Image-assisted diagnostic evaluation
Disclosed herein is a framework for facilitating image-assisted diagnostic evaluation. In accordance with one aspect of the framework, imaging parameters used in acquiring a treatment image of a portion of patient anatomy are automatically recorded during an imaging examination. The treatment image may indicate at least one location of at least one treated site. During a follow-up examination, a follow-up image of the portion of the patient anatomy may be automatically acquired using the recorded imaging parameters. To assist evaluation of treatment results, the treatment image with the indicated location of the treated site may be overlaid over the follow-up image.
1. An imaging system for image-assisted diagnostic evaluation, comprising:
an acquisition processor configured to automatically record in a look-up table, during an imaging examination, at least one location of at least one treated site in association with imaging parameters used in acquiring a treatment image of a portion of patient anatomy, wherein the treatment image includes at least one marking indicating the at least one location of the at least one treated site, wherein the look-up table associates the imaging parameters with the treatment image and the location of the at least one treated site;
memory configured to store the look-up table and the treatment image; and
an image processor that configured to use, during a follow-up examination, the recorded imaging parameters in the look-up table to automatically acquire a follow-up image of the portion of the patient anatomy, set the treatment image to a predetermined transparency, overlay the treatment image with the marking over the follow-up image and compare the follow-up image with the treatment image to evaluate treatment results.
2. The system according to claim 1 , wherein the imaging parameters comprise at least one C-arm angulation indicative parameter.
3. The system according to claim 1 , wherein the imaging parameters comprise at least one patient support table position indicative parameter.
4. The system according to claim 1 , wherein the image processor is configured to, during the follow-up examination, adjust a C-arm and a patient support table according to the recorded imaging parameters to acquire the follow-up image.
5. The system according to claim 1 , wherein the treated site comprises a stem cell injection site.
6. The system according to claim 5 , wherein the patient anatomy comprises a heart and wherein the image processor compares the follow-up image with the treatment image by detecting any muscle movement at or near the treated site at the heart in the follow-up image.
7. The system according to claim 1 , further comprising:
a user interface for providing to a user the capability to mark the at least one location of the at least one treated site.
8. The system according to claim 1 , wherein the imaging examination occurs during treatment of a patient and the acquisition processor automatically terminates recording at the end of the treatment.
9. The system according to claim 1 , wherein the patient anatomy comprises a heart.
10. The system according to claim 1 , wherein the treatment image comprises a fluoroscopic image.
11. The system according to claim 1 , wherein the treatment image comprises an X-ray, magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), PET-CT, single-photon emission computed tomography (SPECT), SPECT-CT, MR-PET or ultrasound image.
12. The system according to claim 1 , wherein the follow-up image comprises a fluoroscopic image.
13. The system according to claim 1 , wherein the follow-up image comprises an X-ray, magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), PET-CT, single-photon emission computed tomography (SPECT), SPECT-CT, MR-PET or ultrasound image.
14. The system according to claim 1 , wherein the acquisition processor is configured to repeat, in response to a change in the imaging parameters, automatically recording the at least one location of the at least one treated site in association with the imaging parameters.
15. A method of supporting image-assisted diagnostic evaluation from a computer system, comprising:
automatically recording in a look-up table, during an imaging examination, at least one location of at least one treated site in association with imaging parameters used in acquiring a treatment image of a portion of patient anatomy, wherein the treatment image includes at least one marking indicating the at least one location of the at least one treated site, wherein the look-up table associates the imaging parameters with the treatment image and the location of the at least one treated site;
automatically associating the image parameters with the indication of the at least one location;
automatically acquiring, during a follow-up examination, a follow-up image of the portion of the patient anatomy using the recorded imaging parameters in the look-up table; and
evaluating treatment results by setting the treatment image to a predetermined transparency, overlaying the treatment image with the marking over the follow-up image, and comparing the follow-up image with the treatment image.
16. The method according to claim 15 , wherein the step of automatically recording the at least one location of the at least one treated site in association with the imaging parameters is repeated in response to a change in the imaging parameters.
17. The method according to claim 15 , wherein comparing the follow-up image with the treatment image comprises detecting any muscle movement at or near the treated site at the heart in the follow-up image.
18. The method according to claim 15 , wherein the imaging parameters comprise C-arm angulation and patient support table position indicative parameters.
19. The method according to claim 15 , wherein automatically acquiring the follow-up image comprises automatically adjusting a C-arm and a patient support table according to the recorded imaging parameters to acquire the follow-up image.
20. The method according to claim 15 , wherein the treated site comprises a stem cell injection site.
21. A non-transitory computer readable medium embodying a program of instructions executable by machine to perform steps for supporting image-assisted diagnostic evaluation, the steps comprising:
automatically recording in a look-up table, during an imaging examination, at least one location of at least one treated site in association with imaging parameters used in acquiring a treatment image of a portion of patient anatomy, wherein the treatment image includes at least one marking indicating the at least one location of the at least one treated site, wherein the look-up table associates the imaging parameters with the treatment image and the location of the at least one treated site;
automatically associating the imaging parameters with the indication of the at least one location;
automatically acquiring, during a follow-up examination, a follow-up image of the portion of the patient anatomy using the recorded imaging parameters in the look-up table; and
evaluating treatment results by setting the treatment image to a predetermined transparency, overlaying the treatment image with the marking over the follow-up image, and comparing the follow-up image with the treatment image.
