Abstract: A travel controller of a vehicle that can travel on a road under autonomous driving control detecting two-wheelers, including bicycles, located in surroundings of the vehicle from surrounding data representing the surroundings of the vehicle generated by a surrounding sensor mounted on the vehicle, determining whether a target road on which the vehicle was traveling when the surrounding data in which a two-wheeler was detected was generated is a shared road on which travel by bicycles is permitted, when it is determined that the target road is a shared road, notifying a driver of the vehicle of a transition demand demanding transition in control of the vehicle from autonomous driving control to manual driving control requiring driving operations by the driver of the vehicle, and when it is determined that the target road is not a shared road, not notifying the driver of the transition demand.

Abstract: In a storing unit of a medical image processing apparatus, first 3D image corresponding to a first period and second 3D image data corresponding to a second period are stored. The first 3D image data corresponds to a period before contrast agent injection operation and/or therapeutic operation. The second 3D image data corresponds to a period after the contrast agent injection operation and/or therapeutic operation. A 3D subtracting unit subtracts the first 3D image data from the second 3D image data. In 3D subtraction image data, a portion having undergone a change due to contrast agent injection operation and/or therapeutic operation is emphasized. A pseudo 3D image data generating unit generates pseudo 3D image data on the basis of 3D subtraction image data. A displaying unit displays the pseudo 3D image data.

Abstract: When X -ray irradiation is performed with many X doses and the fall of temporary sensibility or the rise of the temporary offset arises, it is the X-ray diagnostic equipment which computes the correction by sensitiveness multiplier based on the sensibility characteristic or offset characteristic of each pixel, and rectifies data. In this X-ray diagnostic equipment, the correction by sensitiveness multiplier for data correction is determined based on the signal value detected last time at least. In integrating this correction by sensitiveness value from each pixel to the output signal, the influence by the fall of temporary sensibility or the rise of the temporary offset is removed.

Abstract: According to information input through a keyboard, an X-ray irradiation condition selecting portion selects an X-ray irradiation condition, retrieves a correspondence table according to this X-ray irradiation condition so as to read out a gain control state suitable for an irradiation condition, and drives an analog SW setting portion. According to a signal from the analog SW setting portion, an integration capacity of an initial stage integration amplifier is changed over. Further, according to other mode, accumulated electric charge Q of a picture element Cp is read out on a signal line and converted to a voltage Vo by the integration amplifier. By appropriately determining a sampling time by a sample/hold circuit after electric charge is read out, an influence of a switching element resistance can be excluded from a voltage Vx. Therefore, the voltage Vx can be sample held stably.

Abstract: The connections among a plurality of dynamic image generating means, a plurality of work stations, a plurality of temporary storage means and a plurality of video tape recorders are switched from one to another a matrix switcher, so that the number of the video tape recorders may be smaller than the total number of the dynamic image generating means and the work stations. The dynamic image generating means are connected via the temporary storage means to the video tape recorders, and the video tape recorders are connected via the temporary storage means to the work stations, so that wait time at the time of image recording or reproduction can be shortened.

Abstract: An X-ray diagnostic apparatus repeatedly radiates pulse-like X-rays, repeatedly images X-rays passing through an object to be examined at a predetermined frame period, and sequentially displays a plurality of images thus obtained repeatedly. In this invention, the exposure dose can be reduced since the number of X-ray irradiation times per unit time is set to be smaller than the number of frames to be imaged per unit time.

Abstract: A sawtooth wave forming circuit has an input signal alternately applied to the bases of first and a second transistors forming a differential amplifier, and a circuit which permits flow of a current equal to or proportional to the current flowing in the collector of the first transistor is connected between the differential amplifier and a power source. A capacitor is provided between ground and the junction between the circuit and differential amplifier. With this arrangement, the charge-discharge cycle of the capacitor is controlled by means of the input signal.By making use of the sawtooth wave forming circuit constituted in this way, stable trapezoidal or triangular waves having only small fluctuations in the slopes of the sides of the wave can be formed.
