Representative images from one participant during simultaneous emission-transmission dynamic SPECT imaging of radioaerosol deposition: 1. The transmission data is primarily used for attenuation correction of the emission data 2. The emission data records the deposition of the inhaled radioaerosol 3. The transmission data is also used to segment the three-dimensional margin of the lung fields in order to determine the regional distribution of the deposited radioaerosol within the lungs
