Integration of MRI and stereolithography to build medical models: a case study

Abstract

Presents the results of an investigation into the feasibility of producing models of human anatomy by linking MRI and stereolithography. Begins by describing the requirements for developing a link between the two technologies together with the major problems that this involves. Describes the processes undertaken to enable the creation of a model of a human brain. The model showed excellent anatomical details and demonstrated that the technique of linking MRI and stereolithography is entirely feasible. However, the preparatory work required prior to building the model showed that there are many difficulties associated with transferring and processing the imaging data. Recommendations are made as to how this technique needs to evolve.

MRI monitoring and non-destructive quality measurement of polymeric patterns manufactured via stereolithography

“…Polymers, composites, catalysts and other advanced materials, processes of polymerisation, hardening, heat and mass transport have been successfully studied by MRI. Nevertheless, until now, the implementation of MRI in additive manufacturing has focused primarily on the biomedical applications; for example, based on Nuclear Magnetic Resonance (NMR) images of tissues and structures, the digital prototypes were reconstructed by the subsequent 3D printing of the appropriate parts [14][15][16][17]. In one work [18], a special controllable phantom intended to substitute the real bone tissues was fabricated via SL and then it was used for MRI investigation of pore geometry.…”

Additive manufacture of custom radiation dosimetry phantoms: An automated method compatible with commercial polymer 3D printers

“…The disruptive nature of additive manufacture has enabled commercial and clinical manufacturing outcomes not otherwise feasible with traditional manufacture [19]; Including: structural components for high-value aerospace and automotive applications [20][21][22]; structural medical implants [23][24][25][26][27]; scaffolds for reconstructive surgery [28]; medical anatomical models for treatment planning [29], and polymer implants for reconstructive surgery [30,31].…”

A review of the issues surrounding three-dimensional computed tomography for medical modelling using rapid prototyping techniques

“…The medical modelling process requires the relevant anatomy to be captured in a three-dimensional format and although a number of medical imaging technologies have been successfully employed to make models, including MRI 19 and Ultrasound 20 , volumetric Computed Tomography (3D CT) is by far the commonest imaging modality. The 3D medical image data is processed, mathematically modelled and subsequently transferred to a rapid prototype model provider for manufacture.…”
