dcmcjpeg: Unable to change Planar Configuration Error

[martinrame]

Hi, a new equipment is sending images that I cannot convert to Jpeg Lossless.

With dcmcjpeg I get this error:

Code: Select all

E: True lossless encoder: Unable to change Planar Configuration from 'by plane' to 'by pixel' for encoding

It looks like the equipment is generating "non standard" images. Is there a way to try to fix those images?.

[Michael Onken]

Hi,

as far as I can see this error is only produced in case of serious problems, e.g. Planar Configuration is not present in the dataset, memory is exhausted or no pixel data is present.

Probably you should check the image with a DICOM validator, e.g. dciodvfy.

BR, Michael

Thanks Michael, this is the result of dciodvfy:

After a first look, I would remove Samples Per Pixel from the dataset, the value 2 is never used in any color model. Probably the machine "means" 1 (one color=grayscale channel) instead. Just remove Samples Per Pixel, e.g. by calling

Code: Select all

dcmodify -e SamplesPerPixel <input_file>

Just curious: There are many errors in the dataset, and it's in Big Endian, is this an old machine?

[martinrame]

Thanks, I removed SamplesPerPixel, but the viewer (Weasis) is still rejecting the image.

The equipment is new, but it uses a software to convert images to Dicom that maybe is old. I'm trying to contact the manufacturer, without too much expectations...

[martinrame]

BTW, dcmj2pnm is able to convert the image to jpg and I can view it correctly.

Hopefully I could modify the source file until I can display it in Weasis or Cornerstone.

[Michael Onken]

Mh, this is trial and error then. Invent values for Rescale Slope (1) and Intercept (0), if it does not help then maybe values for Window Center and Window Width, ... i.e. try fixing pixel related attributes that are reported by dciodvfy. Also, if dcmj2pnm prints warnings, fix those problems first.

Maybe Weasis does not support Big Endian? (dcmconv +te <input-file> <output-file> would convert to Little Endian Explicit).

[martinrame]

Fixed by adding SamplesPerPixel=1.

[Michael Onken]

Ah, of course, my mistake, of course Planar Configuration is not permitted if Samples Per Pixel = 1 but Samples per Pixel is required anyway Sry
