Abstract

Described is an in-scan phantom for use during an imaging procedure. The phantom can include at least one measuring insert and/or at least one measured insert. The measuring insert may have radiation detecting capabilities while the measured insert may include a radioactive material. Also described is an imaging modality system that includes an imaging modality and an in-scan phantom as well as methods of using the in-scan phantom for imaging a patient or performing a scout scan.

First claim

The invention claimed is:

1. An in-scan phantom for use during an imaging procedure of a patient, the in-scan phantom comprising:
at least one measured insert for measuring at least one property of the patient during the imaging procedure;
wherein the measured insert comprises a radioactive material.

2. The in-scan phantom of claim 1 , wherein the radioactive material is a positron emitter.

3. The in-scan phantom of claim 1 , wherein the measured insert comprising the radioactive material is of a shorter length than at least one other measured insert of the phantom.

4. The in-scan phantom of claim 1 , wherein the measured insert comprising the radioactive material is configured to move along a Z-axis of the phantom as the imaging procedure occurs.

5. The in-scan phantom of claim 1 , wherein the measured insert comprising the radioactive material comprises a pod containing the radioactive material, wherein the pod is configured to move along a Z-axis of the measured insert as the imaging procedure occurs.

6. The in-scan phantom of claim 1 , wherein the radioactive material is selected to represent an activity of a Standardized Uptake Value of approximately 1 in a nominal patient dose and weight.

7. The in-scan phantom of claim 1 , further comprising a second measured insert comprising at least one of a low density foam, an ultra-low density foam, and an X-ray active gas.

8. The in-scan phantom of claim 1 , further comprising a second measured insert comprising a water-filled tube.

9. An in-scan phantom for use in an imaging procedure of a patient, the in-scan phantom comprising:
a measured insert comprising a radioactive material for cross-correlation or quantification with an external standard or dose calibrator.

10. The in-scan phantom of claim 9 , wherein the measured insert comprising the radioactive material is configured to move along a Z-axis of the in-scan phantom as the imaging procedure occurs.
