FFF.1.1 Time Relationships

FFF.1.1.1 Time Relationships of a Multi-frame Image

The following figure shows the time-related attributes of the acquisition of X-Ray multi-frame images. The image and frame time attributes are defined as absolute times, the duration of the entire image acquisition can be then calculated.

FFF.1.1.2 Time Relationships of one Frame

The following figure shows the time-related attributes of the acquisition of an individual frame “i” and the relationship with the X-Ray detector reading time and simultaneous ECG waveform acquisition.

Notes: 1. Positioner angle values, table position values etc… are measured at the Frame Reference Datetime.

2. Dose of the frame is the cumulative dose: PRE-FRAME + FRAME
