  • Publication number: 20190086499
    Abstract: A magnetic resonance imaging apparatus according to the present embodiment includes processing circuitry and imaging control circuitry. The processing circuitry selects a human body model corresponding to a subject from human body models. The processing circuitry estimates local specific absorption rates (SARs) at evaluation points determined using the selected human body model, based on the selected human body model and an amplitude and/or phase of the RF pulse in an imaging protocol for magnetic resonance imaging scheduled to be performed on the subject. The processing circuitry determines whether or not the estimated local SARs fall below a local reference value. The imaging control circuitry executes the imaging protocol by using an amplitude and phase of the RF pulse which make the local SARs fall below the local reference value.

Based on the converted drawing data and on the non-converted drawing data, the processor creates PDL data to be output to an image forming apparatus.

  • Patent number: 10236971
    Abstract: To provide a technique capable of reducing the transmission delay of an image, a communication apparatus wirelessly communicable with another communication apparatus, receives a compressed captured image from the other communication apparatus; decompresses the compressed captured image to obtain a decompressed captured image; generates, based on the decompressed captured image, a CG image to be superimposed and displayed on the captured image; and compresses the CG image to generate a compressed CG image; transmits the compressed CG image to the other communication apparatus. Then, the communication apparatus derives a delay time based on a transmission time of the compressed captured image in the other communication apparatus and a generation completion time of the CG image; and changes a compression ratio of the CG image based on whether the delay time is longer than a predetermined threshold.
