USER INTERFACE AND TECHNIQUE TO DISPLAY WAVEFORM AND ANALYSIS DATA FOR RESPIRATORY MOTION IMPACTED EMISSION TOMOGRAPHY

FIELD OF INVENTION

The invention generally relates to an emission tomography and more particularly to a display waveform and data analysis for respiratory motion impacted emission tomography.

BACKGROUND OF THE INVENTION

Generally, in a clinical imaging environment, efficient and automated display of time-sensitive information about a scan is important. For a complex imaging protocol, which includes acquisition of physiologic waveforms, such as, respiratory and cardiac signal, potential data to display is complex. As a result, a technologist is required to ‘dig around’ to acquire information about normal and/or typical waveform.

A conventional technique includes a principal components analysis (PCA)-based approach for respiratory waveform derived from positron emission tomography (PET) list mode.

Another conventional technique includes determination of the motion of an internal tissue or organ undergoing dynamic movement, such as, respiratory cycle.

Yet another conventional technique includes a non-transitory computer accessible medium with executable instruction capable of directing a processor. This allows generating a spatial-temporal maximum-intensity projection from a respiratory phase separated series of images.

However, the conventional technique does not navigate physiological waveform information from emission tomography.

 It would be desirable to have an efficient technique to navigate physiological waveform from emission tomography scan data.

DETAILED DESCRIPTION OF THE INVENTION

The present invention proposes a technique to describe automated display of data-derived physiologic trace information within resulting diagnostic image displays from an emission tomography. The technique includes an embodiment with a user interface, which enable automated display and navigation of physiologic waveform information. Waveform information is derived from the emission tomography scan data utilizing a principal components analysis technique. The demonstrative embodiment utilizes respiratory trace data derived from positron emission tomography (PET) coincidence events.

The technique includes steps to describe automated display of data-derived physiologic trace information. A first step includes acquiring emission tomography scan. A second step includes deriving physiologic waveform utilizing temporal nature of the data. An example waveform is that for respiration, which consists of the amplitude vs. time of a patient breathing. A third step includes viewing resu...
