i got black image when opening dicom file in matlab
my code for opening dicom files
[real_image,real_path] = uigetfile( ...
{'*.*;','File Dicom (*.dcm)';},...
'Open Image');
if ~isequal(real_image,0)
handles.image = dicomread(fullfile(real_path,real_image));
guidata(hObject,handles);
axes(handles.axes1);
imshow(handles.image);
set(handles.text5,'String',real_image);
set(handles.text6,'String',real_path);
[row,column]=size(handles.image);
set(handles.text7,'String',row);
set(handles.text8,'String',column);
else
return;
end
I've tested your code by creating a GUI (R2012b) and inserting the code in pushbutton callback and it works fine.
So I can see two possibilities:
- the dcom image you are loading in somehow corrupted
- the dcom image is good and it is a probelm of contrast
I'll go for the second possibility.
I've used, as examples, the dcom images "CARDIX" downloaded from DICOM sample image sets.
As one of these images is loaded, it appears to be black and the axes's clim is [0 65535].
If you set the clim range to, respectively, the minimum and maximum values of the dcom image data value, you can start "seeing something".
To further enhance the visibility of the image you can use the imcontrast tool.
In the following you can find the .m file of the GUI: the imcontrast tool can be run through a pushbutton.

In the following picture you can see:
- the "black" image as it appears as loaded
- the first enhacement following the updating of the clim range
- the enhancements obtained "working" with the imcontrast tool
Notice: you can download a DCOMViewer from MATLAB Central.
Hope this helps.

I want to create a gui in matlab with a push button and a panel.
Requirements: Upon clicking the button the dialogue must open to choose a file and after selecting image from this dialogue the image must be shown to that panel of gui.
How do I do this?
How to show the image on the gui panel?
My current status so far:
function pushbutton1_Callback(hObject, eventdata, handles)
[filename, pathname] = ...
uigetfile({'*.jpg';'*.png';'*.jpeg';'*.bmp';'*.*'},'File Selector');
set(handles.axes2, 'Visible','on');
imshow(IMG,'Parent',TheAxisHandleToDrawOn)
if isequal(filename,0)
disp('Image upload Canceled')
end
I tried this but it's not working, how to do this?
With respect to your callback you have first to read the selected image by using imread; you can use fullfile to build the complete filename.
Then you use the matrix returned by imread as input for the imshow function.
Edit following the comments
In order to show the image within a uipanel you have to add an axes in the panel and use it as parent in the call to imshow.
If the image you want to display is not in the current folder or in a folder on the MATLAB path, you have to specify the full path name (ref. imread).
In the following you can find the .m file of the GUI I've build for test.
The GUI contains:
an axes (tag: axes2)
a uipanel (tag: uipanel1)
an axes (tag: axes_up) embedded in the uipanel
two radiobuttons (tag: radiobutton1 and radiobutton2) to select the axes on which to show the image
two statictext fields (tag: text2 and text3) to show the filename of the selected images
a pushbutton (tag: pushbutton1) to select the image to be displayed
a pushbutton (tag: pushbutton3) to run the imcontrast tool in case of selection of a .dcm image
The code has been tested on R2012b and 2015b.

plz help me solve this problem
how can i make A1:B2 to A2:B2 and A3:B3 by using 'for function'?
To fix this, you would have to create a matching string:
['A' num2str(i) ':B' num2str(i)]
For performance reasons, I recommend to read all three lines outside the loop in one call of xlsread.
for k=1:1:4
[~,~,raw] = xlsread('data.xlsx','data1');
popup_sel_index = get(handles.popupmenu1, 'Value');
switch popup_sel_index
case k
xlRange = sprintf('E%d:CW%d',k,k);
x1 = [0.25:0.25:24]
xlRange
y1 = xlsread('data.xlsx','data1',xlRange);
plot(x1,y1)

I just want to make a simple table like Excel in MATLAB GUI. Please see attached fig:

How can I add header parameters?
How can I change property of column 'sum'= unit*value?
How can I change property of column 'Result'=sum ' sum' column / EDOC?

A matlab component called uitable will be your GUI object.
Editing the value interactively could be done in different ways, this has a complete example.
I am struggling with how the Matlab gui interface works.
I am not looking for an answer, only some more guidance of how to do this.
I am trying to convert a temperature in an edit box from F to C...so I think I need the equation to be in the push button.
I guess I am stuck on how to pass the number from the edit box to the push button to convert it, then how to pass it back, then display it.
Does this make any sense?
function varargout = ICA09A_TEMPFtoC(varargin)
% ICA09A_TEMPFTOC MATLAB code for ICA09A_TEMPFtoC.fig
% ICA09A_TEMPFTOC, by itself, creates a new ICA09A_TEMPFTOC or raises the existing
% singleton*.
%
% H = ICA09A_TEMPFTOC returns the handle to a new ICA09A_TEMPFTOC or the handle to
% the existing singleton*.
%
% ICA09A_TEMPFTOC('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in ICA09A_TEMPFTOC.M with the given input arguments.
%
% ICA09A_TEMPFTOC('Property','Value',...) creates a new ICA09A_TEMPFTOC or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before ICA09A_TEMPFtoC_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to ICA09A_TEMPFtoC_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

Is there anything I should do to make this more readable for anyone editing?
To get the temperature entered in the text edit box use:
tempF = get(handles.degF_et,'String');
This can be called from the push button function.
To change the string that is displayed there use:
set(handles.degF_et,'String','some string');
