摘要： A diagnostic imaging device includes a signal processing circuit (22) processes signals from a detector array (16) which detects radiation from an imaging region (20). The hit signals are indicative of a corresponding detector (18) being hit by a radiation photon. The signal processing circuit (22) includes a plurality of input channels (321, 322, 323, 324 ), each input channel receiving hit signals from a corresponding detector element (18) such that each input channel (321, 322, 323 , 324 ) corresponds to a location at which each hit signal is received. A plurality of integrators (42) integrate signals from the input channels (32) to determine an energy value associated with each radiation hit. A plurality of analog-to-digital converters (441, 442, 443, 44 4 ) convert the integrated energy value into a digital energy value. A plurality of time to digital converters (40) receive the hit signals and generate a digital time stamp. OR logic (36, 38) relays signal hits from a subset of the plurality of input channels (32) to one of the ADC (44) and one of the time to digital converters (40), the subset including more than one input channel such that more than one input channel is connected with each ADC (44) and/or each time-to-digital converter (40). A register and read out (25) reads out the locations, the digital energy values, and the digital time stamps for hit signals.

摘要： The invention relates to a radiation detector (100) that is particularly suited for energy resolved single X-rayphoton detection in a CT scanner. In a preferred embodiment, the detector (100) comprises an array of scintillator elements (S k ) in which incident X-ray photons (X) are converted into bursts of optical photons(hn). Pixels (P k ) associated to the scintillator elements (S k ) determine the numbers of optical photons they receive within predetermined acquisition intervals. These numbers can then be digitally processed to detect single X-rayphotons(X) and to determine their energy. The pixels may particularly be realized by avalanche photodiodes withassociated digitalelectronic circuits for data processing.

摘要： In nuclear imaging, solid state photo multipliers (48) are replacing traditional photomultiplier tubes. One current problem with solid state photomultipliers, is that they are difficult to manufacture in the size in which a typical scintillator is manufactured. Resultantly, the photomultipliers have a smaller light receiving face (50) than a light emitting face (46) of the scintillators (44). The present application contemplates inserting a reflective material (52) between the solid state photomultipliers (48). Instead of being wasted, light that initially misses the photomultiplier (48) is reflected back by the reflective material (52) and eventually back to the radiation receiving face (50) of the photomultiplier (48).

摘要： A positron emission tomography apparatus (100) includes a plurality of radiation sensitive detector systems (106) and selective trigger systems (120). The selective trigger systems identify detector signals resulting from detected gamma radiation (310) while disregarding spurious detector signals (310). In one implementation, the apparatus (100) includes a time to digital converter which decomposes a measurement time interval (T max ) according to a binary hierarchical decomposition of level H, where H is an integer greater than equal to one.

摘要： PROBLEM TO BE SOLVED: To provide a method and a system in which a catheter in the living body is photographed, a large burden is not applied to a patient, and at the same time, an operater can obtain much information. SOLUTION: This ultrasonic imaging system is equipped with an ultrasonic oscillator, an image processing unit to obtain a three-dimensional ultrasonic image of the patient, and the catheter to perform a medical treatment or a diagnosis insertion in the body of the patient. The catheter and utensils are required for performing the normal treatment. Three ultrasonic wave receivers which detect a scanning signal of the oscillator and are located with a distance from each other, are attached to a tip of the catheter. The distance between the oscillator and the receivers can be calculated by the running period of the scanning signal. Therefore, measurement of a space position of the receivers becomes possible, and an image screen for all of the three catheters can be selected from three-dimensional ultrasonic data. The tip of the catheter is automatically searched, and is displayed on a monitor without a manual moving of the oscillator.
