For example, if a patient accidentally turns a head when taking an X-ray film, the photo taken at this time will have a problem of angular deviation, which makes the subsequent tracking diagram difficult to make. When the twilight is taken, the patient will wear a skull fixator. The skull holder is a structure similar to a headphone, but the earmuff portion has an elongated protrusion, and the protrusion is inserted into the ear canal to limit the angle of rotation of the patient's skull. The skull fixer can only limit the angle of rotation of the patient's head, but it does not limit the inclination of the patient's head. If the doctor needs a frontal (P〇ster_teri〇r View) supplemental light film for treatment, the projection error caused by the patient's head tilt will seriously affect the correctness of the subsequent track map and the skull analysis. SUMMARY OF THE INVENTION Accordingly, it is an aspect of the present invention to provide a detection module for measuring head rotation angle and tilt angle. According to an embodiment of the invention, the detection module comprises at least: a carrier, an accelerometer, an electronic compass, a small LCD flat panel, and a transmission interface, wherein the carrier is worn on the head of the user, and The accelerometer and the electronic compass are placed on the carrier. The accelerometer is used to measure the user's head 201000075. The electronic compass is used to measure the angle of rotation of the user's head, while the male & 传送 is used to receive the tilt angle and the angle of rotation. The system and the small LCD flat panel display instantly display the measured head angle. In accordance with another embodiment of the present invention, the transport interface includes a wireless transmission, and the medium wireless transmission module is electrically coupled to the accelerometer and the electronic compass' to utilize electromagnetic waves to transmit rotational angles and tilt angles to the external system. [Embodiment] Referring to FIG. 2 and FIG. 3 at the same time in FIG. 2, FIG. 2 is a block diagram showing the power module of the detecting module 100 for measuring the angle of rotation and the tilt angle of the skull according to the first embodiment of the present invention. 3 is a schematic view showing the structure of a display 109 according to a first embodiment of the present invention. The angle detecting module 1 includes a carrier (not shown in FIG. 2), an accelerometer 1〇4, an electronic compass 1〇6 transmission interface, and a display 109' in which the carrier is worn on the user's head. And the display 109 includes a display screen 109a. The accelerometer 1〇4 and the electronic compass 106 are disposed on the carrier to detect the angle of rotation and the angle of inclination of the user's skull. The transfer interface 108 is electrically coupled to the accelerometer 1〇4 and the electronic compass 106. The transfer interface 108 can receive the rotational angle and tilt angle measured by the accelerometer 104 and the electronic compass 1〇6 and output it to an external system. When the external system receives the head rotation angle measured by the wireless sensing module, the head rotation angle can be displayed through the preset human-machine interface. In the present embodiment, the 'external system is constructed using a general desktop computer or a pen-type computer' and is connected to the transmission interface 201000075 by means of a USB interface. Through the controller and the wireless transmission module, the display 109 (for example, a small lcd flat display panel) that displays the rotation angle on the module can be instantly turned on and output to the computer screen and stored in the database. Therefore, the doctor or X-ray photographer can know the change in the patient's head angle through a small LCD flat panel or a human-machine interface on the computer side and perform appropriate processing. For example, X-ray photographers can instantly correct the position of the skull according to the change of the patient's head angle to capture the Twilight # with a small offset angle. For example, the doctor can use the image according to the change of the patient's head angle. The system performs image compensation on the digitized X-ray film to obtain an X-ray film with a small offset angle. Referring to 帛4®', the structure of the accelerometer 104 according to an embodiment of the present invention is shown. The accelerometer 1〇4 includes at least a thermometer 104a, a heater 104b and a processor 104c, wherein the thermometer 1 is disposed at four corners of the accelerometer 104, and the heater 1 is disposed in the middle of the thermometer 104a for heating The gas in the accelerometer 1〇4. When the accelerometer 104 is tilted in a certain direction, the heated gas can still maintain a vertical upward movement with the surface level due to the gravity of the earth. At this time, the four thermometers l4a around, because of the proximity of the hot air, There will be different temperature changes. The accelerometer 104 uses the degree of this temperature change to convert the angle at which the object is tilted. Please refer to FIG. 5, which is a schematic structural view of an electronic compass 106 according to an embodiment of the invention. The electronic compass 1〇6 includes a magnetoresistive detector 1〇6a and a power supply circuit 106b, wherein the magnetoresistive detector 1〇6a calculates the rotation angle 0 of the electronic compass 106 by the change of the magnetic resistance, and the power supply circuit丨〇6b is 201000075 for supplying power to the magnetoresistive detector 106a. In the present example, the electronic compass 106 utilizes a flux gate principle to measure the angle of rotation. However, in other embodiments of the invention, the electronic compass can also utilize the Hall effect to detect Look at the angle of rotation. Please refer to FIG. 6, which is a schematic structural view of a carrier 150 according to an embodiment of the present invention. In this embodiment, in order to be able to use the detection module to wear on the skull, the carrier 15〇 is designed as a hat, and the shape of the hat 〇# matches the shape of the user's skull to prevent the hat from loosening. The accuracy of the detection module 100 is affected. In addition, the cap is made of an X-ray transparent material such as plastic. Furthermore, the carrier according to the invention may also be designed with a frame and/or a belt for securing the detection module 1 to the user's head. It is worth noting that the display ι〇9 can be placed on the side of the debt testing module 100 to facilitate the reading of the angle value by the photographer. Referring to Fig. 7, there is shown a functional block diagram of a detecting module 2A for measuring a turning angle and a tilting angle of a skull according to a fifth embodiment of the present invention. The angle detecting module 200 is similar to the angle detecting module 1〇〇ci. When the user's head is rotated, if the cable is transmitted by the user, the user may be hindered during the movement and the entire angle detection is emphasized. The weight of the module is therefore preferably transmitted to the external system by wireless transmission of the user's cranial angle. In this embodiment, the transmission interface 108 of the angle detection module includes the wireless transmission module 2〇2. The wireless transmission module 2〇2 is electrically connected to the accelerometer 1〇4 and the electronic compass 1〇6 to transmit the rotation angle measured by the accelerometer 104 and the electronic compass 1〇6 by the electromagnetic wave and the inclination angle of 201000075. In this embodiment, the upper computer or the notebook computer is provided with wireless reception, such as the data transmitted by the table transmission module 2G2. Wireless transmission I 2 and the wireless receiving module use the same communication protocol, such as communication protocol, Bluetooth wireless transmission. ❹
