turnaround time of 1-2 weeks.

What is delivered to your referring doctor?

  • A set of volume rendered images of print quality will be provided in digital (JPEG) format. The render quality of these images is directly related to the quality of the original CT data, which can sometimes be significantly limited or degraded by patient motion, inadequate scan parameters (e.g. CT slice thickness), and scan artefacts (e.g. streak artefact arising from metallic implants).
  • The image set will be labelled with patient name, ID and scan date (as assigned by the radiology practice that performed the original CT scan).
  • Additional labelling may be added where appropriate.
  • No formal diagnostic report is provided.
