延迟相乘叠加求和 DMAS (Field II 仿真代码) （Delay Multiply and Sum, DMAS）算法，最初是为雷达微波系统设计的，研究者们对 DMAS 波束合成方法进行了修改，并应用超声成像。结果表明，DMAS 波束合成在模拟和实验中的表现都优于传统的延时叠加（Delay and Sum, DAS），这种新方法带来的主要改进是对比度分辨率明显提高（即主瓣和侧瓣更窄），从而增加了动态范围，提高了 B 型超声图像质量。与传统 DAS 相似，DMAS 算法通过对来自超声换能器阵元的信号应用几何计算延迟来聚焦接收到的波束。阅读详情

为什么静态控件不能显示Bitmap？
源程如下：

#include "stdafx.h"
#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
#include "resource.h"

char lpszClassName1[] = "static";
char lpszText[]="";
HWND hwndStatic ;
HINSTANCE hInst;
HBITMAP hBm;
BITMAP bm;

LRESULT CALLBACK WndProc( HWND hwnd, UINT message, WPARAM wparam, LPARAM lparam);

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
// TODO: Place code here.
HWND hWnd;
MSG Msg;
WNDCLASS WndClass;

char lpszClassName[] = "控件";
char lpszTitle[] = "静态控件";
WndClass.cbClsExtra = 0;
WndClass.cbWndExtra = 0;
WndClass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
WndClass.hCursor = LoadCursor(NULL, IDC_ARROW);
WndClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
WndClass.hInstance = hInstance;
WndClass.lpfnWndProc = WndProc;
WndClass.lpszClassName = lpszClassName;
WndClass.lpszMenuName = NULL;
WndClass.style = 0;

if(!RegisterClass(&WndClass))
{
MessageBeep(0);
return FALSE;
}

hWnd = CreateWindow(lpszClassName, lpszTitle, WS_OVERLAPPEDWINDOW, CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,NULL,NULL,hInstance,NULL);

hBm = LoadBitmap(hInst, MAKEINTRESOURCE(IDB_BITMAP));
GetObject(hBm, sizeof(BITMAP), (LPVOID)&bm);
sprintf(lpszText,"该位图高度为%d, 宽度为%d。",bm.bmHeight, bm.bmWidth);

ShowWindow(hWnd, nCmdShow);
UpdateWindow(hWnd);

hInst = hInstance;

while(GetMessage(&Msg,0,0,0))
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}

LRESULT CALLBACK WndProc( HWND hwnd, UINT message, WPARAM wparam, LPARAM lparam)
{
switch(message)
{
case WM_CHAR:
if (wparam == 27 )
PostQuitMessage(0);
break;
case WM_CREATE:
hwndStatic = CreateWindow(lpszClassName1,"IDB_BITMAP",
WS_BORDER|WS_CHILD|WS_VISIBLE|SS_BITMAP|SS_NOTIFY,
30,30,
0,0, // autosize
hwnd,
(HMENU)IDB_BITMAP,
hInst,
NULL);
break;
case WM_COMMAND:
switch(LOWORD(wparam))
{
case IDB_BITMAP:
break;
}
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
}
return DefWindowProc(hwnd, message, wparam, lparam);
}
