  • Patent number: 11189456
    Abstract: A sample may be inspected by making particles traverse the sample. The particles that have traversed the sample hit a detector one-by-one. In response thereto, the detector provides a sequence of respective detection outputs. The sequence of respective detection outputs is processed so as to identify respective locations where respective incident particles have hit the detector. An image is generated on the basis of the respective locations that have been identified. In order to determine a location where an incident particle has hit the detector, an evaluation is made with regard to pre-established respective associations between, on the one hand, respective locations where incident particles have hit the detector and, on the other hand, respective detection outputs.

  • Patent number: 10942137
    Abstract: An X-ray imaging system for reconstructing X-ray spectra includes an integrating detector and a measurement mask, including at least one physical filter, positioned between the integrating detector and an X-ray source spectrum. The integrating detector receives a masked X-ray spectrum after the source spectrum has been filtered in accordance with the measurement mask. As a result of the measurement mask containing one or more physical filters being combined, a measurement mask having energy band-pass regions can be generated, to cover the source spectrum. Measured data, based on the masked X-ray spectrum and characteristics of the measurement mask, is collected from the integrating detector. The X-ray imaging system reconstructs an X-ray spectrum and generates the reconstructed X-ray spectrum based on applying a predetermined algorithm, such as total variation minimization reconstruction, to the measured data.

  • Patent number: 10918349
    Abstract: In a first scenario, a third switch is opened when a first switch is opened to turn off the power supply provided to a device main body and a second switch is short-circuited. The third switch is opened as a result of the power supply provided to the main body controller being stopped. In a second scenario, the third switch is opened when the device main body is in a running state, the first and second switches are short-circuited, when a trolley is moved between hospital rooms. Whether or not the device main body is in a running state is recognized as a result of a lock unit sending a signal to the main body controller, said signal indicating that an arm has come in contact with the lock unit and the arm is arranged at a fixed position where the arm should be arranged when moving the trolley.

    Abstract: A method for radiation therapy treatment verification includes, acquiring treatment plan information from a radiation therapy system, patient image data, and transit image data received from an electronic portal imaging device during radiation therapy. The treatment plan information is divided into a plurality of segments. Predicted segment image data is determined utilizing a predicted image calculation algorithm and at least the patient image data and the treatment plan information. A predicted integrated image is determined through superposition of the predicted segment image data. Measured segment responses are determined from the transit image data utilizing the predicted segment image data and the predicted integrated image. The measured segment responses are converted to measured segment doses. A measured dose map having a sum of the measured segment doses is compared to a planned dose map based on the treatment plan information to assess radiation treatment delivery.
