Abstract: A therapeutic or diagnostic system comprises a non-invasive brain stimulation device (such as a TMS stimulation device) or other neuromodulation device configured to stimulate a patient's brain or nervous system by emitting electromagnetic pulses according to stimulation parameters, such as a pulse frequency or burst repetition frequency or other parameters, that provides surprising improvements in responsiveness and/or may require only a relatively short train of pulses to achieve high efficacy. In particular, stimulation pulses may be delivered at a frequency of between 12 and 40 Hertz with a 3 to 5 ratio as compared with burst repetition frequency, or at other specific patterns within that range. The stimulation parameters may be pre-stored and customized to individual patients, being identified through an automated search routine during which patient feedback is monitored. A user interface may be provided to allow an operator to conveniently select the appropriate parameters for the desired treatment.

Abstract: An exemplary method of treatment involves the non-invasive delivery of near infrared light (NIR) in 600-1200 nm wavelengths at surface wattage of 10.01-20.00 watts applied using a continuous motion technique. Treatment duration can be 30-1800 seconds, and can be conducted using a specific pulsed NIR technique for minimizing surface tissue heating. This is a novel process of non-invasive NIR/laser therapy. Prior applications used low levels of NIR therapy—most less than 1 watt with some up to 5 watts. Embodiments of the methodologies can be practiced with a laser unit having control for wavelength and for 1-20 watts. A Pulsed (on/off laser beam) control for 1-1000 milliseconds may also be utilized. An applicator with 1-2 cm aperture can be used to produce approximately 0.64-1.95 Joules per cm2 fluence in the depth of tissue. A display detailing watts, time, continuous or pulsing, and Joules of therapy is useful.

Abstract: The invention relates to an apparatus for determining a number of beams in IMRT. An objective function providing unit (13) provides an objective function of an IMRT procedure, wherein the objective function depends on a target dose to be applied during the IMRT procedure. A sensitivity determination unit (14) determines the sensitivity of the objective function with respect to changes of the target dose, and a beam number determination unit (15) determines the number of beams depending on the determined sensitivity. It has been found that the sensitivity of the objective function with respect to changes of the target dose is an accurate measure for reliably determining an optimized number of beams in IMRT, which allows for generating a high quality treatment plan and which in turn leads to an improved IMRT procedure.

Abstract: An irradiation apparatus radiates a particle beam after forming the beam for plural layers. A dose monitor measures a dose in real time. A dose evaluation unit evaluates an irradiation dose for each layer on the basis of a value measured by the dose monitor and a dose calibration factor set for each layer. An irradiation control section performs radiation control for each layer on the basis of an evaluation result of the dose evaluation unit. An interpolation value generation unit uses actual-measurement dose-calibration factors obtained by radiating a particle beam to a simulated phantom provided with a calibration dosimeter, to generate an interpolation estimation value of the dose calibration factor. For each layer subject to the interpolation value, and based on an irradiation condition of that layer, the interpolation value generation unit performs weighting on each of the actual-measurement dose-calibration factors.
