Fig. 3From: ParaPET: non-invasive deep learning method for direct parametric brain PET reconstruction using histoimagesTraining the LSTM using simulated tissue activity curves (TAC) and the AIF (Cp) as input (step e in Fig. 1). TAC and Cp undergo deconvolution using a 1D transposed convolution layer (a). Two layers (LSTM 1 and 2) with a fully connected layer (b) was trained against simulated training labelsBack to article page
