Abstract

A catheter lab imaging apparatus for imaging a heart region of a patient positioned thereon. The apparatus includes a catheter lab table, an x-ray imager positioned about the table and including a transmitter and a receiver, the transmitter being pivotable relative to the table to image the patient along predetermined imaging axes, a catheter lab table pad for supporting the patient on the table. The pad includes a top radiolucent layer defining a top surface of the pad and bottom radiolucent layer defining a bottom surface of the pad, the bottom layer being joined to the top layer around the periphery thereof to define at least one sealed chamber for supporting the patient. The pad may further include at least one interior seam positioned within the chamber to limit separation between the top layer and the bottom layer, wherein each of the interior seams is positioned such that each of the predetermined imaging axes avoids intersection with all of the interior seams when a patient is positioned on the pad.

Claims

1. In a process for performing catheter lab imaging on the heart of a patient utilizing a catheter lab imaging apparatus comprising a catheter lab table, an x-ray transmitter, and an x-ray receiver, the improvement comprising the steps of:

positioning a pneumatic pad on the table, the pad including a radiolucent portion positioned in an imaging region of the table, and the pad further including seams;

inserting gas into the pad to at least partially inflate the pad;

positioning the patient in a reclined position on the pad such that the patient'"'"'s heart is aligned with the radiolucent portion of the pad;

imaging the heart of the patient while performing a catheter lab procedure, wherein the imaging apparatus images along predetermined imaging axes, wherein said positioning the pad step comprises positioning the seams to avoid interference with the imaging axes;

removing the patient from the pad; and

removing the gas from the pad to deflate the pad.

2. A method as claimed in claim 1, wherein the predetermined imaging axes extend through the patient'"'"'s heart at angles of 0°

, 30°

, 45°

, and 60°

relative to an axis extending perpendicular to the table.

3. A method as claimed in claim 1, wherein said inserting gas step occurs before said patient positioning step, and wherein said inserting gas step comprises filling the pad with gas to a pressure of less than about 1 psi.

4. A method as claimed in claim 3, wherein said pressure is about atmospheric pressure.

5. A method as claimed in claim 1, wherein said inserting gas step occurs before said patient positioning step, and wherein said inserting gas step comprises filling the pad with gas to less than maximum volume of the pad.

6. A method as claimed in claim 1, wherein said patient positioning step occurs before said inserting gas step, and wherein said inserting gas step comprises filling the pad with gas to less than about 2 psi.

7. In a process for performing catheter lab imaging on the heart of a patient utilizing a catheter lab imaging apparatus comprising a catheter lab table, an x-ray transmitter, and an x-ray receiver, the improvement comprising the steps of:

positioning a pneumatic pad on the table, with a radiolucent portion of the pad positioned in an imaging region of the table;

inserting gas into the pad to at least partially inflate the pad;

positioning a waterproof cover on the pad;

positioning the patient in a reclined position on the pad such that the patient'"'"'s heart is aligned with the radiolucent portion of the pad;

imaging the heart of the patient while performing a catheter lab procedure;

removing the patient from the pad; and

removing the gas from the pad to deflate the pad.

8. A method as claimed in claim 7, further comprising, after said removing patient step, the step of removing the waterproof cover from the pad.

9. A method as claimed in claim 7, wherein the cover includes an absorbent material secured thereto, and wherein said method further comprises the step of positioning the absorbent material under the upper leg and hip region of the patient.

10. A method as claimed in claim 9, wherein the absorbent material is detachably secured to the cover, and wherein the method further comprises the step of detaching the absorbent material from the cover.

11. A method as claimed in claim 7, wherein said waterproof cover is bag-shaped to substantially cover a top surface, a bottom surface and at least one end of the pad, and wherein said method further comprises, after said removing the waterproof cover step, the steps of:

turning the waterproof cover inside out; and

using the waterproof cover to contain waste produced during said imaging step.

12. In a process for performing catheter lab imaging on the heart of a patient utilizing a catheter lab imaging apparatus comprising a catheter lab table, an x-ray transmitter, and an x-ray receiver, the improvement comprising the steps of:

positioning a pneumatic pad on the table, with a radiolucent portion of the pad positioned in an imaging region of the table, wherein the pad comprises at least head and torso sections;

inserting gas into the pad to at least partially inflate the pad;

positioning the patient in a reclined position on the pad such that the patient'"'"'s heart is aligned with the radiolucent portion of the pad, wherein the patient is placed on the pad before the torso section is inflated and after the head section is inflated;

imaging the heart of the patient while performing a catheter lab procedure;

removing the patient from the pad; and

removing the gas from the pad to deflate the pad.
