From: Signal processing in urodynamics: towards high definition urethral pressure profilometry

Fig. 2

Signal flow in HD-UPP. Pressure data \(\varvec{p}\) are preprocessed through artifact elimination and a lowpass filter (LPF). Together with position and acceleration data a pressure image on the urethra’s inside is reconstructed and the urethral geometry in the sagittal plane calculated. The pressure image on the urethra’s outside is obtained through deconvolution and the results are mapped onto a 3D-representation of the urethra. User defined parameters control the algorithms’ behavior such as resolution of the pressure image
