Volume data () constituted of more than one slice image () shot with a CT scanner () is transferred to an image server (). A CPU () of the image server () makes a site recognizing section () recognize a site of each slice image () included in the volume data (). The recognized site is recorded in a tag area () of each slice image () as site information (). The CPU () refers to the site information () of each slice image () and judges whether more than one site is included in the volume data () or not. When judging that more than one site is included in the volume data (), an image compression section () selects a common compression mode and compresses each slice image () under a common compression format and a common compression ratio.

Volume data formed of tomographic images (medical images) is stored in a storage unit of a data center. Recorded in a tag area of each tomographic image is site information indicating the site contained in each tomographic image. A data server of the data center reads the volume data from the storage unit in response to a transmission request from a medical facility. Then, the data server extracts from the volume data the tomographic images of the same site as designated by the transmission request. The data server transmits the extracted tomographic images to the medical facility which made the transmission request.

Image transmission method, image transmission apparatus, and image transmission program

A CT scanner pre-scans a patient by radiating rays of a lower amount from one direction to obtain a perspective prescanning image. An operator defines a main scanning area, in which images for medical application are to be captured, with reference to the prescanning image displayed on a monitor screen. A site recognizer analyzes data of the prescanning image to recognize anatomical structures located in the defined main scanning area. Based on the recognized anatomical structures and order data designating a site of inspection, it is judged whether the main scanning area corresponds to the site of inspection designated by the order data. If not, a warning is displayed on the monitor screen. The site recognizer may recognize all anatomical structures contained in the prescanning image, so that a default main scanning area may be defined on the basis of the recognition results and the order data.

Imaging method and modality for medical application

A normal structure element image representing normal structure of at least predetermined one of structure elements of an object images of which are included in an image of the object is artificially generated. A structure-removed image, which is an image obtained by removing the predetermined structure element from the image of the object, is generated by an image operation between the image of the object and the normal structure element image of the predetermined structure element.

When carrying out further color balance adjustment processing on color-balance adjusted image data having been through color balance adjustment processing, processing performance of the further color balance adjustment processing is sufficiently used. In a digital camera, by carrying out processing such as first AWB processing and chroma enhancement processing on original image data obtained by photographing, output image data are obtained. The output image data are then input to a printer. In the printer, processing which is the inverse of processing carried out in processing means of the digital camera and inverse AWB processing which is the inverse of the first AWB processing is carried out on the output image data, and inverse AWB image data which can be regarded as the original image data are obtained. Processed image data are then obtained by carrying out second AWB processing different from the first AWB processing on the inverse AWB image data, and a print is generated by output means based on the processed image data.
