matlab dcm直方图

为了在Matlab中绘制DICOM图像的直方图，可以使用以下代码：

clc;
clear;

I_raw = dicomread('000000.dcm'); % 读取DICOM图像
I = double(I_raw); % 将灰度级映射到0~255
low = min(min(I)); % 计算最小灰度值
high = max(max(I)); % 计算最大灰度值
maxgray = high - low; % 计算窗宽
rate = 256 / maxgray; % 计算灰度级比例
I = I * rate; % 加窗处理
I = uint8(I); % 转化为8位位图数据格式

figure;
imhist(I); % 绘制原始DICOM图像的直方图
title('原始DICOM图像的直方图');

上述代码首先读取DICOM图像，并将其灰度级映射到0~255的范围。然后计算窗宽，并根据窗宽进行灰度级加窗处理。最后使用`imhist`函数绘制图像的直方图。将代码中的`'000000.dcm'`替换为实际的DICOM图像文件名即可。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
