Description

Image management system and computer program products

The invention relates to a system for managing the internal image data of an object. The internal image data of the object is obtained by using an X-ray fluoroscopy device or a CT (Computed Tomography, computer tomography) scanning device, PET (Positron Emission Tomography (positron radiography) device and other imaging devices are obtained by photographing the object.

Previously, in the medical field, various imaging devices such as X-ray fluoroscopy devices, CT scanning devices, PET devices, and MRI (Magnetic Resonance Imaging) devices (hereinafter also referred to as "medical imaging devices") were obtained The image of the subject's body is used to diagnose the presence or absence of the disease based on the location, shape, and size of the lesion reflected in the image. For example, in the CT scanner, the subject is placed between the X-ray generator and the X-ray detector that are oppositely arranged, and while the X-ray generator and the X-ray detector are rotated around the subject, a The subject is irradiated with X-rays, and the intensity of X-rays transmitted through the subject's body is detected. The X-ray transmission rate differs according to the organs, so the X-ray transmission surface can be obtained according to the intensity of the X-rays passing through the subject’s body, that is, the image of the sliced surface (circumferential image) obtained by circumcising the human body ).

The greater the intensity of the X-rays irradiated to the subject, the more vivid the in-vivo images obtained by the CT scanning device, but from the viewpoint of safety, it is usually based on the image quality that can be used to obtain a diagnosis of disease There is a sufficient way to set the intensity of the X-rays irradiated to the subject. In order to generate X-rays of the required intensity, it is necessary to properly set parameters such as the value of the power supplied to the X-ray generator or the size of the aperture.

Patent Document 1 discloses a management system including a storage means that combines data of an image of a subject's body captured by a medical imaging device such as a CT scanning device and imaging conditions (X-ray generator and X The setting of the parameters of the ray detector, etc.) and the X-ray amount data at the time of photography are stored together, and the website or an external terminal can be used to browse the images stored in the storage means, and the shooting conditions and shooting time corresponding to the images X-ray volume information. In the management system of Patent Document 1, the image data of the highest quality obtained by the photographing device or the image data obtained by photographing the model for photography are stored in advance together with the data of the photographing conditions and X-ray amount In the storage means, this can be used for relative evaluation of the image quality of the photographic image of an object, or it can be used as a reference for setting parameters when using an imaging device to photograph the object.
