Abstract
A microsphere delivery apparatus providing real-time measuring of delivered radioactivity during procedures utilizing radioactive emitting microspheres wherein an administration housing includes a holder to receive a vial containing microspheres for delivery from a housing, a detector holder to receive a radiation detector and a delivery tube assembly for transporting fluid containing the microspheres.
Claims60
A microsphere delivery apparatus for real-time measuring of radioactivity delivery to a patient, comprising:
- a delivery housing containing:
- a delivery apparatus configured to deliver radiation emitting particles along a delivery path from a container to a patient during radiation therapy;
- and
- a detector that detects radiation emitted by the particles to perform real-time monitoring of administered radioactivity delivered to the patient, the detector including:
- a radiation probe sized for positioning in a detector holder located at a distance from the container, and
- a memory connected to the radiation probe and configured to store a probe output in units of radioactivity.

A method for real-time measuring of radioactivity during radiation microsphere transport, comprising:
- measuring an initial reading of radioactivity in a microsphere source prior to beginning radiation emitting microsphere transport during with a radiation detector enclosed within a housing, the radiation detector being connected to an electronic display that displays an output in units of radioactivity, the housing including a fluid flow transfer path coupled to the microsphere source;
- recording the initial reading;
- and
- measuring an ending reading of radioactivity in the microsphere source after transport of radiation emitting microspheres from the housing along the fluid flow path.
