  • Patent number: 11931600
    Abstract: Techniques are presented for optimizing a treatment plan for charged particle therapy. The method includes obtaining medical image data voxels inside a subject in a reference frame of a radiation source that emits a beam of charged particles at multiple tracks with a controlled emitted energy at each track. Hydrogen density (HD) is determined based on the medical image data. Stopping power ratio (SPR) along a first beam having a first track and first emitted energy is calculated based on HD. A range to a Bragg peak is calculated along the first beam based on the SPR and the first emitted energy. The first beam track or the first emitted energy, or both, is modified based at least in part on the beam range to determine a second track and second emitted energy. Output data that indicates the second track and second emitted energy are sent.

  • Patent number: 11817098
    Abstract: Systems and methods for detecting demographic bias in automatic speech recognition (ASR) systems. Corpuses of transcriptions from different demographic groups are analyzed, where one of the groups is known to be susceptible to bias and another group is known not to be susceptible to bias. A difference between the transcription accuracy for the first group and a transcription accuracy for a second group is measured. ASR accuracy for each group is measured and compared to each other using both statistics-based and practicality-based methodologies to determine whether a given ASR system or model exhibits a meaningful level of bias. Based on the statistical significance and the practical significance, an alert including a recommendation to adjust the ASR model is generated.
