### 8.2.8 Image Quality

The parameter name shall be "imageQuality" for URI mode. It is OPTIONAL for the URI mode. It shall not be present if contentType is application/dicom, except if the transferSyntax parameter is present and corresponds to a lossy compression.

If the requested media type is for a lossy compressed image (e.g., image/jpeg), this parameter indicates the required quality of the image to be returned within the range 1 to 100, 100 being the best quality.

The value shall be encoded as an integer string (IS), as specified in PS3.5.

### Note

Decompression and re-compression may degrade the image quality if the original image was already irreversibly compressed. In case the image has been already lossy compressed using the same format as required (e.g., jpeg), it may be sent as it is without decompressing and re-compressing it.

If the value of this parameter is less than 1 or greater than 100, then the response shall be a 400 (Bad Request), and may include a payload containing an appropriate error message.

### Note

The specific interpretation of the meaning of this parameter is left to the interpretation of the implementers of the standard.
