Abstract: A method of medical image registration is to be implemented by a computer device, and includes steps of: obtaining an ultrasound target image corresponding to an area of interest in an ultrasound image; for each of multiple computed tomography (CT) images, obtaining a CT candidate image that corresponds to an area of interest in the CT image; for each of the CT candidate images, calculating a similarity between the CT candidate image and the ultrasound target image; making one of the CT candidate images that corresponds to the greatest similarity among the CT candidate images serve as a CT target image; and performing image registration on the ultrasound target image and the CT target image.

Abstract: A low dust linear module includes a rail unit, a slide seat unit, a dustproof strip and two magnetic members. The two magnetic members are disposed at the two slide seat end portions of the slide seat, the first magnetic attraction gap is defined between the magnetic attraction area and a corresponding one of the magnetic members, and the second magnetic attraction gap is defined between the magnetic attraction area and the slide seat cover. When the dustproof strip passes through and are magnetically attracted by the magnetic members, a gap will appear between the magnetic members and the slide seat and the slide seat cover, so that the magnetic members and the dustproof strip are kept in a gap without friction, so as to avoid the generation of dust due to friction, so that the linear module can operate normally and maintain the standard of the working environment.

Abstract: A linear transmission device includes: an elongated shaft member, a moving module, a rolling unit, a return assembly, a sensor and a data receiving unit. The linear transmission device has a simple structure. The sensor is disposed at the junction of the first return pipe and the second return pipe of the return assembly to timely detect the change in the distance between the rolling elements, which can determine whether there is an abnormality in the shape of the spacers. With the sensor outputting detecting signals, it can stop the terminal immediately to confirm the condition of the workpieces and the machine, avoiding the structural damage of the machine and the workpiece caused by the continuous operation. The sensor can also serve as a medium for transferring data, further facilitating maintenance.

Abstract: A linear guideway includes a rail, a slider disposed on the rail, and a load passage formed between the rail and the slider. The slider has two non-load passages penetrating through two opposite end surfaces of the slider. Each of two ends of each non-load passage is provided with a force sensor. Two end caps are disposed on two opposite end surfaces of the slider respectively and each have two circulation grooves. Each circulation groove is connected to an end of the load passage and an end of the non-load passage to form a circulation channel for balls to move therein. As a result, the linear guideway of the present invention employs force sensors to sense the force-receiving state of two ends of the non-load passages when they are impacted by the balls, so that it can be determined that if the balls have an abnormal pressing state.

Abstract: A linear module includes: a base, a slide stage, two support frames, two retaining units and a steel belt. With the pivoting freedom given by the guide portions of the retaining units, when the slide stage moves, the rolling elements can be abutted more closely against the contact surface of the steel belt via the pivoting of the guide portions, so as to reduce the occurrence of deformation and clearance produced by the steel belt, which not only improves the sealing performance of the steel belt and operation smoothness of the linear module, but also produces a dust proof effect, thus achieving the purposes of automatically adjusting contact angle, preventing deformation while extending the life of the steel belt.
