Title: Forecast coding device
Inventor: TANAKA AKIYOSHI
IPC: H04N1/41
Filed: 1983-09-29
Abstract: PURPOSE:To improve a compressing rate by using a density difference after a value reading a picture is converted into the density so as to apply picture conversion. CONSTITUTION:An original picture element 211 to be converted and picture elements 212 after the conversion and preceding one picture element are converted respectively into density at density converters 23, 24 in order to convert a multi- gradation picture and code the picture after the conversion. When the difference of the density is within a prescribed range, the value after the conversion of the picture element to be converted is brought into the same value as that after the conversion and preceding one picture element. When the difference of the densities is at the outside of a prescribed range, the value after the conversion is brought into the same value as that of the original picture element and the picture element after the conversion is applied with forecast coding, Thus, the deterioration of picture quality both for the light and dark parts is less and the forecast hit rate of the picture after conversion is improved.

Title: Ect apparatus
Inventor: HIROSE YOSHIHARU
IPC: G01T1/161
Filed: 1984-08-30
Abstract: PURPOSE:To reduce an artifact, by correcting data affected by the variation in the total amount of the radioactive isotope (RI) in a subject. CONSTITUTION:A large number of radiation detectors 1, 2, ... n are arranged around a subject 10 in a ring form and the output of each detector is sent to a coincidence circuit 11. The coincidence detected by the circuit 11 is counted at every sampling period by a count circuit 15. The average value of total count values at every sampling period is calculated by CPU13 and the deviation of the total count values at every sampling period is further calculated and each data obtained during a sampling period is corrected corresponding to said deviation. Because the total count number of coincidences in each sampling period corresponds to the total amount of RI, even if the total amount of RI in the subject varies timewise, said amount is converted to a data value should be obtained in the case of no variation. By using the corrected data, the re- constitution of an image having no artifact is enabled.
