Abstract: A disposable imaging phantom including a top housing having an inlet, and outlet, and first chamber in communication with the inlet and outlet and a bottom housing having a second chamber. The bottom housing connects to the top housing. The first 2024/030553 and second chamber are configured to receive a first fluid. The first chamber is configured to receive a second fluid through the inlet to displace the first fluid through the outlet. The imaging phantom also includes a membrane assembly configured to be positioned between portions of the top and bottom housings. The membrane assembly includes a semi-permeable membrane configured to permit diffusion of the second fluid from the first chamber into the second chamber.

Abstract: Disclosed herein is an injection device with housing that defines a channel and a first injection guide opening. The first injection guide opening enters the channel in a manner that allows a needle to penetrate a vessel in an animal with accuracy and at the same time protect the user from the needle.

Abstract: An imaging phantom having a housing and a dynamic perfusion assembly positioned within the housing. The dynamic perfusion assembly permits the flow of at least one contrast agent into a non-contrast solution at a desired rate. The dynamic perfusion assembly includes a first chamber that receives at least one contrast agent and a second chamber that receives a non-contrast solution. The second chamber receives the at least one contrast agent from the first chamber at the desired rate.
