The invention provides a medical image processing apparatus and a medical image processing method, which can reduce metal artifacts and maintain image quality in areas with small influence of the metal artifacts. A medical image processing apparatus includes a calculation unit that reconstructs a tomographic image from projection data of a subject including metal, and is characterized in that: the calculation unit acquires a machine learning output image that is output when the tomographic image is input into a machine learning engine that performs machine learning to reduce metal artifacts; the machine learning output image and the tomographic image are synthesized to generate a synthesized image. 本发明提供医用图像处理装置以及医用图像处理方法，减少金属伪影并且在金属伪影的影响小的区域也能够维持画质。一种医用图像处理装置，具备运算部，从包含金属的被检体的投影数据重构断层图像，其特征在于，所述运算部取得在对机器学习了减少金属伪影的机器学习引擎输入了所述断层图像时输出的机器学习输出图像，合成所述机器学习输出图像和所述断层图像，来生成合成图像。
