Abstract

A system for detecting lymphedema comprising a dual energy x-ray absorptiometry system and one or more spacer pads disposed within a field of view of the dual energy x-ray absorptiometry system. The dual energy x-ray absorptiometry system comprises an x-ray source and a patient support platform, wherein the patient support platform is configured to receive a patient in a supine position with the x-ray source disposed above the patient support platform. The one or more spacer pads are configured to be positioned between body parts of the patient.

First claim

What is claimed is:

1. A system for analyzing a body composition of a patient comprising:
a dual energy x-ray absorptiometry system comprising a computer, an x-ray source and a patient support platform, wherein the patient support platform is configured to receive the patient in a supine position and wherein the dual energy x-ray absorptiometry system is configured to scan the patient to measure the body composition; and
one or more spacer pads disposed within a field of view of the dual energy x-ray absorptiometry system, the one or more spacer pads configured to be positioned between body parts of the patient;
wherein the computer processes image information acquired with the dual energy x-ray absorptiometry system and detects the one or more spacer pads to provide an analysis of the body composition, such that the analysis of the body composition does not include information about the one or more spacer pads.

2. The system of claim 1 , wherein the one or more spacer pads comprises low x-ray attenuation material.

3. The system of claim 2 , wherein the low x-ray attenuation material is radiographic foam.

4. The system of claim 1 , wherein each of the one or more spacer pads is uniformly constructed.

5. The system of claim 1 further comprising a sanitary cover to cover each of the one or more spacer pads, the sanitary cover made of clear material.

6. The system of claim 1 , wherein a height of each of the one or more spacer pads exceeds a maximum body thickness of the patient.

7. The system of claim 1 , wherein the one or more spacer pads is rigid so that the one or more spacer pads does not flex during use.

8. The system of claim 1 , wherein the one or more spacer pads is positioned between at least one of an arm and torso of the patient and legs of the patient.

9. A method of analyzing a body composition of a patient comprising:
providing a dual energy x-ray absorptiometry system, the system comprising a computer, an x-ray source and a patient support platform;
positioning the patient in a supine position on the patient support platform;
positioning a spacer pad between body parts of the patient such that the spacer pad is positioned within a field of view of the dual energy x-ray absorptiometry system;
scanning the patient with the dual energy x-ray absorptiometry system to measure the body composition; and
computer processing image information acquired from the scanning step and detecting the spacer pad to provide an analysis of the body composition, such that the analysis of the body composition does not include information about the spacer pad.

10. The method of claim 9 further comprising scanning the patient using the dual energy x-ray absorptiometry system to detect lymphedema.

11. The method of claim 9 , wherein the spacer pad comprises low x-ray attenuation material.

12. The method of claim 11 , wherein the low x-ray attenuation material is radiographic foam.

13. The method of claim 9 , wherein the spacer pad is uniformly constructed.

14. The method of claim 9 , wherein the spacer pad is covered by a sanitary cover, the sanitary cover made of clear material.

15. The method of claim 9 , wherein a height of each of the one or more spacer pads exceeds a maximum body thickness of the patient.

16. The method of claim 9 , wherein the spacer pad is rigid so that the spacer pad does not flex during scanning.

17. The method of claim 9 , wherein the spacer pad is positioned between at least one of an arm and torso of the patient or legs of the patient.
