Abstract:
Disclosed are systems, devices and methodologies relating to proton computed tomography. In some implementations, detection of protons can yield track information before and after an object for each proton so as to allow determination of a likely path of each proton within the object. Further, measurement of energy loss experienced by each proton allows determination that a given likely path results in a given energy loss. A collection of such data allows characterization of the object. In the context of energy loss, such a characterization can include an image map of relative stopping power of the object. Various reconstruction methodologies for obtaining such an image, including but not limited to superiorization of a merit function such as total variation, are disclosed. In some implementations, various forms of total variation superiorization methodology can yield excellent results while being computationally efficient and with reduced computing time.

Abstract:
According to the improved systems and methods described herein, a patient may be immobilized so that one or both breasts are returned to a known position. Additionally, the improved systems and methods reduce respiratory movement of the breasts. Thus, the immobilization devices and techniques described herein provide accurate and reproducible breast positioning while simultaneously reducing respiratory motion.

Abstract:
A laser head (1200) is adapted to irradiate an interaction region of an inhabitable structure with laser light to remove material from the structure. The laser head (1200) includes a housing (1230) and a connector (1210) coupled to the housing (1230) and optically coupled to a laser generator. The connector (1210) is adapted to transmit laser light from the laser generator. The laser head (1200) further includes a first optical element (1235) and a second optical element (1235') contained in the housing (1230). The second optical element (1235') is optically coupled to the first optical element (1235). The laser head (1200) further includes a containment plenum (240) coupled to the housing (1200). The containment plenum (240) is optically coupled to the second optical element (1235') to receive the laser light from the second optical element (1235'). The containment plenum (240) is adapted to confine the material and to remove the material from the interaction region resulting from irradiating the structure with the laser light.

The input slit (631) has a width selected to provide sufficient light transmittance and sufficient resolution. The spectrometer (630) further includes an optical grating (632) adapted to receive light from the input slit (631) and to separate the light into a spectrum of wavelengths. The spectrometer (630) further includes a collection lens (633) adapted to receive a selected range of wavelengths of the separated light from the optical grating (632). The spectrometer (630) further includes a light sensor (634) adapted to receive the selected range of wavelengths and to generate a signal corresponding to an intensity of the received light.
