X-ray CT apparatus and X-ray detector

An X-ray CT apparatus comprising:

• a fixed part;
• a rotating part configured to be rotatably attached to the fixed part to rotate around a subject;
• an irradiator arranged in the rotating part;
• a detector arranged in the rotating part, and configured to detect X-rays emitted from the irradiator and generate an analog signal;
• an analog-to-digital converter arranged in the rotating part, and configured to convert the analog signal to a digital signal;
• a data transmitter arranged in the rotating part, and configured to receive the digital signal from the analog-to-digital converter;
• and
• a data receiver arranged in the fixed part, and configured to receive the digital signal transmitted from the data transmitter, wherein
• signals are wirelessly transmitted and received in at least a part between the detector and the analog-to-digital converter or between the analog-to-digital converter and the data transmitter.

An X-ray CT apparatus comprising:

• a fixed part;
• and
• a rotating part configured to be rotatably attached to the fixed part to rotate around a subject;
• wherein
• the fixed part includes a data receiver,
• the rotating part includes an irradiator, an X-ray detector, and a data transmitter,
• the X-ray detector including:
• a detector configured to detect X-rays emitted from the irradiator, and generate an analog signal,
• an analog-to-digital converter configured to convert the analog signal to a digital signal,
• a data-transfer radio-wave transmitter, and
• a data-transfer radio-wave receiver,
• the data-transfer radio-wave transmitter receives the digital signal transmitted from the analog-to-digital converter, converts the digital signal received into radio waves of a predetermined frequency, and wirelessly transmits the radio waves to the data-transfer radio-wave receiver,
• the data-transfer radio-wave receiver receives the radio waves transmitted from the data-transfer radio-wave transmitter, generates digital signal based on the radio waves received, and transmits the digital signal generated to the data transmitter, and
• the data transmitter receives the digital signal transmitted from the data-transfer radio-wave receiver, and transmits the digital signal received to the data receiver.
