Phantom production tool

1. A method of producing a flexible mold for a given anatomical part having at least two mold sections, comprising:

a) mounting a 3D model of the given anatomical part in an internal volume of a rigid thermally conducting housing formed from at least two rigid housing sections, dividing the internal volume between the 3D model and an interior wall of the assembled housing sections into two separate compartments with the 3D model straddling the two separate compartments;

b) locking the two housing sections together using a locking mechanism configured to allow expansion of the at least two rigid sections away from each other upon generation of internal pressure in the internal volume and contraction back together upon release of internal pressure;

c) injecting a liquid precursor of a flexible mold material separately into the two separate compartments through access ports located in a sidewall of each rigid housing section substantially enveloping the 3D model;

d) curing the liquid precursor in each compartment to produce two substantially separate flexible mold sections encasing the 3D model and venting any gases produced from the curing out of the interior volume through vent holes in each rigid housing section;

e) disassembling the two sections and removing each of the two separate flexible mold sections from its associated rigid housing section, removing the two separate flexible mold sections from the 3D model to give at least two sections of the flexible mold having an inner surface topography reflective of the outer surface topography of the given anatomical part and an inner volume corresponding to a volume of the anatomical part; and

f) producing a liquid access port and vent port in the two flexible mold sections aligned with liquid access ports and vent ports in their associated rigid housing section.

2. The method according to claim 1 wherein said liquid precursor is uncured liquid silicone and the flexible mold is made of silicone.

3. A method of producing an anatomical phantom of the given anatomical part using the housing and flexible mold according to claim 1 , including:

a) mounting each of the two flexible mold sections into its associated rigid housing section with the liquid access ports and vent ports of each aligned with the liquid access ports and vent ports of its associated rigid housing section;

b) locking the two rigid housing sections together using the locking mechanism;

c) injecting a liquid precursor to a material being used to form an anatomical phantom of the given anatomical part into an inner volume defined by the two sections of the flexible mold, inner volume having a size and shape substantially the same as a size and shape of the 3D model; and

d) inducing setting of the liquid precursor to produce the anatomical phantom and after the liquid has set, disassembling the thermally conductive rigid shell and the flexible mold and removing the anatomical phantom therefrom.

4. The method according to claim 1 , wherein prior to step a), producing the rigid 3D model by the steps of

a) acquiring imaging data of the given anatomical part of a patient to undergo a medical procedure on the given anatomical part; and

b) producing the rigid 3D model of the given anatomical part from the imaging data.

5. The method according to claim 3 wherein the material being used to form the anatomical phantom is selected to exhibit biomechanical properties of the anatomical phantom, optical properties of the anatomical phantom, or a combination of both.

6. The method according to claim 3 wherein said liquid precursor is a precursor to a polyvinyl alcohol cryogel.
