Abstract: A method for determining the position of a patient's organ with respect to at least two imaging devices includes a step of making at least one three-dimensional first image of an organ of a patient giving a first coordinate system and of a surface of the organ or skin region using a first imaging device without fixing any mark to the patient, placing the patient in an operation site having a second coordinate system and determining a first position of a second imaging device with respect to the second coordinate system of the operation site. In addition, the method includes the steps of making a second image with the second imaging device, matching the first and second images and providing a third device having a third coordinate system. The third device is positioned with respect to the second image of the second device which thereby positions the third device with respect to the first image of the first imaging device.

Abstract: A trash can transporter for use with a vertical support post that is fixed in the ground or to a base and that is provided with a lower can brace against which a lower portion of a trash can is received when the trash can is mounted on the post. Mounted on the uppermost end of the post is a handle support having a flange over which a handle of the can is received when the can is mounted on the post. The transporter permits easy removal of the trash can from the post and is formed with a central column having a pair of can braces mounted thereon in spaced relation for supporting the can during the transporting movement thereof, a handle bracket being joined to the column adjacent to the upper end thereof and receiving the handle of the trash can when the trash can is removed from the vertical post for the transporting thereof.
