Abstract
The present invention relates to a method of producing a phantom resembling a human or animal organ or tissue, the phantom comprising at least one first region having at least one tissue like property and at least one cavity having a plurality of hollow branches connected thereto, with at least some of the plurality of hollow branches being formed such that they project into the first region having tissue like properties. The invention further relates to a method of making the first structure and to a corresponding phantom.
Claims19
A method of producing a phantom resembling a human or animal organ or tissue, the phantom comprising at least one first region having at least one tissue like property and at least one cavity having a plurality of hollow branches connected thereto, with at least some of the plurality of hollow branches being formed such that they project into the first region having tissue like properties, the method comprising the steps of:
- making at least a first structure having an average root mean square error of less than 2 mm and a shape that resembles the shape of the at least one cavity and of the interior of the plurality of branches connected to the at least one cavity;
- placing said first structure in a phantom mold having an inner shape that resembles an outer shape of the phantom;
- filling the phantom mold with a material that has the at least one tissue like property to form the phantom;
- and
- removing the first structure from the phantom in order to form the one cavity having a plurality of hollow branches connected thereto within the phantom, the phantom having both an anatomically correct outer shape and an anatomically correct inner shape.
A method of making a phantom, the phantom comprising at least one first region having at least one tissue like property and at least one cavity having a plurality of hollow branches connected thereto formed by at least a first structure having an average root mean square error of less than 2 mm, with at least some of the plurality of hollow branches being formed such that they project into the first region having tissue like properties, the method comprising the steps of:
- producing a positive plug of the first structure;
- coating the positive plug with an elastic material to form a first structure mold that once cured maintains an outer counter of the positive plug;
- mechanically removing the cured first structure mold;
- filing the first structure mold with a material to form the first structure;
- and
- removing the first structure from the first structure mold, the phantom having both an anatomically correct outer shape and an anatomically correct inner shape.
A phantom resembling a human or animal organ or tissue, the phantom comprising at least one first region having at least one tissue like property and at least a first cavity having a plurality of hollow branches connected thereto, the phantom being obtainable by a method of producing a phantom resembling a human or animal organ or tissue, the phantom comprising at least one first region having at least one tissue like property and at least one cavity having a plurality of hollow branches connected thereto, with at least some of the plurality of hollow branches being formed such that they project into the first region having tissue like properties, the method either comprising the steps of:
- making at least a first structure having an average root mean square error of less than 2 mm and a shape that resembles the shape of the at least one cavity and of the interior of the plurality of branches connected to the at least one cavity;
- placing said first structure in a phantom mold having an inner shape that resembles an outer shape of the phantom;
- filling the phantom mold with a material that has the at least one tissue like property to form the phantom;
- removing the first structure from the phantom in order to form the one cavity having a plurality of hollow branches connected thereto within the phantom;
- or the method comprising the steps of:
- producing a positive plug of the first structure;
- coating the positive plug with an elastic material to form a first structure mold that once cured maintains an outer counter of the positive plug;
- mechanically removing the cured first structure mold;
- filing the first structure mold with a material to form the first structure;
- removing the first structure from the first structure mold;
- and
- the phantom having both an anatomically correct outer shape and an anatomically correct inner shape.
A phantom resembling a human or animal organ or tissue, the phantom comprising at least one first region having at least one tissue like property and at least a first cavity having a plurality of hollow branches connected thereto, with at least some of the plurality of hollow branches being formed within the at least one region having tissue like properties, wherein the plurality of branches connected to the first cavity have an average root mean square error of less than 2 mm, and the phantom having both an anatomically correct outer shape and an anatomically correct inner shape.
