  • SYSTEMS AND METHODS FOR ADAPTIVE ENHANCEMENT OF VASCULAR IMAGING

    An ultrasound system (100) includes an ultrasound transducer, a processing circuit (210, 300), and a display. The ultrasound transducer is configured to detect ultrasound information regarding a patient and output the ultrasound information as an ultrasound data sample. The processing circuit (210, 300) is configured to segment the ultrasound data sample into a binary image including at least one first region and at least one second region, obtain a first location of a first vascular feature of the binary image based on a boundary between the at least one first region and the at least one second region, and modify the binary image based on the first location of the first vascular feature. The first vascular feature is associated with an intima media thickness.The display is configured to display the modified image.

  • SYSTEMS AND METHODS FOR TEMPORAL PERSISTENCE OF DOPPLER SPECTRUM

    An ultrasound system (100) includes an ultrasound transducer, a processing circuit (300), and a display. The ultrasound transducer is configured to detect ultrasound information from a patient (610) and output the ultrasound information as an ultrasound data sample (612), the ultrasound information representing blood flow of the patient. The processing circuit (300) is configure to determine a first characteristic of a first plurality of the ultrasound data samples (614) detected prior to a current ultrasound data sample, the first characteristic representing periodic features of the blood flow, determine a second characteristic of the current ultrasound data sample (616), compare the first characteristic to the second characteristic (618), modify the current ultrasound data sample based on the comparison (620), and output spectrum information (622) of the current ultrasound data sample modified based on the comparison of the first characteristic and the second characteristic. The display is configured to display the spectrum information (624).

  • Burned-Area Mapping at the Subpixel Scale With MODIS Images

    Ling, Feng   Du, Yun   Zhang, Yihang   Li, Xiaodong   Xiao, Fei  

    The Moderate Resolution Imaging Spectroradiometer (MODIS) is an important data set in global burned-area mapping. The MODIS global burned-area product has a coarse spatial resolution at approximately 500 m, which often introduces errors to the mapped burned areas. In this letter, a novel subpixel mapping (SPM) approach was proposed to produce burned-area maps at the fine spatial resolution similar to Landsat imagery, by exploring the spectral and spatial information provided by the second and fifth bands of MODIS. The proposed SPM approach aims to refine the estimate of burned areas, which have been detected by the MODIS global burned-area product. The performance of the proposed SPM approach was assessed with an experiment area containing six burned areas, by comparing with the MODIS burned-area product MCD45. The result shows that the average omission error decreased from 52.26% for MCD45 to 16.74% for SPM, and the average commission error decreased from 21.76% for MCD45 to 12.54% for SPM. The kappa value increased from 0.5583 for MCD45 to 0.8756 for SPM, indicating that the proposed SPM approach is effective in reducing the influence of the coarse spatial resolution of MODIS imagery in mapping a burned area and refining existing global burned-area products.

  • SYSTEMS AND METHODS FOR PULSED WAVE PREDICTIVE PROCESSING

    A system (100) includes an ultrasound transducer (234), a processing circuit (210), and a display (190). The ultrasound transducer (234) is configured to detect ultrasound information from a patient and output the ultrasound information. The ultrasound information represents blood flow of the patient. The processing circuit (210) is configured to generate a first waveform by automatically tracing the ultrasound information, identify a plurality of prior heart cycles of the first waveform and a current heart cycle of the first waveform, predict a second waveform based on the plurality of prior heart cycles, and update a visual representation of the current heart cycle based on the second waveform. The display (190) is configured to display the visual representation of the current heart cycle.

  • Analyses on the Pricing Factors from a Case Study of Light Trucks

    Ling, Feng   Ojima, Yoshikazu   Suzuki, Tomomichi  

    The purpose of this paper is to clarify analytically the relation between the characteristics and the pricing of the products of individual manufacturers, so we can offer beneficial information for designing and developing products. Light trucs of 1 ton to 4 ton have been taken up as examples. We carried out analyses based on the information on the evaluation of the functional characteristics by surveying the specifications obtained from light truck catalogues.
