An assembly for a thermoplastic preform for securing body part is provided. The thermoplastic preform is deformable when heated to a softening temperature by an external heating source and hardens when cooled below the softening temperature. The assembly includes the thermoplastic preform and a protective cover surrounding the thermoplastic preform. The thermoplastic preform is sealed within the protective cover. The protective cover is heat resistant up to a temperature that exceeds the softening temperature for the thermoplastic preform. The protective cover transfers heat from the external heating source to the thermoplastic preform and prevents airborne and waterborne bacteria from contacting the thermoplastic preform.

Embodiments of the present disclosure provide a method and an apparatus of locating a tumor. The method includes: obtaining a position of a positioning mark before the patient's head moves, a position of a positioning mark after the patient's head moves, and a position of the tumor before the patient's head moves, wherein the positioning mark is disposed at a preset position of the body surface of the patient's head; determining a position of the tumor after the patient's head moves according to the position of the positioning mark before the patient's head moves, the position of the positioning mark after the patient's head moves, and the position of the tumor before the patient's head moves.

Systems and methods are described for the monitoring of patient motion via the detection of changes in capacitance, as measured using a capacitance position sensing electrode array. The changes in capacitance may be processed to determine a corresponding positional offset, for example, using a calibration data set relating capacitance to offset for each electrode of the array. The detected positional offset may be employed to provide feedback to a surgeon or operator of a medical device, or directly to the medical device for the control thereof. A medical procedure may be interrupted when the positional offset is detected to exceed a threshold. Alternatively, the detected positional offset may be employed to manually or automatically reconfigure a medical device to compensate for the detected change in position. Various configurations of capacitive position sensing devices are disclosed, including embodiment in incorporating capacitive sensing electrodes with a mask or other support structure.

The present specification discloses a radiation therapy protective eye mask for covering a patient's eyes, with the radiation therapy protective eye mask being placed over the eyes and beneath an immobilization mask. The radiation therapy protective eye mask includes a radiation shielding layer configured to cover at least one eye when a patient is undergoing radiotherapy treatments. A first layer of material can be positioned between the radiation shielding layer and the eyes, to provide cushioning and barrier between the radiation shielding layer and the skin. The radiation therapy protective eye mask can include a concave portion over the eyes to permit opening and closing of the eyes. Further radiation shielding layer can include structural and/or surface features and contours to reflect at least some of the radiation. In this way, the present eye protector reduces the quantity of radiation incident on the eyes for reducing eye damage.
