Cabinet structure configurations for infusion systems

A cabinet structure comprising:

• a platform on which a system configured to generate and infuse radiopharmaceuticals is mounted, the system comprising a shielding assembly providing a barrier to radioactive radiation that includes a first compartment configured to receive a waste bottle, and a second compartment configured to receive a radioisotope generator;
• and
• a shell surrounding the shielding assembly of the system, the shell including a first upper opening, a second upper opening, and an access panel,
• wherein the first upper opening is located at a first elevation, with respect to a lowermost portion of the cabinet structure, and is configured to provide access to the first compartment of the shielding assembly,
• wherein the second upper opening is located at a second elevation, with respect to the lowermost portion of the cabinet structure, the second elevation being lower than the first elevation, and the second upper opening being configured to provide access to the second compartment of the shielding assembly so that a person can lower the radioisotope generator through the second upper opening and into the second compartment, and lift the radioisotope generator out from the second upper opening;
• and
• wherein the access panel mates with the second upper opening and is removable therefrom.
