  • Patent number: 10228470
    Abstract: A method for real-time processing of a pulse pile-up event comprises the following steps of: generating a fitted baseline value lookup table and a fitted energy value lookup table for a pulse falling edge, using a multi-voltage threshold sampling method to identify piled-up pulses and trigger a procedure of processing pulse signals; and using pulse priori information and acquired pulse information to acquire information of an incorrectly sampled portion due to a pulse pile-up by looking up in the tables, so as to recover information of the pile-up pulses in real time. First, in the disclosure the multi-voltage threshold sampling method is proposed to identify pile-up pulses at a high count rate and trigger a procedure of processing pulse signals. Next, pulse priori information and acquired pulse information are used to acquire information of an incorrectly sampled portion due to a pulse pile-up by looking up in the tables, to recover information of the piled-up pulses in real time.

  • Patent number: 9532838
    Abstract: Methods and apparatus for enhancing surgical planning provide enhanced planning of entry port placement and/or robot position for laparoscopic, robotic, and other minimally invasive surgery. Various embodiments may be used in robotic surgery systems to identify advantageous entry ports for multiple robotic surgical tools into a patient to access a surgical site. Generally, data such as imaging data is processed and used to create a model of a surgical site, which can then be used to select advantageous entry port sites for two or more surgical tools based on multiple criteria. Advantageous robot positioning may also be determined, based on the entry port locations and other factors. Validation and simulation may then be provided to ensure feasibility of the selected port placements and/or robot positions. Such methods, apparatus, and systems may also be used in non-surgical contexts, such as for robotic port placement in munitions diffusion or hazardous waste handling.

The radiation detection system can also include a pulse analyzer that can determine whether the electrical pulse corresponds to a neutron-induced pulse, based on a ratio of an integral of a particular portion of the electrical pulse to an integral of a combination of a decay portion and a rise portion of the electrical pulse. Each of the integrals can be integrated over time. In a particular embodiment, the pulse analyzer can be configured to compare the ratio with a predetermined value and to identify the electrical pulse as a neutron-induced pulse when the ratio is at least the predetermined value.

  • Patent number: 9445774
    Abstract: An energy application apparatus applies energy to an object. The object (2), such as a tumor which has absorbed a radioisotope tracer, defines a location (3) of radioactive material. A location detection unit detects the location with the radioactive material. An x-ray unit applies x-rays to the detected location of the object. Since the location, to which energy should be applied, includes radioactive material, this location can be accurately detected by using the location detection unit. Moreover, since the application of the x-rays can be well controlled by controlling, for example, the intensity and the energy spectrum of the x-rays, energy can be accurately applied to the accurately detected location. The overall process of applying energy to the object can therefore be performed with increased accuracy.
