    • A method and system for converting low-dose mammographic images with much noise into higher quality, less noise, higher-dose-like mammographic images, using of a trainable nonlinear regression (TNR) model with a patch-input-pixel-output scheme, which can be called a call pixel-based TNR (PTNR). An image patch is extracted from an input mammogram acquired at a reduced x-ray radiation dose (lower-dose), and pixel values in the patch are entered into the PTNR as input. The output of the PTNR is a single pixel that corresponds to a center pixel of the input image patch. The PTNR is trained with matched pairs of mammograms, inputting low-dose mammograms together with corresponding desired standard x-ray radiation dose mammograms (higher-dose), which are ideal images for the output images. Through the training, the PTNR learns to convert low-dose mammograms to high-dose-like mammograms. Once trained, the trained PTNR does not require the higher-dose mammograms anymore. When a new reduced x-ray radiation dose (low dose) mammogram is entered, the trained PTNR would output a pixel value similar to its desired pixel value, in other words, it would output high-dose-like mammograms or “virtual high-dose” mammograms where noise and artifacts due to low radiation dose are substantially reduced, i.e., a higher image quality. With the “virtual high-dose” mammograms, the detectability of lesions and clinically important findings such as masses and microcalcifications can be improved.
    • 一种使用具有贴片输入像素输出方案的可训练非线性回归(TNR)模型将具有大量噪声的低剂量乳房X线照相图像转换为更高质量,更少噪声,更高剂量的乳房X线照相图像的方法和系统, 这可以称为基于呼叫像素的TNR(PTNR)。 从以减少的X射线辐射剂量(较低剂量)获取的输入乳房X线照片提取图像贴片,并且补片中的像素值作为输入输入到PTNR中。 PTNR的输出是对应于输入图像块的中心像素的单个像素。 PTNR训练有匹配的乳房X线照片,输入低剂量乳房X线照片和相应的所需标准x射线辐射剂量乳房X线照片(较高剂量),这是输出图像的理想图像。 通过培训,PTNR学习将低剂量乳腺X线照片转换为高剂量乳腺X线照片。 训练有素的PTNR不再需要较高剂量的乳房X线照片。 当输入新的减少的X射线辐射剂量(低剂量)乳腺X线照片时,经训练的PTNR将输出与其所需像素值相似的像素值,换句话说,它将输出高剂量的乳房X线照片或“ 剂量“乳房X线照片,其中由于低辐射剂量引起的噪声和伪影显着减少,即更高的图像质量。 通过“虚拟大剂量”乳腺X线照片,可以改善病灶的可检测性和临床重要发现,如肿块和微钙化。

    • A radio transmission apparatus does not update the distortion compensation coefficient for a certain period, which is shorter than the transmission period, after the transmission period start timing. Instead, update operation of the distortion compensation coefficient is carried out after the lapse of a certain period from the start timing. Further, in order to shorten the convergence time of the distortion compensation coefficient, the radio transmission apparatus performs interpolation processing of the distortion compensation coefficient. The distortion compensation coefficient is given to a two-dimensional coordinate (address): one is the power level of an input transmission signal and the other is the difference of power between the input transmission signal and a feedback signal. The distortion compensation coefficient at a predetermined coordinate is updated to an interpolated value, which is obtained through interpolation calculation using the distortion compensation coefficient at a coordinate adjacent to the predetermined coordinate.
    • 在发送周期开始定时之后,无线发送装置不更新比发送期间短的一定期间的失真补偿系数。 相反,在从开始定时经过一段时间之后,执行失真补偿系数的更新操作。 此外,为了缩短失真补偿系数的收敛时间,无线发送装置进行失真补偿系数的内插处理。 失真补偿系数被赋予二维坐标(地址):一个是输入传输信号的功率电平,另一个是输入传输信号与反馈信号之间的功率差。 将预定坐标处的失真补偿系数更新为通过使用与预定坐标相邻的坐标处的失真补偿系数的内插计算而获得的内插值。
