Problems solved by technology

However, if a shielding substance adheres to grip member of the electronic cassette discussed in Japanese Patent Application Laid-Open No. 2009-237074, the strength of a radio wave is lowered; moreover, when the grip member is grasped by the operator, radio communication is blocked.
A similar problem exists with U.S. Pat. No. 7,696,722.

Embodiment Construction

[0019]Various exemplary embodiments, features, and aspects of the invention will be described in detail below with reference to the drawings.

[0020]FIG. 1A is a front view of an X-ray imaging apparatus (hereinafter referred to as electronic cassette 10) according to an exemplary embodiment. FIG. 1B is a cross-section view taken along line A-A in the electronic cassette 10 according to an exemplary embodiment. FIGS. 2A and 2B are a front view and a perspective view of the electronic cassette 10 according to a modified example of an exemplary embodiment, respectively.

[0021]An X-ray sensor housing 11 of the electronic cassette 10 is configured to be held by an operator's hand 100. As illustrated in FIG. 1A, the operator's hand 100 grasps a grasping portion of the handle unit 13, by placing the operators fingers into an opening 14 of the handle unit 13. More specifically, the handle unit 13 includes a frame unit, namely the frame formed by the portion grasped by the operator's hand and t...

Abstract

A radiation imaging apparatus includes an imaging unit and a handle unit detachably attached to the imaging unit. The imaging unit includes a digital radiation detector including a detection area, a housing incorporating the digital radiation detector, a power arranged on one side surface of the housing, and a display unit arranged on the one side surface and configured to indicate a state of the digital radiation detector. The handle unit includes a frame unit covering at least part of each of three side surfaces other than the one side surface of the housing and a grasping portion forming an opening between the handle unit and at least part of the one side surface, with the handle unit attached to the imaging unit.

Description

BACKGROUND[0001]1. Field of Invention[0002]The present application is generally related to radiation imaging, and more particularly the present application is related to an X-ray imaging apparatus equipped with a novel handle unit.[0003]2. Description of Related Art[0004]X-ray imaging, an imaging technique in which a subject is irradiated with X-rays and a film-screen is used to detect the intensity distribution of the X-rays passing through the subject in order to obtain X-ray image of the object, is well known. Nowadays, the imaging method has been shifted from the conventional film-screen method to a digital radiography (DR) method using an imaging apparatus (a plat panel detector (FPD)) including a plane sensor on which pixels of minute photoelectric conversion elements and switching elements are arranged in a checkered pattern. The advantages of the DR method are that a stable X-ray image is obtained even if the amount of X-ray exposure is varied because the plane sensor in a F...
