Abstract: A new cartridge for a marker delivery device used in radiotherapy is provided. The cartridge has a transparent cartridge body that holds the marker inside it and permits external visual observation of the marker, and has an outer tube that is fitted on an outer circumference of the cartridge body, the outer tube is slidable in the longitudinal direction of the cartridge body, with this outer tube's sliding the cartridge body is exposable. The marker delivery device is suitable for implanting the marker in a flexible coil shape, made of X-ray-opaque or ultrasonic-wave opaque metal into the human body. And the cartridge of the device is capable of implanting a coil-shaped marker long enough in size compared with that of tissues, which permits, in marker-assisted ultrasonic imaging, to assess the size of the tissues accurately.

Abstract: In a color thermal printer, a thermal head has an array of heating elements, arranged in a main scan direction, for thermal recording to respectively pixels on thermosensitive recording material. The recording material is moved relative to the thermal head in a sub scan direction crosswise to the main scan direction, to record an image to the recording material according to image data. The recording material includes two lateral edges, opposed to each other, for extending in the sub scan direction. In the thermal printer, the image is recorded in a region extending to the two lateral edges on the recording material according to the image data. Density of two edge portions of the image disposed along the two lateral edges are lowered by processing the image data, to prevent occurrence of scorch on the two lateral edges.

Abstract: A protective tool for a therapeutic material delivery device prevents wrong sticking of the outer needle of the device after use and prevents dissipation of blood adhering to the outer needle and comprises a cover (8′A) and a cap (61) or stopper (65) attached to a forward end of said cover for protecting the forward end of the outer tubular needle (2A), wherein said cover (8′A) is formed of a plurality of tubes (8′A1, 8′A2, 8′A3, . . .
