The present invention relates to an apparatus for the detection of opacities in X-ray images. It is described to provide (210) an analysis X-ray image of a region of interest of an analyzed body part. A model of a normal region of interest is provided (220), wherein the model is based on a plurality of X-ray images of the region of interest. At least one abnormality is detected (230) in the region of interest of the analyzed body part, the detection comprising comparing the analysis X-ray image of the region of interest and the model of the normal region of interest. Information is output (240) on the at least one abnormality.

A radiographic apparatus includes: a hardware processor which generates image data of a radiographic image upon reception of external radiation, is capable of storing the generated image data in a storage, is capable of communicating with an external device via a communication unit, is capable of operating itself in a normal imaging mode or a memory imaging mode, and is capable of concurrently determining for a plurality of types of predetermined conditions whether each condition is satisfied. The hardware processor switches from the normal imaging mode to the memory imaging mode based on occurrence of the determination that at least one of a plurality of first predetermined conditions is satisfied in the normal imaging mode.

A computed tomographic (CT) apparatus and for a method of controlling the same are provided. The CT apparatus includes an X-ray scanner configured to divide X-rays penetrating a subject by energy bands, and capture scout images of the respective energy bands. The CT apparatus further includes an image processor configured to generate substance images of substances of the subject, based on the scout images, and a display configured to display a substance image of the substance images. The CT apparatus further includes an input interface configured to receive a scanning region for the displayed substance image.

Various embodiments of a device for in-vivo measurements radiopharmaceuticals used for diagnosis and monitoring of radiotherapy are presented. In some embodiments, the present disclosure relates to a device having a cannula that may include a measurement chamber, a radiation detector and a delivery lumen, wherein the device may be used to both deliver material to the patient (e.g., radiotracers used in radiopharmaceuticals) and measure levels and concentrations of radioactive material in, for example, the patient's blood both during and after administration of the radioactive material. In some embodiments, a plunger may be utilized to draw blood through a first opening into the measurement chamber and then return it to the bloodstream. In some embodiments, particle absorbing materials may be used to limit measurements to materials within the measurement chamber or other area of interest.

When a first-stage push-button switch of an operation unit (2) is pressed, an X-ray imaging control unit (72) transmits a signal A for starting voice guidance to a signal output unit (73) for a voice guidance unit as well as a signal B for starting preparation of X-ray imaging to an X-ray tube control unit (71). At this time, when the pushing operation of the push-button switch is performed, the X-ray imaging control unit (72) immediately transmits the signal A for starting the voice guidance to the signal output unit (73) for the voice guidance unit but transmits the signal B for starting the X-ray imaging after a time t1 has elapsed. The time t1 is a time calculated by subtracting a time t3 required for preparing an X-ray tube (42) for performing X-ray imaging from a time t2 required for the voice guidance.

A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry detects three or more bones and a joint space region from three-dimensional medical image data captured for images of a joint formed between the three or more bones, the joint space region corresponding to a joint space of the joint. The processing circuitry divides the joint space region into a plurality of small regions corresponding to different pairs of opposed bones of the three or more bones. The processing circuitry obtains information on each of the small regions based on the small regions into which the joint space region has been divided that correspond to the different pairs of bones. The processing circuitry outputs the obtained information.

Systems and methods are disclosed for evaluating a patient with vascular disease. One method includes receiving one or more vascular models associated with either the patient or with a plurality of individuals; receiving observed perfusion information associated with the patient; and estimating, using one or more computer processors, one or more blood flow characteristics or one or more pathological characteristics of the patient based on the observed perfusion information and the one or more vascular models.

A radiation imaging apparatus, comprising a radiation source configured to generate radiation, an image capturing unit configured to perform image capturing by detecting the radiation, and a processing unit configured to be communicable with the image capturing unit, wherein the processing unit performs a first operation which evaluates response time in communication with the image capturing unit, and a second operation which sets a control timing of the radiation source based on an evaluation result of the response time obtained in the first operation.
