A change in position over time for each of the at least partially overlapping axial positions is determined and a first respiratory waveform is estimated from the change in position over time for each of the at least partially overlapping axial positions.

Abstract: A novel PET calibration phantom structure is disclosed that has reduced overall weight and reduced radiation shielding requirement while still enabling safe handling. Furthermore, when the phantom is not being used, the ?+ radiation source can be turned off or removed from the phantom, thus, lowering the radiation exposure risk to those handling the phantom.

Abstract: A compact radar system for detecting displacement of an internal organ of a patient in a medical scanner. The system includes at least one transmitting antenna and at least one receiving antenna located in a bed arrangement that supports the patient. In particular, the receiving antenna is located a predetermined distance from a patient reference location to enable detection of electromagnetic energy reflected from a region of the internal organ undergoing asymmetric displacement. The system further includes a radar energizing system that energizes the transmitting and receiving antennas wherein the transmitting antenna irradiates a volume of the patient's body that includes the internal organ. In addition, the receiving antenna detects the reflected electromagnetic energy from the region of the internal organ undergoing asymmetric displacement to enable determination of inhalation and exhalation by the patient.
