| 摘要 |
The present invention provides a headrest apparatus (33) (and associated method), which includes a means for sensing a degree of contact (35) between a subject's head and the headrest and means for providing sensory feedback (150) based on the degree of contact. The apparatus includes a means for receiving at least one portion of the head (106) of the subject or patient, such as the forehead, and may include additional means for receiving another portion of the head, such as the chin. The apparatus (33) is adjustable in multiple directions to accommodate physical characteristics of the patient's head or to place the patient's head in a desirable position for observation or treatment. In use, the contact-sensing means (35) is used to determine whether or not the patient has moved his or her head away from the head-receiving means (106), and the sensory feedback means (150) is used to alert the patient of his or her movement out of contact with the head-receiving means (106) so that the patient may respond by re-establishing and maintaining the necessary contact. The present invention also provides a treatment system (15) (and associated method) which includes the headrest apparatus (33) and a means for irradiating tissue within a region of the head of the patient, such as ocular or corneal tissue. |
