Abstract

A non-invasive visual imaging system is provided, wherein the imaging system procures an image of a transducer position during diagnostic or therapeutic treatment. In addition, the system suitably provides for the transducer to capture patient information, such as acoustic, temperature, or ultrasonic images. For example, an ultrasonic image captured by the transducer can be correlated, fused or otherwise combined with the corresponding positional transducer image, such that the corresponding images represent not only the location of the transducer with respect to the patient, but also the ultrasonic image of the region of interest being scanned. Further, a system is provided wherein the information relating to the transducer position on a single patient may be used to capture similar imaging planes on the same patient, or with subsequent patients. Moreover, the imaging information can be effectively utilized as a training tool for medical practitioners.

Claims

1. A non-invasive treatment and imaging system comprising:

a hand-held probe assembly comprising a transducer operable to obtain patient information and to provide treatment to a patient, the hand-held probe assembly comprising an external surface;

an imaging device attached to the hand-held probe assembly to track movement of the transducer, the imaging device operable to capture positional and/or orientation information of the transducer with respect to a surface on the patient;

a rigid member attaching the imaging device to the external surface of the hand-held probe assembly, the rigid member configured to position the imaging device at a fixed distance from the transducer during the capturing of the positional and/or orientation information of the transducer; and

a control system in communication with the transducer and the imaging device, the control system configured to receive corresponding patient information and positional and/or orientation information of the transducer, the control system further configured to correlate, fuse, and/or combine the corresponding patient information and positional and/or orientation information of the transducer.

2. The non-invasive treatment and imaging system of claim 1, the external surface of the probe assembly further comprising a positioning indicator.

3. The non-invasive treatment and imaging system of claim 1, wherein the imaging device is a visual imaging device.

4. The non-invasive treatment and imaging system of claim 3, wherein the visual imaging device is a video camera.

5. The non-invasive treatment and imaging system of claim 1, wherein the transducer is an ultrasound transducer.

6. The non-invasive treatment and imaging system of claim 1, wherein the transducer is a combined ultrasound imaging, therapy, and temperature monitoring transducer.

7. The non-invasive treatment and imaging system of claim 5, wherein the patient information is an ultrasound image.

8. The non-invasive treatment and imaging system of claim 1, the external surface of the hand-held probe assembly comprising a series of marks.

9. The non-invasive treatment and imaging system of claim 8, wherein the series of marks facilitates scaling of images by the control system, the images acquired by the imaging device during changes in position of the transducer.

10. The non-invasive treatment and imaging system of claim 8, wherein the series of marks comprises triangulation marks.

11. The non-invasive treatment and imaging system of claim 1, the external surface of the handheld probe assembly comprising an electromagnetic device.

12. The non-invasive treatment and imaging system of claim 11, wherein the electromagnetic device facilitates scaling of images by the control system, the images acquired by the imaging device during changes in position of the transducer.

13. The non-invasive treatment and imaging system of claim 1, the handheld probe assembly comprising an accelerometer.

14. The non-invasive treatment and imaging system of claim 13, wherein the accelerometer facilitates scaling of images by the control system, the images acquired by the imaging device during changes in position of the transducer.
