AAAAA.3.2.3 Photoacoustic/Ultrasound Coupled Acquisition Per-frame Example
In this encoding of the example shown in Figure AAAAA.3.2-1, the first frame of the image is shown for three images: one Photoacoustic image processed from one excitation wavelength, one Photoacoustic image processed from two excitation wavelengths, and one ultrasound image (Table AAAAA.3.2.3-1, Table AAAAA.3.2.3-2, Table AAAAA.3.2.3-3). For brevity, examples of other Photoacoustic attributes are provided in Section AAAAA.3.4.
