Scattered photons degrade nuclear medicine image contrast and resolution, and preclude simple attenuation corrections. Current scatter correction methods utilize detected events with energies below pulse height analyzer (PHA) window levels, making attenuation corrections source position dependent. This new scatter rejection technique analyzes only the(More)
Recorded sound often sounds dry and flat. A reverberator adds the impression of ambience to an acoustic signal that was recorded in a " dry " environment – the ultimate goal is to simulate a room's natural reverb. This paper presents basic acoustic theory as well as an implementation of Moorer's reverberator. Additionally, a hybrid algorithmic reverberator(More)
