Ultrasound phantoms
First Claim
1. An ultrasound phantom for use with an ultrasound scanner, comprising:
- (a) a container having a bottom and walls, margins of the walls defining a window;
(b) an ultrasound-transmitting window cover sealed to the margins defining the window to close the window, the window cover comprising a multi-layer film formed of at least a layer of metal adhered to a layer of plastic; and
(c) a phantom body contained within the container comprising a water based tissue mimicking material.

Abstract
An improved ultrasound phantom includes a container having a window covered by an ultrasound transmitting window cover that seals and protects a water based tissue mimicking material within the container. The window cover includes a multi-layer film formed of at least a layer of metal adhered to a layer of plastic. The metal layer is essentially impervious to moisture and air molecules, preventing both desiccation of the water based material within the phantom and oxidation or contamination of the tissue mimicking material. Multiple windows may be formed in the container which are closed with the multi-layer film cover, and the container may be formed entirely or partially as a flexible sack of multi-layer film.
