Abstract: Whether a phenomenon of photon incidence on detectors is a double event or a single event is determined (step S1). When it is a double event, emission data is collected (S2), and is put to an image reconstruction process (S3). When it is a single event, on the other hand, the data is collected as data for calibration (S4), and is put to a calibration process (S5). Since the data for calibration is collected during a clinical practice, a PET apparatus can be calibrated frequently without lowering the operating ratio of the apparatus.

Abstract: A discrimination parameter calculation method for photon detectors in this invention, applies two types of fitting functions which approximate waveforms of count numbers relative to energy ratios to the data having accumulated output waveform signals, and calculates fitting parameters of both the fitting functions. Based on both the fitting parameters, count numbers which are 1/n of peaks of both the fitting functions, and a value of the energy ratio of both the fitting functions corresponding to the count numbers is calculated as discrimination parameter k. Thus, whatever kind first photon detecting elements 35 and second photon detecting elements 37 may be, since discrimination parameter k is automatically calculated based on the fitting parameters after carrying out a fitting with the fitting functions, the discrimination parameter can be calculated with high accuracy.

Abstract: The function of an accumulated amount deriving part 14 can obtain the variation with time of the accumulated amount in the subject based on the radiopharmaceutical in a condition being separated for each radiopharmaceutical, that is, the second variation with time that is a function of the accumulated amount using the first variation with time that is a variation with time of a projection data measured by the projection data deriving part 10. The accumulated image acquisition part 15 acquires the accumulated image of each radiopharmaceutical to be provided for nuclear medicine diagnosis based on the second variations with time separated in this way, enabling the nuclear medicine diagnosis in administration of a variety of radiopharmaceuticals.

Abstract: An image sensing apparatus senses an image by illuminating a document by a light source including three light emitting diodes which emit light of red, green, and blue so that the light reflected from the document is incident on a sensor array which in turn generates an electric signal corresponding to the incident light, wherein a predetermined light emitting diode is also turned on during a period in which no image sensing operation is performed thereby making it possible to stabilize the intensity of light illuminating an image. Thus, the invention provides a high-performance and small-sized image sensing apparatus at a low cost.

Abstract: A stepping motor preferably applied to an image reading motor for a facsimile device or the like, drives the rotation with low noise by repeating turning-on and turning-off switching of the driving voltage in the stepping motor when a change of the exciting phase in the stepping motor is not continued for a constant time and performing the repeated switching for a predetermined cycle. At the same time the present motor can prevent the passage of current through all of four phase coils by the manner that a pair of phases in the stepping motor are not simultaneously driven.

Abstract: An image processor includes a first write device which serially inputs each of plural kinds of color component data for each pixel, and writes each color component data into a first line buffer for each line. A second write device reads in a unit of a line for each color component data written in the first line buffer, and writes each color component data corresponding to the plural lines into a second line buffer having a storage capacity which is larger than that of the first line buffer. A conversion device performs longitudinal-to-lateral conversion by using each color component data corresponding to the plural lines written in the second buffer. An output device serially outputs a visible image representing each color component data corresponding to the plural lines converted by the conversion device.

Abstract: An easy-to-use image forming apparatus and method which uses either a monochrome recording cartridge or a plurality of colors recording cartridge, which, when recording an image desired by a user, does not require the user to perform unnecessary operations regarding replacement of a cartridge, change of the kind of recorded image, or selection of a form. A determination is made as to whether or not a correct cartridge is attached based on the kind of the currently attached cartridge and the image desired by the user. When it is determined that the correct cartridge is attached, recording is initiated. When it is determined that the correct cartridge is not attached, a notification prompting replacement is provided to the user. When the user instructs color reading or monochrome reading of the original, a recording operation is carried out by changing the size of the image to an appropriate size in response to the kind of recorder, original size and form size.

Abstract: In an image forming apparatus, plural LED light sources are provided for emitting lights of respectively different wavelengths, and, in reading an illuminated image with a reading sensor, a lighting mode setting register selects a first mode for reading the image with a single color or a second mode for reading the image with plural colors. The light emitting time of these light sources are set by a light emitting time control register, a light emitting time counter and an automatic light emitting time adjustment circuit, and the currents supplied to the light sources are set by a lighting current control circuit. A CPU controls these circuits according to the selected mode.
