Question

我试图创建一个简单的DICOM查看器，在其中使用matplotlib绘制图像，并且希望在tkinter中显示相同的图（这是DICOM图像），但是在运行代码时出现此错误。请帮忙。当我尝试绘制a时会发生错误，但我认为它与声明x，y和p的值有关。

import pydicom
import matplotlib
matplotlib.use('TkAgg')
import numpy as np
from matplotlib.backends.backend_tkagg import 
FigureCanvasTkAgg
from matplotlib.figure import Figure
from tkinter import *
from pydicom.data import get_testdata_files

filename = get_testdata_files('000000.dcm')
dataset = pydicom.dcmread('000000.dcm')
data = dataset.pixel_array

class mclass:
  def __init__(self, window):
    self.window = window
    self.button=Button(window,text="check",command=self.plot)
    self.button.pack()

  def plot (self):
      if 'PixelData' in dataset:
          rows = int(dataset.Rows)
          cols = int(dataset.Columns)
      y=np.array(rows)
      x=np.array(cols)
      p=np.array(data)
      fig = Figure(figsize=(6,6))
      a = fig.add_subplot(111)
      a.plot(p, range(2+max(y)))

      canvas = FigureCanvasTkAgg(fig, master=self.window)
      canvas.get_tk_widget().pack()
      canvas.draw()

window = Tk()
start = mclass (window)
window.mainloop()

从它的外观看，您的错误就在这里：

    apply plugin: 'com.android.application'

android {
compileSdkVersion 28
defaultConfig {
    applicationId "com.example.mohammad.kahgle"
    minSdkVersion 21
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary = true

}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

}

您要求输入y=np.array(rows) ... a.plot(p, range(2+max(y)))，但是用于实例化max(y)和ds.Rows的{{1}}和ds.Columns是标量值（并且要确定的是您使用x）。这意味着y和int(ds.Rows)都将是一个0维数组，这将解释抛出的错误，大概是在x上。试试：

TypeError：使用numpy和pydicom在0维数组上进行迭代
