Abstract: Signal processing techniques that can include an embedded software low-noise response pulse detection, which can help provide an enhanced signal-to-noise characteristic, such as can help permit highly specific fast IR spectroscopic tissue analysis. Using a difference between (1) response signal values during a first time period duration of a response pulse from a tissue sample illuminated by illumination pulse, and (2) response signal values for a similar first time period duration between response pulses, for a low duty cycle (e.g., less than 50%, 10% or even at about 5% duty cycle) illumination pulse, accumulation of noise in the response signal between electromagnetic illumination pulses can be limited. In particular, the described signal pre-processing techniques can help extract meaningful information for performing spectroscopic analysis and characterization of the tissue sample despite amplitude and temporal variations that can be encountered when using the system.

Abstract: The present application provides an initial, or first, packed arc setup to be compared with predefined arc setup constraints. These predefined arc setup constraints constrain at least one or more of the number of patient table angles per target volume, the number of times the gantry moves along one arc per table angle, the sum of gantry span per metastasis over all arcs, and the minimum table span. Based on the result of the comparison between the first packed arc setup with the predefined arc setup constraints, a second arc setup is automatically suggested. The automatically suggested second arc setup may then be compared with the first arc setup by calculating a score for both setups. Several iterations of such a method can be carried out based on the comparison between an arc setup and the following, subsequent arc setup in the iteration.
