struct Excitation f0: Center frequency [Hz] pulseduration: On-time / duration of the excitation pulse [s] dutycycle: [0, 1] total_duration: Total duration of waveform [s] fs: Sampling frequency of the received signal [Hz] end

struct Medium density: Density [kg/m³] c: Speed of sound [m/s] end

energy_spta(pressures::Array{Unitful.Pressure, N}, medium::Medium, excitation::Excitation)

Spatial Peak, Time Averaged energy [J/cm²]

getfdalimits(bodypart::String) Valid input string values are: "peripheralvessel", "cardiac", "fetal", "abdominal", "intraoperative", "pediatric", "small_organ", "cephalic", "ophthalmic".

Returns a named tuple with the fields: mechanicalindexlimit, sppalimit, sptalimit.

intensity(pressure::Unitful.Pressure, medium::Medium)

Instantaneous intensity [W/cm²]

pressure is expected to be a single number

intensity_sppa(pressures::Array{Unitful.Pressure, N}, medium::Medium, excitation::Excitation)

Spatial Peak, Pulse Averaged intensity [W/cm²]

pressures is expected to be an array with up to 4 dimensions. The first dimension is time, and the remaining dimensions are space
